CYW4343X

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 shared between WLAN and Bluetooth.

■

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 inter-

faces.

■

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 pro-

cessor for standard WLAN functions. This allows for

further minimization of power consumption, while

maintaining the ability to field-upgrade with future fea-

tures. On-chip memory includes 512 KB SRAM and

640 KB ROM.

■

OneDriver™ software architecture for easy migration

from existing embedded WLAN and Bluetooth devices

as well as to 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 high-speed UART interface and PCM for audio

data.Bluetooth and FM Key Features (Continued)

■

FM receiver unit supports HCI for communication.

■

Low-power consumption improves battery life of hand-

held 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 Dis-

tribution Profiles (A2DP) for stereo sound.

■

Automatic frequency detection for standard crystal and

TCXO values.

General Features

■

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[4343W+43CS4343W1]74-ball 63-ball WLBGA

package (4.87 mm × 2.87 mm, 0.4 mm pitch).

■

153-bump WLCSP package (115 μm bump diameter,

180 μm bump 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 Com-

patible Extensions (CCX, CCX 2.0, CCX 3.0, CCX

4.0, CCX 5.0).

❐ Reference WLAN subsystem provides Wi–Fi Pro-

tected Setup (WPS).

■

Worldwide regulatory support: Global products sup-

ported with worldwide homologated design.

■

Multimode wireless charging support that complies

with the Alliance for Wireless Power (A4WP), the

Wireless Power Consortium (WPC), and the Power

Matters Alliance (PMA).
