General Description

The HT46R343 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.
