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 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.
CC2540 features and benefits:
- One-chip integrated solution
- Lower cost
- Smaller physical size
- Flash-based
- Flexibility for developers
- Device firmware can be updated in the field if necessary
- Persistent data can be stored on-chip
- Complete solution
- TI provides IC, protocol stack, basic profile software and applications support
- Excellent RF performance
- Excellent link budget provides for long range
- Excellent selectivity provides for good coexistence with other 2.4-GHz devices
- Ultra-low power consumption
- Very long battery life
- Can use coin cells or alkaline batteries, no need for rechargeable batteries
- Pin-compatible with CC2530
- IEEE 802.15.4 (ZigBee®, RF4CE, 6LoWPAN) systems can use the same PCBs as Bluetooth low energy and proprietary 2.4-GHz systems
- Investments in hardware and software development can cross protocol boundaries
