GENERAL DESCRIPTION

The MACH4-96/96 (M4-96/96) is a member of Vantis’ high-performance EE CMOS MACH 4 family. This device has approximately three times the macrocell capability of the popular MACH111SP, with significant additional density and functional features.

The M4-96/96 consists of six PAL? blocks interconnected by a programmable central switch matrix. The central switch matrix connects the PAL blocks to each other and to all input pins, providing a high degree of connectivity between the PAL blocks. This allows designs to be placed and routed efficiently. Routability is further enhanced by an input switch matrix and an output switch matrix. The input switch matrix provides input signals with alternative paths into the central switch matrix; the output switch matrix provides flexibility in assigning macrocells to I/O pins.
