description

The TIBPAL22VP10’ is equivalent to the I/O /Q I/O /Q TIBPAL22V10A but offers additional flexibility in I/O /Q I/O /Q

the output structure. The improved output NC No internal connection

macrocell uses the registered outputs as inputs Pin assignments in operating mode

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. IMPACT-X is a trademark of Texas Instruments Incorporated.
