AVR16DD28-E/SO

Overview

The AVR16DD28-E/SO is an 8-bit microcontroller from the AVR DD family, featuring a 16 KB Flash memory, 2 KB SRAM, and 256 bytes of EEPROM. It operates at clock speeds up to 24 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 12-bit ADC with 19 channels, a 10-bit DAC, two USARTs, SPI, and TWI interfaces. It utilizes Multi-Voltage I/O (MVIO) for flexible interfacing across different power domains.

Feature Summary

Multi-Voltage I/O (MVIO) support enables direct bidirectional communication between devices operating on different power domains without external level shifters.
Integrated intelligent analog peripherals include a 12-bit differential ADC, 10-bit DAC, Analog Comparator, and Zero-Cross Detector for precise signal processing.
Advanced digital peripherals such as Configurable Custom Logic (CCL) and Event System (EVSYS) reduce CPU load by enabling hardware-based inter-peripheral signaling.

Applications

Industrial control systems requiring robust noise immunity and multi-voltage domain interfacing
Smart home appliances utilizing low-power operation and integrated sensing capabilities
IoT nodes leveraging MVIO for seamless connectivity with various peripheral sensors

Procurement Notes

Verify that the ordering suffix 'SO' corresponds to the SOIC package style and 'E' indicates the extended temperature range (-40°C to +125°C). Confirm the specific datasheet revision matches your design requirements. Ensure compatibility with UPDI programming tools for development and debugging.

Selection Notes

Select this component when vertical migration within the AVR DD family is required without code modification. Choose this part if the application demands high pin count flexibility with 28 pins while maintaining full feature compatibility with other family members. Consider the extended temperature rating for harsh environments.

Part Context

This device belongs to the AVR DD family, which offers vertical migration capabilities across 14, 20, 28, and 32-pin variants. The family shares identical pinouts and features, allowing designers to scale solutions easily. The AVR16DD28 variant specifically provides a balance of memory and I/O resources for mid-range applications.
