KCUSB3
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.
