Overview
The AVR32DD32-I/RXB is an 8-bit microcontroller from the AVR DD family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 32 KB of in-system programmable Flash, 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 an industrial temperature range of -40°C to +85°C. It is housed in a 32-pin VQFN package (RXB suffix) and provides up to 26 general-purpose I/O pins.
Feature Summary
- AVR CPU running at up to 24 MHz with single-cycle I/O access
- Integrated Event System for inter-peripheral signaling
- Multi-Voltage I/O (MVIO) support on PORTC
- Configurable Custom Logic (CCL) with four Look-up Tables
Applications
- Industrial control systems
- Consumer electronics
- Smart home appliances
- Battery-powered devices
Procurement Notes
Verify the specific ordering suffixes against official Microchip documentation to ensure correct package type, temperature rating, and carrier configuration. Confirm that the RXB suffix corresponds to the required 32-pin VQFN form factor and that the I suffix matches the intended industrial operating temperature range before finalizing procurement.
Selection Notes
Select this component when pin compatibility with other AVR DD family members is required for vertical migration. Consider the 32 KB Flash and 4 KB SRAM limits for code size and data storage needs. Ensure the design accommodates the 1.8 V to 5.5 V supply range and utilizes the UPDI interface for programming and debugging.
Part Context
This part belongs to the AVR DD family, which emphasizes low power consumption and advanced peripheral integration. It shares architectural similarities with the AVR16 and AVR64 variants, allowing for flexible memory scaling while maintaining pin compatibility across the series.
