CC2550 (NRND)

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.
