ADUC816 1MIPS 8052 MCU + 8kB Flash + Dual 16-Bit ADC + 12-Bit DAC

The ADUC831 MicroConverter is a fully integrated 12-bit data acquisition system-on-a-chip. Like all of Analog Devices Inc.'s MicroConverter products, it features precision A/D and D/A conversion along with a Flash Microcontroller on a single chip. The ADUC831 is fully compatible with the ADuC812. It is available in 52-pin PQFP or 56-pin CSP packages and operates on a 3V or 5V power supply. The Microcontroller core is based on the 8052 architecture, ensuring compatibility with the 8051 instruction set, and it operates at 12 clock periods per machine cycle. The device includes 62 kBytes of non-volatile Flash EE program memory, 4 kBytes of non-volatile Flash EE data memory, 256 bytes of RAM, and 2 kBytes of extended RAM, all integrated on-chip.

The ADUC831 MicroConverter is designed for applications requiring precise data acquisition and processing capabilities. The device's 12-bit resolution allows for high accuracy in analog-to-digital conversions, making it suitable for various measurement and control applications. The integrated Flash Microcontroller provides flexibility in programming and allows for the storage of user-defined algorithms directly on the chip.

The presence of 62 kBytes of non-volatile Flash EE program memory enables the storage of complex programs, while the 4 kBytes of non-volatile Flash EE data memory can be utilized for storing configuration parameters or calibration data. The additional RAM and extended RAM support enhance the processing capabilities of the device, allowing for efficient data handling and manipulation during operation.

The 8052 core architecture ensures that developers familiar with the 8051 instruction set can easily adapt their existing codebases for use with the ADUC831, facilitating a smoother transition for projects that may have previously utilized the ADuC812. The choice of package types, including 52-pin PQFP and 56-pin CSP, provides flexibility in design and integration into various electronic systems.

With its dual power supply capability of 3V or 5V, the ADUC831 can be utilized in low-power applications, making it ideal for battery-operated devices. The combination of high-performance analog and digital processing capabilities in a single chip simplifies design complexity and reduces the overall footprint of electronic systems, promoting efficiency in both design and manufacturing processes.The ADUC831 MicroConverter is a fully integrated 12-bit data acquisition system-on-a-chip.
