FEATURES
POWER MANAGEMENT
• Highly integrated one-chip MAC, baseband, dual-band 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 BCM4326 single-chip}
IEEE 802.11b/g™ 2.4-GHz 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
