Texas Instruments has introduced what it says is the the industry's first sub-1 GHz radio-frequency (RF) system-on-chip (SoC) with an integrated USB controller, enabling a fast and easy bridge between PCs and RF. The CC1111 combines the excellent performance of TI's state-of-the-art RF transceiver (CC1101) with an enhanced 8051 microcontroller (MCU), 8/16/32 kB of in-system programmable flash memory and a full-speed USB controller for improved low-power wireless sensor networking.

The breakthrough integration of the CC1111, combined with our SimpliciTIT network protocol, allows customers to develop state-of-the-art wireless sensor networks with smaller PCB size, lower
overall system cost and faster time-to-market said Art George, senior vice president of TI's high-performance analog business. By delivering innovative low-power RF technology, support and software, TI gives customers complete RF solutions to achieve next-generation performance
in both sub-1 GHz and 2.4 GHz frequency ranges.

The CC1111 targets a wide variety of low-power wireless applications including alarm and security systems, automatic meter reading, industrial monitoring and control, home and building automation and remote controls. The CC1111 is pin- and register-compatible with the CC1110 (sub-1 GHz SoC), CC2511 (2.4 GHz SoC with USB) and CC2510 (2.4 GHz SoC).

Additional features include embedded 128-bit AES security coprocessor, excellent receiver selectivity and blocking performance, high sensitivity, programmable data rate of up to 500 kBaud, wide supply
voltage range (2.0 V to 3.6 V) and four flexible power modes for reduced power consumption.

SimpliciTI network protocol is a proprietary low-power RF protocol targeting simple, small RF networks (less than 256 nodes). This protocol requires minimal MCU resources and was designed for easy implementation on the CC1110/11 and CC2510/11 SoCs or MSP430 ultra-low-power MCUs
combined with CC1100 and CC2500 transceivers. SimpliciTI network protocol is provided as source code under a free license, without royalties, and can be downloaded at www.ti.com/simpliciti.

The CC1111 is available now from TI and its authorized distributors in a 6-mm x 6-mm QFN-36 package. Suggested resale pricing for the CC1111 starts at $4.65 in 1,000-piece quantities. Start your development today with a comprehensive development kit (CC1110-CC1111DK).
