The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability pared with alternate approaches. The SST29SF020/040 devices write (Program or Erase) with a 4.5-5.5V power supply. The SST29VF020/040 devices write (Program or Erase) with a 2.7-3.6V power supply. These devices conform to JEDEC standard pin assignments for x8 memories. Featuring high performance Byte-Program, the SST29SF020/040 and SST29VF020/040 devices provide a maximum Byte-Program time of 20 µsec. To protect against inadvertent write, they have on-chip hardware and Software Data Protection schemes. Designed, manufactured, and tested for a...
