Application Scenarios & Design Considerations

256 Kbit (32Kb X8) ZEROPOWER SRAM

Alternative Part Number

  • DS1230AB-100+ --: Nonvolatile SRAM module with 256Kbit capacity and 100ns access time, functionally equivalent to the M48Z35AV and widely used as a drop-in replacement in battery-backed SRAM sockets.
  • BQ4011YMA-100 --: Battery-backed nonvolatile SRAM in a similar DIP module footprint with comparable capacity and timing, suitable for direct substitution in legacy designs.
  • CY14B256L-SZ45XC --: 256Kbit nonvolatile SRAM with integrated battery/backup, offering similar organization and access timing for replacement of the M48Z35AV in existing boards.
