Alternative Part Number

  • M27C256B-90F1 --: 256Kbit EPROM in a comparable PLCC/DIP package with 90 ns access time, suitable as a functional substitute for the ZPSD303 configuration memory role.
  • AT28C256-90JU --: 256Kbit parallel EEPROM with 90 ns speed grade and PLCC package, offering similar non-volatile memory capacity and timing for legacy designs.
  • AM29F010B-90JC --: 1Mbit flash memory with 90 ns access time in PLCC, providing a higher-density non-volatile alternative compatible with the original 90 ns timing class.
  • W78E516B-40PL --: 8051-compatible microcontroller with integrated flash and configurable logic, similar to the PSD3xx configurable system peripheral role; widely available and pin-compatible in PLCC packages.
  • AT89C51RC2-3CSUM --: 8051-based MCU with on-chip flash and flexible I/O, suitable replacement for designs using the PSD303 configurable memory/peripheral device.
  • EPM7032LC44-15 --: CPLD in PLCC44 package offering programmable logic similar to the PSD303's configurable logic block, useful when only the logic portion is required.
