Microchip 4Mbit SPI Flash Memory 32-Pin TSOP, SST39LF040-55-4C-WHE

The Microchip 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 SST39LF040 device writes (Program or Erase) with a 3.0-3.6V power supply. The device conforms to JEDEC standard pinouts for x8 memories.

Superior reliability- 100000 cycles endurance (typical)
Greater than 100 years data retention
Low power consumption
Sector erase capability– Uniform 4 Kbyte sectors
CMOS I/O compatibility
RoHS compliant
