Brief

SINGLE CHIP IEEE 802.11a/b/g MAC/BASEBAND/RADIO WITH INTEGRATED

BLUETOOTH^®2.1 + EDR AND FM RECEIVER FOR LOW-POWER MOBILE HANDSET

AND HANDHELD APPLICATIONS

F E A T U R E S

Bluetooth Key Features

•

F E A T U R E S

WLAN Key Features

•

Single-band 2.4-GHz 802.11b/g or dual-band 2.4-GHz and 5-

GHz 802.11a/b/g with Bluetooth 2.1 + EDR and FM receiver

Industry leading low-active transmit and receive power

consumption and ultra-low power in stand-by and idle modes

Supports IEEE 802.11d/e (WMM, QoS, WMM-PS), h, i, j

(upgrades available for k, r, w)

Supports IEEE 802.15.2 external three wire coexistence

scheme to support additional wireless technologies such as

GPS, WiMax, or UWB

Supports standard interfaces, SDIO v1.2 (1 bit and 4 bit), SPI,

and high speed UART, for easy migration from the Broadcom

2 chip solution (BCM4328 + BCM2048)

Integrated CPU with on-chip memory for a complete WLAN

subsystem minimizing the need to wake up the applications

processor

•

Bluetooth Specification version 2.1 + EDR (up to 3 Mbps)

compliant, with provisions for supporting future specifications

Supports extended synchronous connections (eSCO) for

enhanced voice quality by allowing for retransmission of

dropped packets

•

Adaptive frequency hopping (AFH), for reducing radio

frequency interference.

Interfaces support—Host controller interface (HCI) using a

high-speed UART interface and PCM for audio data

The FM unit supports BSC (Broadcom Serial Control) for

communications, stereo analog output, as well as I²S and

PCM interfaces.

•

Integrates the InConcert™ collaborative WLAN coexistence,

including the 802.15.2 three-wire coexistence support

Low-power consumption improves battery life of handheld

devices

76-MHz to 108-MHz FM bands and supports European Radio

Data Systems (RDS) and North American Radio Broadcast

Data Systems (RBDS) modulations

•

Fractional nPLL allows support for a wide range of reference

clock frequencies

Security:

WPA- and WPA2 (personal) for powerful encryption and

authentication

•

Supports dual-A2DP for stereo sound

Automatic frequency detection for standard crystal and TCXO

values

AES and TKIP in hardware for faster data encryption and

802.11i compatibility

Supports Cisco^®Compatible Extensions (CCX - CCX4.0)

SecureEasySetup™ for simple Wi-Fi setup and WPA2/

WPA security configuration

General Features

•

One driver software architecture for easy migration from

existing embedded WLAN and Bluetooth devices as well as

future devices

•

Worldwide regulatory support—Global products supported

with worldwide homologated design

•

Support battery voltage range from 2.3V to 5.5V supplies with

the internal switching regulator
