Circuit Interface
Note:
1. The module power supply voltage range is DC 1.8~3.6V, above DC 3.6V, the module will damage. It is recommended work at DC 3.3 V.
2. The module interface use half circle pad to soldering on the system PCB board, the GND must soldering to the system digital GND reliably.
3. The antenna must the get to the module’s ANT pin as close as possible.
4. The MCU which don’t have integrated SPI interface can also control the module, use the normal I/O port to work like SPI timing to read and write. The SPI data rate is below 10MHz.
5. The interface can connect directly to the MCU which use 3.3V power supply, there is no need serial resistor. If the I/O is open-drain, the pull-up resistor will be added. When connect to the MCU which use 5V power supply, the MCU’s I/O output current beyond 10 mA, a 2~5k ohm resistor will be series to divide the voltage, or it will damage the module.
6. The module’s pin GDO0 is a general digital I/O port, it can be programmable to produce trigger signal or clock output.
7. The PA control voltage have an effect on the communicate distance and power consumption. In transmit mode, set TE=0 and RE=1; in receive or sleep mode, set TE=1 and RE=0.
8. In the multiple channel application, the channel spacing is recommended to set as 1MHz, or there will be a same frequency interference.
Operation States
CC2500’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. CC2500’s radio control state diagram is shown as below, for detail information in the CC2500 datasheet.
Data Transmission
The CC2500 contains a 64 byte transmit/receive FIFOs, 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, CC2500 supports fixed packet length protocols, variable packet length protocols and infinite packet length. Details refer to the CC2500 datasheet.
Configuration Registers
The configuration of CC2500 can be done with software SmartRF Studio7. Complete descriptions of the registers are given in the CC2500 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 CC2500-datasheet. 3.There is a carrier frequency interference, change the channel. 4.The antenna unmatched to the module RF interface, change another matched antenna. |
