MACH210AQ-12JC, AMD

The MACH210 is a member of AMD’s high-performance

EE CMOS MACH 2

device family. This device has

approximately six times the logic macrocell capability of

the popular PAL22V10 without loss of speed.

The MACH210 consists of four PAL blocks intercon-

nected by a programmable switch matrix. The four PAL

blocks are essentially “PAL22V16” structures complete

with product-term arrays and programmable macro-

cells, including additional 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 MACH210 has two kinds of macrocell: output and

buried. The MACH210 output macrocell provides regis-

tered, latched, or combinatorial outputs with program-

mable 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 MACH210 has dedicated buried macrocells which,

in addition to the capabilities of the output macrocell,

also provide input registers or latches for use in

synchronizing signals and reducing setup time require-

ments.
