USB Controller – Quick Interface
General Description
The Kawasaki KCUSB3 Controller is a quick single chip solution to interface peripheral devices to the
Universal Serial Bus (USB). The KCUSB3 has been specifically designed to provide a simple and fast
method of designing interfaces for peripheral devices to the USB port. This has been accomplished by its
highly integrated functionality and flexible General Purpose I/O (GPIO) that can be configured to your
system requirements. This device has been configured with a wide range of capabilities for your
immediate use or evaluation. The device can then be reconfigured for your specific application. You can
directly access the embedded processor’s address and data lines to use external programmable logic for
evaluation before configuring the GPIO for your final device. The SIE (Serial Interface Engine) is fully
compatible with the USB specification.

Function Description
16 Bit Processor
The integrated 16 bit processor serves as a micro controller for USB peripherals. The processor
can execute approximately five million instructions per second. With this processing power it
allows the design of intelligent peripherals that can process data prior to passing it on to the host
PC, thus improving overall performance of the system. The masked ROM (4K X 16) in the
KCUSB3 or external memory contains a specialized instruction set that has been designed for
highly efficient coding of processing algorithms and USB transaction processing.
The 16-bit processor is designed for efficient data execution by having direct access to the RAM
Buffer, external memory, I/O interfaces, and all the control and status registers. The
divide/multiply feature expands the capability of USB peripherals.
The processor contains sixteen general-purpose registers along with several special purpose
registers including a flag register and an interrupt enable register. Eight of these registers can be
used for indirect Addressing, with optional indexed and auto increment modes available. One of
these general-purpose registers is additionally used as a stack pointer. The register set is
mapped into RAM, and can be easily relocated for fast context switching.
The processor supports prioritized vectored hardware interrupts. In addition, as many as 240
software interrupt vectors are available.
The processor provides six addressing modes, supporting memory-to-memory, memory-to-
register, register-to-register, immediate-to-register or immediate-to-memory operations. Register,
direct, immediate, indirect, and indirect indexed addressing modes are supported. In addition,
there is an auto-increment mode in which a register, used as an address pointer is automatically
incremented after each use, making repetitive operations more efficient both from a programming
and a performance standpoint.
The processor features a full set of program control, logical, and integer arithmetic instructions.
All instructions are sixteen bits wide, although some instructions require operands, which may
occupy another one or two words. Several special “ short immediate” instructions are available,
so that certain frequently used operations with small constant operand will fit into a 16-bit
instruction.

USB Controller – Quick Interface
The Processor – Divide/Multiply function
The processor’s divide/multiply function contains all the instructions of the base processor that
additionally includes integer divide and multiply instructions. A signed multiply instructions takes
two 16-bit operands and returns a 32-bit result. A signed divide instruction divides a 32-bit
operand by a 16-bit operand.
RAM Buffer
The USB controller contains a 3K byte (1.5K X 16) internal buffer memory. The memory is used
to buffer data and USB packets and accessed by the 16 Bit processor and the SIE. USB
transactions are automatically routed to the memory buffer. The 16-bit processor has the ability
to set up pointers and block sizes in buffer memory for USB transactions. Data is read from the
interface and is processed and packetized by the 16-bit I/O processor.
PLL Clock Generator
The PLL circuitry is provided to generate the internal 48MHz clock requirements. This circuitry is
designed to allow use of a low cost 12 MHz external crystal which is connected to the KCUSB3
pins X1 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 X1 input pin.
USB Interface
The USB controller meets the Universal Serial Bus (USB) specification ver 1.0. 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.
A/D interface
The integrated A/D interface is a ten bit A/D interface with eight Analog Inputs and converts data
at 100K samples per second.
PWM Interface
Four PWM output channels are available with each channel capable of converting 10 bits at a
rate up to 48 KHz.
UART Interface
Supports a transfer rate of 900 to 115.2K baud.
General Purpose I/O
Up to 25 general purpose I/O signals are available. Most of the GPIOs can be configured for
special purpose functions such as PWM, Serial EEPROM interface, Digital Input, etc.

Serial EEPROM Support
The USB Controller serial interface is used to provide access to external EEPROM’s. The
interface is implemented using General Purpose I/O signals and can support a variety of serial
EEPROM formats.
Custom Logic Interface
The internal 16 bit data and address bus is connected to the Custom Logic block allowing custom
logic to interface to the processor and to access a selection of GPIO pins.
Development Tools
To assist in the development of USB products, an evaluation board is available as well as a set of
software tools and debuggers. Compilers and debuggers are available through third party
suppliers.
