USB Controller with Host and Peripheral Ports (25)

A Cypress CY7C67300 embedded USB host controller provides the 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 1 connector (J19) and the USB Peripheral 1 connector (J2). SIE2
is connected only to the USB Peripheral 2 connector.
Note:
peripheral connector, but not both at the same time.
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 (U17) or
can be downloaded from a host computer via a peripheral connector. The serial port of the
USB controller is connected to J32 and J33 through an RS-232 transceiver to assist with
debug.
