Overview

The AVR16DU14-I/SL is an 8-bit AVR microcontroller featuring 16KB of Flash and integrated Full-Speed USB functionality in a compact 14-pin SOIC package. Part of the AVR DU family, it operates at speeds up to 24MHz and includes specialized peripherals like Configurable Custom Logic (CCL) and an Event System to reduce CPU overhead.

Why Choose This Part

This MCU eliminates the need for external crystals by utilizing a high-precision internal oscillator with auto-tuning for USB clock recovery. Its single-pin UPDI interface simplifies programming and debugging, while the Event System allows peripherals to communicate directly, ensuring low-latency responses even when the CPU is busy.

Applications

USB Peripheral Bridges
Creating small USB-to-UART or USB-to-SPI bridges for legacy hardware or custom interfaces.
PC Input Devices
Implementing custom HID devices such as specialized keyboards, game controllers, or macro pads.
Industrial USB Sensors
Developing compact sensor nodes that report data directly to a host computer via USB without external interface ICs.

Getting Started

Develop firmware using MPLAB X IDE or Microchip Studio with the XC8 compiler and the AVR DU Family Pack. For hardware evaluation, use the AVR16DU14 Curiosity Nano evaluation kit or program the chip directly via a PICkit 5 or MPLAB Snap debugger using the UPDI pin.

Also Consider

CH340G WCH - A dedicated USB-to-Serial bridge IC if full microcontroller programmability is not required.
