General Description
CSR1012 QFN is a CSR µEnergy platform device.
CSR µEnergy are CSR's single-mode Bluetooth low
energy products for the Bluetooth Smart market.
CSR1012 QFN is a small footprint variant of CSR1010
QFN.
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 Bluetooth
v4.1 specification stack and customer application
running on a single IC.

Applications
■
Building an ecosystem using Bluetooth low energy
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 1/20
th
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
