MAX 7000A macrocells can be individually configured for either sequential or combinatorial logic operation. The macrocells consist of three functional blocks: the logic array, the product-term select matrix, and the programmable register. Below Figure shows a MAX 7000A 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 when unlock epm7128 cpld chip memory.

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.
