Microchip 4Mbit Flash Memory 32-Pin TSOP, SST39SF040-70-4C-WHE

The Microchip CMOS multi purpose flash (MPF) manufactured with SST proprietary, high performance CMOS Super flash technology. The split-gate cell design and thick oxide tunnelling injector attain better reliability and manufacturability compared with alternate approaches. The SST39SF040 writes (Program or Erase) with a 4.5-5.5V power supply, and conforms to JEDEC standard pinouts for x8 memories.

Superior reliability- 100000 cycles endurance (typical)
Greater than 100 years data retention
TTL I/O Compatibility
Low power consumption
Sector-Erase Capability – Uniform 4 Kbyte sectors
RoHS compliant
