Thus providing a BCM4325 Specifications compact small form factor solution with minimal external components to Host Interface SDIO (4 wire, 1 wire, SPI), UART drive the costs for mass volumes and allows for flexibility in size, form, Standard IEEE 802.11a, IEEE 802.11g and function of handheld devices. The BCM4325 is designed to address Data Rate 802.11a/g: 54, 48, 36, 24, 18, 12, 9, 6 Mbps; 802.11b: 11, 5.5, 2, 1 the needs of highly mobile devices that require minimal power Mbps consumption and reliable operation. Modulation OFDM, CCK, DQPSK, DBPSK Infrastructure and ad hoc 2.4 GHz-2.497 GHz, 4.9 GHz-5.85 GHz 11 for North America; 13 for Europe; 14 for Japan 802.1x; WEP, WEP2, WPA, WPA2 (Personal); TKIP and AES hardware acceleration, 802.11i The BCM4325 utilizes advanced design techniques and process technology to deliver the lowest active and idle power, extending the system battery life while maintaining consistent connectivity, and still provides a rich set of features. The BCM4325 implements the highly sophisticated InConcert radio coexistence algorithms and hardware mechanisms allowing for an extremely collaborative coexistence scheme along with coexistence support for external radios (such as GPS, WiMax, or Ultra Wide-Band radio technologies, as well as cellular radios) and a single shared Antenna. As a result, it enhances the overall quality for simultaneous voice, video, and data transmission on a handheld system while minimizing the footprint. The BCM4325 further integrates a power management unit simplifying the power topology on a system and allowing for operation directly from the handheld battery. It also integrates a CMOS power amplifier to meet Network Architectures Operating Frequencies Operating Channels Security Ordering Information * BCM4325GKFBG: IEEE802.11b/g 196-pin FBGA 7.5 mm x 7.5 mm package * BCM4325HKFBG: IEEE802.11a/b/g 196-pin FBGA 7.5 mm x 7.5 mm package * BCM4325GKWLG: IEEE802.11b/g wlCSP package * BCM4325HKWLG: IEEE802.11a/b/g wlCSP package Broadcom(R), the pulse logo, Connecting everything(R), and the Connecting everything logo are among the trademarks of Broadcom Corporation and/or its affiliates in the United States, certain other countries and/or the EU.
