ADuC812 is a microcontroller with 8-channel, 12-bit ADC, embedded flash and UART function.
The ADuC812 is a fully integrated 12‑bit microconverter that combines an ADC, dual DACs, on‑chip flash/EE memory, and an 8051‑compatible MCU core on a single chip. It supports 3 V or 5 V operation and includes a range of on‑chip peripherals such as UART, SPI, I²C, watchdog timer, and power‑supply monitor.
The handbook details the device's features, applications, electrical specifications, absolute maximum ratings, pin configurations, ordering options, and pin‑function descriptions. It also includes timing specifications, memory organization, and guidelines for power‑supply and grounding design.
