ORCA Series 3C and 3T FPGAs

Timing Characteristics (continued)

Table 45. Synchronous Memory Read Characteristics

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.

Note: The table shows worst-case delays. ORCA Foundry reports the delays for individual paths within a group of paths representing the same

timing parameter and may accurately report delays that are less than those listed.
