CSR launches µEnergy™ platform for ultra low power connected devices
CSR today announced the launch of its first single-mode, single-chip Bluetooth low energy platform, CSR µEnergy, addressing the needs of ultra low power connected devices. The CSR µEnergy platform 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 CSR µEnergy Bluetooth low energy platform will enable ultra low power connectivity for applications previously limited by the power consumption, size constraints and complexity of other wireless standards.“T
CSR has a genuine understanding of OEMs’ priorities, and is the ideal company to deliver an easy-to-integrate, cost-effective Bluetooth low energy platform to the market.”
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.
Fiona Thomson of IMS Research said, “The technology will bring wireless connectivity to a whole new class of devices that have never used it before. The industry is at a key turning point with this technology right now and with the launch of the µEnergy platform of products, CSR is in a great position to drive this market forwards.”
Earlier this month the Bluetooth Special Interest Group (SIG) adopted the complete Bluetooth v4.0 specification, opening the door to commercial release of qualified Bluetooth low energy end products and CSR was one of the first companies to qualify its products to the new standard.
The CSR µEnergy platform has been optimised to support only Bluetooth low energy features, allowing products to be tiny, cost-effective and power-efficient. CSR’s chips can run for years on a single coin cell battery, and may be used in simple sensors such as a step counting foot pods, heart rate monitors or car keyfobs, as well as in more complex low power devices such as a watch that can control and display information from a mobile phone. The platform offers single-mode chips that complement CSR’s dual-mode offerings and provide a complete range of Bluetooth low energy solutions that will drive the development of this new market.
The CSR µEnergy platform, with its built-in processor, is designed for use in consumer products and requires no external processor to run customer applications. It includes four quadurature decoders to enable mouse and pointing devices, three analogue inputs for direct measurement of sensor, and digital serial connectors for external sensors and displays.
The chips each have direct antenna connections, can connect directly to a 3V coin cell or a pair of AAA batteries, and come with three pulse width modulation outputs for variable power control in applications such as lighting control or vibration motors. They can run in optimised sleep modes with currents as low as 600nA and chips can “wake” quickly in response to external input signals for applications such as remote controls. Both chips provide embedded support for keyboard scanning while “asleep” at less than 5µA.
CSR µEnergy is available in two package options. CSR1000 comes in a 32-pin 5x5x0.6mm QFN package. CSR1001, in a 56 pin 8x8x0.9mm QFN, provides extra pins for more complex products with a larger number of digital inputs, such as keyboards, remote control products or home information displays.
Both CSR1000 and CSR1001 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.
CSR’s µEnergy chips are available to lead customers now.
