Military QuickRAM Family Data Sheet Rev. C
c. Only one output at a time. Duration should not exceed 30 seconds.
d. Maximum ICC is 5 mA all military grade devices. For AC conditions, contact QuickLogic customer engineering.
AC Characteristics at VCC = 3.3 V, TA = 25° C (K = 1.00)
To calculate delays, multiply the appropriate K factor from Table 4 by the numbers provided in Table 6
through Table 15.

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