IEEE 802.11x Key Features
■ IEEE 802.11ac compliant.
■ Single-stream spatial multiplexing up to 433.3 Mbps
■ Supports 20, 40, and 80 MHz channels with optional
SGI (256 QAM modulation).
■ Full IEEE 802.11a/b/g/n legacy compatibility with
■ Tx and Rx low-density parity check (LDPC) support
for improved range and power efficiency.
■ Supports Rx space-time block coding (STBC)
■ Supports IEEE 802.11ac/n beamforming.
■ On-chip power amplifiers and low-noise amplifiers for
■ Support for optional front-end modules (FEM) with
external PAs and LNAs
■ Shared Bluetooth and WLAN receive signal path elim-
inates the need for an external power splitter while
maintaining excellent sensitivity for both Bluetooth
■ Internal fractional nPLL allows support for a wide
range of reference clock frequencies
■ Supports IEEE 802.15.2 external coexistence inter-
face to optimize bandwidth utilization with other co-
located wireless technologies such as LTE, GPS, or
■ Supports standard SDIO v3.0 (including DDR50 mode
at 50 MHz and SDR104 mode at 208 MHz, 4-bit and
1-bit) host interfaces.
■ Backward compatible with SDIO v2.0 host interfaces.
■ PCIe mode (FCBGA package only) complies with PCI
Express base specification revision 3.0 compliant
Gen1 interface for ×1 lane and power management
■ Integrated ARMCR4™ processor with tightly coupled
memory for complete WLAN subsystem functionality,
minimizing the need to wake up the applications pro-
cessor for standard WLAN functions. This allows for
further minimization of power consumption, while
maintaining the ability to field upgrade with future fea-
tures. 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 Key Features
■ Complies with Bluetooth Core Specification Version
4.1 with provisions for supporting future specifica-
■ Bluetooth Class 1 or Class 2 transmitter operation.
■ Supports extended synchronous connections (eSCO),
for enhanced voice quality by allowing for retransmis-
sion of dropped packets.
■ Adaptive frequency hopping (AFH) for reducing radio
■ Interface support, host controller interface (HCI) using
a USB or high-speed UART interface and PCM for
■ USB 2.0 full-speed (12 Mbps) supported (FCFBGA
and WLCSP packages).
■ Low power consumption improves battery life of hand-
■ Supports multiple simultaneous Advanced Audio Dis-
tribution Profiles (A2DP) for stereo sound.
■ Automatic frequency detection for standard crystal
and TCXO values.
■ Supports serial flash interfaces.
