GENERAL DESCRIPTION

The MACH220 is a member of AMD’s high-performance

EE CMOS MACH 2 device family. This device has

approximately nine times the logic macrocell capability

of the popular PAL22V10 without loss of speed.

The MACH220 consists of eight PAL blocks intercon-

nected by a programmable switch matrix. The eight PAL

blocks are essentially “PAL26V12” structures complete

with product-term arrays, and programmable macro-

cells, including buried 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 MACH220 has two kinds of macrocell: output and

buried. The output macrocell provides registered,

latched, 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 output 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.

The MACH220 has dedicated buried macrocells which,

in addition to the capabilities of the output macrocell,

also provide input registers for use in synchronizing

signals and reducing setup time requirements.
