Application Scenarios & Design Considerations

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

Alternative Part Number

  • S29GL032N90TFI040 --: Spansion/Cypress 3V parallel NOR flash in the same 48-pin TSOP package; a direct functional replacement for the Fujitsu 4Mbit device with compatible command set and pinout.
  • AM29LV400BT-70EI --: AMD/Spansion 4Mbit 3V boot-sector NOR flash with the same JEDEC command interface and TSOP-48 footprint, widely used as a drop-in substitute for Fujitsu MBM29LV series.
  • MX29LV400CTTI-70G --: Macronix 4Mbit 3V parallel NOR flash, pin-compatible TSOP-48 device with equivalent read access time and JEDEC-standard commands, offering a cost-effective second source.
