Within the EFP01 family, only EFP0108, EFP0109, EFP0110, EFP0111 can be used as a Boost converter for an application that has source voltage less than the desired load voltage. Out of all available OPNs, there are only two development boards – BRD8100A [EFP0108] and BRD8100B [EFP0111] currently available that can be used to develop such an application.
If the user wants to develop an application for EFP0109 but is interested to test his proof of concept before prototyping, the user can use BRD8100A to approximate EFP0109 along with the hardware and software modifications explained in Case 2 of this KBA.
Case 1 [0.8V < Vin < 1.8V]
For source voltage less than 1.8V, BRD8100A (EFP0108) can be used with the following steps:
Step 1: Power VIO by connecting the USB cable to the reference board.
Step 2: Connect VIN (0.8V to 1.8V) through an external source or connect onboard a low voltage regulator by shorting ST208.
Step 3: Using Simplicity Studio – EFP Configuration Tool, load the desired register settings to the device.
Step 4: Connect load at the VOA terminal.
Case 2 [1.8V < Vin < 3.6V]
For source voltage more than 1.8V, the hardware of BRD8100A (EFP0108) can be modified similar to connections of EFP0109 with the following steps:
Step 4: Connect external Host MCU using P202 and an additional common GND pin. Please note that external Host MCU such as EFM32/EFR32 starter kit will be required to program correct register settings into the EFP0108 after the initial start-up sequence.
Step 5: Create any sample project in Simplicity Studio 5 to utilize the existing I2C firmware, add software component of EFP01 instance to the project. Create a new function for EFP01, create new handle, initialize the EFP and add the following C code to the sample project:
Note that custom applications may have different register settings requirements than what is recommended above. Hence correct register values should be set by referring to the latest revision of the EFP01 datasheet.
The above settings will configure the outputs to the following voltages:
VOA = 3.33V
VOB = 1.17V
VOC = 1.86V
The maximum output voltage obtained at VOB will be limited to 1.2V rather than 3.3V as on EFP0109 due to the physical limitation and presence of EFP0108 on the development board.
Step 6: Power VIO from the external MCU board.
Step 7: Connect VIN (1.8V to 3.6V) through an external source.
Step 8: Load the register settings of EFP0108 using an external MCU.
The purpose of this KBA is to organize all Wireless Hardware related specific/generic technical documents (application notes and KBAs) applicable to EFR32 Series 2 SoCs and Wireless modules in one place. The content is grouped into the following categories to make it easier to find what you are looking for.
This Knowledge Base Article (KBA) aims to organize all Wireless Hardware related technical documents and related individual KBAs for EFR32 Series 1 SoCs and Wireless modules together in one place.
The KBA organizes all technical documents into categories for a better and convenient way to refer to the contents while designing a custom application based on these parts. The categorized RF hardware contents are as follows:-

A STEP [STandard Exchange of Product model data] file is a CAD file format defined by ISO 10303-21 to represent 3D models of components and assemblies. Since STEP files conform to the ISO standard, they are not vendor or software specific and have been adopted by the majority of ECAD and MCAD [Electronic and Mechanical Computer Aided Design] tools and systems.
STEP files are helpful to understand the physical dimensions of a particular product in a 3D domain. STEP files are also helpful to understand the area required by the part on the PCB during component placement in the mechanical assembly.
The following figure shows a sample for the preliminary STEP files for BGM13P22GA (Built-In Antenna) and BGM13P22GE (External Antenna) variants:
If there is any STEP file for a typical wireless module that is not available on the website, then respective Preliminary STEP files can be obtained from Silicon Labs by contacting the Technical Support team.
There are different STEP files for different part variations. For example, the BGM13PGA (built-in antenna) STEP file is different from the BGM13PGE (external antenna) STEP file. The example highlights the difference between a Bluetooth module with a U.FL connector versus a module with a chip antenna. When requesting STEP files, please include the correct part number so that the correct file can be provided. Once received, please refer to your CAD's website or help for instructions on how to import STEP files.
To obtain a STEP file for a standard package such as QFN32, QFN48, etc, please contact our Technical Support team where you will receive a .bxl [Binary eXchange Language] file, which is a proprietary file format for vendor-neutral CAD data created by UltraLibrarian tool available on our website. Once you receive the .bxl file, please follow the instructions on the CAD/CAE webpage to generate appropriate files for your project.
