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

FEATURES

FEATURES

• 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

• Fractional nPLL allows support for a wide range of reference

clock frequencies

• Security:

- WPA- and WPA2 (personal) for powerful encryption and

authentication

- 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

• Worldwide regulatory support—Global products supported

with worldwide homologated design

• Bluetooth Key Features

• 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

• Supports dual-A2DP for stereo sound

• Automatic frequency detection for standard crystal and TCXO

values

• General Features

• One driver software architecture for easy migration from

existing embedded WLAN and Bluetooth devices as well as

future devices

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

the internal switching regulator
