ATMEGA8U2-AU
Discontinued
The ATMEGA8U2-AU is a low-power 8-bit AVR microcontroller with built-in USB support. Based on the AVR enhanced RISC architecture, it executes most instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz. It's commonly used as a USB-to-serial bridge on Arduino boards.
This is the TQFP-32 surface-mount package variant, suitable for custom PCB designs and replacement parts.
Key Features
- AVR RISC Architecture – Single-cycle instruction execution for efficient processing
