Product Description

The SST39VF640xB devices are 4M x16 CMOS Multi-Purpose Flash Plus (MPF+) manufactured with

SST’s proprietary, high-performance CMOS SuperFlash technology. The split-gate cell design and

thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate

approaches. The SST39VF640xB write (Program or Erase) with a 2.7-3.6V power supply. These

devices conform to JEDEC standard pin assignments for x16 memories.

Featuring high performance Word-Program, the SST39VF640xB devices provide a typical Word-Pro-

gram time of 7 µsec. These devices use Toggle Bit or Data# Polling to indicate the completion of Pro-

gram operation. To protect against inadvertent write, they have on-chip hardware and Software Data

Protection schemes. Designed, manufactured, and tested for a wide spectrum of applications, these

devices are offered with a guaranteed typical endurance of 100,000 cycles. Data retention is rated at

greater than 100 years.

The SST39VF640xB devices are suited for applications that require convenient and economical updat-

ing of program, configuration, or data memory. For all system applications, they significantly improve

performance and reliability, while lowering power consumption. They inherently use less energy during

Erase and Program than alternative flash technologies. The total energy consumed is a function of the

applied voltage, current, and time of application. Since for any given voltage range, the SuperFlash

technology uses less current to program and has a shorter erase time, the total energy consumed dur-

ing any Erase or Program operation is less than alternative flash technologies. These devices also

improve flexibility while lowering the cost for program, data, and configuration storage applications.

The SuperFlash technology provides fixed Erase and Program times, independent of the number of

Erase/Program cycles that have occurred. Therefore the system software or hardware does not have

to be modified or de-rated as is necessary with alternative flash technologies, whose Erase and Pro-

gram times increase with accumulated Erase/Program cycles.

To meet high-density, surface mount requirements, the SST39VF640xB devices are offered in 48-lead

TSOP and 48-ball TFBGA packages. See Figures and 2 for pin assignments.

Device Operation

Commands are used to initiate the memory operation functions of the device. Commands are written

to the device using standard microprocessor write sequences. A command is written by asserting WE#

low while keeping CE# low. The address bus is latched on the falling edge of WE# or CE#, whichever

occurs last. The data bus is latched on the rising edge of WE# or CE#, whichever occurs first.

The SST39VF640xB also have the Auto Low Power mode which puts the device in a near standby

mode after data has been accessed with a valid Read operation. This reduces the IDD active read cur-

rent from typically 9 mA to typically 3 µA. The Auto Low Power mode reduces the typical IDD active

read current to the range of 2 mA/MHz of Read cycle time. The device exits the Auto Low Power mode

with any address transition or control signal transition used to initiate another Read cycle, with no

access time penalty. Note that the device does not enter Auto-Low Power mode after power-up with

CE# held steadily low, until the first address transition or CE# is driven high.

Read

The Read operation of the SST39VF640xB is controlled by CE# and OE#, both have to be low for the

system to obtain data from the outputs. CE# is used for device selection. When CE# is high, the chip is

deselected and only standby power is consumed. OE# is the output control and is used to gate data

from the output pins. The data bus is in high impedance state when either CE# or OE# is high. Refer to

the Read cycle timing diagram for further details (Figure 3).

Word-Program Operation

The SST39VF640xB are programmed on a word-by-word basis. Before programming, the sector

where the word exists must be fully erased. The Program operation is accomplished in three steps.

The first step is the three-byte load sequence for Software Data Protection. The second step is to load

word address and word data. During the Word-Program operation, the addresses are latched on the

falling edge of either CE# or WE#, whichever occurs last. The data is latched on the rising edge of

either CE# or WE#, whichever occurs first. The third step is the internal Program operation which is ini-

tiated after the rising edge of the fourth WE# or CE#, whichever occurs first. The Program operation,

once initiated, will be completed within 10 µs. See Figures 4 and 5 for WE# and CE# controlled Pro-

gram operation timing diagrams and Figure 19 for flowcharts. During the Program operation, the only

valid reads are Data# Polling and Toggle Bit. During the internal Program operation, the host is free to

perform additional tasks. Any commands issued during the internal Program operation are ignored.

During the command sequence, WP# should be statically held high or low.

Sector/Block-Erase Operation

The Sector- (or Block-) Erase operation allows the system to erase the device on a sector-by-sector (or

block-by-block) basis. The SST39VF640xB offer both Sector-Erase and Block-Erase mode. The sector

architecture is based on uniform sector size of 2 KWord. The Block-Erase mode is based on uniform

block size of 32 KWord. The Sector-Erase operation is initiated by executing a six-byte command

sequence with Sector-Erase command (50H) and sector address (SA) in the last bus cycle. The Block-

Erase operation is initiated by executing a six-byte command sequence with Block-Erase command

(30H) and block address (BA) in the last bus cycle. The sector or block address is latched on the falling

edge of the sixth WE# pulse, while the command (50H or 30H) is latched on the rising edge of the sixth

WE# pulse. The internal Erase operation begins after the sixth WE# pulse. The End-of-Erase opera-

tion can be determined using either Data# Polling or Toggle Bit methods. See Figures 9 and 10 for tim-

ing waveforms and Figure 23 for the flowchart. Any commands issued during the Sector- or Block-

Erase operation are ignored. When WP# is low, any attempt to Sector- (Block-) Erase the protected

block will be ignored. During the command sequence, WP# should be statically held high or low.

Erase-Suspend/Erase-Resume Commands

The Erase-Suspend operation temporarily suspends a Sector- or Block-Erase operation thus allowing

data to be read from any memory location, or program data into any sector/block that is not suspended

for an Erase operation. The operation is executed by issuing one byte command sequence with Erase-

Suspend command (B0H). The device automatically enters read mode typically within 20 µs after the

Erase-Suspend command had been issued. Valid data can be read from any sector or block that is not

suspended from an Erase operation. Reading at address location within erase-suspended sectors/

blocks will output DQ2toggling and DQ6at “1”. While in Erase-Suspend mode, a Word-Program oper-

ation is allowed except for the sector or block selected for Erase-Suspend.

To resume Sector-Erase or Block-Erase operation which has been suspended the system must issue

Erase Resume command. The operation is executed by issuing one byte command sequence with

Erase Resume command (30H) at any address in the last Byte sequence.

Chip-Erase Operation

The SST39VF640xB provide a Chip-Erase operation, which allows the user to erase the entire mem-

ory array to the “1” state. This is useful when the entire device must be quickly erased.

The Chip-Erase operation is initiated by executing a six-byte command sequence with Chip-Erase

command (10H) at address 555H in the last byte sequence. The Erase operation begins with the rising

edge of the sixth WE# or CE#, whichever occurs first. During the Erase operation, the only valid read is

Toggle Bit or Data# Polling. See Table 6 for the command sequence, Figure 9 for timing diagram, and

Figure 23 for the flowchart. Any commands issued during the Chip-Erase operation are ignored. When

WP# is low, any attempt to Chip-Erase will be ignored. During the command sequence, WP# should

be statically held high or low.

Write Operation Status Detection

The SST39VF640xB provide two software means to detect the completion of a Write (Program or

Erase) cycle, in order to optimize the system write cycle time. The software detection includes two sta-

tus bits: Data# Polling (DQ7) and Toggle Bit (DQ6). The End-of-Write detection mode is enabled after

the rising edge of WE#, which initiates the internal Program or Erase operation.

The actual completion of the nonvolatile write is asynchronous with the system; therefore, either a

Data# Polling or Toggle Bit read may be simultaneous with the completion of the write cycle. If this

occurs, the system may possibly get an erroneous result, i.e., valid data may appear to conflict with

either DQ7or DQ6. In order to prevent spurious rejection, if an erroneous result occurs, the software

routine should include a loop to read the accessed location an additional two (2) times. If both reads

are valid, then the device has completed the Write cycle, otherwise the rejection is valid.

Data# Polling (DQ7)

When the SST39VF640xB are in the internal Program operation, any attempt to read DQ7will produce

the complement of the true data. Once the Program operation is completed, DQ7will produce true

data. Note that even though DQ7may have valid data immediately following the completion of an internal Write

operation, the remaining data outputs may still be invalid: valid data on the entire data bus will appear in subse-

quent successive Read cycles after an interval of 1 µs. During internal Erase operation, any attempt to read

DQ7will produce a ‘0’. Once the internal Erase operation is completed, DQ7will produce a ‘1’. The

Data# Polling is valid after the rising edge of fourth WE# (or CE#) pulse for Program operation. For

Sector-, Block- or Chip-Erase, the Data# Polling is valid after the rising edge of sixth WE# (or CE#)

pulse. See Figure 6 for Data# Polling timing diagram and Figure 20 for a flowchart.

Toggle Bits (DQ6 and DQ2)

During the internal Program or Erase operation, any consecutive attempts to read DQ6will produce

alternating “1”s and “0”s, i.e., toggling between 1 and 0. When the internal Program or Erase operation

is completed, the DQ6bit will stop toggling. The device is then ready for the next operation. For Sector-

, Block-, or Chip-Erase, the toggle bit (DQ6) is valid after the rising edge of sixth WE# (or CE#) pulse.

DQ6will be set to “1” if a Read operation is attempted on an Erase-Suspended Sector/Block. If Pro-

gram operation is initiated in a sector/block not selected in Erase-Suspend mode, DQ6will toggle.

An additional Toggle Bit is available on DQ2, which can be used in conjunction with DQ6to check

whether a particular sector is being actively erased or erase-suspended. Table 2 shows detailed status

bits information. The Toggle Bit (DQ2) is valid after the rising edge of the last WE# (or CE#) pulse of

Write operation. See Figure 7 for Toggle Bit timing diagram and Figure 20 for a flowchart.

Note: DQ7and DQ2require a valid address when reading status information.

Data Protection

The SST39VF640xB provide both hardware and software features to protect nonvolatile data from

inadvertent writes.

Hardware Data Protection

Noise/Glitch Protection: A WE# or CE# pulse of less than 5 ns will not initiate a write cycle.

VDD Power Up/Down Detection: The Write operation is inhibited when VDD is less than 1.5V.

Write Inhibit Mode: Forcing OE# low, CE# high, or WE# high will inhibit the Write operation. This pre-

vents inadvertent writes during power-up or power-down.

Hardware Block Protection

The SST39VF6402B support top hardware block protection, which protects the top 32 KWord block of

the device. The SST39VF6401B support bottom hardware block protection, which protects the bottom

32 KWord block of the device. The Boot Block address ranges are described in Table 3. Program and

Erase operations are prevented on the 32 KWord when WP# is low. If WP# is left floating, it is internally

held high via a pull-up resistor, and the Boot Block is unprotected, enabling Program and Erase opera-

tions on that block.

Hardware Reset (RST#)

The RST# pin provides a hardware method of resetting the device to read array data. When the RST#

pin is held low for at least TRP, any in-progress operation will terminate and return to Read mode. When

no internal Program/Erase operation is in progress, a minimum period of TRHR is required after RST#

is driven high before a valid Read can take place (see Figure 15).

The Erase or Program operation that has been interrupted needs to be reinitiated after the device

resumes normal operation mode to ensure data integrity.

Software Data Protection (SDP)

The SST39VF640xB provide the JEDEC approved Software Data Protection scheme for all data alter-

ation operations, i.e., Program and Erase. Any Program operation requires the inclusion of the three-

byte sequence. The three-byte load sequence is used to initiate the Program operation, providing opti-

mal protection from inadvertent Write operations, e.g., during the system power-up or power-down.

Any Erase operation requires the inclusion of six-byte sequence. These devices are shipped with the

Software Data Protection permanently enabled. See Table 6 for the specific software command codes.

During SDP command sequence, invalid commands will abort the device to read mode within TRC. The

contents of DQ15-DQ8can be VIL or VIH, but no other value, during any SDP command sequence.

Common Flash Memory Interface (CFI)

The SST39VF640xB also contain the CFI information to describe the characteristics of the device. In

order to enter the CFI Query mode, the system must write three-byte sequence, same as product ID

entry command with 98H (CFI Query command) to address 555H in the last byte sequence. Once the

device enters the CFI Query mode, the system can read CFI data at the addresses given in Tables 7

through 9. The system must write the CFI Exit command to return to Read mode from the CFI Query

mode.

Product Identification

The Product Identification mode identifies the devices as the SST39VF6401B and SST39VF6402B,

and the manufacturer as SST. This mode may be accessed through software operations. Users may

use the Software Product Identification operation to identify the part (i.e., using the device ID) when

using multiple manufacturers in the same socket. For details, see Table 6 for software operation, Figure

11 for the Software ID Entry and Read timing diagram and Figure 21 for the Software ID Entry com-

mand sequence flowchart.

Product Identification Mode Exit/CFI Mode Exit

In order to return to the standard Read mode, the Software Product Identification mode must be exited.

Exit is accomplished by issuing the Software ID Exit command sequence, which returns the device to

the Read mode. This command may also be used to reset the device to the Read mode after any inad-

vertent transient condition that apparently causes the device to behave abnormally, e.g., not read cor-

rectly. Please note that the Software ID Exit/CFI Exit command is ignored during an internal Program

or Erase operation. See Table 6 for software command codes, Figure 13 for timing waveform, and Fig-

ures 21 and 22 for flowcharts.

Security ID

The SST39VF640xB devices offer a 256-bit Security ID space. The Secure ID space is divided into two

128-bit segments - one factory programmed segment and one user programmed segment. The first

segment is programmed and locked at SST with a random 128-bit number. The user segment is left

un-programmed for the customer to program as desired.

To program the user segment of the Security ID, the user must use the Security ID Word-Program

command. To detect end-of-write for the SEC ID, read the toggle bits. Do not use Data# Polling. Once

this is complete, the Sec ID should be locked using the User Sec ID Program Lock-Out. This disables

any future corruption of this space. Note that regardless of whether or not the Sec ID is locked, neither

Sec ID segment can be erased.

The Secure ID space can be queried by executing a three-byte command sequence with Enter Sec ID

command (88H) at address 555H in the last byte sequence. To exit this mode, the Exit Sec ID com-

mand should be executed. Refer to Table 6 for more details.
