ADUC7021BCPZ62

Overview

The ADuC7021BCPZ62 is a precision analog microcontroller featuring an ARM7TDMI core, 62 kB Flash/EE memory, and 8 kB SRAM. It integrates a 1 MSPS, 12-bit ADC with up to 16 channels and two 12-bit buffered DACs. Operating at 41.78 MHz with 120 mW typical power dissipation, it supports 2.7 V to 3.6 V supplies within the −40°C to +125°C industrial temperature range.

Feature Summary

• Integrates a 1 MSPS, 12-bit multichannel ADC supporting single-ended and differential modes.
• Includes two 12-bit buffered voltage output DACs with programmable ranges.
• Features an ARM7TDMI RISC core with on-chip oscillator, PLL, and serial interfaces.
• Provides nonvolatile Flash/EE memory for in-circuit reprogrammability.

Applications

• Industrial control and automation systems
• Smart sensors and precision instrumentation
• Base station systems and optical networking

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with required development tools such as the QuickStart system or JTAG debuggers before procurement.

Selection Notes

Select this component when a high-performance MCU requires integrated precision analog acquisition. The combination of a 1 MSPS ADC and dual DACs reduces external component count. Verify that the available GPIO and serial interface resources meet the system requirements.

Part Context

This device belongs to the Analog Devices MicroConverter family, which combines digital processing with analog signal conditioning. The ADuC7021 variant specifically includes dual DACs, distinguishing it from models like the ADuC7022 which lack DAC outputs but offer additional ADC channels.

Replacement Considerations

The ADuC7022BCPZ62 serves as a functional substitute within the same series, offering identical processing capabilities but without DAC outputs.
