- 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 SST39SF010A 4 seconds (typical) for SST39SF020A 8 seconds (typical) for SST39SF040
- End-of-Write Detection – Toggle Bit – Data# Polling
