Notes:
1. All –3 speed grades have been discontinued.
2. For dual-module macros, use tPD + tRD1 + tPDn , tRCO + tRD1 + tPDn , or tPD1 + tRD1 + tSUD , whichever is appropriate.
3. Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating device
performance. Post-route timing analysis or simulation is required to determine actual performance.
