Holtek HT46R47/HT46R22/HT46R23/HT46R24 A/D Microcontroller User Manual
The HT46R47/HT46R22/HT46R23/HT46R24 series are 8‑bit high‑performance RISC microcontrollers with integrated multi‑channel A/D converters and PWM outputs. They are designed for sensor signal processing, motor drive, industrial control and consumer applications, offering low power consumption, flexible I/O and various on‑chip peripherals.
This manual is divided into three parts: the first part covers hardware architecture, pin assignments and electrical characteristics; the second part describes the instruction set, programming model, registers and peripheral modules such as timers, PWM, I2C and A/D converters; the third part provides information on Holtek development tools, quick‑start procedures, and application examples. This manual is written in Chinese.
