AVR64DA28-E/SO

Overview

The AVR64DA28-E/SO is an 8-bit microcontroller from the AVR DA(S) family, featuring a 28-pin SOIC package. It operates at a maximum frequency of 24 MHz and includes 64 KB of Flash memory, 8 KB of SRAM, and 512 B of EEPROM. The device supports a supply voltage range of 1.8 V to 5.5 V and functions within an extended temperature range of -40°C to +125°C. Key peripherals include a 12-bit ADC with 10 channels, a 10-bit DAC, three analog comparators, up to six USARTs, two SPI interfaces, and two TWI/I2C controllers.

Feature Summary

• AVR CPU with hardware multiplier running at up to 24 MHz
• Integrated Event System for CPU-independent inter-peripheral signaling
• Configurable Custom Logic (CCL) with programmable Look-up Tables
• Peripheral Touch Controller (PTC) supporting capacitive touch applications

Applications

• Real-time control systems
• Sensor nodes
• Secondary safety monitoring devices
• Closed-loop control designs

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and 'SO' indicates the SOIC package style. Confirm the specific revision level of datasheet DS40002233C 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 DA(S) family is required without code modification. It is suitable for designs needing multiple communication interfaces like USART and TWI in a compact 28-pin form factor. Consider the extended temperature rating if operating in harsh environments.

Part Context

This device belongs to the AVR DA(S) family, which offers pin and feature compatibility across different pin counts and memory sizes. The AVR64DA28 variant provides a balance of processing power and peripheral richness in a small footprint, allowing horizontal migration to lower pin count devices or vertical scaling to higher memory variants.
