Featured Device: Arria II GX Device

Arria II GX FPGA Development Board Reference Manual February 2011 Altera Corporation

Table 2–4 lists the I/O count for the EP2AGX125 and EP2AGX260 device.

Table 2–5 lists the Arria II GX device pin count and usage by function on the

development board.

Migration Support

Although the target FPGA for this development board is the EP2AGX125EF35 device,

the first device released in this 40nm FPGA family, the board supports migration to

the largest Arria II GX device, the EP2AGX260EF35.

Table 2–6 describes the features of the Arria II GX EP2AGX260EF35 device.
