Alternative Part Number

  • IS61C256AL-70T --: 32K x 8 asynchronous SRAM with 70 ns access time, functionally equivalent to the M5M5256 series and widely available.
  • CY62256NLL-70PXC --: 32K x 8 low-power SRAM with 70 ns speed, pin-compatible with standard 28-pin DIP SRAMs and a common drop-in replacement.
  • AS6C2568-55PCN --: 32K x 8 low-power CMOS SRAM in 28-pin DIP, 55 ns speed meets the 70 ns requirement and is a direct functional substitute.
