CSR has announced the launch of its first single-mode, single-chip Bluetooth low-power platform, CSR μEnergy, to meet the needs of ultra-low-power connected devices. The CSR μEnergy platform will provide everything needed to create Bluetooth low energy products, including RF, baseband, microcontroller, standard Bluetooth 4.0 protocol stack, and client applications running on the same chip. The CSR μEnergy Bluetooth low energy platform enables ultra low power connections for applications previously limited by power, size and other wireless standard complexity.

Anthony Murray, senior vice president of CSR Audio and Consumer Business, pointed out: "The CSR μEnergy platform has tapped the potential of Bluetooth low energy standards and is a major advancement in consumer wireless technology. Bluetooth low energy technology will be proprietary and difficult to adopt. The standard decentralized market brings a new choice and is deployed in a variety of everyday devices to change the way people interact with the local environment. The ultra-low-power CSR μEnergy platform will bring more connectivity to mobile phones, TVs, PCs. , media player or tablet accessories, so that consumers can experience the charm of these services at home or through the products they carry with them. Bluetooth low energy sensors in consumer products can change their users according to their needs Behavior, and tags enable consumers to search for and locate products and services around them. CSR understands the needs of OEMs and is the ideal enterprise to provide the market with an easy-to-integrate, cost-effective Bluetooth low-power platform."
Analysts predict that Bluetooth low energy will drive new segments of wireless accessories or wireless products, including remote controls, health and wellness equipment, PC human interface devices, clocks, keyless entry systems, advertising, indoor positioning, intelligence Energy equipment and adjacent labels.
Fiona Thomson of IMS Research points out: "This technology brings the capabilities of wirelessly connected devices to an unprecedented level. It is because of this technology that the industry is at a critical turning point. With the introduction of the μEnergy product platform, CSR It has also gained a favorable position in promoting the development of this market."
Earlier this month, the Bluetooth Technology Alliance SIG adopted the full Bluetooth 4.0 version of the specification, opening the commercial path to standard Bluetooth low-power products. At the same time, CSR became one of the first companies to offer products that meet the new standards.
The optimized CSR μEnergy platform only supports Bluetooth low energy, making the product smaller, less expensive and more power efficient. CSR chips can be used for a few years with just one button battery, for simple sensors such as pedometers, heart rate monitors, car keys, and more complex low-power devices such as control and display of cell phone information. Watches, etc. The single-mode chip provided by the platform complements the CSR dual-mode product to form a complete Bluetooth low-power solution. It will further promote the development of this emerging market.
The CSR μEnergy platform and its embedded processor are primarily designed for consumer products and require no external processor to run client applications. It contains four quadrature decoders for driving the mouse and pointing devices, three analog inputs for sensor direct measurement, and a digital string connector for external sensors and displays.
Each chip is directly connected to the antenna, can be directly connected to a 3V button battery or two 7-cell batteries, and provides 3 pulse width modulation output for variable power control in some applications, such as lighting control or Vibration motor. The chip can operate in an optimized sleep mode with operating currents as low as 600nA and can be quickly recovered from sleep to meet external input signal needs, such as remote control applications. Both chips are embedded to support keyboard scanning with a sleep current of less than 5μA.
CSR μEnergy is available in two optional packages. The CSR1000 is available in a 32-pin 5x5x0.6mm QFN package. The CSR1001 is available in a 56-pin 8x8x0.9mm QFN package. It provides additional pins for more complex products with a large number of digital inputs, such as keyboards, remote controls and home information displays.
Both the CSR1000 and CSR1001 are capable of master-slave configuration, using the new standard Bluetooth 4.0 host stack from CSR to provide complete GAP, L2CAP, Security Manager, Attribute Protocol (ATT) and Common Attribute Specification (GATT). These devices can run a complete client application on the chip by using an embedded 16-bit microprocessor.
The CSR μEnergy chip is available now.
Now it's easy to have a
magical star ceiling in your own home, with our high quality fiber optic star
kit. Unlike most companies offering star ceiling kits, we actually make our own
fiber and components, and our products are certified to exacting CE and ROHS
standards. So you can be sure you're getting the best!
Since we design and manufacture our own fiber optic products, our star ceilings
are higher quality than those offered elsewhere. As well as high quality
components, they come with mixed diameter fibers for a 3D 'near and far'
effect, and also have small fittings to give you a neat finish in the ceiling
or wall where you're installing the star lights.
Our fittings allow the fiber to pass all the way through to the other side of
the material, exposing the fiber end and covering up any ragged edges from
drilling. This allows more light through, giving you a more intense star
effect. The bare fibers can also be used on their own if you prefer.
