Texas Instruments' CC1111 SoC integrates a sub-1 GHz radio-frequency (RF) transceiver with a USB controller to deliver a fast and easily-designed bridge between PCs and RF.
The CC1111, which TI says is the first chip of its type, combines the company's 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 chip is particularly useful when designed into a low-power sensor network utilizing TI's proprietary SimpliciTI network protocol.
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.
The CC1111 targets a range 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).
"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 vice president of TI's high-performance analog business.
SimpliciTI network protocol is a proprietary low-power RF protocol targeting simple, small RF networks (less than 256 nodes). It 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.
