Application Scenarios & Design Considerations

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

Alternative Part Number

  • S29GL032N90TFI010 --: 32 Mbit parallel NOR flash in TSOP-48 with 90 ns access time, functionally equivalent to the M28W320CB and widely available.
  • MX29LV320EBTI-90G --: 32 Mbit 3V parallel NOR flash, 90 ns speed grade, TSOP-48 package, pin-compatible replacement for the M28W320CB-90N6.
  • SST39VF3201B-70-4I-EKE --: 32 Mbit parallel NOR flash in TSOP-48 with similar interface; faster 70 ns grade can substitute for the 90 ns part in most designs.
  • AM29LV320DB-90EI --: 32 Mbit 3V parallel NOR flash in the same TSOP-48 package with comparable 90 ns access time, a widely used drop-in class replacement for the M28W320CB.
  • S29GL032N90TFI040 --: 32 Mbit 3V page-mode NOR flash, 90 ns speed grade, TSOP-48 footprint, well-established second source with similar command-set compatibility.
