Features

IEEE 802.11x Key Features

■ Single-band 2.4 GHz IEEE 802.11b/g/n.

■ Support for 2.4 GHz Cypress TurboQAM® data rates (256-

QAM) and 20 MHz channel bandwidth.

■ Integrated iTR switch supports a single 2.4 GHz antenna.

■ Supports explicit IEEE 802.11n transmit beamforming.

■ Tx and Rx low-density parity check (LDPC) support for

improved range and power efficiency.

■ Supports standard SDIO v2.0 and gSPI host interfaces.

■ Supports space-time block coding (STBC) in the receiver.

■ Integrated ARM Cortex-M3 processor and on-chip 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 512 KB SRAM and

640 KB ROM.

■ OneDriver™ software architecture for easy migration from

existing embedded WLAN.

General Features

■ Support diversity antenna.

■ Supports a battery voltage range from 3.0V to 4.8V with an

internal switching regulator.

■ Programmable dynamic power management.

■ 4 Kbit one-time programmable (OTP) memory for storing board

parameters.

■ Can be routed on low-cost 1-x-1 PCB stack-ups.

■ 74-ball WLBGA package (4.87 mm × 2.87 mm, 0.4 mm pitch).

■ Security:

❐ WPA and WPA2 (Personal) support for powerful encryption

and authentication.

❐ AES in WLAN hardware for faster data encryption and IEEE

802.11i compatibility.

❐ Reference WLAN subsystem provides Cisco Compatible Ex-

tensions (CCX, CCX 2.0, CCX 3.0, CCX 4.0, CCX 5.0).

❐ Reference WLAN subsystem provides Wi-Fi protected setup

(WPS).

■ Worldwide regulatory support: Global products supported with

worldwide homologated design.
