Product Highlight

  • Memory Density: 4 Mb
  • Memory Organization: 512 K x 8
  • Supply Voltage-Nom: 2.7 to 3.6 V
  • Access Time-Max: 70 ns
The SST39VF040-70-4I-NHE-T is a 4 Mbit multi-purpose flash memory device. It is available in 32 pin PLCC package.

This device is manufactured with SST 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.
