Si4010 EZRADIO REMOTE CONTROL DEMO 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 boad 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.
Kit Part Number
EZR-LEDK1W-434
EZR-LEDK1W-868
EZR-LEDK1W-917
Center Frequency
433.92 MHz
Deviation
59 kHz
868.30 MHz
119 kHz
120 kHz
917.00 MHz
The modulation is FSK.
4. Transmitter Side Program
The Si4010 in the key fob 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:
Number of Bytes
Field Name
Preamble
Sync
Description
0xaa

Chip ID
Unique, factory-burned chip ID
Lower 5 bits are the button information
Rolling counter for PER measurement
Generator X16+X15+X2+1, start value 0xFFFF

Status

Packet count
CRC-16
2
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. Receive Side Program
The 8051F930 MCU on the RFStick transmitter board is factory-programmed with the stx_demo 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
stx_demo software project can be found in the example programs package of the Si4355. It is available at the web
page http://www.silabs.com/products/wireless/EZRadio/Pages/Si4355.aspx on the Tools tab.
The receiver prgoram 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.
