As a contributing member and leader in the Bluetooth low energy technology space, TI is in a unique position to release single- and dual-mode chips in 2010 shortly after the final ratification of the specification.
TI’s BLE single-mode solution, the CC2540, is optimized to support Bluetooth low energy technology. The CC2540 offers up to +5-dBm output power with - 93-dBm receive sensitivity; has flexible memory options; and comes with a wide range of supported peripherals, including a power five-channel DMA, 21 GPIOs, two USARTs, Full Speed USB 2.0, on-board AES encryption/decryption engine and timers. The CC2540 comes as a 40-pin 6 x 6 QFN solution and is flash programmable.
As a total solution provider, TI not only has the hardware but provides the fully compliant software protocol stack for single-mode Bluetooth low energy technology, including master and slave and all required profile roles. The stack is power-optimized for optimal performance with all applications and includes tools, sample application code, profile support, drivers, development boards, documentation and everything else needed to easily develop a single-mode Bluetooth low energy solution with ease.
ZigBee Interface ZigBee health care products will be used in a variety of settings, including at home or in private outpatient residences, recreation centers, retirement communities and nursing homes. ZigBee has been selected by the Continua Alliance because ZigBee technology is targeted for low-power, battery-operated devices. Low-power sensing and monitoring is the sweet spot for 802.15.4 radios, which consume less power and provide longer battery life for medical devices.
The ZigBee Health Care (ZHC) technical working group has released the ZHC application profile for early adopters. This specification provides interoperability among various vendors. Such robust features let it coexist with other radio protocols and provide secure, low-packet error-rate data transfer.
TI provides a one-stop shop hardware reference design and software with the CC2530 or CC2520/ MSP430™ development kits, which are available at www.ti.com/lprf. For customers who do not want to design and certify their own radio platform, TI offers several module partners who provide FCC-certified ZigBee modules complete with antenna and software.
