Synchronous Receive Modes
Wake-up Mode
In addition to the modes described above, the AT86RF211S provides a clock signal that facilitates
recovery of data by any low-cost MCU (no UART controller, for instance).
The data can also be synchronized on this clock signal; the benefits of this are:
Figure 3-3.
The chip is set-up in a special Rx mode called sleep mode. The chip wakes up periodically thanks to its
internal timer (in a stand-alone procedure, the microcontroller is in power-down mode), and waits for an
expected message defined previously. If no correct sequence is received, the periodic scan continues.
If a correct message is detected, its data field is stored into the AT86RF211S (up to 32 bits) and an inter-
rupt is generated on the WAKEUP pin.
Please refer to
• Bit decision is done on-chip
• Jitter is removed
• Processing time constraints on the MCU are eliminated
