Description

The SST29SF04055-4C-NH is a CMOS Small-Sector Flash (SSF) electronic component manufactured with SST's proprietary SuperFlash technology. It is available in different configurations including 64K x8, 128K x8, 256K x8, and 512K x8. The split-gate cell design and thick oxide tunneling injector make it highly reliable and manufacturable. This component operates with a 4.5-5.5V power supply for writing (Program or Erase) and conforms to JEDEC standard pinouts for x8 memories.
