Features
IEEE 802.11x Key Features
■ IEEE 802.11ac compliant.
■ Support for MCS8 VHT20 in 20 MHz channels for up to 86.7
Mbps data.
■ 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.
■ On-chip power amplifiers and low-noise amplifiers for both
bands.
■ Support for optional front-end modules (FEM) with external
PAs and LNAs.
■ Supports integrated T/R switch for 2.4 GHz band.
■ Supports RF front-end architecture with a single dual-band
antenna shared between Bluetooth and WLAN for lowest
system cost.
■ Shared Bluetooth and WLAN receive signal path eliminates
the need for an external power splitter while maintaining
excellent sensitivity for both Bluetooth and WLAN.
■ Supports IEEE 802.15.2 external coexistence interface to
optimize bandwidth utilization with other co-located wireless
technologies such as LTE or ZigBee.
■ Supports standard SDIO v3.0 (including DDR50 mode at
50 MHz and SDR104 mode at 208 MHz, 4-bit and 1-bit) interfaces.
■ Backward compatible with SDIO v2.0 host interfaces.
■ USB 2.0 high-speed (480 Mbps) with integrated USB hub.
■ Intergrated Arm Cortex R4 processor and with tightly coupled
memory for complete WLAN subsystem functionality and
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 for WLAN
core includes 896 KB RAM and 896 KB ROM.
■ Integrated Arm Cortex M3 processor that runs software from
the Link Control (LC) to the Host Controller Interface (HCI)
layer for Bluetooth.The Arm core is paired with a memory unit
that contains 1088 KB of ROM and 384 KB of RAM.
■ OneDriver™ software architecture for easy migration from
existing embedded WLAN and Bluetooth devices as well as
future devices.
