AVR32DD28T-E/SO

Overview

The AVR32DD28T-E/SO is an 8-bit microcontroller from the AVR DD family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 32 KB of Flash memory, 4 KB of SRAM, and 256 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an extended temperature range of -40°C to +125°C. It is housed in a 28-pin SOIC package.

Feature Summary

• Multi-Voltage I/O (MVIO) on PORT C enables bidirectional communication across different power domains without external level shifters.
• Configurable Custom Logic (CCL) provides four programmable Look-up Tables for flexible digital logic implementation.
• Event System allows CPU-independent inter-peripheral signaling to reduce system latency.

Applications

• Industrial control systems requiring robust noise immunity
• Smart home appliances with multiple power domains
• Automotive applications meeting ISO 26262 safety standards

Procurement Notes

Verify the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C). Confirm the 'SO' suffix matches the required SOIC-28 package dimensions. Ensure the 'T' suffix aligns with tape-and-reel handling requirements for automated assembly processes.

Selection Notes

Select this model when 32 KB of program memory and 4 KB of RAM are sufficient for the application. Choose the SOIC package for through-hole or standard surface-mount compatibility. Verify that the 28-pin count meets the specific I/O requirements compared to other pin counts in the AVR DD family.

Part Context

This component belongs to the AVR DD family, which offers vertical migration capabilities without code modification. Devices within this family share fully compatible pins and features, allowing designers to scale memory sizes while maintaining software integrity across the product line.

Replacement Considerations

AVR32DD28T-E/SS: Identical electrical specifications and memory configuration; differs only in SSOP-28 packaging instead of SOIC-28.
