HT46RB50 -- A/D Type USB 8-Bit MCU

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.
