Application Scenarios & Design Considerations

32 MBIT (2MB X16, UNIFORM BLOCK, BURST)3V SUPPLY FLASH MEMORY

Alternative Part Number

  • AM29LV320DB-90EI --: 32 Mbit parallel NOR flash with 90 ns access time, same x16 organization and TSOP package, widely used as a drop-in replacement for ST M58LW series.
  • S29GL032N90TFI010 --: 32 Mbit 3V page-mode NOR flash with 90 ns speed, compatible command set and pinout, good second-source option for the M58LW032C.
  • MX29LV320EBTI-90G --: 32 Mbit low-voltage parallel NOR flash, 90 ns, x16 interface in TSOP-48, cost-effective alternative with similar read/write timing.
