Key Features

1 Key Features

Radio

! Common TX/RX terminal simplifies external

matching; eliminates external antenna switch

! BIST minimises production test time. No external

trimming is required in production

! Full RF reference designs available

! Bluetooth v2.0 Specification compliant

! EDR v2.0.E.2 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

! Class1 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 synthesiser requires no external

VCO, varactor diode, resonator or loop filter

! Compatible with an external crystal or with an

external clock using sinusoidal or logic-level signals

! Accepts frequencies between 8 and 32MHz (in

multiples of 250kHz); additionally accepts 7.68,

14.44, 15.36, 16.2, 16.8, 19.2, 19.44, 19.68, 19.8

and 38.4MHz frequencies typically used in GSM

and CDMA devices

Auxiliary Features

! Crystal oscillator with built-in digital trimming

! Power management includes digital shut down,

wake up commands with an integrated low power

oscillator for ultra-low power Park/Sniff/Hold mode

! âClock requestâ output to control an external clock

Auxiliary Features (continued)

! On-chip linear regulator; 1.8V output from a 2.2 -

4.2V input

! Clock for low power mode can be either supplied

from an external 32kHz clock signal or an internal

oscillator

! Auto baud rate setting for different TCXO

frequencies

! Power-on-reset cell detects low supply voltage

! Arbitrary power supply sequencing permitted

! 8-bit ADC and DAC available to applications

Baseband and Software

! Internal 48Kbyte 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 features including eSCO and AFH

! Transcoders for A-law, Î¼-law and linear voice from

host and A-law, Î¼-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 I2Câ¢ compatible interfaces

! Audio PCM interface

! Optional co-existence interfaces

Bluetooth Stack

CSRâs Bluetooth Protocol Stack runs on the on-chip

MCU in a variety of configurations:

! Standard HCI (UART or USB)

! Fully embedded RFCOMM

! Customised builds with embedded application code

Package Options

! 84-ball VFBGA, 6 x 6mm x 1mm, 0.5mm pitch
