5.3 Embedded EEPROM and RFPDK
The RFPDK (RF Products Development Kit) is a very user-friendly software tool delivered for the user configuring the
RFM110W/RFM117W in the most intuitional way. The user only needs to fill in/select the proper value of each parameter and
click the “Burn” button to complete the chip configuration. No register access and control is required in the application program.
See the figure below for the accessing of the EEPROM and Table 11 for the summary of all the configurable parameters of the
RFM110W/RFM117W in the RFPDK.
