BCM4319XKUBGT Datasheet, PDF (3/84 Pages) Cypress Semiconductor – Single-Chip IEEE 802.11™ a/b/g/n MAC/Baseband/ Radio with Integrated SDIO and USB Interfaces

FEATURES
IEEE 802.11x Key Features
• Dual band 2.4 GHz and 5 GHz 802.11 a/b/g/n.
• Single stream 802.11n support for both 20 MHz
and 40 MHz channels provides PHY layer rates up
to MCS7 (150 Mbps) for typical upper layer
throughput in excess of 70 Mbps.
• Integrated CMOS power amplifiers deliver greater
than 20 dBm of linear output power
• Integrated ARM^® Cortex-M3 processor and on-
chip memory for complete WLAN subsystem
functionality minimizing the need to wake up the
applications processor for standard WLAN
functions. This allows for further minimization of
power consumption, while maintaining the
capability to field upgrade with future features.
• Provides for the following security features:
• WPA™ and WPA2™ (Personal) support for
powerful encryption and authentication
• AES and TKIP acceleration hardware for faster
data encryption and 802.11i compatibility
• Cisco^® Compatible Extension (CCX, CCX 2.0,
CCX 3.0, CCX 4.0) certified
• SecureEasySetup™ for simple Wi-Fi^® setup
and WPA2/WPA security configuration
• Provides IEEE 802.11d, e (WMM, QoS,
WMM-PS), h, i, j (k, r, and w in the future).
• Supports IEEE 802.15.2 external 3-wire and
4-wire coexistence schemes to support additional
co-located wireless technologies such as
Bluetooth^® GPS, WiMax or UWB.
• Provides an ultra-small form factor solution and
ultralow power consumption to support low-cost
requirements.
• Wi-Fi Protected Setup (WPS).
• Internal fractional nPLL allows support for a wide
range of reference clock frequencies.
• Worldwide regulatory support: Global products
supported with worldwide homologated design.
USB 2.0 Key Features
• Support for high speed 480 Mbit/s or full speed
12 Mbit/s operation
• Endpoint management unit
• USB 2.0 protocol engine
• Separate endpoint packet buffers with a 512-byte
FIFO buffer in each direction
• Host-to-device communication for bulk, control,
and interrupt transfers
SDIO Key Features
• Supports standard SDIO V2.0 (4-bit and 1-bit),
and SPI mode
• SDIO clock rates up to 50 MHz
