Application Scenarios & Design Considerations

4M (512K X 8/256K X 16) BIT

Alternative Part Number

  • SST39VF400A-70-4C-EKE --: 4 Mbit (512K x 8) 3V NOR flash in TSOP-48, same density and organization as the original, widely available and pin-compatible in most designs.
  • AM29LV400B-70EI --: 4 Mbit 3V boot-sector NOR flash with compatible command set and TSOP-48 footprint, a direct functional replacement for the Fuji device.
  • MX29LV400CTTI-70G --: 4 Mbit 3V parallel NOR flash in TSOP-48 with standard JEDEC command set, offering a cost-effective drop-in alternative.
  • S29GL032N90TFI040 --: 3V 32Mb parallel NOR flash in TSOP-48, a direct functional replacement for the 4Mb device with a different series name.
