Alternative Part Number

  • S29GL032N90TFI010 --: Pin-compatible 3V parallel NOR flash from the Spansion/Cypress GL family, which is the direct successor line to Fujitsu's LV series; 90 ns speed grade matches the original timing.
  • MX29LV400CTTI-90G --: 4 Mbit 3V bottom-boot parallel NOR flash with the same 90 ns access time and TSOP-48 pinout, widely used as a drop-in replacement for Fujitsu LV400 devices.
  • AM29LV400BT-90EI --: Original industry-standard 4 Mbit 3V NOR flash that the Fujitsu MBM29LV400 was designed to be compatible with; same command set, 90 ns speed, and TSOP-48 footprint.
  • SST39VF400A-70-4C-EKE --: 4 Mbit 3V parallel NOR flash in TSOP-48 with compatible pinout and command set, faster 70 ns access, widely available and drop-in for most designs.
  • AM29LV400B-90EI --: Same 4 Mbit 3V boot-sector flash family lineage as the original Fujitsu part, 90 ns speed, TSOP-48 package, direct functional equivalent with mature supply.
  • MX29LV400CTTI-70G --: 4 Mbit 3V parallel NOR flash, TSOP-48, 70 ns, compatible command interface and pinout, cost-effective second source for legacy 29LV400 designs.
  • S29GL032N90TFI040 --: Spansion/Cypress 3V parallel NOR flash in the same 48-pin TSOP package with comparable 90 ns access time; Spansion is the successor to Fujitsu's flash line, so timing and interface are closely compatible.
