8 “PAL26V12” blocks with buried macrocells
Pin-compatible with MACH120 and MACH221
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.
