Microchip Technology, Inc. 2Mb 4.5-5.5V Parallel Flash SST39SF020A

The SST39SF020A is a CMOS Multi-Purpose Flash (MPF) manufactured with SST 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 SST39SF020A writes (Program or Erase) with a 4.5-5.5V power supply, and conforms to JEDEC standard pinouts for x8 memories. Additional Features Organized as 128K x8 / 256K x8 / 512K x8 Single 4.5-5.5V Read and Write Operations Superior Reliability– Endurance: 100,000 Cycles (typical)– Greater than 100 years Data Retention Low Power Consumption(typical values at 14 MHz)– Active Current: 10 mA (typical)– Standby Current: 30 µA (typical) Sector-Erase Capability– Uniform 4 KByte sectors Fast Read Access Time:– 55 ns– 70 ns Latched Address and Data Automatic Write Timing– Internal VPP Generation Fast Erase and Byte-Program– Sector-Erase Time: 18 ms (typical)– Chip-Erase Time: 70 ms (typical)– Byte-Program Time: 14 µs (typical)– Chip Rewrite Time:2 seconds (typical) for SST39SF010A4 seconds (typical) for SST39SF020A8 seconds (typical) for SST39SF040 End-of-Write Detection– Toggle Bit– Data# Polling TTL I/O Compatibility JEDEC Standard– Flash EEPROM Pinouts and command sets Packages Available– 32-lead PLCC– 32-lead TSOP (8mm x 14mm)– 32-pin PDIP All devices are RoHS compliant All non-Pb (lead-free) devices are RoHS compliant
