RF transceiver delivers low power consumption, high integration

Dallas, Tex. — Texas Instruments Inc. has developed a sub-1 GHz radio-frequency (RF) transceiver, which offers low power consumption, high integration and high RF performance. The CC1101 targets low-power wireless applications in alarm and security, automatic meter reading, industrial monitoring and control, and home and building automation.

The CC1101 RF transceiver is an improved performance, code-compatible version of TI's CC1100 sub-1 GHz RF transceiver. Key enhancements include improved spurious response, better close-in phase noise, higher input saturation, improved output power ramping and extended frequency bands.

Designed for the industrial, scientific and medical (ISM) as well as short range device (SRD) frequency bands at 315, 433, 868 and 915 MHz, the CC1101 can also be programmed for operation at other frequencies in the 300-348 MHz, 387-464 MHz and 779-928 MHz bands. The device offers frequency band and modulation format support for compatibility with existing RF end equipment.

In addition, the CC1101 provides hardware support for package handling, data buffering, burst transmissions, clear channel assessment, link quality indication and wake-on radio. The main operating parameters and the 64-byte transmit/receive FIFOs can be controlled via an SPI interface. In a typical system, the CC1101 will be used with a microcontroller (MCU), such as TI's MSP430 ultra-low-power MCUs, and a few additional passive components.

Pricing: Suggested resale pricing for the CC1101 starts at $1.85 in quantities of 1,000. Availability: The CC1101 is available now in a QLP-20 package. Development kits for 433 MHz and 868/915 MHz frequency bands are available.
