ADuC842 MicroConverter® is an integrated 12-bit ADC, DAC and high-performance 62KB FLASH MCU from Analog Devices.
The ADuC842 is a 12‑bit micro‑converter that integrates a high‑speed ADC, dual DACs, a 16‑MIPS 8052‑compatible MCU and a range of on‑chip peripherals such as UART, I²C, SPI, PWM and a temperature sensor. It operates from 3 V or 5 V supplies and offers up to 400 kSPS sampling for the ADC.
The document provides full electrical specifications, absolute maximum ratings, pin‑function descriptions, ordering information for the 52‑lead QFP and 56‑lead chip‑scale packages, and mechanical dimensions. It also includes reliability data for the Flash/EE memory and recommended handling precautions.
