CYW4339
Features
IEEE 802.11x Key Features
™
■
■
IEEE 802.11ac compliant.
■
Integrated ARMCR4 processor with tightly coupled
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 768 KB SRAM and
640 KB ROM.
Single-stream spatial multiplexing up to 433.3 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.
™
■
OneDriver software architecture for easy migration
from existing embedded WLAN and Bluetooth
devices as well as future devices.
Tx and Rx low-density parity check (LDPC) support
for improved range and power efficiency.
■
■
■
Supports Rx space-time block coding (STBC)
Supports IEEE 802.11ac/n beamforming.
Bluetooth Key Features
■
Complies with Bluetooth Core Specification Version
4.1 with provisions for supporting future specifica-
tions.
On-chip power amplifiers and low-noise amplifiers for
both bands.
■
■
Support for optional front-end modules (FEM) with
external PAs and LNAs
■
■
Bluetooth Class 1 or Class 2 transmitter operation.
Supports extended synchronous connections (eSCO),
for enhanced voice quality by allowing for retransmis-
sion of dropped packets.
Shared Bluetooth and WLAN receive signal path elim-
inates the need for an external power splitter while
maintaining excellent sensitivity for both Bluetooth
and WLAN.
■
■
Adaptive frequency hopping (AFH) for reducing radio
frequency interference.
■
■
Internal fractional nPLL allows support for a wide
range of reference clock frequencies
Interface support, host controller interface (HCI) using
a USB or high-speed UART interface and PCM for
audio data.
Supports IEEE 802.15.2 external coexistence inter-
face to optimize bandwidth utilization with other co-
located wireless technologies such as LTE, GPS, or
WiMAX
■
■
■
■
■
USB 2.0 full-speed (12 Mbps) supported (FCFBGA
and WLCSP packages).
Low power consumption improves battery life of hand-
held devices.
■
Supports standard SDIO v3.0 (including DDR50 mode
at 50 MHz and SDR104 mode at 208 MHz, 4-bit and
1-bit) host interfaces.
Supports multiple simultaneous Advanced Audio Dis-
tribution Profiles (A2DP) for stereo sound.
■
■
Backward compatible with SDIO v2.0 host interfaces.
Automatic frequency detection for standard crystal
and TCXO values.
PCIe mode (FCBGA package only) complies with PCI
Express base specification revision 3.0 compliant
Gen1 interface for ×1 lane and power management
base specification.
Supports serial flash interfaces.
