Features
IEEE 802.11x Key Features
■ IEEE 802.11ac compliant.
■ Single-stream spatial multiplexing up to 433.3
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) sup-
port 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 amplifi-
ers for both bands.
■ Support for optional front-end modules (FEM)
with external PAs and LNAs
■ 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, GPS, or WiMAX
■ Supports standard SDIO v3.0 (including DDR50
mode at 50 MHz and SDR104 mode at 208 MHz,
4-bit and 1-bit), and gSPI (48 MHz) host inter-
faces.
■ Backward compatible with SDIO v2.0 host inter-
faces.

■
Integrated ARMCR4
™
processor with tightly cou-
pled memory for complete WLAN subsystem
functionality, minimizing the need to wake up the
applications processor for standard WLAN func-
tions. 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 Key Features
■ Complies with Bluetooth Core Specification Ver-
sion 4.1 for automotive and industrial applications
with provisions for supporting future specifica-
tions.
■ Bluetooth Class 1 or Class 2 transmitter opera-
tion.
■ 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 high-speed UART interface and PCM for
audio data.
■ Supports multiple simultaneous Advanced Audio
Distribution Profiles (A2DP) for stereo sound.
■ Automatic frequency detection for standard crys-
tal and TCXO values.
■ Supports low energy host wake-up for long term
system sleep capability.
