AVR32DD28T-I/SO

Overview

The AVR32DD28T-I/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 Multi-Voltage I/O (MVIO). Key peripherals include a 12-bit ADC, 10-bit DAC, Zero-Cross Detector, two USARTs, SPI, and TWI interfaces.

Feature Summary

• Multi-Voltage I/O (MVIO) capability on PORT C enables true level-shifted bidirectional communication across different power domains without external converters.
• Integrated intelligent analog features including a 12-bit differential ADC, 10-bit DAC, and Zero-Cross Detector for precise signal processing.
• Advanced digital peripherals such as Configurable Custom Logic (CCL) and Event System reduce system latency and CPU load.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, temperature range, and carrier format. Ensure compatibility with existing design constraints before procurement.

Selection Notes

Select this component for designs requiring vertical migration within the AVR DD family. It offers pin and feature compatibility with other devices in the series, allowing code reuse while adjusting memory or pin counts.

Part Context

This part belongs to the AVR DD family of 8-bit microcontrollers. It shares architectural similarities with AVR16DD and AVR64DD variants, differing primarily in memory size and pin count configurations.

Replacement Considerations

AVR32DD20T-I/SO and AVR32DD32T-I/PT are compatible alternatives within the same family offering similar functionality with different pin counts or packages.
