Timing Characteristics (continued)
Notes:
The pin-to-pin timing parameters in this table should be used instead of results reported by ORCA Foundry.
Shaded values are advance information and are valid for OR3Txxx devices only.
The FCLK delays are for a fully routed clock tree that uses the ExpressCLK input into the Fast Clock network. It includes both the input buffer
delay and the clock routing to the PFU CLK input. The delay will be reduced if any of the clock branches are not used.

Table 57. OR3C/Txxx Input to Fast Clock Setup/Hold Time (Pin-to-Pin)
OR3Cxx Commercial: VDD = 5.0 V ± 5%, 0 °C
< TA < 70 °C; Industrial: VDD = 5.0 V ± 10%, –40 °C < TA < +85 °C.
OR3Txxx Commercial: VDD = 3.0 V to 3.6 V, 0 °C
< TA < 70 °C; Industrial: VDD = 3.0 V to 3.6 V, –40 °C < TA < +85 °C.
