MACH110-20

The MACH110 is a member of AMD's high-performance EE CMOS MACH 1 family. This device has approximately three times the logic macrocell capability of the popular PAL22V10 without loss of speed.

The MACH110 consists of two PAL blocks interconnected by a programmable switch matrix. The two PAL blocks are essentially "PAL22V16" structures complete with product-term arrays and programmable macrocells. The switch matrix connects the PAL blocks to each other and to all input pins, providing a high degree of connectivity between the fully-connected PAL blocks. This allows designs to be placed and routed efficiently.

The MACH110 macrocell provides either registered or combinatorial outputs with programmable polarity. If a registered configuration is chosen, the register can be configured as D-type or T-type to help reduce the number of product terms. The register type decision can be made by the designer or by the software. All macrocells can be connected to an I/O cell. If a buried macrocell is desired, the internal feedback path from the macrocell can be used, which frees up the I/O pin for use as an input.
