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.
