BlueCore01b is a single chip radio and baseband IC
for Bluetooth 2.4GHz radios, and is implemented in
CMOS technology.
When used with external flash containing the CSR
Bluetooth software stack, it provides a fully compliant
Bluetooth system for data and voice communications.

The design is optimised to require very few external
RF components to facilitate rapid design of the applica-
tion printed wiring board, and therefore the fastest pos-
sible time to market and lowest overall cost.
A low intermediate frequency receiver is utilised to
allow on-chip channel filtering. All hardware is fully
compliant with the Bluetooth specification.
The device operates from a regulated supply in the
range 2.7V to 3.3V and is available in an 81-ball BGA
package.
Device Features
Compliant to Bluetooth specification V1.1
Small footprint in 8mm x 8mm 81-ball BGA
Fully integrated RF block with no external
adjustments or trim
USB V1.1 compliant
Qualified Bluetooth firmware included
Extensive built-in-self-test to minimise end
product final test time
RF reference designs available
Low power consumption/optimisation
Support for up to 7 slaves
