immunity, range, etc), and software protocol (single channel, frequency agility, listen before transit, FHSS). The
AT86RF211S is also well adapted to battery-operated systems, as it can be powered with as little as 2.4V. It also offers a
"wake-up" receiver feature to save power by alerting the associated microcontroller only when a valid inquiry is detected.

The AT86RF211S is a microcontroller RF peripheral. The chip’s setup is done by writing
or reading the registers (for example, frequency selection) or by obtaining information
on the parameters such as RSSI level, Vbattery or PLL lock state. These operations are
all carried out via a three-wire serial interface.
The AT86RF211S now replaces the AT86RF211, and offers numerous new features.
The AT86RF211S can operate in two different modes, described in the following table:
The AT86RF211S has a data rate of up to 100 kbps. The modulator and demodulator
have been optimized to increase the speed of the RF links while maintaining a high per-
formance level.
The receiver’s bandwidth has been increased to 250 kHz for very wide band applica-
tions in the US.
It is now possible to run the XTO alone; this is useful for real-time demanding applica-
tions. The sinked current is 150 µA, increasing according to the load capacitance when
the XTO signal is buffered, to be fed to a companion microcontroller (thus saving on the
cost of the crystal for the MCU).
The ADC clock period can now be decreased from 12 to 1.5 µs. Faster channel scan-
ning in multi-channel applications or LBT (Listen Before Transmit) is then possible, as
well as ASK demodulation for low data rates.
It is now easy to use a 20.5 MHz crystal and feed a very fast clock to the companion
MCU, and yet keep the IF1 at 10.7 MHz. Commercially-available filters at this frequency
are inexpensive and multisource.
