ADuC842 MicroConverter® is a high-performance, 62KB FLASH MCU, 12-bit ADC and DAC in a small package, suitable for industrial, medical, and consumer applications.
The ADuC842 is a mixed‑signal microconverter that integrates a 12‑bit, 400 kSPS ADC, dual 12‑bit DACs, a 16‑MIPS 8052‑compatible MCU core, and 62 KB of on‑chip flash memory. It operates from a 3 V to 5 V supply and includes on‑chip peripherals such as UART, I²C, SPI, PWM, timers, and a temperature sensor.
Key features include a high‑speed 16.777 MHz core clock, low power consumption (6 mA normal mode at 5 V), eight analog input channels, and extensive on‑chip memory options. The datasheet provides detailed electrical specifications, absolute maximum ratings, pin descriptions, and package dimensions for both the 52‑lead QFP and 56‑lead chip‑scale packages.
