Product Description

The SST 25 series Serial Flash family features a four-wire, SPI-compatible interface that allows for a

low pin-count package which occupies less board space and ultimately lowers total system costs.

SST25VF064C SPI serial flash memory is manufactured with SST proprietary, high-performance

CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain bet-

ter reliability and manufacturability compared with alternate approaches.

The SST25VF064C significantly improves performance and reliability, while lowering power consump-

tion. The device writes (Program or Erase) with a single power supply of 2.7-3.6V. The total energy

consumed is a function of the applied voltage, current, and time of application. Since for any given volt-

age range, the SuperFlash technology uses less current to program and has a shorter erase time, the

total energy consumed during any Erase or Program operation is less than alternative flash memory

technologies.

The SST25VF064C device is offered in 16-lead SOIC (300 mils), 8-contact WSON (6mm x 8mm), and

8-lead SOIC (200 mils) packages. See Figure 2 for pin assignments.

Memory Organization

The SST25VF064C SuperFlash memory array is organized in uniform 4 KByte erasable sectors with

32 KByte overlay blocks and 64 KByte overlay erasable blocks.

Device Operation

The SST25VF064C is accessed through the SPI (Serial Peripheral Interface) bus compatible protocol.

The SPI bus consists of four control lines; Chip Enable (CE#) is used to select the device, and data is

accessed through the Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK).

The SST25VF064C supports both Mode 0 (0,0) and Mode 3 (1,1) of SPI bus operations. The difference

between the two modes, as shown in Figure 3, is the state of the SCK signal when the bus master is in

Stand-by mode and no data is being transferred. The SCK signal is low for Mode 0 and SCK signal is

high for Mode 3. For both modes, the Serial Data In (SI) is sampled at the rising edge of the SCK clock

signal and the Serial Data Output (SO) is driven after the falling edge of the SCK clock signal.

Figure 3: SPI Protocol

Reset/Hold Mode

The RST#/HOLD# pin provides either a hardware reset or a hold pin. From power-on, the RST#/

HOLD# pin defaults as a hardware reset pin (RST#). The Hold mode for this pin is a user selected

option where an EHLD instruction enables the Hold mode. Once selected as a hold pin (HOLD#), the

RST#/HOLD# pin will be configured as a HOLD# pin, and goes back to RST# pin only after a power-off

and power-on sequence.

Reset

If the RST#/HOLD# pin is used as a reset pin, RST# pin provides a hardware method for resetting the

device. Driving the RST# pin high puts the device in normal operating mode. The RST# pin must be

driven low for a minimum of TRST time to reset the device. The SO pin is in high impedance state while

the device is in reset. A successful reset will reset the status register to its power-up state (BPL, BUSY

and WEL = 0; BP3, BP2, BP1, and BP0 = 1). See Table 2 for default power-up modes. A device reset

during an active Program or Erase operation aborts the operation and data of the targeted address

range may be corrupted or lost due to the aborted erase or program operation.

Hold Operation

The EHLD instruction enables the hold pin functionality of the RST#/HOLD# pin. Once converted to a

hold pin, the RST#/HOLD# pin functions as a hold pin until the device is powered off and on. After the

power cycle, the pin functionality returns as a reset pin (RST#) after the power on.

The HOLD# pin is used to pause a serial sequence using the SPI flash memory, but without resetting

the clocking sequence. To activate the HOLD# mode, CE# must be in active low state. The HOLD#

mode begins when the SCK active low state coincides with the falling edge of the HOLD# signal. The

HOLD mode ends when the HOLD# signal’s rising edge coincides with the SCK active low state.

If the falling edge of the HOLD# signal does not coincide with the SCK active low state, then the device

enters Hold mode when the SCK next reaches the active low state. Similarly, if the rising edge of the

HOLD# signal does not coincide with the SCK active low state, then the device exits from Hold mode

when the SCK next reaches the active low state. See Figure 5 for Hold Condition waveform.

Once the device enters Hold mode, SO will be in high-impedance state while SI and SCK can be VIL or VIH.

If CE# is driven high during a Hold condition, the device returns to Standby mode. As long as HOLD#

signal is low, the memory remains in the Hold condition. To resume communication with the device,

HOLD# must be driven active high, and CE# must be driven active low. See Figure 5 for Hold timing.

Figure 5: Hold Condition Waveform

Write Protection

SST25VF064C provides software Write protection. The Write Protect pin (WP#) enables or disables

the lock-down function of the status register. The Block-Protection bits (BP3, BP2, BP1, BP0, and BPL)

in the status register provide Write protection to the memory array and the status register. See Table 5

for the Block-Protection description.

Write Protect Pin (WP#)

The Write Protect (WP#) pin enables the lock-down function of the BPL bit (bit 7) in the status register.

When WP# is driven low, the execution of the Write-Status-Register (WRSR) instruction is determined by

the value of the BPL bit (see Table 3). When WP# is high, the lock-down function of the BPL bit is disabled.

Security ID

SST25VF064C offers a 256-bit Security ID (Sec ID) feature. The Security ID space is divided into two

parts – one factory-programmed, 64-bit segment and one user-programmable 192-bit segment. The

factory-programmed segment is programmed at SST with a unique number and cannot be changed.

The user-programmable segment is left unprogrammed for the customer to program as desired.

Use the Program SID command to program the Security ID using the address shown in Table 7. Once

programmed, the Security ID can be locked using the Lockout SID command. This prevents any future

write to the Security ID.

The factory-programmed portion of the Security ID can never be programmed, and none of the Secu-

rity ID can be erased.

Status Register

The software status register provides status on whether the flash memory array is available for any

Read or Write operation, whether the device is Write enabled, and the state of the Memory Write pro-

tection. During an internal Erase or Program operation, the status register may be read only to deter-

mine the completion of an operation in progress. Table 4 describes the function of each bit in the

software status register.

Busy

The Busy bit determines whether there is an internal Erase or Program operation in progress. A ‘1’ for

the Busy bit indicates the device is busy with an operation in progress. A ‘0’ indicates the device is

ready for the next valid operation.

Write Enable Latch (WEL)

The Write-Enable-Latch bit indicates the status of the internal memory Write Enable Latch. If the

Write-Enable-Latch bit is set to ‘1’, it indicates the device is Write enabled. If the bit is set to ‘0’ (reset),

it indicates the device is not Write enabled and does not accept any memory Write (Program/Erase)

commands. The Write-Enable-Latch bit is automatically reset under the following conditions:

•Power-up

•Write-Disable (WRDI) instruction completion

•Write-Status Register instruction completion

•Page-Program instruction completion

•Dual-Input Page-Program instruction completion

•Sector-Erase instruction completion

•Block-Erase instruction completion

•Chip-Erase instruction completion

•Program SID instruction completion

•Lockout SID instruction completion

Block Protection (BP3,BP2, BP1, BP0)

The Block-Protection (BP3, BP2, BP1, BP0) bits define the size of the memory area, as shown in Table

5, to be software protected against any memory Write (Program or Erase) operation. The Write-Status-

high or the Block-Protect-Lock (BPL) bit is 0. Chip-Erase can only be executed if Block-Protection bits

are all 0. After power-up, BP3, BP2, BP1 and BP0 are set to the defaults specified in Table 5.

Block Protection Lock-Down (BPL)

WP# pin driven low (VIL), enables the Block-Protection-Lock-Down (BPL) bit. When BPL is set to 1, it pre-

vents any further alteration of the BPL, BP3, BP2, BP1, and BP0 bits. When the WP# pin is driven high

(VIH), the BPL bit has no effect and its value is “Don’t Care”. After power-up, the BPL bit is reset to 0.

Security ID Status (SEC)

The Security ID Status (SEC) bit indicates when the Security ID space is locked to prevent a Write

command. The SEC is ‘1’ after the host issues a Lockout SID command. Once the host issues a Lock-

out SID command, the SEC bit can never be reset to ‘0.’

Instructions

Instructions are used to read, write (Erase and Program), and configure the SST25VF064C. The

instruction bus cycles are 8 bits each for commands (Op Code), data, and addresses. The Write-

Enable (WREN) instruction must be executed prior any Page-Program, Dual-Input Page-Program,

Sector-Erase, Block-Erase, Write-Status-Register, Chip-Erase, Program SID, or Lockout SID instruc-

tions. The complete list of instructions is provided in Table 6.

All instructions are synchronized off a high to low transition of CE#. Inputs will be accepted on the ris-

ing edge of SCK starting with the most significant bit. CE# must be driven low before an instruction is

entered and must be driven high after the last bit of the instruction has been shifted in (except for

Read, Read-ID, and Read-Status-Register instructions). Any low to high transition on CE#, before

receiving the last bit of an instruction bus cycle, will terminate the instruction in progress and return the

device to standby mode. Instruction commands (Op Code), addresses, and data are all input from the

most significant bit (MSB) first.

Read (33 MHz)

The Read instruction, 03H, supports up to 33 MHz Read. The device outputs the data starting from the

specified address location. The data output stream is continuous through all addresses until termi-

nated by a low to high transition on CE#. The internal address pointer will automatically increment until

the highest memory address is reached. Once the highest memory address is reached, the address

pointer will automatically increment to the beginning (wrap-around) of the address space. For example,

once the data from address location 7FFFFFH has been read, the next output will be from address

location 000000H.

The Read instruction is initiated by executing an 8-bit command, 03H, followed by address bits A23-A0.

CE# must remain active low for the duration of the Read cycle. See Figure 6 for the Read sequence.

Figure 6: Read Sequence

High-Speed Read (80 MHz)

The High-Speed Read instruction supporting up to 80 MHz Read is initiated by executing an 8-bit com-

mand, 0BH, followed by address bits A23-A0and a dummy byte. CE# must remain active low for the

duration of the High-Speed Read cycle. See Figure 7 for the High-Speed Read sequence.

Following a dummy cycle, the High-Speed Read instruction outputs the data starting from the specified

address location. The data output stream is continuous through all addresses until terminated by a low

to high transition on CE#. The internal address pointer will automatically increment until the highest

memory address is reached. Once the highest memory address is reached, the address pointer will

automatically increment to the beginning (wrap-around) of the address space. For example, once the

data from address location 7FFFFFH is read, the next output is from address location 000000H.

Fast-Read Dual-Output (75 MHz)

The Fast-Read Dual-Output (3BH) instruction outputs data up to 75 MHz from the SIO0and SIO1pins.

To initiate the instruction, execute an 8-bit command (3BH) followed by address bits A23-A0 and a

dummy byte on SI/SIO0. Following a dummy cycle, the Fast-Read Dual-Output instruction outputs the

data starting from the specified address location on the SIO1and SIO0lines. SIO1outputs, per clock

sequence, odd data bits D7, D5, D3, and D1; and SIO0outputs even data bits D6, D4, D2, and D0.

CE# must remain active low for the duration of the Fast-Read Dual-Output instruction cycle. See Fig-

ure 8 for the Fast-Read Dual-Output sequence.

The data output stream is continuous through all addresses until terminated by a low-to-high transition

on CE#. The internal address pointer will automatically increment until the highest memory address is

reached. Once the highest memory address is reached, the address pointer automatically increments

to the beginning (wraparound) of the address space. for 64 Mbit density, once the data from address

location 7FFFFFH has been read the next output will be from address location 000000H.

is initiated by executing an 8-bit command (BBH) on SI/SIO0, thereafter, the device accepts address

bits A23-A0 and a dummy byte on SI/SIO0and SO/SIO1. It offers the capability to input address bits

A23-A0 at a rate of two bits per clock. Odd address bits A23 through A1 are input on SIO1and even

address bits A22 through A0 are input on SIO0, alternately For example the most significant bit is input

first followed by A23/22, A21/A20, and so on. Each bit is latched at the same rising edge of the Serial

Clock (SCK). The input data during the dummy clocks is “don’t care”. However, the SIO0and SIO1pin

must be in high-impedance prior to the falling edge of the first data output clock.

Following a dummy cycle, the Fast-Read Dual I/O instruction outputs the data starting from the speci-

fied address location on the SIO1and SIO0lines. SIO1outputs, per clock sequence, odd data bits D7,

D5, D3, and D1; and SIO0outputs even data bits D6, D4, D2, and D0 per clock edge. CE# must remain

active low for the duration of the Fast-Read Dual I/O instruction cycle. The data output stream is con-

tinuous through all addresses until terminated by a low-to-high transition on CE#.

The internal address pointer will automatically increment until the highest memory address is reached.

Once the highest memory address is reached, the address pointer automatically increments to the

beginning (wraparound) of the address space. For example, once the data from address location

7FFFFFH is read, the next output is from address location 000000H. See Figure 9 for the Fast-Read

Dual I/o sequence.

Page-Program

The page-Program instruction programs up to 256 bytes of data in the memory. The selected page

address must be in the erased state (FFH) before initiating the Page-Program operation. A Page-Pro-

gram applied to a protected memory area will be ignored.

Prior to the program operation, the Write-Enabled (WREN) instruction must be executed. CE# must

remain active low for the duration of the Page-Program instruction. The Page-Program instruction is

initiated by executing an 8-bit command, 02H, followed by address bits A23-A0. Following the address,

at least one byte is needed for the data input. CE# must be driven high before the instruction is exe-

cuted. The user may poll the Busy bit in the software status register or wait TPP for the completion of

the internal self-timed Page-Program operation. See Figure 10 for the Page-Program sequence.

For Page-Program, the memory range for SST25VF064C is set in 256 byte page boundaries. The

device handles shifting of more than 256 bytes of data by keeping the last 256 bytes of data shifted as

the correct data to be programmed. If the target address for the Page-Program instruction is not the

beginning of the page boundary (A7-A0 are not all zero) and the number of data input exceeds or over-

laps the end of the address of the page boundary, the excess data inputs will wrap around and will be

programmed at the start of that target page.

Dual-Input Page-Program (50 MHz)

Dual-Input Page-Program instruction A2H, doubles the data input transfer of normal Page-Program

instruction and supports up to 50MHz. Data to be programmed is entered using two I/O pins, SIO1and

SIO0. Prior to the program operation the Write-Enable (WREN) instruction must be executed. The

Dual-Input Page-Program instruction is entered by driving CE# low, followed by the instruction code,

A2H, three address bytes, and at least one data byte on serial data inputs SIO1and SIO0pins. CE#

must be driven low for the entire duration of the sequence. The Dual-Input Page-Program instruction

programs up to 256 bytes of data in the memory. The selected page address must be in the erased

state (FFH) before initiating the Page-Program operation. A Dual-Input Page-Program applied to a pro-

tected memory area will be ignored.

CE# must be driven high after the seventh and eight bit of the last data byte has been latched; other-

wise, the dual input program instruction is not executed. Once CE# is driven high the instruction is exe-

cuted and the user may poll the WEL and Busy bit of the software status register or wait TPP for the

completion of the internal self-timed Page-Program operation. See Figure 10 for the Dual-Input-Page-

Program sequence.

For Dual-Input Page-Program, the memory range for the SST25VF064C is set in 256 byte page

boundaries. The device handles shifting of more than 256 bytes of data by keeping the last 256 bytes

of data shifted as the correct data to be programmed. If the target address for the Page-Program

instruction is not the beginning of the page boundary (A7-A0 are not all zero) and the number of data

input exceeds or overlaps the end of the address of the page boundary, the excess data inputs will

wrap around and will be programmed at the start of that target page.

Chip-Erase

The Chip-Erase instruction clears all bits in the device to FFH. A Chip-Erase instruction will be ignored

if any of the memory area is protected. Prior to any Write operation, the Write-Enable (WREN) instruction

must be executed. CE# must remain active low for the duration of the Chip-Erase instruction sequence.

Initiate the Chip-Erase instruction by executing an 8-bit command, 60H or C7H. CE# must be driven high

before the instruction is executed. Poll the Busy bit in the software status register or wait TCE for the comple-

tion of the internal self-timed Chip-Erase cycle. See Figure 15 for the Chip-Erase sequence.

Figure 15:Chip-Erase Sequence

Read Security ID

To execute a Read SID operation, the host drives CE# low, sends the Read SID command cycle (88H),

one address cycle, and then one dummy cycle. Each cycle is eight bits long, most significant bit first.

After the dummy cycle, the device outputs data on the falling edge of the SCK signal, starting from the

specified address location. The data output stream is continuous through all SID addresses until termi-

nated by a low-to-high transition on CE#. The internal address pointer automatically increments until

the last SID address is reached, then outputs wrap around until CE# goes high.

Lockout Security ID

The Lockout SID instruction prevents any future changes to the Security ID. Prior to the Lockout SID

operation, the Write-Enable (WREN) instruction must be executed. To execute a Lockout SID, the host

drives CE# low, sends the Lockout SID command cycle (85H), then drives CE# high. A cycle is 8 bits

long, most significant bit first. The user may poll the BUSY bit in the software status register or waits

TPSID for the completion of the Lockout SID operation.

Program Security ID

The Program SID instruction programs one to 24 bytes of data in the user-programmable, Security ID

space. The device ignores a Program SID instruction pointing to an invalid or protected address, see

Table 7. Prior to the program operation, execute WREN.

To execute a Program SID operation, the host drives CE# low, sends the Program SID command cycle

(A5H), one address cycle, the data to be programmed, then drives CE# high. The programmed data

must be between 1 to 24 Bytes and in whole Byte increments. To determine the completion of the inter-

nal, self-timed Program SID operation, poll the BUSY bit in the software status register, or wait TPSID

for the completion of the internal self-timed Program SID operation.

Read-Status-Register (RDSR)

The Read-Status-Register (RDSR) instruction allows reading of the status register. The status register

may be read at any time even during a Write (Program/Erase) operation. When a Write operation is in

progress, the Busy bit may be checked before sending any new commands to assure that the new

commands are properly received by the device. CE# must be driven low before the RDSR instruction is

entered and remain low until the status data is read. Read-Status-Register is continuous with ongoing

clock cycles until it is terminated by a low to high transition of the CE#. See Figure 16 for the RDSR

instruction sequence.

Write-Enable (WREN)

The Write-Enable (WREN) instruction sets the Write-Enable-Latch bit in the Status Register to ‘1’

allowing Write operations to occur. The WREN instruction must be executed prior to any Write (Pro-

gram/Erase) operation. The WREN instruction may also be used to allow execution of the Write-Sta-

tus-Register (WRSR) instruction; however, the Write-Enable-Latch bit in the Status Register will be

cleared upon the rising edge CE# of the WRSR instruction. CE# must be driven high before the WREN

instruction is executed.

Figure 17:Write Enable (WREN) Sequence

Write-Disable (WRDI)

The Write-Disable (WRDI) instruction resets the Write-Enable-Latch bit to ‘0,’ thereby, preventing any

new Write operations. The WRDI instruction will not terminate any program or erase operation in prog-

ress. Any program or erase operation in progress will continue after executing the WRDI instruction.

CE# must be driven high before the WRDI instruction is executed.

Enable-Write-Status-Register (EWSR)

The Enable-Write-Status-Register (EWSR) instruction arms the Write-Status-Register (WRSR)

instruction and opens the status register for alteration. The Write-Status-Register instruction must be

executed immediately after the execution of the Enable-Write-Status-Register instruction. This two-

step instruction sequence of the EWSR instruction followed by the WRSR instruction works like soft-

ware data protection (SDP) command structure which prevents any accidental alteration of the status

high before the EWSR instruction is executed.

Write-Status-Register (WRSR)

The Write-Status-Register instruction writes new values to the BP3, BP2, BP1, BP0, and BPL bits of

the status register. CE# must be driven low before the command sequence of the WRSR instruction is

entered and driven high before the WRSR instruction is executed. See Figure 19 for EWSR or WREN

and WRSR instruction sequences.

Executing the Write-Status-Register instruction will be ignored when WP# is low and BPL bit is set to

‘1’. When the WP# is low, the BPL bit can only be set from ‘0’ to ‘1’ to lock-down the status register, but

cannot be reset from ‘1’ to ‘0’. When WP# is high, the lock-down function of the BPL bit is disabled and

the BPL, BP0, BP1, BP2, and BP3 bits in the status register can all be changed. As long as BPL bit is

set to ‘0’ or WP# pin is driven high (VIH) prior to the low-to-high transition of the CE# pin at the end of

the WRSR instruction, the bits in the status register can all be altered by the WRSR instruction. In this

case, a single WRSR instruction can set the BPL bit to ‘1’ to lock down the status register as well as

altering the BP0, BP1, BP2, and BP3 bits at the same time. See Table 3 for a summary description of

WP# and BPL functions.

The 8-bit command, AAH, Enable-Hold instruction enables the HOLD functionality of the RST#/

Read-ID (RDID)

The Read-ID instruction (RDID) identifies the device as SST25VF064C and manufacturer as SST. The

device information can be read from executing an 8-bit command, 90H or ABH, followed by address

bits A23-A0. Following the Read-ID instruction, the manufacturer’s ID is located in address 00000H and

the device ID is located in address 00001H. Once the device is in Read-ID mode, the manufacturer’s

and device ID output data toggles between address 00000H and 00001H until terminated by a low to

high transition on CE#. After CE# is driven high, the device is put into standby mode.

Power-Up Specifications

All functionalities and DC specifications are specified for a VDD ramp rate of greater than 1V per 100

ms (0V to 3V in less than 300 ms). If the VDD ramp rate is slower than 1V/100 ms, a hardware reset is

required. The recommended VDD power-up to RESET# high time should be greater than 100 µs to

ensure a proper reset. See Table 16 and Figures 26 and 27 for more information.
