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.
NC − No internal connection
Pin assignments in operating mode
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.
