1 Introduction
Thank you for purchasing the CC1110 Mini Development Kit 868-915 MHz or the CC2510
Mini Development Kit.
The CC1110 and CC2510 are System-on-Chip (SoC) devices from Texas Instruments
designed for low power wireless applications. CC1110 operates in the sub-1 GHz unlicensed
ISM bands while the CC2510 operates in the 2.4 GHz unlicensed ISM bands. The CC1110
and CC2510 combine the excellent performance of the state-of-the-art CC1101 and CC2500
RF transceivers respectively with an industry-standard enhanced 8051 MCU, up to 32 kB of
in-system programmable flash memory and up to 4 kB of RAM, and many other powerful
features.
The CC1110 and CC2510 are highly suited for systems where very low power consumption is
required. This is ensured by several advanced low-power operating modes. The small 6x6
mm package further makes it suited for applications with size limitations.
The CC1110 and CC2510 mini development kits include all the necessary hardware in order
to evaluate, demonstrate, prototype and develop software targeting proprietary applications
requiring a sub-1 GHz or 2.4 GHz radio.

5 Getting Started
5.1 Setup
The SmartRF CC1110/CC2510 target board is a complete standalone RF reference platform
with user interfaces and connections needed for development with the CC1110/CC2510.
It can be used both standalone (powered from batteries) or together with the CC Debugger
(for testing and debugging purposes) as shown in Figure 5-1 and Figure 5-2 respectively.
Figure 5-1 – SmartRF CC2510 target board standalone
Figure 5-2 – SmartRF CC2510 target board connected to the CC Debugger
The two SmartRF CC1110/CC2510 target boards in the mini development kit are identical
and come pre-programmed with a link test application. When running the out of the box link
test, the boards can be used standalone. The boards can then be powered from either the 2 x
1.5V AAA batteries that are included in this kit or an external regulated power source (not
included in this kit). The power source can be selected with the jumper on the power selection
connector P1 on the boards. Read more about this in section 6.1.
When not using the out of the box link test (i.e. the preprogrammed application) e.g. for RF
evaluation or software development, the SmartRF CC1110/CC2510 target board can be
connected to the CC Debugger. The SmartRF CC1110/CC2510 target board includes
interfaces for programming and debugging the CC1110/CC2510 via the small connector
marked “Debug”.
The boards further provide access to all the I/O signals from the CC1110/CC2510, two LEDs
and two push buttons.

swru236a
9/26
After assembling the hardware, there are several options for working with the CC1110 and
CC2510 devices:
•Run the link test application that is preprogrammed on the CC1110’s/CC2510’s. The
CC1110 Mini Development Kit 868-915 MHz Quick Start Guide [1] or the CC2510
Mini Development Kit Quick Start Guide [2] included in the kits describes the
necessary steps to run this application.
•Evaluate and explore the RF capabilities of the CC1110/CC2510 using SmartRF
Studio [7]. Chapter 7 provides the details how to do so.
•Develop your own software for the CC1110/CC2510. Install IAR Embedded
Workbench for 8051 [10] and set up your first software project. Section 9.1 explains
how.
•Develop your own hardware with the CC1110/CC2510. See section 6.7.

Figure 6-1 – The SmartRF CC1110/CC2510 target board architecture
6.1 Power Sources
There are several solutions for applying power to the SmartRF CC1110/CC2510 target
boards; batteries, external power or power from the CC Debugger. The desired power source
is selected with a jumper on the power selection connector P1.
Figure 6-2 – The power selection connector on the SmartRF CC1110 and the SmartRF
CC2510 target boards
All power sources are disconnected when no jumper short either pin 1-2 or 3-4 on the power
selection connector. The SmartRF CC1110/CC2510 target boards are reset by disconnecting
the power selection jumper, pressing either of the buttons and then reconnecting the power
selection jumper. The button must be pushed to ensure that the large capacitor on the power
line gets completely discharged; otherwise this could take minutes depending on the current
drawn by the board.
6.1.1 Battery Power
The SmartRF CC1110/CC2510 target boards include two battery solutions. They have battery
holders for both two AAA batteries; normal 1.5 V AAA can be used, and for a 3 V 2032 coin
cell battery on the reverse side of the PCB. The power selection jumper shall short circuit pin

swru236a
11/26
1 and 2 of the power selection connector P1 when using battery power. The jumper can
optionally be replaced with an Ampere meter for current measurements
Note that only one of the battery sources (AAA or coin cell) should be present in the battery
holders at the same time to avoid damaging the batteries.
The pre-programmed link test is optimized for making a robust link and is thus not power
optimized; see more in the CC1110 & CC2510 Mini DK Software Example User’s Guide [3].
For this reason, due to limitations of coin cell batteries, it is not recommended to run the
preprogrammed link test SW on a coin cell battery.
6.1.2 External Power Supply
The SmartRF CC1110/CC2510 target board can optionally be powered from the CC
Debugger or an external power supply. To power the board from the CC Debugger, the CC
Debugger must be connected to the DEBUG connector on the SmartRF CC1110/CC2520
target board, and the jumper must be placed between pin 3 and 4 on the power selection
connector P1. The board will be powered with 3.3 V when powered from the CC Debugger.
To power the board using an external power source, a voltage in the range from 2.0 V to 3.6
V must be applied to pin 3 on the power selection connector P1 or to pin 9 on the DEBUG
connector. Ground from the power supply must be connected to any of the GND pads on the
board. The jumper must be placed between pin 3 and 4 on the power selection connector P1.
The jumper can optionally be replaced with an Ampere meter for current measurements.
Make sure to only have one power source connected at the same time. Note that the voltage
from the external power supply must never exceed the maximum ratings for the CC1110/
CC2510 (-0.3 V to 3.9 V) to avoid damaging the chip.
6.2 Buttons
There are two buttons, MASTER (S1) and SLAVE (S2), on the SmartRF CC1110/ CC2510
target boards. The two buttons are connected to the SoC at pin P1.2 and P1.3 respectively.
Both the buttons are connected to I/O ports without any filtering. On the SmartRF CC1110
target boards, the signals from P1.2 and P1.3 are also available through the test points TP3
and TP6.
6.3 LEDs
There are 2 LEDs on the target boards, D1 (red) and D2 (green). The two LEDs are controlled
from the SoC through pin P1.1 and P1.0 respectively as these have LED driving capabilities.
On the SmartRF CC1110 target boards, these signals are also available through the test
points TP4 and TP5.
6.4 DEBUG Connector (DEBUG)
The SmartRF CC1110/CC2510 target boards contain a debug interface for easy
programming and debugging of the modules. The debug interface connector (DEBUG) pin-
out is shown in Table 1. Note that this connector also provides an SPI or UART interface to
the CC1110/CC2510 (connected to USART0, alternative 1, on the chip) in addition to the
DEBUG interface.
The DEBUG connector includes two VDD connections, one on pin 2 and one on pin 9. The
functions for these connections are different. Pin 2 VDD supplies voltage from the target
board to the signal level converter on the CC Debugger, making it possible to operate at
separate voltages internally on the Debugger and on the SmartRF CC1110/CC2510 target
board. This pin must always be connected when using the CC Debugger. Pin 9 VDD supplies
VDD (3.3 V) from the CC Debugger or from an external power supply.

out. The I/O signals are available through separate test points to provide easy access for
debugging or for connection to external devices.

6.6 Antenna Options
The SmartRF CC1110 and the SmartRF CC2510 target boards both contain PCB antennas
for transmitting/ receiving the RF signals.
Figure 6-3 – The antennas on the SmartRF CC1110 and SmartRF CC2510 target boards
The PCB antenna can optionally be disconnected by turning the R1 resistor on SmartRF
CC1110 target board or the R2 resistor on the SmartRF CC2510 target board 90 degrees
from the PCB antenna position to a test point. By turning the R1/R2 resistor to the test point

swru236a
13/26
position, debugging of the RF signal can be performed or other antenna solutions can be
tested. This is explained in more details in section 7.1.
The antenna on the SmartRF CC1110 target board is highly directive, see more in DN024
[19]. For optimal range when using these boards, it is crucial to place the boards so that the
arrow in the silk print next to the antenna points upwards towards the sky or roof as seen in
Figure 6-4 below.
Figure 6-4 – Correct placement of the SmartRF CC1110 target boards for optimal PCB
antenna performance
Note that the PCB antenna lengths on the SmartRF CC1110 and SmartRF CC2510 target
boards are tuned for optimal performance with two AAA batteries present in the battery
holder. The SmartRF CC1110 target board is tuned for optimal performance in the 868 MHz
band while the SmartRF CC2510 target board is tuned for optimal performance in the 2.4
GHz band. The optimal antenna length for 915 MHz operation (still with the two AAA batteries
in the battery holder) is shown in the silk print on the SmartRF CC1110 target boards.
Removing the two AAA batteries from the battery holder on the board, encapsulating the
board etc. detunes the PCB antenna and thus alters the antenna performance. The detuning
can be compensated for by changing the length of the antenna or adding tuning components
just before the antenna. This is explained in more details in DN024 [19] for the SmartRF
CC1110 target board and AN043 [20] for the SmartRF CC2510 target board.
6.7 Hardware Development
When designing new hardware using the CC1110/CC2510, it is recommended to use either
the CC1110EM/CC2510EM or the SmartRF CC1110/CC2510 target boards as reference
designs. The full CC1110EM/CC2510EM or the SmartRF CC1110/CC2510 target board
reference design files can be downloaded from the CC1110/CC2510 product folder on the
web ([14]/[15]) or the CC1110/CC2510 Mini Development Kit website ([4]/[5]).

swru236a

7 Using SmartRF Studio with SmartRF CC1110/CC2510 Target Boards
RF testing on the mini development kit is best performed by using the PC tool SmartRF
Studio [7]. SmartRF Studio can be downloaded from www.ti.com/smartrfstudio. Follow the
instructions given in the SmartRF Studio User’s Guide [11] to install this tool. The installation
also installs the necessary drivers for the CC Debugger.
To use SmartRF Studio, the SmartRF CC1110/CC2510 target board must be connected to
the CC Debugger as shown in Figure 7-1. Decide which power source to use with the jumper
on P1 (see section 6.1). Connect the CC Debugger to the PC via USB.
Figure 7-1 – SmartRF CC2510 target board connected to CC Debugger
After starting SmartRF Studio and plugging the CC Debugger to the PC via USB, the window
shown in Figure 7-2 or Figure 7-3 will appear depending on which board you have. Make sure
you select the tab called SmartRF®05DK in the top part of the window. The connected
SmartRF CC1110 or SmartRF CC2510 target board will be listed as “CC1110 – new device”
or “CC2510 – new device” respectively. Double click on the new device item, and the window
shown in Figure 7-4 and Figure 7-5 will appear. This is the main control panel for the CC1110/
CC2510. In this window, settings can be changed, tests performed and registers adjusted.
It is highly recommended to use SmartRF Studio actively when finding the optimal RF and
register settings. The following paragraphs will describe how to use SmartRF Studio for
testing TX and RX performance and how to use the tool to send and receive packets.

7.1 Testing TX Parameters
To investigate the TX performance of the CC1110 and CC2510 mini development kits with
the SmartRF Studio, the RF measurement equipment may be connected to the target board
in three different ways:
•Connect an appropriate antenna to a spectrum analyzer and make sure that R1 on
the SmartRF CC1110 target board or R2 on the SmartRF CC2510 target board is
mounted in the PCB antenna direction. Use the “Simple TX” test mode in SmartRF
Studio and set the desired parameters.
•Solder a semi rigid cable to test point T2 on the SmartRF CC1110 target board or T3
on the SmartRF CC2510 target board and turn the R1/R2 resistor from the PCB
antenna position to the test point position, see more in section 6.6. Connect a 50
Ohm coaxial cable from the spectrum analyzer to the semi rigid cable and use the
“Simple TX” test mode in SmartRF Studio to set the desired parameters. This is
illustrated in Figure 7-6.
•Turn the R1/R2 resistor (SmartRF CC1110/ SmartRF CC2510 target board
respectively) from the PCB antenna position to the test point position and connect the
test point to the desired antenna. Connect an appropriate antenna to the spectrum
analyzer. Use the “Simple TX” test mode in SmartRF Studio and set the desired
parameters.
Figure 7-6 - Output power measurement
When testing RF performance, make sure that the spectrum analyzer is calibrated. If
possible, check it against a calibrated instrument such as an RF signal generator. Un-
calibrated spectrum analyzers can display errors of several dBs. Also be aware of the
Resolution Band Width (RBW) setting on the spectrum analyzer. By using good-quality RF
cabling, the loss in the cabling should be negligible. When antennas are used in the
measurements, the “Max Hold” option on the spectrum analyzer should be used.
7.2 Testing RX Parameters
For information regarding sensitivity measurement, refer to DN002 [17]. For conducted
measurements, the kit should be set up with a semi rigid cable as explained in section 7.1. By
adding a jammer (a third node that generates either noise on the same channel or a strong
signal on an adjacent channel), it is also possible to evaluate co-channel rejection and
selectivity/blocking performance.
7.3 Link and Range testing
To test the link quality and range using the CC1110/CC250 mini development kit, you have
several options. You can run “Packet TX” and “Packet RX” tests from SmartRF Studio or you
can use the SmartRF CC1110/CC2510 target boards stand-alone using the preprogrammed
link test.

swru236a
18/26
When using the “Packet TX” and “Packet RX” tests from SmartRF Studio, the two target
boards must be connected to the PC through separate CC Debuggers. Note that the kit only
includes one CC Debugger. To test the link, follow the procedure given below.
•Double click on both of the devices in the device list in SmartRF Studio (Figure 7-2 or
Figure 7-3), opening two windows, and giving control of the two radios at the same
time.
•Select one device to be the transmitter, by selecting the “Packet TX” tab shown in the
lower middle of Figure 7-4 and Figure 7-5.
•On the other device (the receiver), select the “Packet RX” tab.
•Set up basic test parameters and press the “Start packet RX” button.
•Now you can start transmission by pressing the “Start packet TX” button for the
transmitter.
•The status window, in the lower right corner of the device control panel, will show the
number of packets sent on the transmitter side and the number of received on the
receiver side.
To perform practical range testing with the preprogrammed link test application on the
SmartRF CC1110/CC2510 target boards, follow the directions given in the CC1110 Mini
Development Kit 868-915 MHz Quick Start Guide [1] or the CC2510 Mini Development Kit
Quick Start Guide [2]. Note that several parameters like the antenna, register settings and the
environment will affect the range. For more information regarding range testing, please refer
to DN018 [18] and section 6.6.

8 Using SmartRF Packet Sniffer with SmartRF CC1110/CC2510 Target
Boards
You can use the SmartRF CC1110/CC2510 target boards to capture radio packets with the
SmartRF Packet Sniffer [8].
When the board is connected to the CC Debugger, as depicted in Figure 5-2, you can start
the Packet Sniffer.
Figure 8-1 - Start up window of the SmartRF Packet Sniffer
Select and appropriate software protocol (Generic or SimpliciTI) and click the Start button.
Figure 8-2 - Packet Sniffer Setup Panel
In the setup panel of the sniffer, you will see the CC Debugger connected to, in this case, the
CC1110 on the SmartRF CC1110 target board. Also note the “Sniffer communication
interface” radio button in the lower right corner of the window. Please make sure USART0 is
selected.

swru236a
20/26
Figure 8-3 - Packet Sniffer Radio Settings
Before starting, it is necessary to select the radio settings to use for correct packet capturing.
These are the RF register settings which will be written to the CC1110 before it starts to
receive packets. The register settings can be exported from SmartRF Studio in a format that
the SmartRF Packet Sniffer is capable of understanding. Use the “Code export” option in
SmartRF Studio and select the “Packet Sniffer Template”. Save the exported settings in a file
(with extension .prs) and the Sniffer will now be able to open this file and use these settings.
Figure 8-4 - Exporting register settings from SmartRF Studio to the Packet Sniffer
You can now start to capture packets by pressing the “Play” button in the sniffer. Please refer
to the SmartRF Packet Sniffer User Manual [13] for further details.
