Single-band 2.4-GHz 802.11b/g or dual-band 2.4-GHz and 5-
GHz 802.11a/b/g with Bluetooth 2.1 + EDR and FM receiver
Industry leading low-active transmit and receive power
consumption and ultra-low power in stand-by and idle modes
Supports IEEE 802.11d/e (WMM, QoS, WMM-PS), h, i, j
(upgrades available for k, r, w)
Supports IEEE 802.15.2 external three wire coexistence
scheme to support additional wireless technologies such as
GPS, WiMax, or UWB
Supports standard interfaces, SDIO v1.2 (1 bit and 4 bit), SPI,
and high speed UART, for easy migration from the Broadcom
2 chip solution (BCM4328 + BCM2048)
Integrated CPU with on-chip memory for a complete WLAN
subsystem minimizing the need to wake up the applications
processor
•
Bluetooth Specification version 2.1 + EDR (up to 3 Mbps)
compliant, with provisions for supporting future specifications
Supports extended synchronous connections (eSCO) for
enhanced voice quality by allowing for retransmission of
dropped packets
•
•
•
•
Adaptive frequency hopping (AFH), for reducing radio
frequency interference.
Interfaces support—Host controller interface (HCI) using a
high-speed UART interface and PCM for audio data
The FM unit supports BSC (Broadcom Serial Control) for
communications, stereo analog output, as well as I²S and
PCM interfaces.
