EMO KIT USER’S GUIDE

1. Purpose

Thank you for your interest in Silicon Laboratories’ EZRadio Remote Control Demo Kit. The Silicon Laboratories

EZRadio Remote Control Demo Kit (P/N EZR-LEDK1W-XXX) contains everything you need to familiarize yourself

with and evaluate the Si4010 RF SoC transmitter and the Si4355 receiver. The kit has three versions: one for the

434 MHz band, one for the 868 MHz band, and one for the 915 MHz band. The key features of the demo kit are as

follows:

The key fob demo board has five push buttons and one LED output.

The receiver demo board has four LEDs to display received key fob commands.

The provided software pack contains all the documentation and files needed to develop a user application.

The kit supports the use of the Silicon Laboratories Integrated Development Environment (IDE) for

software debugging and the use of the Keil C compiler, assembler, and linker toolchain.

Contains demo applications using API functions and the key fob demo application.

2. Operating the Demo

The Si4010 key fob transmitter and the Si4355 RFStick receiver are the transmitter and receiver devices used in

the one way link demo. This transmitter/receiver pair can be used to evaluate the capabilities of the Si4010

transmitter and the Si4355 receiver.

The first step is to insert the CR2032 battery in the battery holder on the 4010-KFOB-XXX demo board and then

place the board into the plastic key fob case. Next, insert the two AAA batteries in the battery holder on the 4355-

LED-XXX receiver board and turn it on by setting the S6 switch to the “Battery” position. LED4 will light

continuously indicating that power is on and the SRX firmware is running.

When a button is pressed on the key fob, LEDs flash on the receiver board according to which button was pressed.

In the next table, buttons are named according to their position when the key fob is held with its LED facing

forward.

3. RF Parameters

The demo kit uses the following RF parameters according to the kit’s frequency band.

The modulation is FSK.

4. Transmitter Side Program

The Si4010 in the key fob is factory programmed with the rke_demo_2 program. Since the program is burned in

the NVM (OTP) memory of the Si4010, it cannot be changed. The whole rke_demo_2 software project can be

found in the example programs package of the Si4010. It is available at the web page

http://www.silabs.com/products/wireless/EZRadio/Pages/Si4010.aspx on the Tools tab.

The key fob transmits an RF packet three times each time a button is pressed, and it also blinks the LED on the key

fob. The packet structure is as follows:

Symbol rate is 9.6 kBd.

Each packet contains 18 additional bytes that are not received by the receiver of this demo. These additional bytes

are AES-encrypted and are used by the AES demo kit. See details in the user’s guide of the AES demo kit (P/N

4010-AESK1W-434).

In the key fob program the frequency and deviation is pin-selected by the PCB layout. This operating frequency is

indicated on a label on the back of the key fob PCB.

The 316.667 MHz key fob is available in the 4010-AESK1W-315 demo kit or separately from Silicon Labs.

The key fob’s default modulation is FSK but if the middle button is pressed and held during battery insertion, the

modulation will be OOK until the next powerdown (battery removal).

5. Receiver Side Program

The 8051F930 MCU on the RFStick receiver board is factory-programmed with the Si4355 Remote Control Demo

Receiver program. Since the program is programmed in flash memory, it can be overwritten using a Silicon Labs

Toolstick Base Adapter that is part of the Si4010 development kit or can be ordered separately as well (P/N

Toolstick_BA). The complete demo software project can be found on the Tools tab of the following web page:

http://www.silabs.com/products/wireless/EZRadio/Pages/Si4355.aspx. The file name is Si4355_RCdemo_SW.zip.

The receiver program configures and controls the Si4355 receiver chip via the SPI bus. The Si4355 receives the

packets transmitted by the keyfob, checks the preamble, the syn bytes and the CRC. If the packet is OK, the

program flashes the LEDs according to the button information in the status byte of the received packet.

6. Schematics

Schematics of the transmitter and receiver boards of the kit can be seen on the following pages. Complete

manufacturing file pack with CAD/CAM files and BOMs can be found at http://www.silabs.com.
