CYW4343X
Features
IEEE 802.11x Key Features
■
Single-band 2.4 GHz IEEE 802.11b/g/n.
■
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.
■
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.
■
OneDriver™ software architecture for easy migration
from existing embedded WLAN and Bluetooth devices
as well as to future devices.
■
■
Supports standard SDIO v2.0 and gSPI host inter-
faces.
Supports Space-Time Block Coding (STBC) in the
receiver.
Bluetooth and FM Key Features
■
Complies with Bluetooth Core Specification Version
4.1 with provisions for supporting future specifications.
■
■
FM receiver unit supports HCI for communication.
Low-power consumption improves battery life of hand-
held devices.
■
■
Bluetooth Class 1 or Class 2 transmitter operation.
Supports extended Synchronous Connections
(eSCO), for enhanced voice quality by allowing for
retransmission of dropped packets.
■
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.
■
■
Adaptive Frequency Hopping (AFH) for reducing radio
frequency interference.
■
■
Supports multiple simultaneous Advanced Audio Dis-
tribution Profiles (A2DP) for stereo sound.
Interface support — Host Controller Interface (HCI)
using a high-speed UART interface and PCM for audio
data.Bluetooth and FM Key Features (Continued)
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.
