ispMACH 4A Family

Output Switch Matrix

The output switch matrix allows macrocells to be connected to any of several I/O cells within a PAL block.

This provides high flexibility in determining pinout and allows design changes to occur without effecting

pinout.

In ispMACH 4A devices with 2:1 Macrocell-I/O cell ratio, each PAL block has twice as many macrocells

as I/O cells. The ispMACH 4A output switch matrix allows for half of the macrocells to drive I/O cells

within a PAL block, in combinations according to Figure 9. Each I/O cell can choose from eight macrocells;

each macrocell has a choice of four I/O cells. The ispMACH 4A devices with 1:1 Macrocell-I/O cell ratio

allow each macrocell to drive one of eight I/O cells (Figure 9).
