The CC2400 is a true single-chip 2.4 GHz RF transceiver designed for low-power and low-voltage wireless applications. The RF transceiver is integrated with a baseband modem supporting data rates up to 1 Mbps. The CC2400 is a low-cost, highly integrated solution enabling robust wireless communication in the 2.4 - 2.4835 GHz unlicensed ISM band. It is intended for systems compliant with world-wide regulations covered by EN 300 440 (Europe), CFR47 Part 15 (US) and ARIB STD-T66 (Japan). Targeting a wide range of applications at 2.4 GHz, the CC2400 supports over-the-air data rates of 10 kbps, 250 kbps and 1 Mbps without requiring any modifications to the hardware. The CC2400 provides extensive hardware support for packet handling, data buffering, burst transmissions, data coding and error detection reducing the workload on the host microcontroller. The main operating parameters of CC2400 can be programmed via an SPI-bus. In a typical system CC2400 will be used together with a microcontroller and a few external, passive components. CC2400 is based on Chipcon’s SmartRF-03 technology in 0.18 µm CMOS.
