This SDRAM is designed for high-speed memory applications requiring efficient data transfer.

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, same 44-pin TSOP package and 3.3 V supply, widely available and pin-compatible replacement.
  • CY7C1021DV33-15ZSXI --: 64K x 16 high-speed CMOS SRAM with 15 ns speed grade, 3.3 V operation and TSOP II footprint matching the original device.
  • AS6C62256-55SIN --: Low-power 32K x 8 SRAM in a similar TSOP package; suitable when reduced density is acceptable and a long-life legacy SRAM source is needed.
