Overview

The ATMEGA128RFA1-ZUR00 is a single-chip solution combining an 8-bit AVR microcontroller with a high-performance 2.4GHz IEEE 802.15.4 compliant radio transceiver. It integrates 128kB of Flash and 16kB of SRAM, specifically designed to reduce component count and power consumption in wireless sensor network applications.

Why Choose This Part

This SoC eliminates the need for an external SPI interface between the MCU and radio, reducing latency and PCB footprint. Its 3.5dBm output power and -100dBm sensitivity provide a robust link budget for 802.15.4 communications while maintaining a low active current of 4.1mA for the CPU.

Applications

Zigbee Networking
Ideal for building mesh networks in smart home systems, including lighting and climate control.
Industrial Monitoring
Utilizing the -100dBm sensitivity for reliable wireless data collection in noisy RF environments.
6LoWPAN Nodes
Implementing IPv6 over low-power wireless personal area networks for IoT edge devices.
Energy Management
Low-power modes and integrated radio make it suitable for battery-operated smart meters and energy sensors.
