Configuration Overview

CC2550 can be configured to achieve optimum

performance for many different applications.

Configuration is done using the SPI interface.

The

following

key

parameters

can

programmed:

•

Power-down / power up mode

•

Crystal oscillator power-up / power – down

•

Transmit mode

•

RF channel selection

•

Data rate

•

Modulation format

•

RF output power

•

Data buffering with 64-byte transmit FIFO

•

Packet radio hardware support

•

Forward Error Correction with interleaving

•

Data Whitening

Details of each configuration register can be

found in Section 27, starting on page 34.

Figure 4 shows a simplified state diagram that

explains the main

CC2550 states, together with

typical usage and current consumption. For

detailed information on controlling the

CC2550

state machine, and a complete state diagram,

see Section 16, starting on page 23.
