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.

MAX II CPLD EPM2210 System Controller

The board utilizes the EPM2210 System Controller, an Altera MAX

II CPLD, for the

following purposes:

■ FPGA configuration from flash memory

■ Power consumption monitoring

■ Virtual JTAG interface for PC-based GUI

■ Control registers for clocks

■ Control registers for remote system update
