SST29SF040-55-4C-NHE

SIC PLCC32 FLASH 512KX8 RoHS

PRODUCT DESCRIPTION

The SST29SF040 and SST29VF040 are 512K x8 CMOS Small-Sector Flash SSF manufactured with SST’s 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 SST29SF040 devices write Program or Erase with a 4.5-5.5V power supply. The SST29VF040 devices write Program or Erase with a 2.7-3.6V power supply. These devices conform to JEDEC standard pinouts for x8 memories.
