RFM219SW
only main features are introduced. Remember that there are two methods to load all these parameters into the device:
Off-line Configuration
Use the RFPDK to directly burn (program) them into the embedded EEPROM of the device. The configuration retains until the
next programming. This is called the off-line configuration.
On-line Configuration
Use the RFPDK to export a HEX file of these parameters, load the content of the HEX file into the external MCU program then
writes the content into the Configuration Bank of the User Registers (See Chapter 5.11) at the beginning of the applications. The
configuration retains until the power down of the device. This is called the on-line configuration.
Either of these method works. To save the external MCU’s effort, method 1 can be used. To save the EEPROM programming
step in the manufacturing stage, method 2 can be used. The table below shows all the configurable parameters.

Descriptions
The receive radio frequency, the range is from 300 to 960
MHz, with resolution of 0.01 MHz.
The demodulation type, the options are: OOK or (G)FSK
demodulation.
The receiver symbol rate, the range is from 0.1 to 40 ksps
for OOK and from 0.1 to 100.0 ksps for (G)FSK, with
resolution of 0.1 ksps.
The threshold of the squelch circuit to suppress the noise,
the range is from 0 to 255.
The sum of the crystal frequency tolerance of the Tx and
the Rx, the range is from 0 to ±300 ppm. And the
calculated BW is configured and displayed.
Time for the device to wait for the crystal to get settled
after power up. The options are: 78, 155, 310, 620, 1240
or 2480 us.
This determines that the chip works in Active mode by
using off-line configuration or works in Passive mode by
using on-line configuration.

The sleep time has the range from 3 to 134,152,192 ms.
It is only available when Active mode is selected or Sleep
Timer is on in Passive mode.
This turns on/off the receive timer.
The receive time has the range from 0.04 to 2,683,043.00
ms. It is only available when Active mode is selected or
Rx Timer is on in Passive mode.
The extended receive time has the range from 0.04 to
2,683,043.00 ms. It is only available when Wake-On
Radio is turned on and the Rx Timer is turned on.
Turn on/off the Rx early exit function, the options are: on
or off.
