Notes:  
1. For dual-module macros, use tPD1 + tRD1 + tPDn, tCO + tRD1 + tPDn or tPD1 + tRD1 + tSUD, whichever is appropriate.  
2. 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.  
3. Data applies to macros based on the S-module. Timing parameters for sequential macros constructed from C-modules can be obtained from  
the DirectTime Analyzer utility.  
4. Set-up and hold timing parameters for the input buffer latch are defined with respect to the PAD and the D input. External set-up/hold timing  
parameters must account for delay from an external PAD signal to the G inputs. Delay from an external PAD signal to the G input subtracts  
(adds) to the internal set-up (hold) time.  
5. VCC = 3.0V for 3.3V specifications.
