32 Mbit Multi-Purpose Flash Plus SST39VF3201B / SST39VF3202B A Microchip Technology Company DataSheet Product Description The SST39VF320xB devices are 2M 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 alter- nate approaches. The SST39VF320xB write (Program or Erase) with a 2.7-3.6V power supply. ThesedevicesconformtoJEDECstandardpinassignmentsforx16memories. Featuring high performance Word-Program, the SST39VF320xB devices provide a typical Word- Program time of 7 µsec. These devices use Toggle Bit or Data# Polling to indicate the completion of Program operation. To protect against inadvertent write, they have on-chip hardware and Soft- ware Data Protection schemes. Designed, manufactured, and tested for a wide spectrum of appli- cations, these devices are offered with a guaranteed typical endurance of 100,000 cycles. Data retentionisratedatgreaterthan100years. The SST39VF320xB devices are suited for applications that require convenient and economical updating 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 during any Erase or Program operation is less than alternative flash tech- nologies. These devices also improve flexibility while lowering the cost for program, data, and con- figurationstorageapplications. 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- gramtimesincreasewithaccumulatedErase/Programcycles.

Word-Program Operation The SST39VF320xB 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. Thefirststepisthethree-byteloadsequenceforSoftwareDataProtection.Thesecondstepistoload 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 eitherCE#orWE#,whicheveroccursfirst.ThethirdstepistheinternalProgramoperationwhichisini- 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 Figure 6 and Figure 7 for WE# and CE# controlled Program operation timing diagrams and Figure 21 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.Duringthecommandsequence,WP#shouldbestaticallyheldhighorlow.

The operation is executed by issuing one byte command sequence with EraseResumecommand(30H)atanyaddressinthelastBytesequence. Chip-Erase Operation The SST39VF320xB provide a Chip-Erase operation, which allows the user to erase the entire mem- oryarraytothe“1”state.Thisisusefulwhentheentiredevicemustbequicklyerased.

Write Operation Status Detection The SST39VF320xB provide two software means to detect the completion of a Write (Program or Erase)cycle,inordertooptimizethesystemwritecycletime.Thesoftwaredetectionincludestwosta- tus bits: Data# Polling (DQ ) and Toggle Bit (DQ ). The End-of-Write detection mode is enabled after 7 6 therisingedgeofWE#,whichinitiatestheinternalProgramorEraseoperation. 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 DQ or DQ . In order to prevent spurious rejection, if an erroneous result occurs, the software 7 6 routine should include a loop to read the accessed location an additional two (2) times. If both reads arevalid,thenthedevicehascompletedtheWritecycle,otherwisetherejectionisvalid. ©2011SiliconStorageTechnology,Inc. DS25111A 12/11 6

Toggle Bits (DQ6 and DQ2) During the internal Program or Erase operation, any consecutive attempts to read DQ will produce 6 alternating“1”sand“0”s,i.e.,togglingbetween1and0.WhentheinternalProgramorEraseoperation iscompleted,theDQ bitwillstoptoggling.Thedeviceisthenreadyforthenextoperation.ForSector- 6 , Block-, or Chip-Erase, the toggle bit (DQ ) is valid after the rising edge of sixth WE# (or CE#) pulse. 6 DQ will be set to ‘1’ if a Read operation is attempted on an Erase-Suspended Sector/Block.

The systemcanalsoentertheCFIQuerymode,byusingtheone-bytesequencewith55HonAddressand 98H on Data Bus.
