HT46R34 Datasheet (Holtek Semiconductor)

HT46R34, (HT46R32 / HT46R34) A/D

The HT46R32 and HT46R34 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.
