AirForce One™ SINGLE-CHIP IEEE 802.11b/g™

MAC/BASEBAND/RADIO WITH INTEGRATED CPU

FEATURES

POWER MANAGEMENT

• 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® coexistence algorithms with

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® devices,

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.

AirForce™ FEATURE SET

• SmartRadio™: continuous calibration reduces test time and

improves manufacturability.

• Xpress™ technology: standards-based frame bursting improves

overall network efficiency.

• 125 High Speed Mode™: standards-plus performance

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

encryption and authentication

• AES and TKIP in hardware for faster data encryption and

IEEE 802.11i™ compatibility

• Cisco® Compatible Extensions (CCX, CCX2.0, CCX3.0,

CCX4.0) certified

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

security configuration

• 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.
