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) frequency band at 2400MHz-2483.5MHz.

The RF transmitter CC2550 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 microcontroller and a few additional passive components.

CC2550 is based on Chipcon's SmartRF^®04 technology in 0.18m CMOS.
