USB to Serial

PLL Clock Generator

The PLL circuitry is provided to generate the internal 48MHz clock. This circuitry is designed to

allow use of a low cost 12 MHz external crystal which is connected to CLK and X2. If an external

12 MHz clock is available in the application, it may be used in lieu of the crystal circuit and

connected directly to the CLK input pin.

USB Interface

The USB controller meets the Universal Serial Bus (USB) specification ver 1.0/1.1. The

transceiver is capable of transmitting and receiving serial data at the USB’s full speed, 12

Mbits/sec data rate. The driver portion of the transceiver is differential, while the receive section

is comprised of a differential receiver and two single ended receivers. Internally, the transceiver

interfaces to the SIE logic. Externally, the transceiver connects to the physical layer of the USB.

UART Serial Interface

One UART serial port is provided. The port can be configured for a wide selection of baud rates,

300 to 230.4 K baud, and support a set of control signals. The UART provides a means for

external serial devices to access the USB.

Debug UART

An independent UART serial port is provided for debug and code development. The port can be

configured for a wide selection of baud rates, 7200 to 115.2K baud. The port provides transmit

and receive data support only.

Serial EEPROM Support

The USB Controller serial interface is used to provide access to external EEPROM’s. The

interface can support a variety of serial EEPROM formats.
