GENERAL DESCRIPTION
The MACH230 is a member of the high-performance
EE CMOS MACH 2 device family. This device has ap-
proximately twelve times the logic macrocell capability
of the popular PAL22V10 without loss of speed.
The MACH230 consists of eight PAL blocks intercon-
nected by a programmable switch matrix. The switch
matrix connects the PAL blocks to each other and to all
input pins, providing a high degree of connectivity be-
tween the fully-connected PAL blocks. This allows
designs to be placed and routed efficiently.
The MACH230 has two kinds of macrocell: output and
buried. The output macrocell provides registered,

MACH231, and MACH435
latched, or combinatorial outputs with programmable
polarity. If a registered configuration is chosen, the reg-
ister 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 soft-
ware. All output macrocells can be connected to an I/O
cell. If a buried macrocell is desired, the internal feed-
back path from the macrocell can be used, which frees
up the I/O pin for use as an input.
The MACH230 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.
