General Description
The CSR8811 WLCSP is a product from CSR's
Connectivity Centre. It is a single-chip radio and
baseband IC for Bluetooth 2.4GHz systems including
EDR to 3Mbits/s and Bluetooth low energy.
CSR8811 WLCSP's dual-mode radio enables it to
connect to the billions of Bluetooth products already on
the market, as well as a new generation of Bluetooth low
energy devices.
When used with CSR Synergy^® Software and a CSR
UniFi ^® wireless chip, CSR8811 WLCSP provides a
system fully qualifiable to the Bluetooth v4.1 for faster
file transfer.
This family of Bluetooth products includes:
■ _{CSR8311 A12 for automotive applications}
Products requiring a standalone Bluetooth low energy
radio should use products of the CSR101x™ family.

Applications
Consumer electronics devices, for example:
■ _{Portable navigation devices}
■ Point of sale terminals
■ _{Personal media players}
CSR designed CSR8811 WLCSP to reduce PCB area
and the number of external components:
■ _{The high-power Class 1 Bluetooth transmitter}
removes the requirement for external amplification.
■ The balun is integrated, which results in a single-
ended 50Ω port that does not require additional
matching components.
■ _{Integrated LDOs, with minimum decoupling}
components required, allow the chip to be operated
directly from a battery or regulated supply.
■ _{No requirement for external inductors.}
This ensures that production costs are minimised.
The device incorporates auto-calibration and BIST
routines to simplify development, type approval and
production test.
To improve the performance of both Bluetooth and
IEEE 802.11b/g/n co-located systems a wide range of
coexistence features are supported.
