Revision History
FEATURES
FEATURES
Integrated ARMCR4 processor with tightly
IEEE 802.11X Key Features
•
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 768 KB
ROM.
•
•
IEEE 802.11ac 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.
Bluetooth Key Features
•
Provisioned for low energy angle-of-arrival
applications
•
•
•
Supports IEEE 802.11ac/n beamforming.
Supports real simultaneous dual-band (RSDB).
•
Complies with Bluetooth Core Specification
Version 4.1 with provisions for supporting future
specifications.
On-chip power amplifiers and low-noise
amplifiers for both bands. Also support for
external LNAs.
•
•
Bluetooth Class 1 or Class 2 transmitter
operation.
•
Supports three antennas with one dedicated to
Bluetooth and two to WLAN. Also, shared
Bluetooth and WLAN receive signal path
eliminates the need for an external power splitter
while maintaining excellent sensitivity for both
Bluetooth and WLAN.
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.
•
Supports multipoint external coexistence
interface to optimize bandwidth utilization with
other co-located wireless technologies such as
LTE and GPS.
Interface support, host controller interface (HCI)
using a USB or high-speed UART interface and
PCM for audio data.
•
•
•
Supports multiple simultaneous Advanced Audio
Distribution Profiles (A2DP) for stereo sound.
•
•
•
Supports standard SDIO v3.0 (up to SDR104
mode at 208 MHz, 4-bit and 1-bit) host interfaces.
Automatic frequency detection for standard
crystal and TCXO values.
Backward compatible with SDIO v2.0 host
interfaces.
Supports serial flash interfaces.
PCIe mode complies with PCI Express base
specification revision 3.0 for ×1 lane and power
management running at Gen1 speeds.
General Features
•
Supports battery range from 3.0V to 4.8V supplies
with internal switching regulator.
•
Security:
•
•
Programmable dynamic power management
– WPA, WAPI STA, and WPA2 (Personal)
support for powerful encryption and
authentication
Supports 1410 bytes of user-accessible OTP, of
which 256 bytes are allocated for BT and
1154 bytes are allocated for WLAN for storing
board parameters.
– AES and TKIP in hardware for faster data
encryption and IEEE 802.11i compatibility
•
•
GPIOs: 20
– Reference WLAN subsystem provides Cisco
Compatible Extensions (CCX, CCX 2.0, CCX
3.0, CCX 4.0)
194-ball WLBGA package
(4.97 mm × 7.44 mm, 0.4 mm pitch)
– Reference WLAN subsystem provides Wi-Fi
Protected Setup (WPS)
•
Worldwide regulatory support: Global products
supported with worldwide homologated design.
