A Cypress CY7C67300 embedded USB host controller provides USB connectivity for the
board. The USB controller supports host and peripheral modes of operation. The USB
controller has two serial interface engines (SIE) that can be used independently. SIE1 is
connected to the USB Host connector (P18). SIE2 is connected only to the USB Peripheral
connector (P17).
The USB controller has an internal microprocessor to assist in processing USB commands.
The firmware for this processor can be stored in its own dedicated IIC EEPROM (U28) or
can be downloaded from a host computer via a peripheral connector. The USB controller's
serial port is connected to J30 through an RS-232 transceiver to assist with debug. Jumper
J50 can be installed to prevent the USB controller from executing firmware stored in the IIC
EEPROM.
The two onboard Xilinx XCF32P Platform Flash PROM configuration storage devices offer
a convenient and easy-to-use configuration solution for the FPGA. The Platform Flash
PROM holds up to two separate configuration images (up to four with compression) that
can be accessed through the configuration address switches. To use the Platform Flash
PROM to configure the FPGA, the configuration DIP switch must be set to the correct
position.
