This user manual introduces the hardware structure, characteristics, technical specifications, and peripheral features of HT46R47, HT46R22, HT46R23, and HT46R24 A/D-type microcontrollers from Jilin Semiconductor Co., Ltd. It also includes the system structure, timing and pipeline structure, program counter, stack, arithmetic and logic unit, program memory, data memory, special function registers, input/output ports and control registers, pulse width modulation registers, I2C bus registers, A/D conversion registers, input/output ports, timers/counters, input/output interfaces, pulse width modulators, analog-to-digital converters, I2C bus serial interface, interrupts, reset and initialization, etc.
This user manual provides comprehensive specifications and usage instructions for the Holtek HT46R47, HT46R22, HT46R23, and HT46R24 A/D-type microcontrollers. These are high-performance, low-power 8-bit RISC devices designed to directly process analog signals from sensors. This manual is written in Chinese.
| Architecture | 8-bit High Performance RISC Structure |
|---|---|
| Operating Voltage (4MHz) | 2.2V to 5.5V |
| Operating Voltage (8MHz) | 3.3V to 5.5V |
| Program Memory (HT46R24) | 8K x 16 OTP/Mask ROM |
| Data Memory (HT46R24) | 384 x 8 SRAM |
| Stack Depth (HT46R24) | 16-level |
The microcontrollers operate in an industrial grade temperature range of -40°C to 85°C.
The typical power loss is 2mA when the crystal oscillator for the ADC is disabled.
These microcontrollers are widely used in sensor signal processing, motor driving, industrial control, and consumer products.
