CC1021
8. Configuration Overview
CC1021 can be configured to achieve the
optimum performance for different
applications. Through the programmable
configuration registers the following key
parameters can be programmed:
• Receive / transmit mode
• RF output power
• Frequency synthesizer key parameters:
RF output frequency, FSK frequency
8.1. Configuration Software
Chipcon provides users of CC1021 with a
software program, SmartRF Studio
(Windows interface) that generates all
necessary CC1021 configuration data
based on the user's selections of various
parameters. These hexadecimal numbers
will then be the necessary input to the
microcontroller for the configuration of
separation, crystal oscillator reference
frequency
• Power-down / power-up mode
• Crystal oscillator power-up / power-
down
• Data rate and data format (NRZ,
Manchester coded or UART interface)
• Synthesizer lock indicator mode
• Digital RSSI and carrier sense
• FSK / GFSK / OOK modulation
. CC1021 In addition, the program will
provide the user with the component
values needed for the input/output
matching circuit, the PLL loop filter and the
LC filter.
Figure 5 shows the user interface of the
CC1021 configuration software.

Note: The CC1020/1070DK Development Kit with a fully assembled CC1020EMX Evaluation
Module together with the CC1021 specific software should be used for evaluation of the CC1021
transceiver.
