MAX 3000A Programmable Logic Device Family Data Sheet
Macrocells
MAX 3000A macrocells can be individually configured for either
sequential or combinatorial logic operation. Macrocells consist of three
functional blocks: logic array, product–term select matrix, and
programmable register.
Figure2
shows a MAX 3000A macrocell.
Figure 2. MAX 3000A Macrocell
Combinatorial logic is implemented in the logic array, which provides
five product terms per macrocell. The product–term select matrix
allocates these product terms for use as either primary logic inputs (to the
OR
and
XOR
gates) to implement combinatorial functions, or as secondary
inputs to the macrocell’s register preset, clock, and clock enable control
functions.
Two kinds of expander product terms (“expanders”) are available to
supplement macrocell logic resources:
■
Shareable expanders, which are inverted product terms that are fed
back into the logic array
Parallel expanders, which are product terms borrowed from adjacent
macrocells
■
The Altera development system automatically optimizes product–term
allocation according to the logic requirements of the design.
