GENERAL DESCRIPTION

The MACH230 is a member of AMD鈥檚 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,

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.
