GENERAL DESCRIPTION
The MACH110 is a member of our high-performance
EE CMOS MACH 1 family. This device has approxi-
mately three times the logic macrocell capability of the
popular PAL22V10 without loss of speed.
The MACH110 consists of two PAL blocks intercon-
nected by a programmable switch matrix. The two PAL
blocks are essentially “PAL22V16” structures complete
with product-term arrays and programmable macro-
cells. 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.
