Single-Chip Bluetooth Platform Has Four Decoders And Direct Antenna Connections

Cambridge, U.K. and San Jose, Calif., U.S.: CSR has developed a single-mode, single-chip Bluetooth low-energy platform that will provide everything required to create a Bluetooth low-energy product with RF, baseband, microcontroller, qualified Bluetooth v4.0 stack, and customer application running on a single chip, the company says.

Analysts predict that Bluetooth low energy will enable new markets for wireless accessories or wireless-enabled products including remote controls, health and wellbeing devices, PC human interface devices, watches, automotive keyless entry, advertising, indoor location, smart-energy appliances, and proximity tagging.

The Bluetooth Special Interest Group (SIG) recently adopted the complete Bluetooth v4.0 specification, opening the door to the commercial release of qualified Bluetooth low-energy end products. CSR was one of the first companies to qualify its products to the new standard.

The CSR µEnergy platform includes four quadurature decoders to enable mouse and pointing devices, three analog inputs for direct measurement of sensors, and digital serial connectors for external sensors and displays.

The chips each have direct antenna connections. Also, they can connect directly to a 3-V coin cell or a pair of AAA batteries. They come with three pulse-width modulation outputs for variable power control in applications such as lighting control or vibration motors. And, they can run in optimised sleep modes with currents as low as 600 nA.

CSR µEnergy is available in two options. The CSR1000 and CSR1001 both can act as a master or slave using CSR’s recently qualified Bluetooth v4.0 host stack providing complete Generic Access Profile (GAP), L2CAP, Security Manager, Attribute Protocol (ATT), and Generic Attribute Profile (GATT). These devices enable customers to run their complete application on chip using the embedded 16-bit microprocessor.
