Single-Chip Low Cost Low Power RF-Transmitter (Rev. B)
Texas Instruments
Description
The CC2550 is a low-cost 2.4 GHz transmitter designed for very low-power wireless applications. The circuit is intended for the 2400-2483.5 MHz ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency band. The RF transmitter is integrated with a highly configurable baseband modulator. The modulator supports various modulation formats and has a configurable data rate up to 500 kBaud. 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 passive components.
