MAX 9000 Programmable Logic Device Family Data Sheet

Parallel Expanders

Parallel expanders are unused product terms that can be allocated to a

neighboring macrocell to implement fast, complex logic functions.

Parallel expanders allow up to 20 product terms to directly feed the

macrocell OR logic, with five product terms provided by the macrocell and

15 parallel expanders provided by neighboring macrocells in the LAB.

Figure 5 shows how parallel expanders can feed the neighboring

macrocell.
