Application Scenarios & Design Considerations

256 KBIT (32K X8) 3.0V ASYNCHRONOUS SRAM

Alternative Part Number

  • AS6C62256-55SIN --: 32K x 8 low-power SRAM with comparable 55 ns access time, widely used as a drop-in replacement for legacy ST SRAM parts.
  • CY62256NLL-70SNXI --: 32K x 8 asynchronous SRAM in a similar SOIC package with 70 ns speed, a common second-source option for legacy SRAM designs.
  • IS62WV256-70T --: 32K x 8 low-power CMOS SRAM with 70 ns access time, suitable as a functional substitute when slightly slower timing is acceptable.
  • CY62128EV30LL-45ZXI --: 128K x 8 low-power SRAM in TSOP-32, functionally equivalent to the 256Kbit async SRAM with similar access speed and pinout; widely available and well documented.
  • IS62WV1288DBLL-45TLI --: 128K x 8 low-power CMOS SRAM with 45ns access time in TSOP-32, drop-in compatible for most M68AW031AM socket designs and readily stocked.
  • AS6C1008-55TIN --: 128K x 8 low-power SRAM in TSOP-32 with 55ns access, a common legacy-compatible replacement for STM async SRAM parts; slightly slower but electrically compatible.
