Cyclone III Device Pin Count Board Component Pins SRAM/flash (shared bus) 72 SDRAM (DDR) 42 (1) (2) Push-buttons 4 LEDs 4 (1) USB-Blaster/configuration 4 HSMC 84 (1) Total Pins Used 210 Total EP3C25F324 pins 214 Unused pins 4 Notes to Table 2-3: (1) (2) The Cyclone III EP3C25F324 only supports one I/O standard in an I/O bank. I/O banks 3 and 4 are shared among the DDR, HSMC and LEDs. In several DDR designs, some of the I/O pins that share the same banks with the DDR are unavailable for use due to different I/O standards. Therefore, if you have added DDR to your system, I/O banks 3 and 4 is to be configured as SSTL-2 only while the HSMC and LEDs pins which are not using SSTL-2, should be removed. You can configure the Cyclone III device via the on-board USB-BlasterTM or through the JTAG interface using an external programming cable (sold separately). f Clocking Circuitry For additional information about Altera devices, go to www.altera.com/products/devices. The Cyclone III FPGA starter board's clocking circuitry is designed to be simple and easy to use. A single 50-MHz clock input is used and all other clocks are generated using the Cyclone III device's phase-locked loops (PLLs). The dedicated PLLs are used to distribute the flash, SSRAM, and HSMC clocks. Table 2-4 shows the clock pinout. Table 2-4.

To supply an external voltage, remove the jumper and connect the external supply to pin 2. (Pin 2 has a rounded shape on the bottom of the board.) JP8 Removing the shunt enables the embedded USB-Blaster circuitry. When the shunt is in place, use any external cable such as the ByteBlaster II, EthernetBlaster, or USB-Blaster cable to configure the Cyclone III device. (The board ships without the JTAG header populated.) This section describes the following Cyclone III FPGA starter board's interface blocks: USB interface HSMC expansion connector General user interfaces USB Interface The USB-Blaster circuitry is built onto the board. Plug the USB cable (provided with the kit) into USB connector J3 on the board and the other end to a USB port on your computer to program and communicate with the Cyclone III device via the JTAG port. A USB physical connection is used to enable computers to communicate with the starter board. To simplify the USB interface, the board contains a FTDI FT245 FIFO circuit. The data from the FTDI chip is translated into a JTAG stream using the Altera EMP3128A CPLD connected to the Cyclone III device's dedicated JTAG port. The 5 V supply for the FTDI device is drawn from the USB connection. The rest of the circuit operates on 3.3 V supply with a maximum of 100 mA and 1.8 V supply with a maximum of 900 mA voltage. 2-8 Cyclone III FPGA Starter Board Reference Manual Altera Corporation April 2012 Board Components and Interfaces HSMC Expansion Connector The board provides one HSMC connector. The HSMC connector is a modified version of standard high-speed Samtec connectors. To provide better signal integrity between the host boards and daughtercards when using high-speed transceivers, the standard high-speed Samtec connector is modified by removing every third pin in bank -1. 1 CMOS utilization of the HSMC pins is assumed and no options for supporting other differential signaling is provided with the board. The eight clock-data-recovery high-speed transceiver channels are not connected. Table 2-6 lists the ordering codes and shows the relationship between the standard Samtec Q-series connectors and the modified parts' ordering codes. Table 2-6.

To provide various voltage options, the board uses several Linear Technologies' regulators. Switching regulators are used for digital circuits and linear regulators are used for analog circuits. Board regulators are used to generate the voltages listed in Table 2-17. Table 2-17.
