Application Scenarios & Design Considerations

In-System Programmable High Density PLD

Alternative Part Number

  • M4A5-64/32-7JC --: Lattice MACH4 CPLD in the same 44-pin PLCC package with comparable 64-macrocell logic capacity and 7.5 ns speed grade, a direct functional replacement for the ispLSI 1032E.
  • EPM7064SLC44-7 --: Altera MAX 7000S CPLD in 44-pin PLCC with 64 macrocells and 7 ns speed grade, widely used as a drop-in alternative to the ispLSI1032E in legacy designs.
  • XC9536XL-7PC44C --: Xilinx XC9500XL CPLD in 44-pin PLCC offering 36 macrocells and 7 ns pin-to-pin delay, suitable for lower-density replacements of the ispLSI1032E where full 32-macrocell logic is not required.
  • XC9536XL-7PC44 --: Xilinx XC9500XL CPLD in 44-pin PLCC offering in-system programmable 36-macrocell logic at 7 ns, a common lower-density alternative when full 32-macrocell capacity is not required.
  • M4A5-128/64-10VC --: Lattice's MACH4 CPLD family is the direct successor to ispLSI 1000E devices, offering comparable 128-macrocell density and 10 ns speed in a compatible PLCC package, making it the closest functional replacement.
  • EPM7128SLC84-10 --: Altera MAX 7000S CPLD with 128 macrocells and 10 ns pin-to-pin delay in an 84-pin PLCC, providing equivalent logic capacity and speed for legacy ispLSI 1032E designs.
  • XC95144XL-10TQG100C --: Xilinx XC9500XL CPLD with 144 macrocells and 10 ns speed grade, offering slightly higher logic density and 3.3V operation as a viable migration path when the original ispLSI 1032E is unavailable.
  • M4A5-128/64-7VC --: Lattice's own CPLD replacement family for the ispLSI 1032E, offering comparable macrocells and 5V operation with a different series name.
  • EPM7128SLC84-7 --: Widely available MAX 7000S CPLD with similar logic density and 5V operation, commonly used as a functional substitute for ispLSI 1032E designs.
  • XC95108-7PC84C --: XC9500 CPLD with comparable macrocell count and pin-compatible PLCC84 package option, suitable for legacy 5V CPLD replacement.
