Overview
The ADUC832BSZ-REEL, produced by Analog Devices Inc., is a comprehensive smart transducer front end that integrates multiple advanced functionalities on a single chip. This device features a high-performance self-calibrating multichannel 12-bit Analog-to-Digital Converter (ADC), dual 12-bit Digital-to-Analog Converters (DACs), and a programmable 8-bit microcontroller (MCU) based on the 8051 instruction set. The MCU core operates at a maximum frequency of 16 MHz, generated from a 32 kHz external crystal using an on-chip Phase-Locked Loop (PLL). The device also includes 62 kB of nonvolatile Flash/EE program memory, 4 kB of nonvolatile Flash/EE data memory, 256 bytes of RAM, and 2 kB of extended RAM.
