RF Single-Chip Solutions

The IEEE 802.15.4-compliant Atmel single-chip combines the industry's leading AVR® microcontroller and a best-in-class 2.4GHz RF transceiver to deliver the industry's best single-chip design.

The ATmega128RFA1 is the leading device in this new single-chip family. The combination of low current consumption in all operating modes, a degradation-free supply voltage range down to 1.8V and fastest wake-up time from SLEEP mode to active modes make the ATmega128RFA1 to the most power efficient device in the market, and yet another uncompromised product by Atmel. Various power-down modes including the wake-on-radio feature enable further power optimizations, like keeping the RF transceiver active while the microcontroller sleeps.

Boost your overall system performance

The radio interface offers a unique hardware feature set to boost the overall system performance and to support a great variety of IEEE 802.15.4-compliant applications. The radio link reliability is additionally improved when using the antenna diversity feature which automatically selects the best from two antennas for each incoming frame. The device supports the control of external power amplifiers for range extension. High data rate modes up to 2 Mbit/s are available addressing general purpose 2.4 GHz ISM applications.

The low-power single-chip design enables designers to implement new generation of battery driven systems, save board space and to bring down the overall system Bill of Material (BoM). System development is supported by Atmel's free software stacks, libraries and hardware evaluation and development kits. Learn more about the ATmega128RFA1 evaluation kit

Supported by the QTouch® Library, ATmega128RFA1 makes it easy to combine capacitive touch functionality with RF in a single chip.
