CC2550

Single Chip Low Cost Low Power RF-Transmitter

Applications

• 2400-2483.5MHz ISM/SRD band systems

• Wireless game controllers

• Wireless audio

• Consumer Electronics

Product Description

The

CC2550 is a low cost true single chip

2.4GHz transmitter designed for very low

power wireless applications. The circuit is

intended for the ISM (Industrial, Scientific and

Medical) and SRD (Short Range Device) freq-

uency band at 2400MHz-2483.5MHz.

The RF transmitter is integrated with a highly

configurable baseband modulator which has a

configurable data rate up to 500kbps. The

communication range can be increased by

enabling a Forward Error Correction option,

which is integrated in the modulator.

The

CC2550 provides extensive hardware

support for packet handling, data buffering and

burst transmissions.

The main operating parameters and the 64-

byte transmit FIFO of

CC2550 can be controlled

via an SPI interface. In a typical system, the

CC2550 will be used together with a micro-

controller and a few additional passive

components.

CC2550 is based on Chipcon’s SmartRF®04

technology in 0.18

µm CMOS.
