AVR32DD32T-E/PT

Overview

The AVR32DD32T-E/PT is an 8-bit microcontroller from the AVR DD family, featuring a 64 KB Flash memory, 8 KB SRAM, and 256 bytes of EEPROM. It utilizes an AVR CPU with a hardware multiplier, operating at clock speeds up to 24 MHz across a supply voltage range of 1.8V to 5.5V. The device includes a 12-bit differential ADC with 23 channels, a 10-bit DAC, and multiple communication interfaces including USART, SPI, and TWI. It is housed in a TQFP-32 package and supports extended industrial temperature ranges.

Feature Summary

• Multi-Voltage I/O (MVIO) capability on PORTC for interfacing with different power domains without external level shifters
• Configurable Custom Logic (CCL) with four Look-up Tables for independent peripheral signaling and logic implementation
• Event System (EVSYS) enabling low-latency, CPU-independent inter-peripheral communication
• Integrated Zero-Cross Detector (ZCD) and Analog Comparator for precise signal monitoring and control

Applications

• Industrial control systems requiring multi-voltage domain integration
• Smart home appliances with real-time processing needs
• IoT terminal nodes utilizing low-power sleep modes
• Power control applications leveraging optimized Timer/Counter Type D

Procurement Notes

Verify the 'E' suffix indicates the extended temperature range (-40°C to +125°C) and the 'T' suffix denotes tape and reel packaging. Confirm that the specific pinout matches the TQFP-32 footprint requirements for your PCB design. Ensure compatibility with the UPDI programming interface for development and debugging workflows.

Selection Notes

Select this component when 64 KB of program memory and 8 KB of RAM are required within a 32-pin form factor. The extended temperature rating makes it suitable for harsh environments compared to industrial-only variants. Consider the MVIO feature if the design involves mixed-voltage sensors or actuators connected directly to PORTC.

Part Context

This part belongs to the AVR DD family, which emphasizes vertical migration compatibility across pin counts and memory sizes. It shares architectural similarities with other AVR DD devices like the AVR64DD28, allowing for code reuse during design iterations. The family integrates intelligent analog features and advanced digital peripherals to reduce system latency.

Replacement Considerations

AVR64DD32T-I/PT offers identical functionality but operates within the industrial temperature range (-40°C to +85°C). AVR32DD32T-E/PT provides the same package and temperature rating but with reduced memory capacity (32 KB Flash, 4 KB SRAM).
