HT46R12 -- A/D Type 8-Bit OTP MCU

General Description

The device are 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, 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.

The device also provides two comparators and a programmable pulse generator (PPG), hence, it is particularly suitable for use in products such as induction cooker and home appliances.
