ATMEGA256RFR2-ZFR

RF Transceiver ICS Overview

The ATMEGA256RFR2-ZFR is a System on Chip integrating an 8-bit AVR RISC microcontroller with a 2.4 GHz IEEE 802.15.4-compliant radio transceiver. It features 256 KB of Flash memory, 32 KB of SRAM, and operates within a voltage range of 1.8 V to 3.6 V. The device supports data rates up to 2 Mbps and includes hardware-assisted multiple PAN address filtering. Packaged in a 64-pin QFN, it is designed for industrial temperature ranges up to +125°C.

RF Transceiver ICS Feature Summary

• Integrates an 8-bit AVR RISC microcontroller core with a dedicated IEEE 802.15.4 radio transceiver for unified processing and communication.
• Supports global 2.4 GHz ISM band operation with DSSS and O-QPSK modulation schemes for reliable wireless connectivity.
• Includes hardware-assisted multiple PAN address filtering to reduce processor load and improve network efficiency.

RF Transceiver ICS Applications

• ZigBee and ZigBee RF4CE protocol implementations
• 6LoWPAN sensor networks
• High data rate ISM band applications

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'ZFR' indicates tape and reel packaging when ordering. Confirm that the industrial temperature grade (+125°C) matches your environmental requirements. Ensure the 64-VFQFN package dimensions align with your PCB footprint design. Cross-reference the datasheet revision date to ensure compatibility with current development tools.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and RF solution is required for 2.4 GHz wireless applications. It is suitable for designs needing hardware acceleration for network protocols like ZigBee. Consider the 8-bit architecture and available peripheral interfaces such as SPI, I2C, and USART for system integration.

RF Transceiver ICS Part Context

This part belongs to the ATmega256RFR2 family, which combines Microchip's AVR microcontrollers with integrated RF capabilities. The family targets low-power wireless sensor networks and IoT devices requiring robust 2.4 GHz communication without external transceivers.

RF Transceiver ICS Replacement Considerations

Public confirmed substitute part numbers include ATMEGA256RFR2-ZU (tray version) and ATMEGA256RFR2-ZUR (reel version). These variants share identical electrical and functional specifications but differ in packaging format.
