This user manual introduces the hardware structure, characteristics, technical specifications, core features, peripheral features, and usage considerations of HT46R47, HT46R22, HT46R23, HT46R24 A/D type microcontrollers produced by Shengqun Semiconductor Co., Ltd.
This manual provides detailed information on the HT46R47, HT46R22, HT46R23 and HT46R24 A/D‑type microcontrollers, including hardware structure, system block diagram, pin assignments, and the full register set. It also describes the integrated multi‑channel A/D converter, PWM modules, I²C interface, timers, interrupt system, low‑voltage reset and power‑down features.
The third part of the document introduces Holtek’s development environment, including the HT‑IDE IDE, HT‑ICE emulator and OTP programming tools, with step‑by‑step instructions for creating projects, compiling code and programming the devices. This manual is written in Chinese.
| Working voltage (4 MHz) | 2.2 V – 5.5 V |
|---|---|
| Working voltage (8 MHz) | 3.3 V – 5.5 V |
| Power consumption (5 V, 4 MHz) | Typical 2 mA |
| Operating temperature range | -40 °C to 85 °C (industrial) |
| Program memory (HT46R47/HT46R22) | 2 K × 14 OTP/Mask ROM |
The LVR activates when the supply voltage falls between 0.9 V and the LVR threshold.
They operate from –40 °C to 85 °C, with storage temperatures from –50 °C to 125 °C.
Holtek provides the HT‑IDE integrated development environment, the HT‑ICE emulator, and OTP programming hardware.
