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.
