A sub 1 GHz radio frequency (RF) transceiver is now available from Texas Instruments Incorporated (TI). The CC1101 is specifically designed for low-power wireless applications like alarm and security, automatic meter reading, industrial monitoring and control and home and building automation system. The CC1101 includes operating parameters and the 64-byte transmit/receive FIFOs, which can be controlled through an SPI interface. The sub-1GHz RF transceiver can be used with a microcontroller (MCU) like TI TI’s MSP430 ultra-low-power MCUs. The CC1101 offers extensive hardware to support variety of things, which are given below: 1) Package handling 2) Data buffering 3) Burst transmissions 4) Clear channel assessment 5) Link quality indication 6) Wake-on radio The sub-1GHz RF transceiver is designed for the Industrial, Scientific and Medical (ISM) and Short Range Device (SRD) frequency bands at 315, 433, 868 and 915MHz. The device can also work for other frequencies in the 300-348MHz, 387-464MHz and 779-928MHz bands. In addition, the CC1101 has an improved performance and code compatible version of TI’s successful CC1100 sub-1GHz RF transceiver. The CC1101 has improved spurious response, better close-in phase noise, higher input saturation, improved output power ramping and extended frequency bands. The CC110 is available at $1.85 in 1,000-unit quantities.
