Description
KL5KUSB116
USB to Serial
The Kawasaki USB to Serial enables your system to have the capability to communicate between the
USB (Universal Serial Bus) port and serial port peripherals. This device meets the USB 1.0/1.1 and
standard serial port specifications. All the advantages of USB are available to peripherals with serial port
interface such as plug and play capabilities. With the USB Standard of high-speed data transfers, this
device is ideal for connections to high-speed modems or ISDN terminal adapters. Kawasaki’s device and
software enable the USB interface to be transparent to the peripheral and requires no firmware changes.
This makes it possible for peripherals with serial interfaces to easily interface with USB with minimum
modifications. This feature is ideal for Legacy applications.

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.
