QCA9377
QCA9377 includes both
dual-band 1x1 802.11ac and
Bluetooth 4.2 features
QCA9377 combines advanced 1x1 dual-band
802.11ac MU-MIMO Wi-Fi + Bluetooth 4.2 in
a high performance, ultra low power, small
form factor System-on-Chip (SoC).
Designed to deliver superior integration of WLAN
and Bluetooth low energy technology in a single-chip
solution, the QCA9377 SoC oers both low power
dual-band (2.4 & 5GHz), 1-stream (1x1), 802.11ac
MU-MIMO and Bluetooth 4.2 technologies.
QCA9377 supports high-speed Wi-Fi connectivity
and enriched media experiences for virtually all
connected devices. It is optimized for energy
eiciency, which is critical to extending the battery
life of portable devices. The software stack oers
quality, stability and performance with an open
source option and the architecture allows for virtually
seamless evolution.
QCA9377 allows for superior rate-over-range
throughput and low-latency performance in
real-world operating conditions by incorporating
Bluetooth coexistence, a special periodic switching
of the antenna designed to enable both Wi-Fi and
Bluetooth to operate in the same module eectively
at the same time.
The two variants available for QCA9377 are
QCA9377-3, which supports a low-power SDIO 3.0
interface for WLAN and a UART/PCM interface for
Bluetooth and QCA9377-7, which supports a low-
power USB 2.0 interface for WLAN and a USB 1.1
interface for Bluetooth.
Qualcomm Wi-Fi Solutions and QCA9377 are products of Qualcomm Technologies, Inc.
Advanced 802.11ac combo SoC
Advanced 802.11ac features such as MU-MIMO, Host
wake-on-wireless and ARP (Address Resolution Protocol)
offloading enable the WLAN link to remain associated for
extended periods for additional power savings.
Supports dual-mode Bluetooth
version 4.2
QCA9377 supports Bluetooth for Class-1 and Class-2
transmissions without requiring an external power amplifier.
Advanced Bluetooth/WLAN
coexistence and concurrent RX
WLAN/Bluetooth coexistence allows for superior rate-
over-range throughput and low-latency performance in
real-world operating conditions.
Power saving techniques for
ultra low power consumption
Both WLAN and Bluetooth power management utilize
advanced power saving techniques such as:
- gating clocks to idle or inactive blocks
- voltage scaling
- fast start and settling circuits
- active duty cycles
- processor frequency scaling
