Alternative Part Number

  • EPM7032LC44-15 --: CPLD in the same programmable logic class with comparable logic density and 44-pin PLCC package, suitable as a functional substitute for the PSD311 interface logic.
  • ATF1502AS-15JU44 --: Low-power CPLD with similar macrocell count and 5V-tolerant I/O, offering a different vendor and series as a drop-in style replacement for the PSD311V logic functions.
  • XC9536XL-10VQ44C --: Popular 3.3V CPLD with comparable logic capacity and 44-pin package, providing a well-supported alternative for the programmable logic portion of the original PSD device.
