Application Scenarios & Design Considerations

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

Alternative Part Number

  • IS62C256AL-45ULI --: 32K x 8 low-power CMOS SRAM with similar asynchronous interface and 5V-compatible operation; widely available and pin-compatible in the same TSOP/SOP footprint.
  • AS6C62256-55SIN --: 32K x 8 low-power SRAM functionally equivalent to the TC55257B series, with comparable access time and pinout, suitable as a direct drop-in replacement.
  • CY62256NLL-70SNXI --: 32K x 8 low-power SRAM with similar organization and interface; slightly slower access time but electrically compatible for most non-timing-critical designs.
