BGA package.
f For more information about Cyclone III devices, refer to the Cyclone III Device
Handbook .
Table 2–2 lists the main Cyclone III device features.
Table 2–3 lists the Cyclone III component reference and manufacturing information.
U23 and U24 SRAM The SRAM devices connect to the MAX II device as well as the flash memory
device.
U11, U12, U13,
U25, U26 DDR2 SDRAM Four ×16 devices and a single ×8 device.
Components and Interfaces
U6 USB device USB device that provides JTAG programming of on-board devices, including
the Cyclone III device and flash memory device.
U3 Ethernet cable jack The RF-45 jack is for Ethernet cable connection. The connector is fed by a
10/100/1000 base T PHY device with an RGMII interface to the Cyclone III
device.
J8, J9 HSMC Port A and Port B High-speed mezzanine header allows for the connection of HSMC daughter
cards.
Power Supply
J2 DC power jack 14–20 V DC power source.
SW2 Input Switches the board’s power on and off.
