ADUC832 1.3MIPS 8052 MCU + 62kB Flash + 8-Ch 12-Bit ADC + Dual 12-Bit DAC

Description: The ADUC836 MicroConverter is a fully integrated 16-bit data acquisition system-on-a-chip. Like all of ADI's MicroConverter products, it features precision A/D and D/A conversion along with a Flash Microcontroller on a single chip. The ADUC836 is fully backward compatible (both hardware and software) with the ADuC816. It is available in 52-pin PQFP or 56-pin CSP packages and operates on a 3V or 5V power supply. The device functions with a 32 kHz crystal, utilizing an on-chip PLL to generate a high-frequency clock of 12.58 MHz. This clock is routed through a programmable clock divider, which produces the operating frequency for the MCU core clock. The Microcontroller core is based on the 8052 architecture, making it compatible with the 8051 instruction set, with 12 core clock periods per machine cycle.

The ADUC836 MicroConverter represents a significant advancement in integrated data acquisition systems, combining the functionality of analog-to-digital (A/D) and digital-to-analog (D/A) conversion along with a microcontroller in a single package. This integration facilitates compact design solutions for applications requiring precise data processing and control.

The device's compatibility with the ADuC816 ensures a smooth transition for users upgrading from previous models, minimizing the need for redesign efforts. The availability of both 52-pin PQFP and 56-pin CSP packages provides flexibility in design, allowing engineers to select the optimal footprint for their specific application needs.

Operating on a dual voltage of 3V or 5V enhances the versatility of the ADUC836, making it suitable for a wide range of applications, from battery-powered devices to more robust systems. The use of a 32 kHz crystal oscillator, paired with an on-chip phase-locked loop (PLL), enables the generation of a stable high-frequency clock at 12.58 MHz, which is essential for maintaining precise timing in data acquisition processes.

The programmable clock divider further enhances the device's flexibility, allowing designers to tailor the microcontroller core clock frequency to meet the requirements of their application. The 8052 core architecture ensures that existing 8051 code can be utilized without modification, thus streamlining development processes and reducing time-to-market.
