PRODUCT DESCRIPTION
The SST39WF400A device is a 256K x16 CMOS MultiPurpose Flash (MPF) 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 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 completion 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 enduran...
