AT86RF211SAHW 技术参数

General Overview

General Overview of

Functioning

The AT86RF211 is a microcontroller RF peripheral: all the user has to do is to write/read

registers to setup the chip (i.e. frequency selection) or have information about parame-

ters such as RSSI level, Vbattery, PLL lock state. All these operations are carried out via

a three-wire serial interface.

Normal Mode

The chip is set-up by the microcontroller: frequency and mode (Rx or Tx). Then it acts

like a "pipe": any data entering DATAMSG is immediately radiated (Tx) or any wanted

signal collected by the aerial is demodulated, transferred to the microcontroller by the

same pin DATAMSG (Rx) as reshaped bits. No data is stored or processed into the

chip. See Figure 1.

Note:

In Rx mode, a clock recovery DATACLK is available on the digital interface to provide the

microcontroller with a synchronization signal.

Wake-up Mode

The chip is set up in a special Rx mode called sleep mode. The chip wakes up periodi-

cally thanks to its internal timer (stand alone procedure, the microcontroller is in power-

down mode), waiting for an expected message previously defined. If no correct

sequence is received, the periodic scan continues.

If a correct message is detected, its data field is stored into the AT86RF211 (up to 32

bits) and an interrupt is generated on the WAKEUP pin.

See Figure 2 and Figure 3.
