ATMEGA128RFR2-ZU

ATMEGA128RFR2-ZU Description

The ATMEGA128RFR2-ZU from Microchip Technology is a highly integrated TxRx + MCU solution combining an 802.15.4 RF transceiver with an 8-bit AVR microcontroller. Designed for low-power wireless applications, it operates in the 2.4GHz ISM band with a maximum data rate of 2Mbps, supporting Zigbee® and other IEEE 802.15.4-based protocols. The device features 128kB Flash, 4kB EEPROM, and 16kB SRAM, providing ample memory for embedded applications. Its 1.8V–3.6V supply range and ultra-low power consumption (5mA–12.5mA RX, 8mA–14.5mA TX) make it ideal for battery-operated IoT devices. Packaged in a 64-VFQFN form factor, it is suited for surface-mount designs in space-constrained environments.
