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
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.
