Applications

• 2400-2483.5 MHz ISM/SRD band systems

• Consumer electronics

• Wireless game controllers

• Wireless audio

• RF enabled remote controls

Product 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.

Key Features

RF Performance

• Programmable output power up to +1 dBm

• Programmable data rate from 1.2 to 500

kBaud

• Frequency range: 2400 – 2483.5 MHz

Analog Features

• OOK, 2-FSK, GFSK, and MSK supported

• Suitable for frequency hopping and multichannel

systems due to a fast settling

frequency synthesizer with 90 us settling

time

Digital Features

• Flexible support for packet oriented

systems: On-chip support for sync word

insertion, flexible packet length, and

automatic CRC handling

• Efficient SPI interface: All registers can be

programmed with one “burst” transfer

• Optional automatic whitening of data

Low-Power Features

• 200 nA SLEEP mode current consumption

• Fast startup time: 240 us from SLEEP to

TX mode (measured on EM design [3])

• 64-byte TX data FIFO (enables burst

mode data transmission)

General

• Few external components: Complete onchip

frequency synthesizer, no external

filters needed

• Green package: RoHS compliant and no

antimony or bromine

• Small size (QLP 4x4 mm package, 16

pins)

328 and EN 300 440 class 2 (Europe),

FCC CFR47 Part 15 (US), and ARIB STDT66

(Japan)

• Support for asynchronous and

synchronous serial transmit mode for

backwards compatibility with existing radio

communication protocols
