HT46R*** -- A/D Type USB 8-Bit MCU
General Description
This device is an 8-bit high performance RISC architecture microcontroller designed for USB product applicati***. 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 keyboa*** and joystick. A HALT feature is included to reduce power c***umption.
