The CC2550 is a low cost true single chip 2.4 GHz transmitter designed for very low power wireless applications. The circuit is intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency band at 2400-2483.5 MHz. The RF transmitter is integrated with a highly configurable baseband modulator which has a configurable data rate up to 500 kbps. Performance can be increased by enabling a Forward Error Correction option, which is integrated in the modulator. 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. CC2550 is part of Chipcon’s 4th generation technology platform based on 0.18 µm CMOS technology. This data sheet contains preliminary data, and supplementary data will be published at a later date. Chipcon reserves the right to make changes at any time without notice in order to improve design and supply the best possible product. The product is not fully qualified at this point.
The CC2550 is a true single‑chip 2.4 GHz transmitter intended for ISM/SRD band systems (2400‑2483.5 MHz). It integrates a configurable baseband modulator, SPI‑controlled registers, and a 64‑byte TX FIFO, allowing use with a microcontroller and minimal external components.
Key features include programmable output power (‑30 dBm to +1 dBm), selectable modulation formats (OOK, FSK, GFSK, MSK), optional forward error correction, and built‑in analog temperature sensing. The device is supplied in a 4 × 4 mm QLP 16‑pin package and operates from 0.3 V to 3.6 V supply voltage.
