General Description
●The HT46R51/HT46R52 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 advan
●tages of low power consumption, I/O flexibility, timer functions, oscillator options, multi-channel A/D converter, Pulse Width Modulation function, HALT and wake-up functions, watchdog timer, as well as low cost, enhance the versatility of these devices to suit a wide range of A/D application possibilities such as sensor signal processing, chargers, motor driving, industrial control, consumer products, subsystem controllers, etc.
