Note：
1．The module transmission data rate will affect transmission distance and receiving sensitivity, the higher the data
rate , the closer the distance, and the lower the receiving sensitivity.
2．The supply voltage to the module will affect TX power, in the operating supply voltage range, the lower the
voltage, the lower the TX power.
3．The module central frequency will change as the operating temperature change, use it under suggest temperature,
the module can work well.
4．The antenna will strongly affect the communication distance, please select matched antenna and connect it
correctly.
5．The module mount will affect the communication distance.

Special character pin
1. EEPROM control pin(optional)
The module integrated 2~64KB EEPROM, the interface is I2C, and CC1110’s pin P2.1 and P2.2 are used as
EEPROM’s clock(SCL) pin and data(SDA) pin. These two pins are also debug pins, so the EEPROM doesn’t
support IAR.
If you purchase the module integrated EEPROM, we will provide the read/write code.
2. Simulation debugging interface(DEBUG)
CC1110 integrated 8051 microcontroller core support IAR, the debugging interface include clock pin
P2.2(DCLK) and data pin(DDA), you can connect these two pins to the simulator interface on the programming,
detail information refer to CC1110 datasheet.
3. Strong driver pins
CC1110’s port P1.0 and P1.1 can supply 20mA current to drive LED directly, detail information refer to CC1110
datasheet.
4. Status output pin
CC1110’s port P1.5, P1.6 and P1.7 are configurable pins that can output internal status information useful for
control software. More details refer to CC1110 datasheet.

Operation States
CC1110’s operation states contain: Sleep State, Idle State, Active State，Sleep State is the lowest power mode.
After wake up from Sleep State, the module get into Idle State. Except the Sleep State, each state can be switch by
SPI interface, also programmed to auto-switch. CC1110’s radio control state diagram is shown as below, for detail
information in the CC1110 datasheet.

Data Transmission
The CC1110 contains a 64 byte FIFO for data to be transmitted, built-in hardware support for packet oriented
radio protocols, e.g. Preamble bytes, Synchronization Word, Whitening the data, CRC checksum, Interleave and
Forward Error Code, Address checksum. The SPI interface is used for sending commend control and writing to
the TX FIFO.
The format of the data packet can be configured and consists of the following figure：
In addition, CC1110 supports fixed packet length protocols, variable packet length protocols and infinite packet
length. Details refer to the CC1110 datasheet.
Configuration Registers
The configuration of CC1110 can be done with software SmartRF Studio7. Complete descriptions of the registers
are given in the CC1110 datasheet. We can provide evaluation board and demo code to the customer to develop
and evaluate the module’s capability.

Questions and Answers
Description
Reason and Solution
Can’t
communication
1．The power supply connect not well, check the module VCC whether it is out of maximum
rating.
2．The signal line connect not well, check the module SPI interface.
3．The settings of the transmitter module and receiver module are not the same. Check these
modules’ register configuration.
4．Signal block. If the transmitter work with a high TX power, and the receiver was put at a short
distance(<0.5m), maybe there is a signal block to make no communication.
Communication
distance is too
short
1．The application environment is too bad or the antenna is shield. Put the antenna to a better place
outside or higher throw a coaxial line , replace it with a higher gain antenna.
2．The work space contains a same frequency interference source, or a strong magnetic field
interference, power source disturbance. Try to change the carrier frequency or get far away from
the source of the disturbance.
3．The power supply is not strong. Check the voltage and the current whether it is enough.
High data error
1．The power supply ripple is too big, Change the power supply.
2．Check the module register configuration, it is recommended to set as the CC1110-datasheet.
3．There is a carrier frequency interference, change the channel.
4．The antenna unmatched to the module RF interface, change another matched antenna.
