HT46RU232 -- A/D Type 8-Bit OTP MCU with UART
General Description
The HT46RU232 is 8-bit, high performance, RISC architecture
microcontroller devices specifically designed for A/D applications that interface directly to analog signals,
such as those from sensors.
The advantages of low power consumption, I/O flexibility,
programmable frequency divider, timer functions, oscillator options, multi-channel A/D Converter, Pulse
Width Modulation function, I2C interface, UART bus, HALT and wake-up functions, enhance the versatility of
these devices to suit a wide range of A/D application possibilities such as sensor signal processing, motor
driving, industrial control, consumer products, subsystem controllers, etc.
