CSR µEnergy™

Description

CSR µEnergy unlocks the potential of the new Bluetooth low energy standard enabling the creation of a new market for tiny, cost-effective and power-efficient wireless consumer products. As CSR's first single-mode Bluetooth low energy solution, CSR µEnergy enables ultra low power connectivity and basic data transfer for applications previously limited by the power consumption, size constraints and complexity of other wireless standards. CSR's µEnergy platform provides 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 platform is available in two chip variants. The CSR1001 chip is optimised for keyboards and remote controls with dedicated hardware for keypad scanning. The CSR1000 offers a smaller package for fitness products, watches, mice and other sensors.
