Application Scenarios & Design Considerations

4 Mbit (512K x 8/256K x 16) Low Voltage Flash Memory

Alternative Part Number

  • SST39VF400A-70-4C-EKE --: 4 Mbit (256K x16) 3V parallel NOR flash in TSOP-48, functionally equivalent to the HY29LV400T with compatible command set and pinout.
  • MX29LV400CTTC-55Q --: 4 Mbit 3V bottom-boot parallel NOR flash with 55 ns access time, direct drop-in replacement for the HY29LV400TT-55 in TSOP-48.
  • AM29LV400BT-70EI --: Industry-standard 4 Mbit 3V NOR flash, same x16 organization and TSOP-48 footprint; widely available second source for legacy Hynix LV400 designs.
  • AM29LV400BT-55EI --: Industry-standard 4 Mbit 3V NOR flash, 55 ns, TSOP-48 package, functionally equivalent and broadly second-sourced for HY29LV400 designs.
