General 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.
