Application Scenarios & Design Considerations

4 MBIT (256K X16) 3.0V ASYNCHRONOUS SRAM

Alternative Part Number

  • CY7C1021DV33-10ZSXI --: 256K x 16 asynchronous SRAM with 3.3V supply and similar 70-10ns speed grade, pin-compatible 44-pin TSOP package, widely available replacement for the M68AW256.
  • IS61WV25616EDBLL-10TLI --: 256K x 16 high-speed asynchronous SRAM in 44-pin TSOP II, 3.3V, 10ns access time, direct functional equivalent with industrial temperature range.
  • AS6C25616-55TIN --: 256K x 16 low-power CMOS SRAM, 44-pin TSOP II, 3.3V, drop-in compatible timing and pinout, good second-source option for legacy ST SRAM designs.
