ATMEGA128RFR in ATmega Family
The ATmega128RFR sub-family, manufactured by Microchip Technology, integrates a high-performance 8-bit AVR microcontroller with a 2.4 GHz IEEE 802.15.4 compliant radio transceiver on a single SoC. Designed for low-power wireless communication, these devices offer a compact footprint for space-constrained applications. They provide engineers with a robust solution for localized data transmission, utilizing a single-chip architecture to reduce bill-of-materials costs while maintaining the familiar AVR instruction set and toolchain ecosystem.
Variants in This Sub-Family
Variants within the ATmega128RFR sub-family typically differ in flash memory density, peripheral sets, and operating temperature ranges. While the core RF performance remains consistent, models like the RFR2 series offer improved power efficiency and reduced current consumption in deep-sleep modes compared to first-generation parts. Some variants also provide different pin counts and package sizes to balance I/O requirements against physical space constraints in portable designs.
