Application Scenarios & Design Considerations

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

Alternative Part Number

  • AS6C4008-55TIN --: 512K x 8 low-power SRAM in TSOP with 55 ns access time, a direct functional replacement for the HM628512 series and widely available as an active part.
  • IS62WV5128EBLL-45TLI --: 512K x 8 low-power CMOS SRAM in TSOP-32 with 45 ns speed, pin-compatible with the HM628512BLTT and offering equal or better timing margin.
  • CY62158EV30LL-45ZSXI --: 512K x 8 low-power SRAM in TSOP-32 with 45 ns access time, a well-supported alternative with similar voltage and pinout to the original Hitachi part.
