Texas Instruments Inc. (TI) has launched its Sub-1GHz RF Value Line family that offers developers low-cost connectivity solutions for sub-1GHz RF applications such as remote controls, toys, home and building automation, and security systems. With the launch of the new series is the release of the CC115L transmitter, CC113L receiver and CC110L transceiver.

The devices are based on TI's sub-1GHz CC1101 RF technology. They are pin-, register- and code-compatible, as well as backwards compatible with existing sub-1GHz systems.

According to TI, the CC11xLDK-868-915 and CC11xLEMK-433 development kits provide complete hardware performance testing and software development platforms for the product family. The kits also offer low-cost reference designs, with a compact PCB antenna for 433, 868, 915MHz, featuring a reduced component count and complete design ready for FCC and ETSI certification. The small-size, compact PCB helix antenna represents only a quarter of the size of previous PCB antennas, and is useful for applications requiring high antenna efficiency in a compact area.

The sub-1GHz RF Value Line family offer seamless integration with CC1190 range extender and gives up to 27dBm output power and -120dBm sensitivity, and up to 20dBm output power without frequency hopping (FHSS) under FCC. It is compatible with CC1190 range extender, MSP430 Value Line microcontroller, and TPS62730 step-down converter with bypass mode for ultra low power wireless applications.

The solution is packaged in a ROHS-compliant, 4 x 4mm QFN-32. Pricing starts at $0.75 in 1,000-unit quantities.

The CC11xLDK-868-915 development kit is available for $299. An additional CC11xLEMK-433 development kit is available for $99.
