Application Scenarios & Design Considerations

32MBIT (2MB X 16, BOOT BLOCK) 3V SUPPLY FLASH MEMORY

Alternative Part Number

  • S29GL032N90TFI040 --: 32 Mbit parallel NOR flash in TSOP-48 with comparable 90 ns access time and same 3 V supply, a common drop-in replacement for the M28W320 series.
  • MX29GL320EHT2I-70G --: 32 Mbit 3 V parallel NOR flash in TSOP-48 with 70 ns speed, pin-compatible with the M28W320EC and widely available as a second source.
  • SST39VF3201B-70-4I-EKE --: 32 Mbit 3 V parallel NOR flash in TSOP-48 with 70 ns access, functionally equivalent and a good fallback when Cypress or Macronix parts are unavailable.
