CYW4356/CG8674
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.
Bluetooth Key Features
■ Qualified for Bluetooth Core Specification 5.0:
❐ QDID: 115131
❐ Declaration ID: D038396
■ Supports Basic Rate (BR), Enhanced Data Rate (EDR) and
Bluetooth Low Energy (BLE)
■ 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.
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 param-
eters
■ 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)
■ 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.
■ PCIe mode complies with PCI Express base specification
revision 3.0 for ×1 lane and power management running at
Gen1 speeds.
■ Supports Active State Power Management (ASPM).
■ 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.
■ Supports A4WP wireless charging with the BCM59350.
■ 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.
■ 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.
■ Security:
❐ WPA and WPA2 (Personal) support for powerful encryption
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 Set-
up (WPS)
■ Worldwide regulatory support: Global products supported with
worldwide homologated design.
