ADUC814ARU

Microcontrollers Overview

The ADUC814ARU is a MicroConverter device integrating a 247 kSPS, 12-bit ADC with an embedded 8052 MCU. It features 8 kB Flash/EE program memory, 640 bytes Flash/EE data memory, and 256 bytes RAM. The unit operates on 3 V or 5 V supplies within the -40°C to +125°C range. Key peripherals include dual 12-bit DACs, three 16-bit timers, UART, SPI/I²C interfaces, and a watchdog timer.

Microcontrollers Feature Summary

• Integrates high-speed multichannel analog-to-digital conversion with an 8052-compatible microcontroller core.
• Includes nonvolatile Flash/EE memory for both program storage and persistent data retention.
• Provides dual precision digital-to-analog converters with programmable reference capabilities.
• Supports in-circuit serial download and single-pin emulation via dedicated debug pins.

Microcontrollers Applications

• Optical networking laser power control
• Base station power amplifier bias control
• Precision instruments and smart sensors
• Battery-powered system monitors

Microcontrollers Procurement Notes

Verify the specific suffix 'ARU' corresponds to the 28-lead TSSOP package and industrial temperature range. Confirm RoHS compliance status through official documentation. Check for end-of-life notifications as this component series may be discontinued. Ensure voltage ratings match your 3 V or 5 V supply requirements.

Microcontrollers Selection Notes

Select this part when a compact solution combining high-resolution data acquisition and processing is required. The integrated PLL allows operation from low-frequency crystals while maintaining high-speed ADC performance. Consider the available I/O lines and memory size against application constraints before choosing alternative members of the ADuC81x family.

Microcontrollers Part Context

This component belongs to Analog Devices' MicroConverter family, which merges precision analog functions with digital control. The ADUC814 specifically targets applications needing small package footprints. It utilizes standard CMOS processes adapted for mixed-signal integration, distinguishing it from pure MCU or ADC-only devices.

Microcontrollers Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Consult the manufacturer's ordering guide for current equivalents or updated revisions of the ADuC814 series.
