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.

Features

• Advanced 16 Bit processor for USB transaction
processing and control data processing

• USB interface ver 1.0/1.1 compliant

• Transceivers and SIE (Serial Interface Engine)

• Internal Clock Generation

• Utilizes low cost external crystal circuitry

• 1.5K x 16 Internal RAM buffer

• 2 IRQ

• 8 Channel, 10 Bit A/D
