HT46R46/HT46C46/HT46R47/HT46C47 - economy A / D Type 8-Bit MCU 

 Summary 

 HT46R46/HT46C46 and HT46R47/HT46C47 eight high-performance RISC microcontroller, designed specifically for A / D converter products, such as sensor signal input. The masks versions HT46C46 HT46R46 HT46C47 with the OTP version, Using the HT46R47 pin-and function exactly the same. 

 Low-power I / O using a flexible, programmable frequency divider, timer functions, oscillator options, multi-channel A / D conversion, pulse measurement capabilities, suspend and wake-up function, so that this single chip can be widely used sensors A / D conversion, motor control, industrial control, consumer products and other systems.
