PRODUCT DESCRIPTION
The SST39VF168x devices are 2M x8 C MOS 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 SST39VF168x write (Pro­gram or Erase) with a 2.7-3.6V power supply. These devices conform to JEDEC standard pinouts for x8 mem­ories.
Featuring high performance Byte-Program, the SST39VF168x devices provide a typical Byte-Program time of 7 µsec. These devices use T oggle Bit or Data# Poll­ing to indicate the completion of Program operation. To pro­tect against inadvertent write, they have on-chip hardware and Software Data Protec tion schem es. Designed, manu­factured, and tested for a wide spectrum of applications, these devices are offered with a g ua rant eed ty pic al en dur ­ance of 100,00 0 cycles. Data retention is ra ted at greater than 100 y ears .
The SST39VF168x devices are suited for applications that require convenient and economi cal updating of program, configuration, or da ta memory. For all system a ppl i ca tio ns,
they significantly i mp r ove performa nc e an d re li ab il it y, while lowering power consumption. They inherently use less energy during Erase and Program than alternative flash technologies. The tota l energy consumed is a function of the applied voltage, curre nt, and time of ap plic ation . Sinc e for any given voltage 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 technologies. These devices also impr ove flexibility while lowering the c ost for program, data, and configuration storage applications.
The SuperFlash technology prov ides fixed Erase and Pro­gram times, independent of the n umbe r of Er ase/Prog r am cycles that have occurred. Therefore the system software or hardware does not hav e to be modified or de-rated as is necessary with alternative flash technologies, whose Erase and Program times increase with accumulated Erase/Program cycles.
To meet high density, surface mount requirements, the SST39VF168x are offered in both 48-ball TFBGA and 48-lead TSOP packages. See Figures 1 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 microprocess or write sequences. A com­mand is written by asse r ting WE# low whil e keeping CE# low. The address bus is latched on the falling edge of WE# or CE#, whichever occurs last. T he data bus is latc hed o n the rising edge of WE# or CE#, whichever occurs first.
The SST39VF168x 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 I typically 3 µA. The Auto Low Pow er mode reduces the typi­cal I
active read current to the range of 2 mA/MHz of
DD
Read cycle time. The device exits the Auto Low Power mode with any address transition or control signal transition used to initiate ano ther Read cycle, with no access t ime 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.
active read current from typically 9 mA to
DD
Read
The Read operation of the SST39VF168x 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).
Byte-Program Operation
The SST39VF168x are programmed on a byte-by-byte basis. Before programming, the sector where the byte 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 s econd step is to load byte address and byte data. During the Byte­Program opera tion, th e addr esses ar e latche d on the fa lling edge of either CE# or WE#, whichever occurs last. The data is latched on th e rising edge of ei ther CE# or WE#, whichever occurs first. The third step is the in ternal Pro­gram operation which is initiated 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 Figure s 4 a nd 5 for WE # and CE # co nt ro ll ed P r og ram operation timing diagrams and Figure 19 for flowcharts. During the Program operation, the only valid reads are Data# Polling and Toggle Bit. During the in tern al Program operation, the host is fre e to perform ad ditiona l tasks. Any
commands issu ed during the inter nal Program operation are ignored. Dur ing the c omman d seq uence, WP # sho uld be statically held high or lo w .
Sector/Block-Erase Operation
The Sector- (or Block-) Erase operation allows the system to erase the device on a sector-by-sector (or block-by­block) basis. The SST39V F168x offer both Sector-Erase and Block-Erase mode. The sec tor architecture is based on uniform sector size of 4 KByte. The Block-Erase mode is based on unifor m block size of 64 KByte. The Sector­Erase 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 comm and (30H or 50H) is latched on th e rising edge of the sixth WE# pulse. The internal Erase operation begins a fter the sixth WE# pulse. The End -of­Erase operation can be determined using either Data# Polling or Toggle Bit methods. See Figures 9 and 10 for tim­ing waveforms and Figure 23 for the flowchart. Any com­mands issued during the Sec tor- or B lock-Era se op erat io n are ignored. When WP# is low, any attempt to Sector­(Block-) Erase the prote cted block will be ignor ed. 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 memor y loca tion, or program data into any sector/block that is not sus pended 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 Era se-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 addr ess location withi n erase-suspende d sectors/blocks will output DQ
toggling and DQ6 at “1”. While in Erase-Suspend
2
mode, a Byte-Program operation is allowed except for the sector or block selected for Erase-Suspend.
T o 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 th e last Byte sequence .

Preliminary Specifications
Chip-Erase Operation
The SST39VF168x provide a Chip-Erase o peration, w hich allows the user to erase the entire memory arra y to the “1” state. This is useful when the entire de vice must be quickly erased.
The Chip-Erase operation is initiated by executing a six­byte command sequence with Chip-Erase command (10H) at address AAAH 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 v alid read is Toggle Bit or Data# P olling. 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 lo w.
Write Operation Status Detection
The SST39VF16 8x provide two softwar e means to det ect the completion of a Write (Program or Erase) cycle, in order to optimize the syst em write cycl e time . The s oftw are detection includes two status bits: Data# Polling (DQ Toggle Bit (DQ
). The End-of-Write detection mode is
6
) and
7
enabled after the rising edge of WE#, which initiate s 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 w it h ei th er D Q
or DQ6. In order to pre-
7
vent 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 reje ction is valid.
Data# Polling (DQ7)
When the SST39VF168x are in the internal Program ope r­ation, any attempt to read DQ ment of the true data. Once the Program operation is completed, DQ though DQ
will produce true data. Note that even
7
may have valid data immediately following the
7
completion of an internal Write operation, the remaining data outputs may still be invalid: valid data on the entire data bus will appear in subsequent successive Read cycles after a n in te rva l of 1 µ s . Du ring internal Erase oper­ation, any attempt t o rea d DQ internal Erase operation is completed, DQ
will produce the comple-
7
will produce a ‘0’. Once the
7
will produce a
7
‘1’. The Data# P olling is v alid after the rising edge o f f ourth 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# P olling timing diagram an d Figure 20 f or a flowchart.
Toggle Bits (DQ6 and DQ2)
During the inter nal Program or Erase ope ration, any con­secutive attempts to read DQ and “0”s, i.e., toggling between 1 and 0. Wh en the i nte rnal Program or Erase operat ion is complete d, the DQ stop toggling. The device is then ready for the next opera­tion. For Sector-, Block-, or Chip-Erase, the toggle bit (DQ is valid after the ris ing edge of six th WE# (or CE#) p ulse. DQ
will be set to “1” if a Read operation is attempted on an
6
Erase-Suspended Sector/Block. If Program operation is ini­tiated in a sector/block not selected in Erase-Suspend mode, DQ
will toggle .

An additional Toggle Bit is available on DQ used in conjunction with DQ sector is being actively erased or erase-suspended. T able 1 shows detailed status bits information. The Toggle Bit (DQ
) 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.

Data Protection
The SST39VF168x provide both hardware and software feature s to pr otect n onv ol atile data f rom inad vertent writ es.
Hardware Data Protection
Noise/Glitch Protection: A WE# or CE# pulse of le ss than 5 ns will not init iate a write cycle .
V
Power Up/Down Detection: The Write operation is
DD
inhibited when V Write Inhibit Mode:
is less than 1.5V.
DD
Forcing OE# low, CE# high, or WE# high will inhibit the W r ite operation. This prevents inadvert­ent writes during p ow er-up o r po wer- down.
Hardware Block Protection
The SST39VF168 2 supports top har dware block protec­tion, which protects the top 64 KByte block of the device. The SST39VF1681 su pports bottom hardware block pro­tection, which pr otects the bottom 64 KByte block of the device. The Boot Block addre ss ranges are describ ed in Table 2. Program and Erase operation s are prevented on the 64 KByte 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 opera­tions 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 T
any in-progress operation will terminate and
RP,
return to Read mode. When no internal Program/Erase operation is in progress, a minimum period of T
RHR
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 SST39VF 168x pr ovide t he JEDEC appro ved S oftw are Data Protection schem e for all data alteration operations, i.e., Program and Erase. Any Program operation requi res the inclusion of the th ree-byte sequence. The three-byte load sequence is used to initiate the Program operation, providing optimal pr otection from inad vertent W rite opera­tions, e.g., during the system power-up or power-down. Any Erase operation requires the inclusion of six-byte sequence. These devices a re 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 T
RC.
Common Flash Memory Interface (CFI)
The SST39VF168x 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 AAAH in the last byte sequence. Once the device enters the CFI Query mode, the system can read CFI data at the addresses given in Tab les 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 Identificatio n mode id entifies th e devices as the SST39VF1681 and SST39VF1682, and manufacturer as SST. Users may use the s oftware Product Identifica­tion operation to identify the part (i.e., using the device ID) when using multiple manufacturers in the same s ocket. 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 c ommand sequence flowchart.

Product Identification Mode Exit/ CFI Mode Exit
In order to return to the standard Read mode, the Software Product Identific ation mode must be exited. Exit is acco m­plished 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 inadvertent transient condition that
apparently caus es the device to behave abnor mally, e.g., not read correctly. 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 Figures 21 and 22 for flowcharts.
Security ID
The SST39VF168x devices offer a 256-bit Security ID space which is divided into two 128-bit segments. The first segment is programmed and locked at SST with a random 128-bit number. The user segment is left un-programme d for the customer to prog ram a s desir ed.
To program the user segm ent of the Security ID, the user must use the Security ID Byte-Program command. To detect end-of-write for the SEC ID, read the toggle bits. Do not use Data# Polling. Once this is complet e, the Sec ID should be locked using the User Sec ID Program Lock-Out. This disables any future corr up ti on of this sp ac e. Note tha t regardless of whether or not the Sec ID is locked, neither Sec ID segment can be erased.
The Security ID space can be queried by executing a three-byte command sequence with Enter-Sec-ID com­mand (88H) at addr ess AAAH in the last byte s equence. Execute the Exit-Sec-ID command to exit this mode. Refer to Table 6 for more details.
