BLUETOOTH® 2.0 + EDR SINGLE-CHIP HCI SOLUTION WITH INTEGRATED FM+RDS RADIO RECEIVER

BLUETOOTH FEATURES

• Monolithic single die integration of Bluetooth and FM Radio

• Bluetooth specification 2.0 +EDR compliant with all data packet types

and lengths supported

• Best-in-class Bluetooth radio based on the proven BCM2045 core

• Supports class 1 and 2 designs

• Integrated InConcert™ 2-wire as well as industry standard 3-wire

collaborative coexistence with WLAN systems

• No factory alignment required

• 5.5 Volt preregulator allows direct connect to lithium batteries

• Improved Bluetooth transport with 4-Mbaud UART

• Includes numerous enhancements for lower power dissipation

• ROM-based solution with flexible code patching

• Available in WLCSP 0.6 mm height and FPBGA <1 mm height

SUMMARY OF BENEFITS

• Bluetooth 2.0 +EDR compliant with easy migration to future specification

• Low external BOM cost and small area with 10 external RLC

components. The PCB foot print is < 35 mm2 area.

• Operates directly from a lithium battery or from fixed voltages down to

1.65 Volt

• Best-in-class RF performance for longest range and ease of system

integration

• Full featured FM system with RDS/RBDS capability

• FM system can operate independently from Bluetooth

• Highly flexible interfaces for control and data/audio routing

• Improved power dissipation for longer battery life

FM+RDS RADIO FEATURES

• 76-MHz to 108-MHz FM bands supported (US, Europe, and Japan)

• Excellent radio performance with 1 uV sensitivity for 26 dB (S+N)/N

• FM control through either BSC-compatible interface or Bluetooth HCI

• Signal dependant stereo/mono blending

• Signal dependant soft mute

• Auto search and tuning modes

• Audio silence detection

• RSSI, IF frequency, status indicators

• RDS and RBDS demodulator and decoder with filter and buffering

functions

• Operates from 32-kHz or reference clock inputs

• Flexible output interfaces including PCM, I2S, and analog stereo DAC

and drivers.

• Integrated FM and RDS receiver with only one external cap, one external

inductor and optional antenna matching

APPLICATIONS

• Mobile handsets and smart phones

• Personal digital assistants

• Mobile MP3 players
