Application Scenarios & Design Considerations

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

Alternative Part Number

  • IS61C5128AL-10TLI --: 512K x 8 asynchronous SRAM with similar access time and pinout, widely available and commonly used as a drop-in replacement for Hitachi 512Kx8 SRAMs.
  • CY7C1041CV33-10ZXI --: 512K x 8 low-power SRAM in TSOP package with comparable speed grade, suitable functional replacement for the HM628512 series.
  • AS6C4008-55PIN --: 512K x 8 low-power CMOS SRAM designed as a direct replacement for legacy Hitachi SRAM parts, with similar timing and package options.
