KL5KUSB2CF
USB 2.0 Controller – Quick Interface
1
Ver. 1.5
PRELIMINARY
General Description
The Kawasaki KL5KUSB2CF Controller is a quick single chip solution to interface peripheral devices to
the Universal Serial Bus (USB) 2.0 specification. The KL5KUSB2CF 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.
