AVR16DD20-E/REB

Overview

The AVR16DD20-E/REB is an 8-bit microcontroller from the AVR DD family, featuring a 16 KB Flash program memory and 2 KB SRAM. It operates at a maximum clock frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC with 13 channels, a 10-bit DAC, two USARTs, SPI, and TWI interfaces. It utilizes a VQFN-20 package and supports an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Supports Multi-Voltage I/O (MVIO) on PORTC for flexible voltage level interfacing
• Integrates an Event System for CPU-independent peripheral signaling
• Includes Configurable Custom Logic (CCL) with Look-up Tables for custom logic implementation

Applications

• Industrial control systems requiring robust analog signal processing
• Battery-powered devices utilizing low-power sleep modes
• Smart sensors integrating ADC and DAC capabilities

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding pin count and memory size before finalizing procurement orders.

Selection Notes

Select this component when 16 KB of Flash and 2 KB of RAM are sufficient for application requirements. Consider the extended temperature rating (-40°C to +125°C) for harsh environments. Verify that the VQFN-20 package fits the PCB layout constraints.

Part Context

This part belongs to the AVR DD family, which offers vertical migration compatibility within the series. It shares architectural similarities with higher-memory variants like the AVR32DD20 and AVR64DD20, allowing for potential code reuse across different memory configurations.

Replacement Considerations

AVR16DD20T-I/REB serves as a direct substitute with identical specifications but differs in the operating temperature range, supporting Industrial (-40°C to +85°C) instead of Extended.
