Connecting the CC Debugger to a Transceiver

The SPI interface on the CC Debugger can be used to interface many of the CCxxxx transceivers and

control them from SmartRF Studio. The transceivers, transmitters, and receivers currently supported are:

•

CC1100

•

CC1101

•

CC1120

•

CC1121

•

CC1125

•

CC1175

•

CC110L

•

CC113L

•

CC115L

•

CC1200

•

CC1201

•

CC2500

•

CC2520

Note that the CC Debugger operates as the SPI Master. In a multi-master system, it is necessary to make

sure the debugger output signals (DC, DD, CSn, SCLK, MOSI and RESETn) do not interfere with the

other SPI master on the board. The other SPI master would typically be the microcontroller on the board.

Figure 8 through Figure 10 show the interconnection between the debugger and the various supported

transceivers.
