1. Overview
Thank you for your interest in Silicon Laboratories EZRadio® Si4356 Standalone Receiver Development Kit (P/N
4356-LEDK1W-XXX). The kit contains everything you need to familiarize yourself with and evaluate the EZRadio®
Si4356 standalone direct mode receiver. The kit has two versions: one for the 434 MHz band and one for the 868
MHz band. The key features of the development kit are as follows:
1. Transmitter node is a preprogrammed demo keyfob with Si4010 Transmitter SOC.
2. Receiver node is a switch configurable Si4356 demo board.
3. The receiver demo board has four LEDs to display information and four push-buttons to receive user
commands.
4. The Silabs website provides all the documentation and files needed to develop a user application.
5. The kit supports the use of the Silicon Laboratories Integrated Development Environment (IDE) for
software debugging and the use of the Keil & SDCC C compiler, assembler, and linker tool chain.
The demo boards come with a direct mode reception demo application. The demo implements deglitching,
retiming, and decoding of the received data stream.

Set the S6 power switch to “Adapter” position.
Connect the RFStick to the Toolstick Base Adapter via the PCB edge connector.
Connect the Base Adapter to a USB port of a PC directly or using the USB extender cable.
If necessary wait for Windows to install the debug interface driver.
RFSticks can be shipped without preloaded software, or the software on the board can be out of date. So
upon first use, it is advised to upgrade the firmware in the MCU of the RFStick. The complete Si4356
Development Kit RX side code project can be downloaded from
http://www.silabs.com/Support%20Documents/Software/4356_rfstick_dir_SW.zip.
6. Start the Silabs IDE and close any open project.
7. Before connecting to the target device, several connection options may need to be set. Open the
Connections Options window by selecting Options
Connection Options...in the IDE menu. First select the
Rev. 1.2

Si4356- DK
USB Debug Adapter in the “Serial Adapter” section. Next, the C2 Debug Interface must be selected. Once
all the selections are made, click the OK button to close the window.
8. Click the Connect button in the toolbar or select Debug
Connect from the menu to connect to the device.
9. Download the project to the target by clicking the Download Code button in the toolbar and browsing to the
4356-rfstick-dir.hex file of the out folder of the Si4356 Development Kit RX side code project.
10. Click the Disconnect button in the toolbar to start the operation of the downloaded example code.
To operate the RFStick without USB connection, insert two AAA batteries in the battery holder on the bottom side
of the board and set the power switch to “Battery” position.
4. Operating the Direct Mode Reception Demo
The Si4010 keyfob transmitter and the Si4356 RFStick receiver are the transmitter and receiver nodes used in the
direct mode reception demo. After setting up the nodes according to the previous chapter, the Si4356 has to be
configured for the RF parameters of the demo, using the SEL0 – SEL3 slide switches and the SW1-1 to SW1-4 DIP
switches on the RFStick. SEL0 and SEL1 set the center frequency according to Table 2. The part number of the
board contains information on the frequency band (434 or 868) that the matching circuit of the board was designed
for. Using the board in a different band results in significantly reduced sensitivity.

The buttons on the keyfob have been programmed to transmit various packet formats. Details on the RF settings
and packet formats associated with each button are provided in Section 5. The Si4356 RFStick will only respond to
keyfob button transmissions that it has been configured to receive. The slide and DIP switches on the Si4356
RFStick are used to configure the Si4356 IC. Table 3 and Table 4 highlight the required configurations for each
keyfob button. Note that the keyfob button names have been defined according to their position when the keyfob
LED is oriented on top.

After turning on the demo the first time, it needs to be paired with a keyfob. LED1, LED2, LED3, and LED4 will
begin blinking after the device has been initialized, showing that it is waiting for association. The Si4356 RFStick
will associate with the keyfob that sends the first valid packet. If a proper packet is received, the receiver node
stores the unique ID of the keyfob into its MCU’s RAM memory and will stop flashing the four LEDs (indicating a
successful association) and will enter receive mode. In receive mode, LED1 will be continuously on. The Si4356
will accept packets from the associated keyfob and flash the LEDs listed in the "Valid Packet RX" column of Table 3
and Table 4 when receiving a valid packet. Pressing the PB1 button will clear the associated keyfob and cause the
Si4356 RFStick to wait for a new association.
5. Transmitter Node
Figure 3. Demo Keyfob
The Si4010 transmitter SOC in the keyfob of the kit is factory programmed with the 4010-kfob-dir program. Since
the program is burned in the NVM (OTP) memory of the Si4010, it cannot be changed.
For keyfob development with the Si4010 transmitter SOC, it is recommended to use the
Si4010/Si4355
Development Kit (P/N 4010-KFOBDEV-xxx),
available from Silabs. The complete 4010-kfob-dir software project
is available in the example programs package of the
Si4010 product webpage.
The schematic of the keyfob can be found at the end of the document.
The keyfob transmits an RF packet four times each time a button is pressed, and it also blinks the LED on the
keyfob. The transmitted packet is different for each button, according to Table 5. Note that the keyfob button
names have been defined according to their position when the keyfob LED is on top.
