Overview

The ATMEGA1284RFR2-ZFR is a high-performance 8-bit AVR microcontroller integrated with a 2.4GHz ISM band wireless transceiver. It combines 128kB of Flash memory with a hardware-accelerated IEEE 802.15.4 engine, enabling low-power wireless networking for Zigbee and other WPAN protocols.

Why Choose This Part

The device features Advanced Hardware assisted Reduced Power Consumption (RPC) which maintains high performance while drawing only 10.1mA at 16MHz. Its integrated radio achieves a high sensitivity of -100dBm, allowing for extended range without external LNA components.

Applications

Zigbee Home Automation
Ideal for battery-powered light switches, thermostats, and occupancy sensors requiring secure mesh networking.
Industrial Monitoring
Provides reliable wireless data transmission in noisy environments using hardware-assisted MAC functions like auto-retry and CRC computation.
Smart Energy Systems
Supports Multiple PAN Address Filtering for complex grid monitoring and meter reading applications.
