Key Features

Radio

! Common TX/RX terminals simplify external

matching and eliminates external antenna switch

! BIST minimises production test time. No external

trimming is required in production

! Full RF reference designs are available

! Bluetooth v2.0 + EDR Specification compliant

Transmitter

! +6dBm RF transmit power with level control from

on-chip 6-bit DAC over a dynamic range >30dB

! Class 2 and Class 3 support without the need for

an external power amplifier or TX/RX switch

! Class 1 support using external power amplifier, with

RF power controlled by an internal 8-bit DAC

! Supports DQPSK (2Mbps) and 8DPSK (3Mbps)

modulation

Receiver

! Integrated channel filters

! Digital demodulator for improved sensitivity and co-

channel rejection

! Real-time digitised RSSI available on HCI interface

! Fast AGC for enhanced dynamic range

! Supports DQPSK and 8DPSK modulation

! Channel classification

Synthesiser

! Fully integrated synthesizer requires no external

VCO varactor diode, resonator or loop filter

! Compatible with crystals between 8 and 40MHz (in

multiples of 250kHz) or an external clock

! Accepts 7.68, 14.44, 15.36, 16.2, 16.8, 19.2, 19.44,

19.68, 19.8 and 38.4MHz TCXO frequencies for

GSM and CDMA devices with sinusoidal or logic

level signals

Auxiliary Features

! Crystal oscillator with built-in digital trimming

! Power management includes digital shut down and

wake up commands with an integrated low-power

oscillator for ultra-low Park/Sniff/Hold mode

! Clock Request output to control an external clock

source

Auxiliary Features (continued)

! Device can run in low power modes from an

external 32KHz clock signal

! Auto Baud Rate setting for different TCXO

frequencies

! On-chip linear regulator, producing 1.8V output

from 2.2-4.2V input

! Power-on-reset cell detects low supply voltage

Baseband and Software

! Internal 48-KByte RAM, allows full-speed data

transfer, mixed voice and data, and full piconet

operation, including all medium rate preset types

! Logic for forward error correction, header error

control, access code correlation, CRC,

demodulation, encryption bit stream generation,

whitening and transmit pulse shaping. Supports all

Bluetooth v2.0 + EDR features including eSCO and

AFH

! Transcoders for A-law, μ-law and linear voice from

host and A-law,

μ-law and CVSD voice over air

Physical Interfaces

! Synchronous serial interface up to 4Mbaud for

system debugging

! UART interface with programmable baud rate up to

3Mbits/s with an optional bypass mode

! Full-speed USB v2.0 interface supports OHCI and

UHCI host interfaces

! Synchronous bi-directional serial programmable

audio interface

! Optional I2C™ compatible interfaces

! Optional 802.11 co-existence interfaces

Bluetooth Stack

CSR’s Bluetooth protocol stack runs on the on-chip

MCU in a variety of configurations:

! Standard HCI (UART or USB)

! Customised builds with embedded application code

Package Options

! 47-ball CSP 3.8 x 4.0 x 0.7mm
