CSR's second generation Bluetooth Smart platforms are designed to give greater flexibility in developing low-power wireless accessories. The CSR1010 and CSR1011, part of the CSR µEnergy range, will provide developers with end-to-end solutions for a range of devices, including HIDs such as wireless remote controls, mice and innovative ‘appcessories’. The news follows an announcement from Google and Bluetooth Special Interest Group that Android will include native support for Bluetooth Smart Ready and Bluetooth Smart devices in the next version of its operating system, meaning 75% of smartphones will be able to integrate seamlessly with a plethora of Bluetooth Smart Ready devices.
CSR1010 Development Kit
Bluetooth Smart enables low-power connectivity and basic data transfer for applications previously limited by the power consumption, size constraints and complexity of other wireless standards. CSR1010 and CSR1011 are based on CSR’s qualified Bluetooth Smart radio and offer a number of improvements on its first-generation platforms.
Offering 128KB of memory, the new platforms offer up to double the amount of memory on its previous version and six times the customer application space. This provides greater flexibility and an environment designed for more innovative and feature rich designs.
The new CSR platforms make use of the µEnergy hardware modem. The modem and the ultra-low power programmable IO controller can communicate with sensors and peripheral devices, without using the integrated microprocessor. This minimizes power consumption and reduces data transfer latency. These features ensure that system level power consumption is minimized, giving optimized performance with minimum development effort.
CSR has made the design process simpler by incorporating a single 50 ohm output pin, removing the need for a Balun and reducing the BOM and print circuit board design complexity. In addition, the on-chip switch mode power supply can be directly operated from a range of battery sources, without the need for inefficient external regulators.
CSR is also offering a software development kit, example applications and hardware layout examples to provide a flexible rapid development environment for Bluetooth Smart solutions. The company has the lowest cost of ownership for a Bluetooth Smart SDK and tools (including compilers) at $499, in comparison to an average price of $2,000 for a SDK license from other providers.
CSR also offers a ready to use set of reference designs for the CSR1010 and CSR1011 that are Bluetooth SIG certified and FCC and ETSI compliant.
