FEATURES

? 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.
