General Description
Applications
_`OJolj=is a single chip radio and
baseband chip for Bluetooth wireless technology
2.4GHz systems.
It is implemented in 0.18
m CMOS technology.
BlueCore2-ROM has the same pinout and
electrical characteristics as available in
BlueCore2-Flash to enable development of
custom code before committing to ROM.
The 4Mbit ROM is metal programmable, which
enables a six week turn-around from approval of
firmware to production samples.
Cellular Handsets
Personal Digital Assistants
Mice
Keyboards
High volume, cost sensitive production
BlueCore2-ROM has been designed to reduce the number
of external components required which ensures
production costs are minimised.

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 specification v1.1.
