The SST38VF6401/6402/6403/6404 are 4M x16 CMOS Advanced Multi-Purpose
Flash Plus (Advanced MPF+) devices manufactured with SST proprietary, high-
performance CMOS Super- Flash technology. The split-gate cell design and thick-
oxide tunneling injector attain better reliability and manufacturability compared
with alternate approaches. The SST38VF6401/6402/6403/6404 write (Program or
Erase) with a 2.7-3.6V power supply. This device conforms to JEDEC standard
pin assignments for x16 memories.
