Application Scenarios & Design Considerations

In-System Programmable High Density PLD

Alternative Part Number

  • M4A3-32/32-10VC-12VI --: MACH4 CPLD in the same 32-macrocell class with 10 ns speed grade and 44-pin TQFP package, a direct functional replacement for the ispLSI2032.
  • EPM7032LC44-10 --: MAX 7000 CPLD with 32 macrocells, 10 ns speed, and 44-pin PLCC package; widely available second-source option for legacy 32-macrocell designs.
  • ATF1502AS-10JU44 --: High-performance 32-macrocell CPLD with 10 ns propagation delay in 44-pin PLCC, suitable as a pin-compatible-class alternative for the ispLSI2032.
  • M4A5-32/32-10VC --: M4A5 series is the pin-compatible upgrade path for ispLSI 2032 devices, offering 32 macrocells in a 44-pin TQFP with 10 ns speed, suitable when the M4A3 variant is unavailable.
