Table 15: Bill Of Materials for the application circuit
In the CC2500EM reference design LQG-15
series inductors from Murata have been used.
Measurements have been performed with
multi-layer inductors from other manufacturers
(e.g. Würth) and the measurement results
were the same as when using the Murata part.
8 Configuration Overview
CC2500 can be configured to achieve optimum
performance for many different applications.
Configuration is done using the SPI interface.
The following key parameters can be
programmed:
• Power-down / power up mode
• Crystal oscillator power-up / power-down
• Receive / transmit mode
• RF channel selection
• Data rate
• Modulation format
• RX channel filter bandwidth
• RF output power
• Data buffering with separate 64-byte
receive and transmit FIFOs
• Packet radio hardware support
• Forward Error Correction with interleaving
• Data Whitening
• Wake-On-Radio (WOR)
Details of each configuration register can be
found in Section 31, starting on page 49.
Figure 4 shows a simplified state diagram that
explains the main CC2500 states, together with
typical usage and current consumption. For
detailed information on controlling the CC2500
state machine, and a complete state diagram,
see Section 19, starting on page 34.
