CYW4354

Features

IEEE 802.11X Key Features

■ IEEE 802.11ac Draft compliant.

■ Dual–stream spatial multiplexing up to 867 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) support for

improved range and power efficiency.

■ Supports IEEE 802.11ac/n beamforming.

■ On–chip power amplifiers and low–noise amplifiers for both

bands.

■ Supports various RF front–end architectures including:

❐ Two antennas with one each dedicated to Bluetooth and

WLAN.

❐ Two antennas with WLAN diversity and a shared Bluetooth

antenna.

■ 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 or GPS.

■ Supports standard SDIO v3.0 (up to SDR104 mode at

208 MHz, 4–bit and 1-bit) host interfaces.

■ Backward compatible with SDIO v2.0 host interfaces.

■ Alternative host interface supports HSIC v1.0

■ PCIe mode complies with PCI Express base specification

revision 3.0 for ×1 lane and power management running at

Gen1 speeds.

■ Integrated ARMCR4™ processor with tightly coupled 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 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 and FM Key Features

■ Complies with Bluetooth Core Specification Version 4.1 with

provisions for supporting future specifications.

■ Bluetooth Class 1 or Class 2 transmitter operation.

■ 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 USB

or high–speed UART interface and PCM for audio data.

■ USB 2.0 full–speed (12 Mbps) supported for Bluetooth.

■ The FM unit supports HCI for communication.

■ Low power consumption improves battery life of handheld

devices.

■ FM receiver: 65 MHz to 108 MHz FM bands; supports the

European radio data systems (RDS) and the North American

radio broadcast data system (RBDS) standards.

■ Supports multiple simultaneous Advanced Audio Distribution

Profiles (A2DP) for stereo sound.

■ Automatic frequency detection for standard crystal and TCXO

values.

■ Supports serial flash interfaces.

General Features

■ Supports battery range from 3.0V to 5.25V supplies with

internal switching regulator.

■ Programmable dynamic power management

■ 484 bytes of user-accessible OTP for storing board parameters

■ GPIOs: 11 in WLBGA, 16 in WLCSP

■ Package options:

❐ 192-ball WLBGA (4.87 mm × 7.67 mm, 0.4 mm pitch

❐ 395-bump WLCSP (4.87 mm × 7.67 mm, 0.2 mm pitch)

■ Security:

❐ WPA™ and WPA2™ (Personal) support for powerful encryp-

tion and authentication

❐ AES and TKIP in hardware for faster data encryption and

IEEE 802.11i compatibility

❐ Reference WLAN subsystem provides Cisco® Compatible

Extensions (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.
