Overview
The AVR32DA32T-I/PT is an 8-bit microcontroller from the AVR DA family, featuring a 32 KB Flash memory, 4 KB SRAM, and 512B EEPROM. It operates at a maximum frequency of 24 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 12-bit ADC, three analog comparators, two zero-cross detectors, a 10-bit DAC, six UARTs, two SPI interfaces, and TWI/I2C. It utilizes a TQFP-32 package and supports industrial temperature ranges.
Feature Summary
- Integrates intelligent analog features including a 12-bit differential ADC, three analog comparators, and a 10-bit DAC for signal conditioning.
- Supports secure firmware upgrades through Program and Debug Interface Disable (PDID) mechanisms.
- Features a Peripheral Touch Controller (PTC) with Driven Shield+ technology for capacitive touch applications.
- Includes an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL).
Applications
- Capacitive touch button, slider, wheel, and 2D surface implementations
- Secure firmware upgrade systems requiring code authentication
- Power control applications utilizing Timer/Counter type D
- Industrial communication nodes using multiple USART and SPI interfaces
Procurement Notes
Verify the ordering suffix 'T' indicates tape and reel packaging. Confirm the '-I' suffix corresponds to the industrial temperature range of -40°C to +85°C. Ensure the 'PT' suffix matches the TQFP-32 package requirement. Cross-reference the datasheet DS40002228C for specific pinout and electrical characteristics.
Selection Notes
Select this component for designs requiring vertical migration within the AVR DA(S) family without code modification. Consider the 24 MHz operating speed and multi-voltage I/O capabilities for flexible system integration. Evaluate the available peripheral count against application requirements for timers, communication interfaces, and analog channels.
Part Context
This part belongs to the AVR32DA28/32/48(S) series, which shares a common architecture and instruction set. Devices in this family offer horizontal and vertical migration paths, allowing designers to scale pin counts and memory sizes while maintaining software compatibility across the product line.

FAQ
What is the maximum operating frequency of the AVR32DA32T-I/PT?
The device runs at up to 24 MHz.
Does the AVR32DA32T-I/PT support capacitive touch sensing?
Yes, it includes a Peripheral Touch Controller (PTC) with Driven Shield+ and Boost Mode technologies supporting up to 32 self-capacitance and 256 mutual capacitance channels.
How does the PDID feature enhance security?
PDID prevents access to the reprogrammable Flash memory over the UPDI after activation, protecting against remote attacks and ensuring only authenticated software updates can be applied via the Boot Code section.
