AVR32DU in AVR DA/DB/DD/DU Family
The AVR32DU sub-family, manufactured by Microchip Technology, is a high-performance 8-bit microcontroller line built on the AVR architecture with integrated USB connectivity. These devices are designed to bridge the gap between traditional 8-bit simplicity and modern interface requirements, featuring Core Independent Peripherals (CIPs) and a sophisticated Event System. They are primarily used in applications requiring cost-effective USB communication, reliable 5V operation, and reduced CPU overhead through hardware-based signal processing and timing tasks.
Variants in This Sub-Family
| Part Number | Difference | Stock |
|---|---|---|
| AVR32DU28-I/STX (Microchip Technology) | 28-I/STX | 602 |
| AVR32DU14-I/SL (Microchip Technology) | 14-I/SL | 753 |
| AVR32DU28-I/SS (Microchip Technology) | 28-I/SS | 484 |

The AVR32DU sub-family variants primarily differ in pin count and package type, ranging from 14-pin SOIC to 32-pin VQFN and TQFP configurations. While all current members share a 32KB Flash and 4KB SRAM memory footprint, the available I/O pins and specific number of ADC channels vary based on the physical package size, allowing engineers to scale the design based on board space constraints.
