The ADuC832 MicroConverter® is a fully integrated 12-bit data acquisition system-on-a-chip. Like all of ADI's MicroConverter products, it features precision A/D & D/A conversion and a Flash microcontroller on a single chip. The ADuC832 is 100% hardware backward compatible with the ADuC812, except that it requires a different crystal. If you require full hardware backward compatibility with the ADuC812, use the ADuC831 instead. The ADuC832 is available in 52-pin PQFP or 56-pin CSP packages and operates on a 3V or 5V power supply.
