(To calculate delays, multiply the appropriate K factor in the "Operating Range" section by the following numbers.)
Logic Cells
RAM Cell Synchronous Write Timing
Notes:
[5]Stated timing for worst case Propagation Delay over process variation at VCC=3.3V and TA=25
°
C. Multiply by
the appropriate Delay Factor, K, for speed grade, voltage and temperature settings as specified in the Operating
Range.
[6]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 anal-
ysis of your particular design.
