Overview

The AVR32DU14-I/SL is a Microchip AVR 8-bit microcontroller with 32 KB of Flash, 4 KB of SRAM, and integrated USB support. It is aimed at compact embedded designs that need a small MCU with mixed peripheral support, including UART, SPI, TWI, and a 10-bit ADC.

Why Choose This Part

This part combines a small memory footprint with a useful mix of on-chip peripherals, which can reduce external component count in simple designs. The integrated USB, ADC, and serial interfaces make it practical for compact controller boards and USB-connected peripherals. As an AVR device, it also fits well into established Microchip AVR development workflows.

Applications

USB-enabled embedded controllers
Good for small devices that need a direct USB interface for configuration, data transfer, or HID-style connectivity.
Sensor interface nodes
Useful for reading analog sensors and communicating over UART, SPI, or TWI in compact control systems.
Prototyping and education
Fits simple embedded exercises, lab work, and breadboard-friendly firmware development with AVR tools.
Simple control and status devices
Suitable for low-complexity products such as panel controllers, indicator modules, and interface adapters.

Getting Started

Use Microchip Studio or MPLAB X IDE with the appropriate AVR toolchain and a supported programmer/debugger such as Atmel-ICE. For USB projects, start from Microchip example code or board support packages that match the AVR DU family, then verify clock, USB, and pin-mux configuration early in bring-up. If you are prototyping, check for a matching development board or reference design so you can validate power, reset, and USB enumeration before moving to a custom PCB.
