MACH 4 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 exibility in determining pinout and allows design changes to
occur without effecting pinout.
In MACH 4 devices with 2:1 Macrocell-I/O cell ratio, each PAL block has twice as many
macrocells as I/O cells. The MACH 4 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 MACH 4 devices
with 1:1 Macrocell-I/O cell ratio allow each macrocell to drive one of eight I/O cells (Figure 9).
