AVR16DD20T-I/REB

Overview

The AVR16DD20T-I/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 (3x3 mm) and supports industrial temperature ranges (-40°C to +85°C).

Feature Summary

• Features Multi-Voltage I/O (MVIO) on PORTC for flexible voltage level interfacing.
• Includes intelligent analog peripherals such as a 12-bit differential ADC and Zero-Cross Detector.
• Supports CPU-independent inter-peripheral signaling via the Event System.

Applications

• Low-power embedded control systems requiring MVIO flexibility.
• Applications utilizing analog signal processing with integrated ADC and DAC.
• Industrial monitoring devices operating within standard industrial temperature ranges.

Procurement Notes

Verify the specific ordering suffix 'T/REB' corresponds to the Tape & Reel carrier type and Industrial temperature grade. Confirm that the component matches the AVR DD family specifications regarding pinout and peripheral availability. Ensure compatibility with existing design constraints before finalizing procurement orders.

Selection Notes

Select this model when 16 KB of Flash and 2 KB of RAM are sufficient for the application logic. Consider the VQFN-20 package dimensions for PCB layout constraints. Verify that the required number of I/O pins and analog channels aligns with the device's 16 available I/O and 13 ADC channel capabilities.

Part Context

This component belongs to the AVR DD family, which emphasizes low power consumption and advanced analog features. It shares architectural similarities with other members like the AVR32DD20 and AVR64DD20, allowing for potential vertical migration without code modification if higher memory or pin counts are required in future designs.
