Application Scenarios & Design Considerations

4 M SRAM (512-kword x 8-bit)

Alternative Part Number

  • AS6C4008-55PCN --: Alliance Memory specializes in SRAM drop-in replacements for legacy Hitachi parts; 512Kx8 5V SRAM with 55ns access, functionally equivalent to the HM628512 series.
  • CY7C1041CV33-10ZXC --: Widely available 512Kx8 asynchronous SRAM with comparable speed grade and pinout, a common substitute for Hitachi 628512 devices.
  • IS61WV5128BLL-10TLI --: ISSI 512Kx8 low-power SRAM with similar organization and timing; a well-stocked alternative when Hitachi parts are obsolete.
