ispMACH™ 4A CPLD Family is a high-performance E2CMOS® In-System Programmable Logic released by Infineon, with features of high performance, high speed, flexible architecture and advanced capabilities.
The ispMACH 4A family from Lattice offers a flexible E°CMOS architecture with densities from 32 to 512 macrocells and pin counts from 44 to 388. Both 3.3‑V and 5‑V operation are supported, and devices are JTAG (IEEE 1149.1) and PCI compliant for in‑system programming and boundary‑scan testing.
The handbook details device features, speed grades, package options (PLCC, PQFP, TQFP, BGA, fpBGA, caBGA), and the internal architecture, including the central switch matrix, PAL blocks, product‑term array, and logic allocator. Tables list macrocell counts, I/O options, power consumption, and valid commercial/industrial speed combinations.

The ispMACH 4A devices operate at either 3.3 V or 5 V.
Commercial‑grade devices achieve a 5.0 ns tpp timing and up to 182 MHz operation.
In‑system programming is performed via a JTAG (IEEE 1149.1) interface.
The family is offered in PLCC, PQFP, TQFP, BGA, fine‑pitch BGA (fpBGA) and chip‑array BGA (caBGA) packages ranging from 44 to 388 pins.
