PRODUCT DESCRIPTION
SST37VF512 device 128K 256K 512K CMOS, Many-Time Programmable (MTP), cost flash, manufactured with SST's proprietary, high performance CMOS SuperFlash technology. split-gate cell design thick-oxide tunneling injector attain better reliability manufacturability compared with alternate approaches. SST37VF512 electrically erased programmed least 1000 times using external programmer, e.g., change contents devices inventory. SST37VF512 erased prior programming. These devices conform JEDEC standard pinouts byte-wide flash memories. Featuring high performance Byte-Program, SST37VF512 provides typical Byte-Program time Designed, manufactured, tested wide spectrum applications, this device offered with endurance least 1000 cycles. Data retention rated greater than years. SST37VF512 suited applications that require infrequent writes power nonvolatile storage. This device will improve flexibility, efficiency, performance while matching cost nonvolatile applications that currently UV-EPROMs, OTPs, mask ROMs. meet surface mount conventional through hole requirements, SST37VF512 offered 32-lead PLCC, 32-lead TSOP 32-pin PDIP packages.

Device Operation
SST37VF512 device nonvolatile memory solutions that used instead standard flash devices in-system programmability required. functionally (Read) compatible with industry standard flash products.The device supports electrical Erase operation external programmer.
Read
Read operation SST37VF512 controlled OE#. Both have system obtain data from outputs. Once address stable, address access time equal delay from output (TCE). Data available output after delay from falling edge OE#, assuming been addresses have been stable least TCE-TOE. When high, chip deselected standby current only (typical) consumed. output control used gate data from output pins. data high impedance state when either VIH. Refer Figure timing diagram.
Byte-Program Operation
SST37VF512 programmed using external programmer. programming mode activated asserting 11.4-12V pin.

Kbit Many-Time Programmable Flash SST37VF512
Data Sheet device programmed using single pulse (WE# low) byte. Using programming algorithm, Byte-Program process continues byte-by-byte until entire chip been programmed. Refer Figure flowchart Figure timing diagram.
Product Identification Mode
Product Identification mode identifies device SST37VF512 manufacturer SST. This mode accessed hardware method. activate this mode, programming equipment must force (11.412V) address identifier bytes then sequenced from device outputs toggling address line details, Table hardware operation.

Chip-Erase Operation
only change data from electrical erase that changes every device "1". SST37VF512 uses electrical Chip-Erase operation. entire chip erased (WE# low). order activate erase mode, 11.4-12V applied pins while low. other address data pins "don't care". falling edge will start Chip-Erase operation. Once chip been erased, bytes must verified FFH. Refer Figure flowchart Figure timing diagram.

Design Considerations
SST37VF512 should have ceramic high frequency, inductance capacitor connected between GND. This capacitor should placed close package terminals possible. must remain stable entire duration Erase operation. must remain stable entire duration Program operation.
