Application Scenarios & Design Considerations

262, 144-WORD BY 16-BIT CMOS STATIC RAM

Alternative Part Number

  • IS61LV25616AL-15TLI --: 256K x 16 asynchronous SRAM with 15 ns access time in a TSOP package, functionally equivalent to the original 256K x 16 SRAM and widely available.
  • CY7C1041CV33-15ZXI --: 256K x 16 low-power SRAM with 15 ns speed grade, same organization and comparable supply voltage, suitable as a direct drop-in alternative.
  • AS6C4008-55TIN --: 512K x 8 low-power CMOS SRAM in TSOP; can replace the original in many designs with adjusted addressing, and Alliance specializes in legacy SRAM replacements.
