It is aimed at Bluetooth Smart sensor applications for consumer medical, sports and fitness, security, entertainment and home automation

Texas Instruments (TI) has announced its new CC2541 Bluetooth low energy system-on-chip (SoC) aimed at Bluetooth Smart sensor applications for consumer medical, sports and fitness, security, entertainment and home automation. The SoC offers a 33 percent reduction in power consumption compared to TI’s previous-generation CC2540 SoC when transmitting at 1 milliwatt output power, while maintaining robust RF performance, the company said.

The CC2541 is pin-to-pin compatible with the CC2540, allowing manufacturers to take advantage of the power savings through an easy migration of existing designs. An associated CC2541EMK development kit will also be available to further simplify and reduce design time for new Bluetooth Smart devices.

“We’re excited to see the advancements in the Bluetooth low energy space with Bluetooth Smart and Smart Ready devices already available and several about to hit the market. With the CC2541 SoC TI continues its commitment to offer low-power and easily-deployable Bluetooth low energy solutions to manufacturers. Our new CC2541 SoC adds to TI’s full system-solution, aimed at simplifying design and shrinking development time for Bluetooth Smart sensor applications,” said Sid Shaw, product marketing manager, low-power RF, TI.

“Bluetooth 4.0 technology is expanding into new markets as innovative use cases and products become available. We are pleased to see TI enabling longer battery life with the CC2541 SoC to further fuel interest in Bluetooth 4.0 technology and the growth of Bluetooth Smart and Smart Ready devices,” said Michael Foley,  executive director, Bluetooth SIG.
