AVR64DD28-E/SO

Overview

The AVR64DD28-E/SO is an 8-bit microcontroller from the AVR DD family, utilizing an AVR CPU with a hardware multiplier. It features 64 KB of in-system self-programmable Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. The device operates at clock speeds up to 24 MHz within a supply voltage range of 1.8V to 5.5V. It includes a 12-bit differential ADC, a 10-bit DAC, three analog comparators, and multi-voltage I/O capabilities. The component is housed in a 28-pin SOIC package and supports an extended operating temperature range.

Feature Summary

• Multi-Voltage I/O (MVIO) support enables bidirectional communication across different power domains without external level shifters.
• Configurable Custom Logic (CCL) provides four programmable Look-up Tables for custom digital logic implementation.
• Event System allows for CPU-independent inter-peripheral signaling to reduce system latency.
• Integrated intelligent analog peripherals include a 12-bit ADC, 10-bit DAC, and Zero-Cross Detector.

Applications

• Industrial control systems requiring real-time processing
• Smart home appliances with multiple voltage domains
• Internet of Things (IoT) sensor nodes
• Automotive applications meeting functional safety standards

Procurement Notes

Verify the ordering suffix 'E' confirms the extended temperature rating (-40°C to +125°C). Confirm the 'SO' suffix indicates the SOIC package style. Ensure the specific part number matches the required pin count and memory configuration before finalizing procurement orders.

Selection Notes

Select this model when 64 KB of program memory and 8 KB of RAM are required. Choose the extended temperature variant for environments exceeding standard industrial limits. Verify that the 28-pin SOIC footprint aligns with the target PCB design constraints.

Part Context
