ATMEGA64RFR2-ZFR

RF Transceiver ICS Overview

The ATMEGA64RFR2-ZFR is an integrated system-on-chip combining a 2.4 GHz IEEE 802.15.4/Zigbee radio transceiver with an 8-bit AVR microcontroller core. It features 64 kB of flash memory, 2 kB EEPROM, and 8 kB SRAM. The device supports DSSS and O-QPSK modulation at data rates up to 2 Mbps, delivering 3.5 dBm output power and -100 dBm sensitivity. Operating voltage ranges from 1.8 V to 3.6 V, with receive current between 5 mA and 12.5 mA, and transmit current between 8 mA and 14.5 mA. It utilizes a 64-pin VFQFN package with an exposed pad.

RF Transceiver ICS Feature Summary

• Integrates a complete 802.15.4 Zigbee transceiver with an 8-bit AVR RISC microcontroller core for true system-on-chip functionality.
• Delivers high processing efficiency with throughput approaching 1 MIPS per MHz for optimal power consumption versus speed.
• Supports multiple serial communication interfaces including I²C, JTAG, SPI, and USART alongside extensive GPIO availability.

RF Transceiver ICS Applications

• Wireless sensor networks requiring low-power connectivity
• Zigbee-based home automation and smart lighting systems
• Industrial monitoring and control applications

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'ZFR' indicates tape-and-reel packaging when sourcing components. Confirm that the operating temperature range aligns with industrial requirements, as some variants may differ in thermal specifications. Ensure compatibility with Microchip development tools such as Atmel Studio or MPLAB X IDE for programming and debugging. Cross-reference the manufacturer part number against official distributor catalogs to avoid confusion with similar packages like the ZU variant.

RF Transceiver ICS Selection Notes

Select this component for designs requiring integrated RF and MCU capabilities without external transceivers. Consider the 64-VFQFN package constraints for PCB layout and thermal management. Evaluate the 16 MHz maximum clock frequency against application timing needs. Verify that the 35 available GPIO pins meet interface requirements. Assess power supply stability within the 1.8 V to 3.6 V range to ensure reliable operation across the specified temperature spectrum.
