General Description
CSR1011 QFN is a CSR µEnergy platform device.
CSR µEnergy are CSR's single-mode Bluetooth low
energy products for the Bluetooth Smart market.
CSR1011 QFN increases application code and data
space for greater application development flexibility.
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. The CSR
μEnergy platform provides everything required to
create a Bluetooth low energy product with RF,
baseband, MCU, qualified Bluetooth v4.0 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. CSR1011 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
