Texas Instruments Incorporated today introduced a new Sub-1 GHz RF Value Line family, offering developers low-cost connectivity solutions for sub-1 GHz RF applications such as remote controls, toys, home and building automation, and security systems. The Sub-1 GHz RF Value Line family launched with the CC115L transmitter, CC113L receiver and CC110L transceiver, all available immediately. In high volume, the line offers a complete, one-way RF link for less than USD $1. The new devices are based on TI’s Sub-1 GHz CC1101 RF technology, and are pin-, register- and code-compatible, as well as backwards compatible with existing sub-1 GHz systems.

“TI’s new Sub-1 GHz RF Value Line answers the market’s increasing need for simple, low-cost connectivity for applications that require both long battery life and long range wireless connection,” said Erling Simensen, product marketing manager, Low-Power RF, TI. “Designs based on the Sub-1GHz RF Value Line family not only ease connectivity integration efforts for engineers, but promise wireless connectivity for more of today’s cost-sensitive consumer applications.”

The CC11xLDK-868-915 and CC11xLEMK-433 development kits provide complete hardware performance testing and software development platforms for the new product family. The kits also offer new low-cost reference designs, with a compact PCB antenna for 433, 868, 915 MHz, 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.
