Connecting the CC Debugger to the Device
6.3 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.
