CC2550RSTR

The Texas Instruments CC2550RSTR is a single-chip, low-cost RF transmitter designed for low-power wireless applications operating in the 2.4 GHz ISM band. It supports modulation schemes including OOK, 2-FSK, GFSK, and MSK, making it suitable for frequency hopping and multichannel systems due to its fast settling frequency synthesizer.

Key electrical specifications include a programmable output power up to +1 dBm and a programmable data rate from 1.2 to 500 kBaud. The device operates within a frequency range of 2400 - 2483.5 MHz and requires an operating voltage between 1.8V and 3.6V, drawing 21.3mA of current. It features low-power modes with a sleep current of 200 nA and a fast startup time of 240 µs from sleep to TX mode.

This transmitter is housed in a compact 16-VQFN (4x4 mm) package and is designed for surface mounting. It requires few external components, featuring an on-chip frequency synthesizer that eliminates the need for external filters. The CC2550RSTR is suited for systems compliant with various international standards including FCC CFR47 Part 15 in the US and EN 300 328 in Europe.

Applications for the CC2550RSTR include 2400-2483.5 MHz ISM/SRD band systems, consumer electronics, wireless game controllers, and wireless audio.
