General Description
The HT56R64 is a Tiny Power TM A/D Type with LCD 8-bit high performance RISC architecture microcontroller, designed especially for applications that interface directly to analog signals and which require an LCD interface. The device includes an integrated multi-channel Analog to Digital Converter, four Pulse Width Modulation outputs and an LCD driver. With its fully integrated SPI and I2C functions, designers are provided with a means of easy munication with external peripheral hardware. The benefits of integrated A/D, LCD, and PWM functions, in...
