ATMEGA256RFR in ATmega Family

The ATMEGA256RFR2 family from Microchip Technology is a high-performance series of 8-bit AVR microcontrollers featuring an integrated 2.4 GHz IEEE 802.15.4 compliant radio transceiver. These System-on-Chip (SoC) solutions combine 256KB of flash memory with advanced wireless capabilities, designed specifically for low-power mesh networking. By merging a proven 8-bit MCU core with a high-sensitivity radio, this family enables compact, cost-effective wireless nodes for Zigbee, 6LoWPAN, and proprietary ISM band applications requiring significant local storage for application code.

Variants in This Sub-Family

Variants within the ATMEGA256RFR2 family primarily differ based on their packaging options and environmental qualification. The standard ATMEGA256RFR2-ZU is provided in a 64-pad VFQFN tray for high-volume manufacturing, while the -ZUR suffix denotes the same component delivered in tape-and-reel format for automated pick-and-place assembly. All family members share the same electrical characteristics, including 256KB flash, 32KB RAM, and the high-performance AVR core.
