This SRAM is designed for high-performance applications requiring fast access times and low power consumption.

Application Scenarios & Design Considerations

4 M SRAM (256-kword x 16-bit)

Alternative Part Number

  • IS61WV25616BLL-10TLI --: 256K x 16 asynchronous SRAM with similar 5V-tolerant I/O and pinout; widely available and often used as a drop-in replacement for Hitachi 256Kx16 SRAMs.
  • CY7C1041CV33-10ZXI --: 256K x 16 high-speed asynchronous SRAM with comparable access time and interface; a common cross-reference for Hitachi HM62 series parts.
  • AS6C4008-55TIN --: 512K x 8 low-power SRAM from a vendor that specializes in legacy SRAM replacements; can substitute where board layout allows byte-wide configuration or with minor adaptation.
