MCHPATMEGA256RFR2-ZU
Overview
The ATMEGA256RFR2-ZU is a low-power 8-bit AVR microcontroller featuring an integrated 2.4GHz ISM band transceiver designed for IEEE 802.15.4 and Zigbee applications. It combines 256KB of flash memory with 32KB of RAM, providing a single-chip solution for wireless sensor networks and mesh networking.
Why Choose This Part
This SoC simplifies RF design by integrating the transceiver and microcontroller into a single 42-pin package, significantly reducing PCB footprint. It offers exceptional power efficiency with sleep currents as low as 0.6 microamps and features a preassigned MAC address for simplified device commissioning.
Applications
Getting Started
Engineers can develop with this part using the Atmel Studio (now Microchip Studio) IDE and the AVR GCC toolchain. Practical implementation is supported by the Microchip BitCloud Zigbee PRO stack and Atmel Lightweight Mesh software libraries.
