HT46R14 -- A/D Type 8-Bit OTP MCU (限用產品)

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, etc.

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