Low Cost 2.4 GHz Transmitter Designed for Low-Power Wireless Applications in 2.4 GHz ISM Band

 

Not Recommended for New Designs (NRND)

Replaced By CC2500 – The device is an EXACT EQUIVALENT in functionality and parametrics to the compared device. The replacement device is a transceiver where the transmitter has all the same capabilities as the CC2550.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.

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.
