Description

The HT46R322 and HT46R342 are 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 HT46R342 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, 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.

The HT46R342 is under development and will be available soon.
