Overview

The ATMEGA3209-AF is a high-performance, low-power 8-bit AVR microcontroller featuring the megaAVR 0-series architecture. It operates at speeds up to 20MHz with 32KB of Flash, 6KB of SRAM, and 256 bytes of EEPROM in a 48-pin TQFP package.

Why Choose This Part

The inclusion of the Event System and CCL allows for complex, high-speed logic tasks to be handled independently of the CPU core. Its 6KB of SRAM is unusually high for an 8-bit MCU of this Flash size, providing extra headroom for communication buffers and RTOS implementations.

Applications

Industrial Sensor Nodes
Utilizes the 10-bit ADC and low-power sleep modes for remote monitoring applications.
Home Automation
Employs the Event System and Configurable Custom Logic (CCL) for deterministic peripheral responses without CPU intervention.
Battery-Powered Handhelds
Takes advantage of the 0.1 uA power-down current and SleepWalking features to extend battery life.

Getting Started

Development is supported by the Microchip Curiosity Nano (AC164160) and the MPLAB X or Microchip Studio IDEs. Programming and debugging are performed via the single-pin Unified Program Debug Interface (UPDI).
