Application Scenarios & Design Considerations

32 Mbit 4Mb x8, 2Mb x16, Uniform Block 3V Supply Flash Memory

Alternative Part Number

  • S29GL032N90TFI010 --: 32 Mbit parallel NOR flash in TSOP-56 with comparable organization and access time; widely available and pin-compatible in most designs.
  • MX29LV320EBTI-70G --: 32 Mbit 3V parallel NOR flash in TSOP-56, similar command set and timing, a common drop-in replacement for ST M58LW series.
  • AM29LV320DB-90EI --: Legacy 32 Mbit 3V NOR flash with compatible interface and package; suitable when sourcing older ST parts is difficult.
  • JS28F320J3D75A --: 32 Mbit parallel NOR flash in TSOP-56 with compatible address/data interface and 3V operation, a common drop-in replacement for ST 32 Mbit NOR parts.
  • S29GL032N90TFI040 --: 32 Mbit 3V page-mode NOR flash in TSOP-56 with similar command set and timing, widely used as an alternative to ST M58 series devices.
