PRELIMINARY

CYW43340

Bluetooth Key Features

■ Complies with Bluetooth Core Specification Version 4.0 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 high-

speed UART interface and PCM for audio data

■ Low power consumption improves battery life of handheld

devices.

■ Supports multiple simultaneous Advanced Audio Distribution

Profiles (A2DP) for stereo sound.

■ Automatic frequency detection for standard crystal and TCXO

values

General Features

■ Supports battery voltage range from 2.9V to 4.8V supplies with

internal switching regulator.

■ Programmable dynamic power management

■ 3072-bit OTP for storing board parameters

■ Routable on low–cost 1x1 PCB stack–ups

■ 141-ball WLBGA package(5.67 mm × 4.47 mm, 0.4 mm pitch)

■ Security:

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

tion and authentication

❐ AES in WLAN 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 Set-

up (WPS)

■ Worldwide regulatory support: Global products supported with

worldwide homologated design
