CC1111

Texas Instruments Inc. has introduced what it touts as the industry's first sub-1GHz RF 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 RF transceiver (CC1101) with an enhanced 8051 MCU, 8/16/32Kbytes 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 SimpliciTI 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 VP 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-1GHz and 2.4GHz 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-1GHz SoC), CC2511 (2.4GHz SoC with USB) and CC2510 (2.4GHz SoC).

Additional features include embedded 128bit AES security coprocessor, excellent receiver selectivity and blocking performance, high sensitivity, programmable data rate of up to 500 kBaud, wide supply voltage range (2V to 3.6V) 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 ultralow-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 TI's Web site.

The CC1111 is available now in a 6mm x 6mm QFN-36 package. Suggested resale pricing starts at $4.65 in 1,000-piece quantities. A comprehensive development kit (CC1110-CC1111DK) is also available.
