This document describes the features of the HT46R23/HT46C23 A/D type eight-bit microcontroller, including operating voltage range, number of input/output ports, programmable timer/counters, memory capacity, A/D converter, PWM output, etc.
The HT46R23 (OTP version) and HT46C23 (masked version) are 8‑bit RISC microcontrollers designed for sensor A/D conversion, motor control, industrial and consumer applications. They provide flexible I/O, programmable timers, built‑in oscillators, watchdog, and low‑power halt/wake functions.
The document includes functional descriptions, pin‑out diagrams, electrical characteristics, timing parameters, register maps and mechanical dimensions for the 24‑pin SKDIP/SOP and 28‑pin SOP packages. This manual is written in Chinese.
