PEELTM 22CV10A
Additional Macrocell Configurations
Besides the standard four-configuration macrocells, each
PEEL™22CV10A provides an additional eight configura-
tions (twelve total) that can be used to increase design flex-
ibility

configurations, specify PEEL™22CV10A+. Also, select the
PEEL™22CV10A+ for programming.
