The MAX 7000A architecture includes the following elements:
Logic array blocks (LABs)
Macrocells
Expander product terms (shareable and parallel)
Programmable interconnect array
I/O control blocks
The MAX 7000A architecture includes four dedicated inputs that can be used as general-purpose inputs or as high-speed, global control signals (clock, clear, and two output enable signals) for each macrocell and I/O pin. Below Figure shows the architecture of MAX 7000A devices.

Note:
EPM7032AE, EPM7064AE, EPM7128A, EPM7128AE, EPM7256A, and EPM7256AE devices have six output enables. EPM7512AE devices have 10 output enables.
Logic Array Blocks
The MAX 7000A device architecture is based on the linking of
high-performance LABs. LABs consist of 16-macrocell arrays, as shown in above Figure. Multiple LABs are linked together via the PIA, a global bus that is fed by all dedicated input pins, I/O pins, and macrocells.

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
