November 1, 2006

General Description

This device is an 8-bit high performance RISC

architecture microcontroller designed for USB product

applications. It is particularly suitable for use in products

such as USB and/or SPI touch-panels, USB and/or SPI

touch-pads, PS II joysticks, XBOX joysticks, USB Mice

keyboards and joystick. A HALT feature is included to

reduce power consumption.
