Descriptions:

The ATMEGA16U2-MU is a low-power, high-performance microcontroller with built-in USB functionality. It is commonly used in USB-to-serial converter applications, such as in Arduino boards (e.g., Arduino Uno R3). Its USB controller allows direct communication with a host PC without requiring additional components.

Features:

  • USB 2.0 Full-Speed Device with embedded PHY
  • Low Power Consumption (Active & Idle modes)
  • On-Chip Bootloader for easy firmware updates
  • Hardware-Based USB FIFO for efficient data transfer
  • Programmable Watchdog Timer
  • Power-On Reset (POR) & Brown-Out Detection (BOD)
  • Industrial Temperature Range (-40°C to +85°C)

This microcontroller is ideal for embedded USB applications, including HID (Human Interface Device) and CDC (Communication Device Class) implementations.
