Application Scenarios & Design Considerations

3.3V High Density Programmable Logic

Alternative Part Number

  • M4A5-128/64-10YC-12YI --: Lattice MACH4 CPLD family is the direct successor to ispLSI 2128V, offering comparable 128-macrocell density and 5V/3.3V operation in a TQFP-176 package.
  • EPM7128SLC84-10 --: Altera MAX7000S CPLD with 128 macrocells provides similar logic capacity and is a widely available drop-in class alternative for legacy ispLSI designs.
  • XC95144XL-10TQG144 --: Xilinx XC9500XL CPLD offers 144 macrocells of comparable programmable logic and is a common replacement when migrating from ispLSI 2128V devices.
  • XC95144XL-10TQG144C --: Xilinx XC9500XL CPLD with 144 macrocells, offering comparable density and 3.3V operation for legacy ispLSI 2128V replacements.
