General Description
The _äìÉ`çêÉ»QJolj=mäìÖJåJdç» is a single
chip radio and baseband IC for Bluetooth 2.4GHz
systems. It is implemented in 0.18µm CMOS
technology.
BC41B143A contains 4Mbit of internal ROM memory.
When used with CSR Bluetooth stack, it provides a
fully compliant Bluetooth system to v2.0 + EDR of the
specification for data and voice.
BlueCore4-ROM Plug-n-Go has the same pinout and
electrical characteristics as available in
BlueCore4-Flash Plug-n-Go to enable development
of custom code before committing to ROM. It also has
the same pinout as BlueCore2-ROM Plug-n-Go and
BlueCore2-Flash Plug-n-Go to keep compatibility.

Keyboards
BlueCore4-ROM Plug-n-Go has been designed to
reduce the number of external components required
which ensures production costs are minimised. The
0.8mm pitch BlueCore4-ROM Plug-n-Go can be used
on either two or four layer PCB construction.
The device incorporates auto-calibration and built in
self test (BIST) routines to simplify development, type
approval and production test. All hardware and
device firmware is fully compliant with the Bluetooth
v2.0 + EDR specification.
