Electrical Specifications
AC Characteristics at V
CC = 3.3 V, TA = 25°C (K = 1.00)
To calculate delays, multiply the appropriate K factor from Table 9 by the numbers provided in Table 3
through Table 7.

Combinatorial Delay b
b. These limits are derived from a representative selection of the slowest paths through the pASIC 3 logic cell including typical net
delays. Worst case delay values for specific paths should be determined from timing analysis of your particular design.
