The ADuC812 is an 8051-based microcontroller core with 8-channel 12-bit ADC and embedded Flash, with high precision, high speed and low power consumption.
The ADuC812 is a fully integrated 12‑bit data‑acquisition system that combines a high‑performance multichannel ADC, dual DAC, and an 8051‑compatible microcontroller core on a single chip. It provides 8‑bit flash program memory, 256 B SRAM, watchdog timer, power‑supply monitor and a range of serial interfaces (UART, SPI, I²C).\n\nThe datasheet lists the device’s electrical parameters, pin configurations, package options (52‑lead MQFP and 56‑lead chip‑scale), and recommended design considerations. It also includes detailed specifications for the ADC and DAC blocks, timing characteristics, and power consumption figures for various operating modes.
