1 / 59 page  CC2550 SWRS039B Page 1 of 58 CC2550 Low-Cost Low-Power 2.4 GHz RF Transmitter 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 appli- cations. The circuit is intended for the 2400- 2483.5 MHz ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) freq- uency 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 micro- controller 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 multi- channel systems due to a fast settling frequency synthesizer with 90 us settling time • Integrated analog temperature sensor 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 on- chip frequency synthesizer, no external filters needed • Green package: RoHS compliant and no antimony or bromine • Small size (QLP 4x4 mm package, 16 pins) • Suited for systems compliant with EN 300 328 and EN 300 440 class 2 (Europe), FCC CFR47 Part 15 (US), and ARIB STD- T66 (Japan) • Support for asynchronous and synchronous serial transmit mode for backwards compatibility with existing radio communication protocols |
