Datasheet

Product Featu res

The Intel® Wire less Flas h Me m o ry (W 3 0 ) de vice co m b in es state-of-the-ar t In te l® Flash technology to

p rovide a versatile memory solution f o r high performa nce, low pow er, board constraint mem ory

applications. The W30 flash memory de vice off ers a multi-partition, dual-operation flash architecture

that enables the flash dev ice to read from one partit ion whil e programming or erasing in another partition.

This Read-While-Write or Read-W hile-Erase capabil ity makes it possible to ac hieve higher data

throughput rates com pared to single partition devices. Tw o processors can interleave code execution,

b ecause program and erase operations can now occur as background pro cesses.

The W30 flash memory device inc orp or ates an Enh anc ed Fac tory Pr ogram min g (EFP) m ode to impr ove

12 V factor y pr ogram ming perfo rma nce . This f eatur e hel ps eli min at e manu factu ri ng bott le necks asso ci ated

with program ming high-density flash memory devices. The EFP program time is 3.5 µs per word,

compared to the standard fac tory program tim e of 8.0 µs per wo rd, so EFP mode saves significant factory

p rogramming time for improved factory efficiency.

The W30 flash memory device also includes block lock-down and programmabl e WAIT s ignal polarity,

and is supported by an ar ray of softw are tools.

1.3 Conventions

The fol lowing abbreviated terms an d phrases are used throughout this documen t:

•1.8 V refers to the VCC operating voltage range of 1.7 V – 1.9 V (except where noted).

•3.0 V refers to the VCCQ operating voltage range of 2.2 V - 3.3 V.

•VPP =12V refers to 12 V ± 5%.

•When referring to register s, the term set mean s the bit i s a logi cal 1 , and cleared means the bit

is a logical 0.

•The terms pin and signal are often used interchangeably to refer to the external signal

connections on the package. (Ball is the ter m u s ed for BG A ) .

•A word i s 2 b yt es, or 16 b i t s .

•Signal names are i n all CAPS (for exam p le, WAIT).

•Voltage appli ed to the signal is subscripted (for example, VPP).

Throughout this docume nt, refere nces are made to top, bottom, parameter, and partit ion. To clarif y

thes e re ferences, the fol lowing convent ions have been adopted:

•A block is a group of bits (or words) that era s e s im ultaneous ly with one block erase

instruction.

•A main block contains 32 Kwords.

•A para meter b l o ck contains 4 Kwords.

•The Block Base Address (BBA) is the firs t addr ess of a block.

•A partition is a group of block s that share eras e and pr ogram circuitry and a common st atus

•The Partition Base Address (PBA) is the first address of a partition. For example, on a

32- Mbit top-paramet er flash device, partition number 5 has a PBA of 0x140000.

•The top partition is located at the highest physica l flash devi ce address . This partition can be

a main part ition or a paramet er pa rtition.

•The bottom partition is locat ed at the lowest physical flash device address. This partition ca n

be a main pa rtition or a param eter partition.

•A main partition contains only main blocks.

•A parameter partitio n conta ins a mixture of main blocks and paramete r blocks.

•A top parameter device (TPD) has the paramete r partit ion at the t op of the memory m ap with

the pa ramete r blo cks at t he top of tha t parti tion. This flash dev ice t ype was former ly refer red to

as a top-boot flash device.

•A bot t om parameter devi ce (BPD) has the parameter partition at the bottom of the memory

map with the parameter bloc ks at the bottom of that partition. This flash device type was

forme rly referred to as a bottom - boot block flash device.

2.0 Functional Overview

This section provides an overview of the W30 flash memory device features an d arc hitecture .

2.1 Overview

The W30 flash memory dev ice provides Read-While-W ri te (RWW) and Read-Whi te-Erase (RWE)

capabili ty. This ca pability provides high-performa nce sync hronous and async hronous rea ds in

package-c omp atible densities usi ng a 16-bit data bus. Individually-erasable memory blocks are

optim ally sized for code and data storage. Eight 4-Kword parameter blocks are located in the

parameter partition at e ither the top or bottom of the memory m ap. The rest of the memory array is

gr ouped into 32-Kword main blocks.

The memor y archi tectu r e fo r the W30 fl ash memory device con sists of multiple 4-Mbit partitions,

the exact number depending on the flash device density. By dividing the memory array into

part iti ons, pr ogram or erase ope ration s can take place sim ultan eousl y during rea d operati ons. Bur st

r eads can traverse partition boundaries, but user application code is r es ponsible for ens uring that

burst reads do not extend into a partition that is actively progra mming or erasin g. Although each

partition has burst-rea d, write, and erase capabili ties, simultaneous operation is limite d to wr ite or

erase in one parti tion while other partit ions are in a read mode.

Augme nted erase-s uspend func tionality further enhances the RWW capabilities of the W30 flas h

me mory devic e. An erase can be suspe nded to perform a program or read operation within any

block, except a block that is eras e-suspende d. A program operation nested within a suspen ded

erase can subse quently be suspended to read yet another memory locatio n.

After power-up or reset, the W30 flash memory device defaults to as ynchronous rea d

configuration. Writing to th e flash memory devic e Read Configuration Regist er (RCR) enable s

synchronous burst-mode read operation. In synchronous mode, the CLK input increments an

internal burst address gen era tor. CLK also synchroni ze s the flash memory device with the host

CPU and outputs data on every, or on every other, valid CLK cycle after an initial latenc y. A

pr ogrammable WAIT output signals to the CPU when data from the flash memory device is read y.

I n addition to its improved architecture and interfa ce, the W30 flash memory devi ce inco rporates

Enha nced Factory Programming (EFP), a feature that enables fas t programming and lo w-power

designs . The EFP feature provides fa st progra m performance, which can increase the

ma nufac turing throughput of a fa ctory.

The W30 flash memory devic e support s read operati ons at 1.8 V and er ase and program oper ations

at 1.8 V or 12 V. With th e 1.8-V option, VCC and VPP can be tied together for an ultra - low-power

des ign. In addition to voltage flexi bility, the dedicated VPP input provides extens ive data

protection when VPP < VPPLK.

A 128- bit protect ion register ca n imp lement new security techniques and data prot ection schemes:

•A combination of factory-programmed and user-OTP data cells provide unique flash device

identification, he lp implement fraud or cloning prevention schemes, or help protect content.

•Zero-late ncy locking/unlocking on any memory block provide s instant and comp lete

pr otection for critical syste m co de and data.

•An additional block lock-down capability provides hardwa re protecti on where soft ware

com mands alone cannot cha nge the block prot ection status.

The fl ash dev ic e Co mman d Us er Int er f a ce (C U I) li n k s th e s y ste m pro c es sor to the in t e rn al fl ash

memory ope ration. A vali d com ma nd sequence written to the CUI initiates the flash device W rite

S tate Machine (WSM) opera tion, which automatically execute s the algorithms, timings , and

verifications necessary to manage fla sh memory program and erase. An internal status register

provides ready/busy indic ation results of the oper ation (success , fail, and so on).

Three power-sa ving feature s– Autom atic Power Savings (AP S ) , standby, and RST# – can

significantly reduce powe r cons um ption.

•The flash device automatically enters APS mode following read cycle completion.

•S tandby mode begins when the system desele cts the flas h memory by de-ass erting CE#.

•Driving RS T# low produces power savings simil ar to standby mode. It als o res ets the part to

read- arra y mode (important for system-level reset), clears internal s tatus registers , and

provides an additiona l level of flash device write protection.

2 .2 Memor y Ma p an d Pa rt iti on i n g

The W30 flash memory de vice is divided into 4-Mbit physica l partitions. This partitioning allows

simultaneous RWW or RW E operations, and enables users to segment code and data areas on

4-Mbit bo unda ries. The fl ash memory arr ay is as ymmetric ally bl oc ked, whic h enabl es syste m code

and data integr ation within a sing le flas h device. Each block can be eras ed independe ntly in block

eras e mode. S im ultaneous program and erase operations are not allowed; only one pa rtition at a

time can be active ly programming or erasing. See Table 1, “Bot tom Paramete r Memory Map” on

page 12 and Table 2, “Top Parameter Memory Map” on page 13.

•The 32-Mbit flash device has eight partitions.

•The 64-Mb it flash device has 16 partitions .

•The 128-Mbit flash device has 32 partitions.

Each flash device de nsity contains one para me ter partition a nd several main partitions . The 4-Mbit

parameter partition contai ns eigh t 4-Kword parameter bl ocks and se ven 32-Kword main blo cks .

Each 4- Mbit main partition contains eight 32- Kwor d blocks.

The bul k of the flash memory array is divided into main blocks that c an s tore code or data , and

parameter block s that allow sto r age of f requently upda ted small pa rameters that are normally

stored in EEPROM. By using software techniques, the word-rewrite functionality of EEPROMs

can be emulated.

Table 5. Signal Descriptions - µBGA Package & VF BGA Package (Sheet 1 of 2)

Symbol Type Name and Function

A[22:0] Input ADDRESS INPUTS: For memory addresses. 32 Mbit: A[20:0]; 64 Mbit: A[21:0]; 128 Mbit: A[22:0]

D[15:0] Input/

Output

DATA INPUTS/OUTPUTS:

• Inpu ts data and com mands during write cycles.

• Outputs data during reads.

Data pins are High-Z when the flas h device or its outputs are deselected. Data is internally latched

during writes.

ADV# Input ADDRESS VALID: AD V# indicates valid address presence on address inputs. During synchronous

read operations, all add resses are latc hed on the rising edge of ADV#, or the next valid CLK edge with

ADV# low, whichever occurs first.

CE# Input CHIP ENABLE:

• Asserting CE# activates internal control logic, I/O buffers, decoders, and sense amps.

• De-asserting CE# des elects the flash device, places it in standby mode, and tri- states all ou tputs.

CLK Input CLOCK: CL K synchronizes the flash device to the s y stem bus frequency during sy nchronous reads

and increments an internal address generator. During sy nchronous read operations, address es are

latched on ADV#’s rising edge or CLK’s rising (or falling) edge, whichever occurs first.

OE# Input OUT PUT ENAB LE:

• When asserted, OE# e nables the flash device output data buffers during a read cycle.

• When OE# is deasserted, data outputs are placed in a high-impedance state.

RST# Input RESET: When low, RST# resets internal automation and inhibits write operations. This reset provides

data protection during powe r transitions. De-asserting RST# enables no rmal operation and plac es th e

flash device in asynchronous read-array mode.

WAIT Output WAIT: Th e W A IT si gn al ind ica t es val i d d ata du rin g sy nc hr onou s r e ad mod es . It ca n b e c onfi gu red to be

asserted- high o r asserted-low, ba sed on bit 10 of the Read Configuration R egister. WAIT is tri-stat ed if

CE # is deasserted. WAIT is not gated by OE#.

WE# Input WRI TE ENABLE: WE# controls writes to the CUI and array. Addresses and data are latched on the

rising edge of WE#.

WP# Input WRITE PROTECT: Disables/enables the lock-down function. When WP# is asserted, the lock-down

mechanism is enabled and blocks ma rked lock-dow n cannot be unlocke d through software. See

Section 13.1, “Block Lock Oper ations” on page 73 for details on block locking.

VPP Power/

Input

ERASE AND PROGRAM POWER: A val id voltage on this pin allo ws erasing or progr amming. Flash

memory contents cannot be altered when VPP < VPPLK. Do not attempt block erase and program

operations at invalid VPP vo ltag es .

Set VPP = VCC for in-system program and erase operations. To accommodate resistor or diode drops

from the system supply, the VIH level of VPP can be as low as VPPL min. VPP must rema in above VPPL

min to perfor m in-system flash device modification. VPP can be 0 V during read operations.

VPPH can be applied to main blocks for 1000 cycles maximum and to parameter blocks for 2500 cycles.

VPP can be connected to 12 V for a cumulative total not to exceed 80 hours. Extended use of this pin

at 12 V migh t red uc e bl oc k cy c lin g ca pabilit y.

VCC Power FL ASH DEVICE POWER SUPPLY: Writes are inhibited at VCC < VLKO. Do not attempt flash device

operations at invalid VCC voltages.

VCCQ Power OUTPUT POWER SUPPLY: Enables all outputs to be driven at VCCQ.

VSS Power GROUND: Pins for all internal flas h device c ircuitry must be connected to system ground.

VSSQ Power OUTPUT GROUND: Provides ground to all outputs which are driven by VCCQ. This signal can be tied

directly to VSS.

DU — DO NOT USE: Do not use this pin. Do not connect this pin to any power supplies, signals, or other

pins; this pin must be floated.

NC — NO CONNECT: No internal connection; can be driven or floated.

Notes:

1. All currents are RMS unless noted. Typical values at typical VCC, TA = +25°C.

2. Aut omatic Power Sa vings (APS) reduces ICCR to approximately standby levels i n static ope ration. See ICCRQ

specification for details.

3. Sampled, not 100% tested.

4. VCC read + pr ogram curre nt is the sum of VCC read and VCC program currents.

5. VCC read + erase current is the sum of VCC rea d and VCC erase curren ts.

6. ICCES is specified with the flash device deselected. If the flash device is read while in erase s uspend, the c urrent is

ICCES plus ICCR.

7. VPP < VPPLK inhibits erase and program operations. Do not use VPPL and VPPH outside their valid ranges.

8. VIL can undershoot to –0.4V and VIH can overshoot to VCCQ+0.4V for durations of 20 ns or less.

9. If VIN>VCC the input load current increases to 10 µA max.

8.0 Power and Reset Specifications

Intel® Wi reless Flash Memory (W 30) devices have a layered approach to powe r savings that can

significantly reduce ove rall system power consumption.

•The APS feat ure re duces power consump tion when the flash device is selected but idle.

•If CE# is deasserted, the memory enters its standby mode, where c urrent consumpt ion is even

lower.

•Asserting RST# provides current sa vings similar to standby mode.

The combi nation of these feat ures can minimize m emory power consumption, and therefore,

overall syste m powe r cons um ption.

8.1 Active Power

With CE# at VIL a nd RST# at VIH, t he f l ash de vic e i s i n the activ e mo de. Ref er to Section 6.1, “DC

Cur r ent Character is tics” on page 27, for I CC value s. When the f lash device is in active state, it

cons umes the most power from the sy stem. Minimiz ing flash device act ive current therefore

reduces system power cons umpt ion, especially in battery-powered appli ca tions.

8.2 Automatic Power Savings (APS)

Automatic Power Saving (APS) provides low power operation during a re ad acti ve state . ICCAPS is

the ave rage curren t measured over any 5 ms time int erval, 5 µs af ter CE# is deasserted. During

APS, aver age current is measured over the same time interval 5 µs after t he foll o w ing events:

•There is no internal read, program or erase activity.

•CE# is asserted.

•The address lines are quiescent, and at VIL or VIH.

OE# can be driven during APS.

8.3 Standby Power

When CE# is dea sserted, the fl as h device is deselected and pla ced in standby, substantia lly

reducing power consumption. In standby, the da ta outputs are placed in High-Z, indepe ndent of the

level placed on OE#. Standby current, ICCS, is the average current measured over any 5 ms time

interval, 5 µs after CE# is de asserted. During standby, average current is mea su r ed ove r the same

time interval 5 µs afte r CE# is deasserted.

When the fla sh device is dese lecte d (whil e CE# is deasserte d) during a progra m or erase operati on,

it continue s to c onsume active power until the program or erase ope ration completes.

8.4 Power-Up/Down Characteristics

The flash device is protected agai nst acciden tal block erasure or programming during power

tr ansitions. Power supp ly sequencing is not required if VCC and VPP are connected together; so it

does not matter whether VPP or VCC powers-up first. If VPP is not connected to the system supp ly,

then V CC must attain VCCMIN before applying VCCQ and VPP. Do not drive flas h device inputs

before supply voltage = VCCQMIN. Power supply transitions can occur only when RST# is low.

8.4.1 System Reset and RST#

The use of RST# during system reset is im portant with automated program/erase flash devices,

because the system expects to read from the flash memory when it comes out of reset. If a CPU

r eset occ ur s without a flash memory r eset, the CPU is not properly initia lized, because th e f lash

me mory migh t be providing status information instead of arra y data.

Note: To allow proper CPU/flas h device ini tializa tion at system reset, connect RST# to the s ystem CPU

RESET# signal.

System d esigners must guard agai n st spuriou s writes when VCC vo ltages are abo v e VLKO.

Bec ause both WE# and CE# must be lo w for a command write, dri ving eit her si gnal to VIH inhi bit s

writes to the flash device. The CUI archi tecture provides additional protection, because memory

contents can be altered only after successful completion of the two-step comm and sequences.

The flash devic e is also di sabl ed until RS T# is br ought to VIH, regardless of its control input state s.

By holding the flash device in res et (RST# connected to sy stem PowerGood) during power-up/

down, invalid bus conditions duri ng power-up can be masked, pr oviding yet another level of

memory protection.

8.4.2 VCC, VPP, and RST# Transitions

The C U I la t ch es comm a nd s issued by s ystem software, and is not altered by VPP or CE#

transitions or WSM actions. Read-array mode is the power-up default state after the flash device

exits from reset mode or after VCC transitions above VLKO (Lockout voltage).

After complet ing program or b lock erase operation s (even after VPP transitions below VPPLK), t he

Read Array co mmand must reset the CUI to read-array mode if flash memory array access is

desired.

8.5 Power Supply D ecoupling

When the flash device is accessed, many internal c onditions ch ange. Circuits are ena bled to charge

pum ps and swit ch voltages. This internal activity produces transient noise.

To minimize the effe ct of this transient noise, device decoupling capacitors are required. Transi ent

current magnitudes depend on the flash device output capa citive an d inductive loading. Two-line

control and proper dec oupling capacitor selectio n sup pres ses these transient voltage pe aks.

Note: Eac h flash device must ha ve a 0. 1 µF ceramic capacitor connected between each power (VCC,

VCCQ, VPP), and ground (VS S , VSS Q ) sig nal. High-fre quency, inher ently low-inductanc e

capacitors must be as close as possible to t h e p acka g e signals.

9.0 Flash Device Operations

This chapter provides an overv iew of flas h device operati ons. The W30 flash memory device

f amily include s a n on-chip Write State Machine (WSM) to manage bloc k erase and program

algorithms. The WSM Command User Interface (CUI) allows minimal processor overhead with

RA M- like interface timings .

9.1 Bus Operations

9.1.1 Read

The W30 flash memory device has several read configurations:

•Asynchronous pa ge mode read.

•Syn chronous burst mo de read — outputs four, eight, sixteen, or continuous words, fr om main

blocks and parameter blocks.

Several read modes are available in each part ition:

•Read-array mode: read accesses retur n flash m emory array data from the addressed

locations.

•Read i d enti fier mode: reads return manuf acture r and devic e identi fier dat a, bloc k loc k statu s,

and protecti on register data . Identifie r information can be acce ssed starting at a 4-Mbi t

partition base addresses; the flash memory array is not acc essible in read id entifier mode.

•Read query mode: reads re tu rn th e flash device CF I d ata. CFI in formation can be accessed

starting at a 4-Mbi t partition ba se addresses; the flash memory array is not acces s ible in read

query m o de .

•Read status register m od e: reads return status regi ster data from the addressed partition. The

arr ay da ta fo r th at pa rt i ti o n is no t ac ce s si bl e. A sy s t em p r oc ess o r ca n che ck th e st atu s regi s t er

All partitions support the syn chronous burst mode that interna lly sequences addresses with respec t

to the input CLK to select and s upply data to the outputs.

Identifier codes, query data, and status regis ter r ea d operations execute as singl e-s ynchronous or

asynchronous read cycle s. WAIT is asserted durin g these read s.

Acce ss to the modes listed above is independent of VPP. An appropriate CUI co mmand places the

flash device in a read mode. At initial powe r-up or after reset, the flash device default s to

asynchronous read-array mode.

Asserting CE# enable s flash device read ope rations. The flash device int ernally decodes upper

addr ess inp uts to determine which part ition is acce ssed.

•Asserting ADV# opens the internal address latches.

•Asserting OE# activates the outputs, and gates the selected data onto the I /O bus .

•In as ynchronou s mode, the ad dress i s lat ched when ADV# i s dea ssert ed (when t he fla sh dev ice

is co nfigured to use ADV#).

•In sync hronous mode, the add ress is la tc hed by ei ther th e ri sing edge o f ADV# or the risi ng (or

falling) CLK edge while ADV# remains ass erted, whichev er occurs first.

WE# and RST# must be deass erted during read ope rations.

Note: If only as ynchronous reads are to be perform ed in your sy st em, CL K must be tied to a valid VIH

level, the WAIT signal can be floated, and AD V# must be tied to ground.

9.1.2 Burst Suspend

The Bu rst Sus pend fea ture al lows the sy stem to t empora rily s uspend a synchronous bur st oper ation

if the system needs to us e the flash device a ddress and data b us for other pu rpos es . Burst accesse s

can be suspended during the initi al latency (befo r e da ta is received) or after the flash device has

output data. When a burst ac cess is suspended, internal array sensing conti nues and any previously

latched internal dat a is retained .

Burst Suspe nd occurs when CE# is asserted, the curre nt address has been latched (either ADV#

risi ng edge or valid CLK edge), CL K is halted, and OE# is deasserted. CLK can be ha lted when it

is at VIH or VIL. To resume the burst ac ce ss, OE# is reasserted and CLK is restarted. Subsequent

CLK edges resume the burs t sequence where it left off.

W ithin the flash device, CE# gates the WAIT sig nal. Therefore, during Burst Suspend, WAIT

remains a ssert ed and d oes not re vert t o a hig h-impedance state wh en OE# is dea sserted. This WAIT

state can cause contenti on with another flash device attempting to control the system READY

signal during a Burst Suspend. System us ing the Burst Suspend feature must not connect the flash

device WAIT signal directly to the system READY signal.

Refer to Fi gure 15, “Burst Suspend” on page 39.

9.1.3 Standby

De-asserting CE# dese lects th e fla sh device and place s it in standby mode, substantially reduc ing

flas h device power cons umption. In sta ndby m ode, outputs are plac ed in a high-impedance state

independent of OE#. If deselected during a progr am or erase algorithm, the fla sh device consumes

active power until the program or erase operation completes.

9.1.4 Reset

The flash device enters a re se t m ode when RST# is ass erted. In reset mode, internal cir cuitry is

turned off and outputs are placed in a high-impedance state.

After returning from reset, a time tPHQV is required until outputs ar e val id, and a delay (tPHWV) is

r equired before a write sequence ca n be initiate d. After this wake-up interval, normal opera tion is

r estored. The fl ash devic e defa ults to read- array m ode, t he statu s regi ster is set t o 80h, a nd th e Read

Configuration Register defau lts to asynchronous page-m ode reads.

I f RST# is as s erted during an eras e or program operation, the ope ration aborts and the memory

contents at the a borted block or addre ss are invalid. See Figure 21, “Reset Operations Waveforms”

on pag e 47 for detailed information regard ing reset timings.

As on any automated device, RST# must be asserted during system reset. When the system comes

out of rese t, the process or expects to read from the flash memory array. Automated flash memory

devices provide status in formation when read during program or e rase operations. If a CPU reset

occurs with no flas h memory reset, the CPU might not be properly ini tialize d, because the flash

me mory devic e m ight be providing st atus information instead of arra y data. 1.8 Volt Int el Flash

me mory devic es allow proper CPU initializa tion following a system re s et through the use of the

RST# input. In this applicat ion, RST# is contr olled by the sa me CPU reset signal, RESE T#.

9.1.5 Write

A wr ite occur s when CE# and WE# are asserted and OE# is deass er ted. Flash memory co ntrol

com mands are written to the CUI using standard microprocessor write tim ings. Proper use of the

ADV# input is needed for proper latching of the addre sses. Refer to Section 7.3, “AC Write

Characteristics” on page 40 for det ails. T he add ress and data are l atche d on the risin g edge of WE #.

Write operations ar e asynchronous ; CLK is ignored (but can be kep t ac tive/toggling).

The CUI does not occupy an addressable memory location within any partition. The system

pr oce ssor must access it at the correct address ran ge, depending on th e kind of command executed.

Pro gramming o r eras ing can occur in only one part ition a t a time. Ot her part it ions mus t be in o ne of

t h e read modes or erase s u spend mod e.

Table 18, “Command Codes and Descriptions” on page 53 shows the av ailable commands.

Appendix A, “Write State Machine” on page 90 provides information about moving between

different opera ting modes using CUI comm ands.

9.2 Flash Device Commands

The flash device on-chip WSM manage s eras e and program algorithms. This local CPU (WSM)

controls the f lash device in -s ystem read, program, and era s e operations. Bus cycl es to or from the

f lash memory device c onform to standard microproc essor bus cycles. The RST#, CE#, OE#, WE#,

and ADV# cont rol signal s di cta te data flow into and out of the flash device. WAIT info rms the

CPU of valid data during burst reads. Table 17, “Bus Operations Summ ary” on page 50

summ arizes bus operations .

To select flash device ope rations, write specific commands into the flash device CUI. Table 18,

“Command Codes and Descriptions” on page 53 lis ts all poss ible command codes and

descriptions. Table 19, “Bus Cyc le Definitions ” on pa ge 55 list s command definitions. Because

com mands are partition-specific, you must iss ue write commands wit hin the target address range.

10.0 Read Operations

10.1 Read Array

The Read Array command places (or resets) the partition in read-array mode and is used to re ad

data fr om the flash memory array. Upon init ial flash device power-up, or after re set (RST#

transitions from VIL to VIH), all partitions default to asynchronous read-array m ode.

To read array data from the flash de vice:

1. Write the Read Array command (FF h) to the CUI and specify the desi red word address.

1. Read fro m that address.

Note: If a pa rtition is alre ady in read-array mode, you do not need to issue the Read Array comm and to

re ad f r om that partition .

If the Read Arra y com mand is wr itt en to a parti ti on that is e rasin g or pr ogramming , the fla sh devic e

pres ents invalid data on the bus until the program or er as e operation completes.

After the pr ogram or eras e finishes in that partition, valid array data can then be read. If an Erase

Suspend or Pro gram Su sp end command suspends the WSM, a subse quent Read Array command

places the addressed partition in read-array mode.

The Read Arra y com mand functions independent ly of VPP.

10.2 Read Device ID

The read identifie r mod e outputs the manufacturer/ device ide ntifier, block lock status , protection

regis ter codes, and conf iguration register dat a. The identifier in formation is con tained withi n a

sep arate memory s pace on the flash device, and can be acces sed along the 4-Mbit partition address

range supplied by the Read Identifier command (90h) address. Reads from addresses in Tab le 20

retrieve ID information. Issu ing a Read Identifier command to a part ition that is program mi ng or

erasin g pla ces the out puts of th at part ition in re ad ID mode whi le the pa rtiti on conti nue s to pro gram

or erase in the backgr ound.

10 .3 Read Query (CFI)

The W30 flash memory device contains a separate CFI query database that acts as an on-chip

d atasheet. To acce ss the CF I information wi thin the W30 flash memory device, issue th e Read

Query c ommand and supply a specific address.

The address is const ructed from th e base addre ss of a partition plus a part icular offset

corresponding to the desired CFI field.

Appendix B, “Common Flash Interface” on page 93 sho ws accessible CFI fields and their addre ss

of fsets. Issuing the Read Query comm and to a part ition that is programming or eras ing puts that

partition in read query mode whil e the partition continue s to program or erase in the background.

10.4 Read Status Register

The flash device status register displays program and erase operation status. The s tatus of a

partition can be read after writing the Read Status Register com mand to any location within the

address range of that parti tion. Read -status mode is the default read mode fol lowing a Program,

Erase, or Lock Block command sequence. Subsequent single reads from that partition ret urn the

partition s tatus unti l another valid command is written.

The r ead-status mode supports single s ynchronous and single asynchronous reads only; it does not

support burst read s.

The firs t falling edge of OE# or CE# latc hes and updates S tatus Regi ster data. T he ope ration does

not affect the modes of other partitions. Bec ause the S tatus Regis ter is 8 bits wide, only DQ [7:0]

contain valid status regis ter data; DQ [15:8] contain z eros. See Table 21, “Status Re gister

10.5 Clea r Sta tu s Reg ist er

The Clear Status Register command clears the status register and leaves all partition output states

unchanged. The WSM can set all status register bits and clear bits SR[7:6,2,0]. Because bits

SR[ 5,4,3,1] indicate various error conditions , they can be cleared only by the Clea r Status Re gis ter

comm and. By allowing system software to reset these bits, several operations (such a s

cum ulatively programmin g se veral addre sses or erasing mult iple blocks in sequence) can be

performed before reading the status register to determine whether an error occu rred.

I f an error is detected, the Status Regis ter must be cle ared before beginning another command or

sequence. Flash device reset (RST# = VIL) also clears the status register. This command functions

independent ly of VPP.

11.1 W ord Program

Wh e n th e Wor d Pr o g ram co mm an d is issued , th e WSM execu t es a sequ en ce of in t er n al ly tim e d

events to p r ogr am a word at the des ir ed address, and to verify that the b its are suff iciently

program m ed. Programming the fla s h me mo ry array changes specifically addressed bits to 0; 1 b its

do not change the memory cell conte nts.

Programming can occur in only one partition at a time. All other partitions must be in eit her a read

mode or erase s uspend mode. Only one partition can be in erase suspend mode at a time.

To examine the status register can be examined for program progress, read any a ddress within the

partition that is busy progra mming. However, while most status regist er bits are partition-s pecific,

th e Device WSM Status bit, S R[ 7], is device-specific. That is, if the status register is read from any

other partit ion, SR[7 ] indica tes the pro gram sta tus of the en tir e flash m emory dev ice. This s tatus bit

permits the system CPU to monitor the program progress while reading the status of other

partitions.

CE# or OE# toggl e (during polling) updates the status register. Several commands can be i ssued to

a partiti on that is pro gramm ing: Read Status Regi ster, Program Suspe nd, Rea d Identifier, an d Read

Query. The Read Array command can also be issued, but the read data is indeterminat e.

After programming compl ete s, three status register bits can signi fy various poss ible error

conditions:

•SR[4] indicates a program failure if set.

•If SR[3] is set, the WSM could not execute the Word Program command, because VPP was

outside the acceptable limits.

•If SR[ 1] is set, the progr am was abo r ted, becaus e the WSM attempted to program a locked

block.

After the sta tus register data is examined, clear it using the Clear Status Regis ter command before

issuing a new command. The partition remains in sta tus registe r mode until another command is

written to that pa rtition. Any command can be issued after th e s tatus register indic ates program

completion.

If CE# is deasserted while the flash device is programming, the flash devices do not enter standby

mode until the program operation complet es .

11.2 Factory Programming

The sta ndard factory programming mode uses the same commands and algorithm as the Word

Program mode (40h/10h). When VPP is at VPPL, program and era s e cu rrents are drawn through

VCC. If VPP is driven by a logic signal, VPPL must remain above the VPPLMin value to perfo rm

in-system flash memory modifications. When VPP is connected to a 12 V power supply, the flash

device draws program and erase c urrent direct ly from VPP, which elim inates the ne ed for a n

external swi tching trans istor to control the VPP voltag e.

Figure 37, “Examples of VPP Power S upply Configurations” on page 80 shows exa mp les of flash

device power supply us age in various configurations.

The 12-V VPP mode enhances programming performance during the short time period typically

found in manufacturing processes. Howe ver, this mod e is not intended for extended use.12 V can

be applied to VPP during progr am and era se operations as spec ified in Section 5.2, “Operating

Conditions” on page 26. VPP can be c onnected to 12 V for a total of tPPH hours maximum.

Stressing the flash device beyond the se limits mi ght cause permanent damage.

11.3 Enh an c ed Fact or y Pr o gram (E FP )

EFP substantially improves flash device programming perform anc e through a number of

enhancements to the conventional 12-Volt word program algorithm . The more e fficient WSM

algorithm in EFP eliminat es the traditional overhead delays of the conventional word program

mode in bot h the host pr ogra mming syst em and the f lash d evi ce. Ch anges to t he conve nti onal word

programming flowchar t and internal WSM routine were devel oped because of today's beat-ra te-

sen sitive manufacturing environments ; a balance between programming speed an d cycling

performance was attained.

The host programmer writ es data to the flash device and checks the Stat us Register to determine

when the dat a has compl eted progra mming. Thi s modification cuts wri te bus cycles approximately

in half.

•Following each internal program pulse, the WSM increments the flash device address to the

next phys ical loc ation.

•Progr amming e qui pment ca n t hen sequ ent ially stre am pr ogram d ata t hroughout an entir e b lock

without having to s etup and pre sent each new address.

In combin at ion, t hese enhancemen ts re duce m uch of t he hos t progra mmer ove rhead, enabl ing more

of a data streaming appr oach to flash device programming.

EFP further speeds up program mi ng by performing internal code verifi cation. With this feature,

PROM program mers can rely on the flash device to verify that it has be en programmed properly.

From the flash dev ice side , EFP stream lines inte rna l overhead by el imina ting the delays previous ly

assoc iated with switching voltages between programming and verify levels at each memory-word

location.

EFP cons ists of four phase s: setup, program, verify, and exit. Refer to Figure 29, “Enhanced

Factory Pro gram Fl owchart” on page 66 for a detailed graphical representation of how to

implement EFP.

11.3.1 EFP Requirements and Consider ations

11.3.2 Setup

After recei vin g the EF P Set up (30h) a nd EF P Conf irm (D0h) command sequenc e, SR[7] tra nsit ions

f rom a 1 to a 0, indi cating tha t the WSM is busy with EFP algorithm startup. A delay be fore

checking SR[7] is required to allow the WSM time to perform all of its setups and checks (VPP

level and block loc k st at us). If an error is detec te d, status register bits SR[4], SR[3], and/or SR[1]

are set, and the EFP operation terminates.

Note: Aft er the EFP Setup and Confirm com mand sequence, reads from the flash device autom atically

output status register data. Do not issue the Read Status Register command, because this command

is interpreted as data to program at WA0.

11.3.3 Program

After setup c ompletion, the host program ming system must check SR[0] to determine the

data-stream ready status (SR[0]=0). Each s ubsequent write after this check is a program-data wr ite

to the flash memory arra y. Each cell within the memory word to be programmed to 0 recei ves one

WSM pulse; additional pulses, if required, occur in the verify phase.

SR[0]=1 indicates that the WSM is busy applying the program puls e.

The host programmer must poll the flash device status register for the program done state after

each data-stream write.

SR[ 0]=0 indicates that the appr opriate cell(s ) within the accessed me mo ry location ha ve

r eceived the ir single WSM pr ogram pulse, and tha t the flash device is ready for the next word.

Although the host ca n chec k full status for errors at any time, this check is necessary only on a

block basis, after E FP exit .

Addres ses must remain within the target bloc k. Supplying an address outsi de of the target block

immediately terminates the program phase; the WSM then enters the EFP verify phase.

The addres s can either remain c onstant or inc r ement. The flash device compa r es the incoming

address to the address stored from the setup phase (WA0).

•If the addresses match, the WSM programs the new data word at the next sequential memory

location.

•If the addresses differ, the WSM jumps to the new address location.

The program phase concludes when the host programming system writes to a diffe rent block

address. The data supplie d must be FFFFh. Upon program phase completion, the flash device

enters the EFP verify phase.

11.3.4 Verify

A high percentage of the flash memory bits program on the first WSM pulse. However, EFP

in ternal verificat ion identifies ce lls that do not completely progr am on th eir first attempt, and

applies additional pulses as required.

The verify phase is ide ntical in flow to the program phase, except that instead of programming

in co min g data, the WSM compar es the v er ify-stream data to th e d ata t h at was previo u sly

programmed into the block.

•If the dat a co mpar es correctly, the host programmer proceeds to the next word.

•If the dat a does not match, the host waits while the WSM applies one or more additional

pulses.

The hos t pr ogrammer must reset its initial verify-word add ress to the sa me starting location

supplied durin g the program phase. It then reissues each data word in the same ord er as during the

program pha se. Like progra mming, the host can write each subsequent data word to WA0 or it can

increment through the block addresses.

The verification phase concludes when the interfacing program mer writes to a different block

address. The data supplied must be FF FFh. Upon completion of the verify pha se, the flash device

en ters the EF P exit pha se.

11.3.5 Exit

SR[7] =1 indicates that the fl ash device has returned to normal ope rating cond itions. Perform a ful l

status check at this time, to verify that the entire block programmed successfully. After EFP exit,

any val id CUI command can be issued.

12.0 Program and Erase Operations

12.1 Program/Erase Suspend and Resum e

The Program Suspend and Eras e Suspend commands halt an in-progr ess program or eras e

operation. The command can be is sued at any flash devic e addres s. The partition corresponding to

th e ad dress o f th e command remain s in i t s previous stat e. A sus p end command allows data to be

acc essed from memory locations othe r than the loca tion being programmed or the block be ing

erased.

•A program operation can be suspe nded only to perform a read ope ration.

•An erase operation can be suspended to perform either a program or a read operation within

any block, except the block that is erase suspend ed.

•A program comman d nes ted within a suspended eras e can subsequently be suspended to r ea d

yet another location.

Once a program or erase pro cess sta rts, the Suspe nd command reque sts tha t the WSM sus pends the

program or erase se quence at predet ermined points in the algorithm. The partition that is act ually

suspended conti nues to output st atus regist er data afte r the Suspend command is written. An

operation is suspended when status bits SR[7] and SR[6] and/or SR[2] are set.

To read data from blocks within the partition (other than an erase-suspended block), write a Read

Array command. Block erase cannot resume unti l the pr ogram operations initiated during erase

sus p en d are co mplet e.

•Read Array, Read Status Register, Read Identifier ( ID), Read Query, a n d Program Resume are

valid commands during Program or Erase Suspend.

•Additiona lly, Clear Status Register, Program, Program Suspend, Erase Resume, Lock Block,

Unlock Block, and Lock -Down Block are vali d com m ands during eras e s usp end.

To read data from a block in a partition that is not programming or erasing, the operation does not

need to be suspended.

•If the o ther pa rtitio n is alre ady in read array, ID, or Que ry mode , issuing a valid address returns

co r r esp on ding dat a.

•If the other partit ion is not in a read mode, one of the read commands must be issue d to the

partition befo re data can be read.

During a susp end, CE# = VIH places the fla sh de vice i n standby s tat e, whic h reduce s acti ve curre nt .

VPP must remain at its program level and WP# must remain unchanged while in su spend mode.

A resume command ins tructs the WSM to continue programming or erasing, and clears st atus

When read at the partition that is progr ammi ng or erasing, the fl as h device outp uts data

corresponding to the last mode for that parti tion. If the sta tus register error bits are set, th e status

regis ter can be cleared before issuing the next instruction. RST# must remain at VIH. See Figure

12.2 Blo ck Era se

The 2- cyc le block erase command sequence, consisting of Erase Setup (20h) and Erase Confirm

( D0h), initiates one block erase at the addressed block. Only one partition can be in an erase mode

at a ti me ; other partitions must be in a rea d mode . Th e Era se Confirm com mand internally latch es

the ad d r ess of th e bl o ck to er ase . Er ase f or c es al l b it s w it hi n the bl o ck to 1.

SR [7] is cl ear ed wh i le th e erase exec u te s .

Aft er writing the Erase Confir m command, the selected partition is placed in read status reg ister

mode . Reads pe rformed to th at partit ion return the current sta tu s data. The a ddres s given durin g the

Erase Confirm command does not need to be the same address used in the Er ase S etup command.

For example, if the Er as e Confirm command is given to partition B, then the selected blo ck in

partition B is erased, even if the Erase Setup command was to partition A.

The 2-cycle erase sequence cannot be interrupted with a bus write ope ration. For example, to

execute properly, an Erase Setup comm and m us t be immediately followed by the Erase Confirm

comm and. If a different comm and is issued between the setup and confirm comm ands, the

f ollowing occurs:

•The p ar t it io n is pl aced in re ad - st atu s mod e .

•The status register signals a comm and s equence error.

•All subsequent erase commands to that partition are ignored until the status register is cleared.

To detect block erase completion, the CP U analyzes SR[7] of that partition. If an error bit

(S R[5,3,1]) was flagged, the status register can be cleared by issuing the Clear Status Register

com mand before atte mpting the next operation. The partit ion remains in re ad-stat us mode until

another command is written to its CUI . Any CUI instruction ca n follow after erasing completes.

The CUI can be set to read-array mode to prevent inadverten t status register reads.

12.3 Read-While-Write and Read-While-Erase

The I nte l® Wireless Flash Memory (W30) s upports flexible multi-partition dual-operation

architec ture. By di viding the flash m emory into many se parate partitions, t he flash device can read

f rom one partition while programing (Read-Whil e-Writ e) or erasi ng (Read-While-Eras) in anothe r

partition. Both of these features greatly enh anc e dat a s torage performance.

The W30 flash memory device does not support simultaneous program and erase ope rations.

Attempting to perform operations such as these results in a command sequence error. Only one

partition can be progr am mi ng or erasing while another parti tion is reading. Howeve r, one partition

can be in erase suspend mode while a second partition is performing a program operation, and yet

13.0 Security Modes

The W30 flash memory device offe rs bot h hardware and software sec urity features to protect the

flash memory data.

•To use th e softw ar e secu rity f eature, execute the Lock Block command .

•To use the hardware security feature, execute the Lock-Down Block comm and and assert the

WP# signal.

Refer to Figu r e 3 3, “B lo ck Lo ck i n g Stat e D ia g ram” on pa g e 74 for a state diagram of the flash

device security features. Also see Figure 34, “Locking Operations Flowc hart” on page 77.

13.1 Block Lock Operations

Individual ins tant block locking protects code and data by allo wing any block to be locked or

unlocked with no latency. This locking schem e offers two leve ls of protection:

•Soft ware -only control of block locki ng (us eful for frequently changed data bl ocks ).

•Hardware interaction before locking can be ch anged (protects infrequently changed code

blocks).

The following s ections di scuss the l ocking syst em opera tio n. The t erm stat e [abc] specifies locking

states, such as state [001]. In this syntax:

•a= WP# value.

•b = block lock-down status bit D1.

•c = Blo ck Lo ck s tatus register bit D0.

Fig ure 33, “Block Locking State Diagra m” on page 74 defines possible locking states.

The fol lowing summarize s the loc king functionality.

•All blocks power-up in a locked state.

•Unlock commands can unlock thes e blocks, and lock co mmands can lock them again.

•The L oc k -D own comman d lo ck s a bl o ck an d prev ent s it fro m be in g unl o ck ed w h en W P# is

asserted.

— Locked-down blocks can be unlocked or locked with com mands as long as W P# is

deasserted.

— When WP# is asserted, previously locked-dow n blocks return to lock-down.

— The lock-do wn st atus bit clea rs only when the flash devi ce is reset or powe r ed-down.

Bl o ck lock registers are not af f ected by th e VPP level. The se r egisters can be modified and read

even if VPP < VPPLK.

The lockin g st atus of each bl ock can be set to locke d, unloc ked, and loc k-do wn, as describe d in the

following sections. See Figure 34, “Locking Operations Flowchart ” on page 77.

13.1.1 Lock

All blocks default to locked (st ate [x01]) afte r initial power-up or reset. Locked blocks are fully

pr otected from alteration. Attempted program or eras e operations to a locke d block return an error

in SR[1].

•To lock unloc ked blocks , us e the Lock Block command sequenc e.

•To change the statu s of a locked block to unlocke d or lock-down, use the appropriate software

commands.

13.1.2 Unlock

Unlocked blocks (s tates [x00] and [110]) can be programmed or erased. All unlocke d blocks return

to th e lo c ked state w h en th e f la s h de vi ce is res e t or po w e r ed - d o w n.

•To change the status of an unlocked block to th e locked or locked-down state , use the

appropriate software comm ands.

•To unlock a lo cked block, write the Unlock Block command se quence if the block is not

locked-down.

13.1.3 Lock-Down

Locked-down blocks (state [011]) offer an addi tional leve l of write protection beyond the

protec tion of a regula r locked block. If a bloc k is locked-down, the software cannot change the

state of the block if WP# is asserted.

•To lock-down a locked or unlocked bloc k, write the Lock-Down Block command sequence.

•If a block was set to loc ked-down, then later changed to unlocked, issue the Lock -down

comman d before assert ing WP#, to put that block back in th e locked-down state.

•Wh e n W P# is d ea ss er t ed , loc k ed - d o w n blo c ks cha n ge to th e lo ck e d st ate, and ca n th en be

unlocked usin g the Unlock Block comman d.

13.1.4 Block Lock Status

The lock status of eve r y block can be read in read ide ntifier mode.

Note: To enter this mode, issue the Read Identifier command to the flash device.

Subsequent reads at BBA + 02h output t he lock status of that block. For example, to read the bloc k

lock s tatus of block 10, the ad dres s sent to the flash device must be 50002h (for a top-parameter

device).

The lowest two da ta bits of the r ead data, DQ1 and DQ0, repr esent the lock status .

•DQ0 indicates t he block lock status. This bit is set using the Lock Block comm and and cleared

using the Block Unlock command. It is also set whe n entering the lock-down state.

•DQ1 indicates lock-down status and is set using the Lock-Down command.

The lock-down stat us bi t cannot be clear ed by s oftware–only by a flash de vice reset or

power-down. See Table 25.

13.1.5 Lock During Erase Suspend

Block lock configurations can be performed during an erase suspend operation, using the standard

locking command se quences to unloc k, lock, or lock-down a block . Thi s feat ure is useful when

another block requires immediate updating.

To change block locking during an erase operation:

1. Writ e th e Eras e Suspen d command .

2. Check SR[6] to determine that the eras e operation has suspe nded.

3. Write the desir ed loc k command sequenc e to a block.

The lock status changes.

4. After completing lock, unlock, read, or program operations, resum e the erase operation w ith

t h e Eras e Resu me comma n d (D0h) .

I f a bloc k is locke d or locked-down during a suspended erase of the s ame block, the locking status

bits change immediately. When the erase operation resumes, it completes normally.

Loc king oper ations cannot occur during program suspend. Appendix A, “Write State Machine” on

page 90 shows valid c omman ds during erase suspend.

13.1.6 Status Register Error Checking

Using nested locking or pr ogram command sequenc es during eras e s uspend can introduce

am biguity into sta tus register res ults.

Bec aus e locking changes require 2-cyc le command sequences—for example, 60h followed by 01h

to lock a block—following the Confi guration Setup command (60h) wit h an invalid comm and

produces a command sequence error (S R[5:4]=11b).

I f a Lock Block command error occ urs during erase suspend, the flash device sets SR[4] and SR[5]

to 1 eve n after the erase res um es . When erase is complete, possible errors dur ing the erase cannot

be det ected from the sta tus register, bec aus e of the previous locki ng command error. A similar

situation occurs if a program operation error is nested within an erase sus pend.

13.1.7 WP# Lock-Down Control

The Write P r otect signal, WP#, adds an a dditional la yer of block security. WP# affects only blocks

that previously had the Lock-Down command written to them.

•After the lock-do wn status bit is set for a block, asserting WP# forces that block into the

lock-down state [011] and prevents it fr om being unlocked.

•After WP# is deasserted, the state of the block reverts to locked [111]. Software commands

can then unlock the block (for erase or progra m operations) a nd subsequently re-lock it.

Only flash devic e reset or power-down can clear the lock-down status bit and render W P#

ineffective.

13.2 Protection Register

The W30 flash memory de vice inclu des a 128-bit Protectio n Register. This protection register is

use d to increase system security and for ide ntificatio n purposes. The protection register value can

match the flash device to the system CPU or ASIC to prevent flash device substitution.

•The l ower 64 bit s wit hin t he prote ction regis ter are programme d by Inte l wi th a uniq ue number

in ea ch fl as h d ev i ce .

•The upper 64 OTP bits within the protection register are le ft for the customer to program.

Once programmed, the cust omer segment can be locked to prevent further programming.

Note: The indivi dual bits of the user segment of the protection register are OTP, not the register in total.

The user can prog ram each OTP bit individually, one at a time, if desired. However, after the

protection reg ister is locked, the entire user segme nt is locked and no more user bits can be

programmed.

The protection register shares some of the same internal flash device resources as the parameter

partition. Therefore, RWW is allowed only between t he protection re gister a nd the main partitions.

Table 26 describes the operations allowed in the protection register, parameter partition, and main

partition during RWW and RWE.

13.3 VPP Protection

The I nte l® Wireless Flash Memory (W30) provides in- system pr ogram and era se at VPPL. For

factory programming, the W30 flash mem ory device also includes a low-cost, backward-

compatible 12 V programming feature.(See “Factory Programmin g” on page 63.) The EFP f eature

can also be used to greatly improve factory program perform ance, as explained in Se ct i on 11.3,

“Enhanced Factory Program (EFP)” on page 63.

I n addition to flexible block locki ng, holding the VPP programming voltage low can provide

hardware write protection of all fla sh - device blocks . If VPP is below VPPLK, program or erase

opera tions result in an error displayed in SR[3]. (See Figure 37.)

Note: If the VCC supply can sink adequate curr ent, you can use an appropriatel y valued r esistor.

14.0 Set Read Configuration Register

The Set Read Configuration Register (RCR) command sets the burst order, frequency

configuration, burst lengt h, and other parameters.

A two-bus cyc le command sequence initiates this operation . The read configuration register data is

plac ed on the lower 16 bits of the address bus (A[15:0]) during both bus cycles.

1. The Set Read Configuration Register command is written, along with the configuration data

(on the address bus ).

2. A seco nd wr ite confirm s the operation a nd again present s the read configuration register dat a

on the address b u s.

3. The read configuration register data is latched on the rising edge of ADV#, CE#, or WE#

(whichever occurs first).

This command functions i ndependently of the a pplied V PP volt age. Af ter executing this com ma nd,

the flash device returns to read-array mode.

To examine the contents of the read configuration register, write the Read Identifier command and

then read location 05h. (See Table 27 and Table 28.)

14.3 WAIT Signal Polarity (RCR[10])

•If the WT bit is c leared ( RCR[ 10]=0), then WAIT is configured to be ass erted low. A 0 on the

WAIT si gnal indicates that data is not ready and the da ta bus co ntains inva lid data.

•Conv er s el y, if RCR [ 1 0] is set, then WA IT is asser t ed hi g h.

In eithe r case, if WAIT is deas se rted, the n data is read y and valid. WAIT is asserted during

asy nchronous page mode reads .

14.4 WAIT Si gnal Function

The WAIT signal indi cates data valid wh en the flash devi ce is operating in syn chronous mode

(RCR[15]= 0), and whe n addre ssing a parti tion that is currently in read-array mode. Th e WAIT

signal is deasserted only when data is valid on the bus.

•When the flas h device is operating in synchronous non-read-ar r ay mode, such as read status ,

read ID, or read query, WAIT is set to an asserted state, as dete rm ine d by RCR[10]. See Figure

14, “WAIT Signal in Synchronous Non-Read Array Oper ation Waveform” on page 38.

•When the flash device is operating in asynchronous page mode or asynchronous single word

re ad mode, WAIT is set to an asserted state, a s determined by RCR[10]. See Figure 10, “Page-

Mode Read Operation Waveform” on page 34, and Figure 8, “Asynchronous Read Operation

Waveform” on page 32 .

From a system perspective, the WAIT signal is in the asserted state (based on RCR[10]) when the

flash device is operating in sync hronous non-read-array mode (such as Read I D, Read Query, or

Read St atus ), or if the flash de vic e is ope rating in async hronous mode (R CR[15]=1) . In the se c ases,

the s ys tem software must ignore (mask) the WAIT signal, bec ause WAIT does not conve y any

use f ul information about the validity of what is appearing on the data bus.

14.5 Data Hold (RCR[9])

The Data Outpu t Configura ti on (DOC) bit (RC R[9]) dete rmine s whether a da ta word re mains va lid

on the da ta bus for one or two clock cy cle s. The minimum data set-up tim e on the processor, and

the flash m emory clock-to-data output delay, determine whether one or two clocks are needed.

•A DOC s et at 1-clock data hold corresponds to a 1-clock data cycle.

•A DOC s et at 2-clock data hold corresponds to a 2-clock data cycle.

The setting of this config uration bit depends on the sy stem and CPU characterist ics. For

clar i fi c at io n , se e Figure 41. The following is a method for determining this configuration setting.

To set the flash device at 1-c lock data hold for subsequent reads, the foll owing condition must be

satisfied:

tCHQV (ns) + tDATA (ns) < One CLK Period (ns)

As an example, use a clock freq uenc y of 54 MHz and a cloc k period of 25 ns. Assume the data

output hold time is one clock. Apply this dat a to the formula above for the subsequent reads:

20 ns + 4 ns ≤ 25 ns

This equation is sat is f ied, and data output is available and val id at eve r y clock period. If tDATA is

long, hold for two cycles. During page-mode reads, t he initial acce ss time ca n be deter mi ned using

the f o rmu la :

tAD D- DELAY (n s )tDATA (ns) + tAVQV (ns)

Sub se quent reads in page mode ar e defi ned by:

tAPA (ns) + tDATA (ns) (minimum time)

14.6 WAIT Delay (RCR[8])

The WAIT configuration bit (RCR[8]) controls WAIT signal delay behavior for all synchronous

read-array modes. T his bit setti ng depends on the system and CPU cha r acteristics. The WAIT can

be asserted either during, or one data cycl e before, a va lid output.

In synchronous linear read array (no-wra p mode RCR[3]=1) of 4-word, 8-word, 16-word, or

continuous-word burst mode, an outp ut delay might occ ur when a burst se quence cross es its first

flash device-row boundary (16-word boundary).

•If the burs t s tart address is 4-word boundary aligned, the dela y does not occur.

•If the start address is misaligned to a 4-word bounda ry, the delay occurs once per burs t-mode

read sequence. The WAIT signal informs the system of this delay.

14.7 Burst Sequence (RCR[7])

The bu rst sequence specifie s t he s ynchronous -burst mode dat a order (see Table 30, “Seq uence and

B u rst Le ngth” on page 88 ). When operating in a linea r burs t mo de, either 4-word, 8-word, or

16- word burst lengt h with the burst wrap bit (RCR[3]) set, or in continuous burst mode, the flash

device might incur an output delay when the burs t sequence crosses the first 16-wo rd boundary.

(See F igure 39, “Word Boundary” on page 84 for word boundary description.)

Whether this delay occur s de pends on the star ting addres s.

•If the starting address is aligned to a 4-word bounda ry, there is no delay.

•If the starting addres s is th e e nd of a 4-wor d boundary, the output del ay is one clock cycle less

th an the Fir st Access Latency Count; this is the wor st- case delay.

The delay ta kes place only once, and only if the burst sequence crosses a 16-word bounda ry. The

WAIT pin informs the system of this delay. For timing diagrams of WAIT functionality, see the s e

figures:

•Fig ure 11, “Single Synchronous Read-Array Operation Waveform” on page 35

•Fig ure 12, “Synchronous 4-Word Burst Re ad Operation Wavefor m” on page 36

•Figure 13, “WAIT Functionality for EOWL (End-of-Word Line) Condition Waveform” on

14.9 Burst Wrap (RCR[3])

The bu rst wrap bit determines whether 4-word, 8- word, or 16-word burst accesses wrap within the

bur st -length boundary, or they cro ss word-length boundaries to per f orm linear accesses .

No-wrap mode (RCR[3]=1) enables WAIT to hol d of f the system pr ocess or, as it does in the

continuous burst mode, unt il valid data is available .

In no-wrap mode (RCR[ 3] =0), the flash device oper ates similarly to continu ous linear burst mode,

but consumes less power during 4-word, 8-word, or 16-word bursts.

For example, if RCR[3]=0 (wrap mode) and RCR[2:0] = 1h (4-word bur st), possible linear burst

sequenc es are 0-1-2-3, 1-2-3 -0, 2-3- 0-1, 3-0-1-2.

If RCR[3]=1 (no-wrap mode) and RCR[2:0] = 1h (4-word burst length), the n possible li near burst

sequenc es are 0-1-2-3, 1-2-3-4, 2-3-4-5, and 3-4-5-6. RCR[3]=1 not only enables li mited non-

aligned sequential bursts, but also reduces power by mini mi zing the number of internal read

operations.

Setting RCR[2:0] bits for continuous linear burst mode (7h) also achieves the above 4-word burst

seq uenc es. However, significant ly m ore power might be consum ed. The 1- 2-3-4 s equence, for

example, c onsumes power during the initial acces s , again during the internal pipeline lookup as the

processor reads word 2, and pos s ibly again, depe nding on system tim ing, near the end of the

sequence as the flash device pipelines the next 4-word sequenc e. RCR[3]=1 while in 4-word burst

mode (no-wrap mode) reduces this excess power cons um ption.

14.10 Burst Length (RCR[2:0])

The burst length is the number of words the fla s h device outpu ts in a synchronous read ac cess.

4-wor d, 8-word, 16-word, an d continuous-word are supported.

In 4-wor d, 8-word, or 16-word burst configuration, the burst wrap bit (RCR[3]) determines

whethe r burst accesses wrap within word-length boundaries, or they cross word-length boundaries

to pe r for m a linear access.

After an address is spec ified, the flas h device outp uts data until it reaches the en d of its burstable

address space. Continuous burst acces ses are lin ear only (burs t wrap bit RCR[3] is ignored dur ing

continuous burst) and do not wra p within word-length boundaries (see Table 30, “Sequence and

B u rst Le ngth” on page 88 ).

Appendix B Common Flash Interface

This appendix defi nes the data struc ture or database returned by the Common Flash Interfac e

(CFI) Query command. System software par se s this structure to gai n critical information, s uch as

block size, density, x8/x16, and electrical specifications.

Once th is inf ormati on has been obta ined, the s oftware c an determ ine whic h command sets to us e to

enable flash device writes, enable block eras es, and otherwise control the flash device . Th e Query

is pa rt of an ove rall specification for mul tiple command s et a nd control interface descriptions,

which is ca lled the Common Flash Interface, or CFI.

B.1 Query Structure Output

The Query database allows system software to obtain information for controlling the flash device.

This s ection describes the flash device CFI-compliant interface that allows access to Query data.

Query da ta are presented on the lowest-order data outputs (D Q0-7) only. The numerical offset

value is the address relative to the maximum bus width that the flash device supports. On the W30

family of flash memory devices, the Query table device starting address is a 10h, which is a word

address for x16 flash devi ce s.

For a word-wide (x16) flash device, the first two Query-st ructure byt es , ASCII Q and R, appear on

the low byte at word addresses 10h and 11h.

•This CFI-compliant flash device outpu ts 00h data on upper byte s.

•The flash device outputs ASCII Q in the low byt e (DQ0-7) and 00h in the high byte (DQ8-15).

At Query addresses c ontaining two or more bytes of information, the leas t significant data byte is

pres ented at the lower address, and the most s ignificant data byte is presented at t he higher addre ss.

In all of the following tables, addresses and data are represented in he xadecimal notation, so the h

suffix has been dropped. In addit ion, because the upper byte of word-wid e flash device s is always

00h, the leading 00 has been dropped from the table notation, and only the lower byte value is

shown. Any x16 flash device outputs can be assumed to have 00h on the upper byte in this mode.
