ORCA Series 4 FPGAs
Pin Information (continued)
Package Compatibility
Table 68 provides the number of user I/Os available for the ORCA Series 4 FPGAs for each available package.
Each package has six dedicated conguration pins.

Edge Clock Input Pins. The input buffers for fast edge clocks are only available at the C I/O pad. The C I/Os are
shown in the following pinout tables under the I/O pad columns as those ending in C.
680 PBGAM Differential I/O Pairs. Note that the OR4E02 device in the 680 PBGAM package has two less dif-
ferential I/O pairs available than the OR4E04 or OR4E06, even though the total number of user I/Os are the same
for all three devices.
