The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability pared with alternate approaches. The SST39WF400A writes (Program or Erase) with a 1.65-1.95V power supply. This device conforms to JEDEC standard pin assignments for x16 memories. Featuring high-performance Word-Program, the SST39WF400A device provides a typical Word-Program time of 28 µsec. The device uses Toggle Bit or Data# Polling to detect the pletion of the Program or Erase operation. To protect against inadvertent writes, it has on-chip hardware and software data protection schemes. Designed, manufactured, and tested for a wide spectrum of applications, this device is offered with a guaranteed typical endurance of 100,000 cycles. Data retention is rated at greater than 100 years. The SST39WF400A device is suited for applications that...
