MAX 7000 Programmable Logic Device Family Data Sheet
Each LAB is fed by the following signals:
■
■
■
36 signals from the PIA that are used for general logic inputs
Global controls that are used for secondary register functions
Direct input paths from I/O pins to the registers that are used
for fast setup times for MAX 7000E and MAX 7000S devices
Macrocells
The MAX 7000 macrocell can be individually configured for either
sequential or combinatorial logic operation. The macrocell consists
of three functional blocks: the logic array, the product-term select
matrix, and the programmable register. The macrocell of EPM7032,
EPM7064, and EPM7096 devices is shown in
