FEATURES

IEEE 802.11X Key Features

• IEEE 802.11ac Draft compliant.

• Dual–stream spatial multiplexing up to

867 Mbps data rate.

• Supports 20, 40, and 80 MHz channels with

optional SGI (256 QAM modulation).

• Full IEEE 802.11a/b/g/n legacy compatibility

with enhanced performance.

• TX and RX low–density parity check (LDPC)

support for improved range and power

efficiency.

• Supports IEEE 802.11ac/n beamforming.

• On–chip power amplifiers and low–noise

amplifiers for both bands.

• Supports various RF front–end architectures

including:

– Two antennas with one each dedicated to

Bluetooth and WLAN.

– Two antennas with WLAN diversity and a

shared Bluetooth antenna.

• Shared Bluetooth and WLAN receive signal

path eliminates the need for an external

power splitter while maintaining excellent

sensitivity for both Bluetooth and WLAN.

• Internal fractional nPLL allows support for a

wide range of reference clock frequencies

• Supports IEEE 802.15.2 external

coexistence interface to optimize bandwidth

utilization with other co–located wireless.

technologies such as LTE or GPS.

• Supports standard SDIO v3.0 (up to SDR104

mode at 208 MHz, 4–bit and 1-bit) host

interfaces.

• Backward compatible with SDIO v2.0 host

interfaces.

• Alternative host interface supports HSIC v1.0

• PCIe mode complies with PCI Express base

specification revision 3.0 for ×1 lane and power

management running at Gen1 speeds.

• Integrated ARMCR4™ processor with tightly coupled

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 ability to field upgrade with future

features. On–chip memory includes 768 KB SRAM and

640 KB ROM.

• OneDriver™ software architecture for easy migration

from existing embedded WLAN and Bluetooth devices

as well as future devices.

Bluetooth and FM Key Features

• Complies with Bluetooth Core Specification Version 4.1

with provisions for supporting future specifications.

• Bluetooth Class 1 or Class 2 transmitter operation.

• 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.

• Interface support, host controller interface (HCI) using a

USB or high–speed UART interface and PCM for audio

data.

• USB 2.0 full–speed (12 Mbps) supported for Bluetooth.

• The FM unit supports HCI for communication.

• Low power consumption improves battery life of

handheld devices.

• FM receiver: 65 MHz to 108 MHz FM bands; supports

the European radio data systems (RDS) and the North

American radio broadcast data system (RBDS)

standards.

• Supports multiple simultaneous Advanced Audio

Distribution Profiles (A2DP) for stereo sound.

• Automatic frequency detection for standard crystal and

TCXO values.

• Supports serial flash interfaces.
