Application Scenarios & Design Considerations

1 M SRAM (128-kword x 8-bit)

Alternative Part Number

  • IS61C1024AL-7TLI --: 128K x 8 asynchronous SRAM with 70 ns access time, pin-compatible with the HM628128 family and widely available from ISSI.
  • CY7C1021DV33-10ZSXI --: 128K x 8 low-power SRAM in the same JEDEC pinout, a common drop-in replacement when 70 ns timing is not critical.
  • AS6C1008-55TIN --: 128K x 8 low-power CMOS SRAM with 55 ns access time, pin-compatible and often used as a direct substitute for HM628128 devices.
