Product Details
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. CSR1012 QFN provides everything required to create a Bluetooth low energy product with RF, baseband, MCU, qualified Bluetoothv4.1 specification stack and customer application running on a single IC.


CSR is the industry leader for Bluetooth low energy, also known as Bluetooth Smart. Bluetooth Smart enables connectivity and data transfer to leading smartphone, tablet and personal computing devices including Apple iPhone, iPad, iPod and Mac products and leading Android devices. Bluetooth low energy takes less time to make a connection than conventional Bluetooth wireless technology and can consume approximately 1/20th of the power of Bluetooth Basic Rate. CSR1012 QFN supports profiles for health and fitness sensors, watches, keyboards, mice and remote controls.

Typical Bluetooth Smart applications:
  • HID: keyboards, mice, touchpads, remote controls
  • Sports and fitness sensors: heart rate, runner speed and cadence, cycle speed and cadence
  • Health sensors: blood pressure, thermometer and glucose meters
  • Mobile accessories: watches, proximity tags, alert tags and camera controls
  • Smart home: heating control and lighting control
