Overview
The AVR32DD32-E/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 1.8V to 5.5V. The device includes a 12-bit ADC, 10-bit DAC, USART, SPI, TWI/I2C interfaces, and Multi-Voltage I/O (MVIO). It is housed in a 32-pin VQFN package and supports an extended temperature range of -40°C to +125°C.
Feature Summary
- Multi-Voltage I/O (MVIO) capability on PORT C for level shifting between different power domains
- Configurable Custom Logic (CCL) with four Look-Up Tables for hardware logic implementation
- Event System (EVSYS) enabling CPU-independent peripheral signaling
- Single-pin Unified Program and Debug Interface (UPDI)
Applications
- Industrial control systems requiring multi-voltage operation
- Smart home appliances with mixed-signal requirements
- IoT devices needing low-power sleep modes and efficient I/O management
Procurement Notes
Verify the specific ordering suffix 'RXB' corresponds to the 32-pin VQFN package and 'E' indicates the extended temperature range (-40°C to +125°C). Confirm that the datasheet DS40002315 applies to this variant within the AVR DD family. Ensure compatibility with UPDI programming tools for development.
Selection Notes
Select this component when vertical migration within the AVR DD family is required without code modification. It is suitable for designs needing MVIO functionality to interface with 5V peripherals while operating at lower voltages. Consider the 32KB Flash and 4KB RAM limits for application complexity.
Part Context
This part belongs to the AVR DD family, which offers pin-and-feature compatible migration across 16KB, 32KB, and 64KB Flash variants. The 'AVR32DD32' designation indicates 32KB Flash and 32 pins. The 'E' suffix denotes extended temperature performance, distinguishing it from industrial grade parts.
Replacement Considerations
Compatible substitutes include other AVR32DD32 variants with different packages (e.g., TQFP or SSOP) or temperature grades (e.g., Industrial '-I'). Ensure the replacement maintains the same memory size and peripheral set for direct pin-to-pin compatibility.
