Application Scenarios & Design Considerations

SILICON GATE CMOS 32,768 WORD x 8 BIT STATIC RAM

Alternative Part Number

  • IS62C256AL-45TLI --: 32K x 8 low-power CMOS SRAM with similar 28-pin TSOP package and 5V operation, widely used as a drop-in replacement for Toshiba 32K x 8 SRAMs.
  • AS6C62256-55SIN --: 32K x 8 low-power SRAM in a compatible TSOP package, direct functional equivalent with 5V supply and similar access time.
  • CY62256NLL-70ZXI --: 32K x 8 low-power SRAM with compatible pinout and 5V operation, a well-established alternative when 70ns access time is acceptable.
