description

The

TIBPAL22VP10’

is

equivalent

to

the

TIBPAL22V10A but offers additional flexibility in

the output structure. The improved output

macrocell uses the registered outputs as inputs

when in a high-impedance condition. This

provides two additional output configurations for a

total of six possible macrocell configurations all of

which are shown in Figure 1.

These devices contain up to 22 inputs and 10 outputs. They incorporate the unique capability of defining and

programming the architecture of each output on an individual basis. Outputs may be registered or nonregistered

and inverting or noninverting. In addition, the data may be fed back into the array from either the register or the

I/O port. The ten potential outputs are enabled through the use of individual product terms.

Further advantages can be seen in the introduction of variable product term distribution. This technique

allocates from 8 to 16 logical product terms to each output for an average of 12 product terms per output. This

variable allocation of terms allows far more complex functions to be implemented than in previously available

devices.

These devices are covered by U.S. Patent 4,410,987.
