Description

The HT46R321 is 8-bit, high performance, RISC architecture microcontroller devices. With their fully integrated A/D converter they are especially suitable for applications which interface to analog signals, such as those from sensors. The addition of an internal operational amplifier/comparator and PWM modulation functions further adds to the analog capability of these devices.

With the HT46R321 comprehensive features of low power consumption, I/O flexibility, programmable frequency divider, timer functions, oscillator options, multi-channel A/D Converter, OP/Comparator, Pulse Width Modulation function, LED driver, Power-down and wake-up functions etc, the application scope of these devices is broad and encompasses areas such as sensor signal processing, motor driving, industrial control, consumer products, subsystem controllers, etc.
