ADuC841/ADuC842/ADuC843 is a high-performance, low-power microcontroller with an integrated high-precision, high-speed 12-bit ADC and 12-bit DAC.
The ADuC841/ADuC842/ADuC843 family are 12‑bit microcontrollers that integrate a high‑performance ADC, dual DAC, and a single‑cycle 20 MHz 8052‑compatible core on a single chip. They offer up to 62 kB of on‑chip Flash, 4 kB of data memory, and a range of peripherals including UART, I²C, SPI, PWM, and watchdog timer.
This document contains detailed specifications, absolute maximum ratings, pin‑out diagrams, functional block descriptions, memory organization, peripheral register maps, power‑supply requirements, and development‑tool information for the ADuC841, ADuC842, and ADuC843 devices.
