Bluetooth low energy holds the promise of wireless connectivity everywhere, to everything
Bluetooth low energy is an emerging open standard under development by the Bluetooth SIG that will offer state-of-the-art communication technology in the sports and fitness, medical, watch, home and office and other consumer markets. Bluetooth low energy technology will offer a low-cost, low-power interface to your cellular phone, laptop, or other Bluetooth enabled product. Though Bluetooth low energy is a separate standard from Bluetooth, it can be easily integrated into existing Bluetooth chipsets and is poised for extensive roll-out in cellular phones and Bluetooth-enabled devices in 2010.
Why Bluetooth low energy:
Compared to classic Bluetooth-enabled products, Bluetooth low energy enables the use of coin cells and energy harvesting solutions where applications can operate more than a year on a tiny button cell battery without recharging.
Dual-mode devices enable connectivity to cell phones as Bluetooth low energy is easily integrated with traditional Bluetooth technology.
Single-mode devices only support Bluetooth low energy and is optimized for low-power, low-cost solutions.
As the leader in low-power RF solutions, TI is pleased to be an active contributor to the emerging Bluetooth low energy standard. The CC2540, which is the first operational single-mode, system-on-chip to support Bluetooth low energy, is currently sampling to selected customers and will be available for the mass market early 2010.
Applications can be written directly onto the CC2540, which supports both analog and digital peripherals, eliminating the need for a second costly microprocessor. Alternately, the CC2540 can be integrated into an existing design as a network processor device, with a host processor running the core application and the CC2540 providing Bluetooth low energy communication.
Why Bluetooth low energy from TI:
TI provides both dual-mode and single-mode solutions
TI has demonstrated the world’s first single-chip (controller, host and application on one 6x6mm device) single-mode Bluetooth low energy device
TI provides a total solution: RF ICs, protocol stacks, profile software, application examples, development kits
TI has announced a $99 single-mode Bluetooth low energy development kit and a royalty-free protocol stack
Taking advantage of this Bluetooth dual-mode infrastructure, single-mode Bluetooth devices like TI’s CC2540 offer a low-cost, low-power solution that easily integrates into existing or new products.
