Finalist: CC1111 wireless-sensor SOC (Texas Instruments)
 Connectivity is often as important as the application-specific features in an end product or an IC. Wireless networks can connect things as simple as light switches and heating or air-conditioning controls. Low cost is the key to making such wireless-sensor networks plausible, and nothing drives down cost as well as an SOC (system on chip) dedicated to the task at hand. Texas Instruments targets just such applications with its less-than-1-GHz CC1111 RF SOC. The CC1111 integrates a microcontroller, a USB interface for PC connectivity, flash memory, and the RF transceiver that works in the unlicensed spectrum below 1-Ghz. TI also offers a 2.4-GHz version of the IC.
With the CC111, TI targets low-power wireless applications, such as alarm and security systems, automatic meter reading, industrial monitoring and control, home and building automation, and remote controls. The company also offers the complementary SimpliciTI network protocol and a family of ICs for endpoints in the target applications. The radio can transmit data at 1.2 to 500 kbps and integrates an encryption/decryption coprocessor for applications that require data security. The device consumes a miserly 0.3 μA in sleep mode.
