Overview
The AVR32DD32T-I/RXB is an 8-bit microcontroller from the AVR® DD Family, featuring a 32 KB Flash memory, 4 KB SRAM, and 256 bytes of EEPROM. It operates at clock speeds up to 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC with 23 channels, a 10-bit DAC, two USARTs, SPI, TWI/I2C, and four timers (one TCA, three TCB). It utilizes a 32-pin VQFN package and supports industrial temperature ranges.
Feature Summary
- Features Multi-Voltage I/O (MVIO) on Port C for flexible voltage level interfacing
- Includes Configurable Custom Logic (CCL) with programmable Look-up Tables for hardware logic implementation
- Supports simultaneous host and client operation on the TWI/I2C interface
Applications
- Industrial control systems requiring multi-voltage I/O capabilities
- Smart home appliances and IoT devices
- Automotive applications within the industrial temperature range
Procurement Notes
Verify the specific ordering suffix 'RXB' corresponds to the 32-pin VQFN package and 'T' indicates tape and reel packaging. Confirm the 'I' suffix matches the required -40°C to +85°C industrial temperature rating. Ensure compatibility with existing design footprints for the 32-VQFN(5x5) form factor before finalizing procurement.
Selection Notes
Select this component when 32 KB of program memory and 4 KB of RAM are sufficient for the application requirements. Consider the 24 MHz maximum frequency and the availability of 23 ADC channels if analog signal processing is needed. Verify that the 32-pin VQFN package fits the mechanical constraints of the target PCB design.
Part Context
This part belongs to the AVR® DD Family, which offers vertical migration without code modification across different pin counts and memory sizes. It shares architectural similarities with other AVR DD devices like the AVR32DD28 and AVR64DD32, allowing for scalable design transitions within the same ecosystem.

FAQ
What is the function of the MVIO feature in this MCU?
Multi-Voltage I/O (MVIO) allows Port C pins to operate at different voltage levels than the core supply voltage, enabling direct interfacing with peripherals operating at different voltages.
Does the TWI interface support dual mode operation?
Yes, the TWI/I2C interface can operate simultaneously as both a host and a client on different pins.
