Application Scenarios & Design Considerations

32 Mbit 4Mb x8 or 2Mb x16, Dual Bank 8:24, Boot Block 3V Supply Flash Memory

Alternative Part Number

  • S29GL032N90TFI040 --: 32 Mbit parallel NOR flash in TSOP-48 with similar 3 V interface and access timing, widely available and pin-compatible in most designs.
  • MX29LV320EBTI-70G --: 32 Mbit 3 V parallel NOR flash in TSOP-48 with 70 ns speed grade, a common drop-in replacement for ST M29DW series.
  • AM29LV320DB-90EI --: 32 Mbit 3 V boot-sector NOR flash in TSOP-48, same legacy AMD/ST command set family, suitable when 90 ns timing is acceptable.
