•

Highly integrated one-chip MAC, baseband, direct conversion

radio, and ARM7™ processor for low-power embedded

applications.

Designed to meet exacting requirements of mobile devices,

including small form factor, ultra-low power consumption, and low

cost.

Footprint-compatible with BCM4328 single-chip

IEEE 802.11a/b/g™ dual-band MAC/baseband/radio with

integrated CPU.

Support for multiple interface options popular in embedded

designs: SDIO (1- and 4-bit) and USB 2.0.

Embedded ARM7 CPU that executes the full WLAN driver,

eliminating the need for complicated wireless LAN integration into

the host platform.

Portable streamlined software interface for easy migration to

embedded operating systems.

Support for advanced Bluetooth

hardware interface targeted at voice and multimedia applications.

On-chip boot ROM and SRAM for a complete WLAN subsystem.

Internal fractional nPLL allows support for a wide range of

reference clock frequencies.

Requires only a single 3.3V external supply voltage.

3.3V/1.8V-tolerant I/O.

Support for 2.5V–5.5V VBAT supplies with a single external

switching regulator.

On-chip UART and JTAG interfaces for ease of debugging.

Available in FBGA (0.5-mm pitch) and WLCSP (0.25-mm pitch)

packages.

Integrated power amplifier for medium-transmit power embedded

devices; interface to external power amplifier for high-power

applications.

DSP architecture reduces the power required to transmit data by

30 percent.

Low power consumption improves battery life of Wi-Fi

including handheld devices and consumer electronics.

Integrated CPU; designed for low CPU usage to ensure that

system resources are available for handheld applications.

Dynamic power management through on-board PMU.

Only a single 3.3V external supply voltage is required.

SmartRadio™: continuous calibration reduces test time and

improves manufacturability.

Xpress™ technology: standards-based frame bursting improves

overall network efficiency.

125 High Speed M ode™: standards-plus perform ance

enhancement delivers best real-world performance when both

client and AP support high-speed mode.

Enhanced BroadRange™ technology: standards-compliant

features increase receive sensitivity to improve range and distance

performance at higher data rates.

Security:

• WPA™ (personal) and WPA2™ (personal) certified for powerful

• AES and TKIP in hardware for faster data encryption and

• Cisco

• SecureEasySetup™ for simple Wi-Fi setup and WPA2/WPA

Worldwide support: global products supported with worldwide

homologated design.

OneDriver™: single driver across all platforms—IEEE 802.11a/

b/g/n—simplifies driver update process and improves customer

satisfaction.
