Highlights
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 5
QCA9377 supports Bluetooth for Class-1 and Class-2
transmissions without requiring an external power
amplifier.
Advanced WLAN/Bluetooth
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 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
High performance, low power single-stream
11ac MU-MIMO and Bluetooth 5
in a single-
chip solution.

87-YB797-1 Rev C
QCA9377 combines advanced 1x1 dual-band
802.11ac MU-MIMO Wi-Fi + Bluetooth 5 in
a high performance, 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 oers both low power dual-
band (2.4 & 5GHz), 1-stream (1x1), 802.11ac
MU-MIMO and Bluetooth 5.0 technologies.
QCA9377 supports high-speed Wi-Fi
connectivity and enriched media experiences
for virtually all connected devices and
is optimized for energy eciency, which
is critical to extending the battery life of
portable devices.
With advanced WLAN/Bluetooth
coexistence algorithms, QCA9377 supports
superior rate-over-range throughput and
low-latency performance in real-world
operating conditions.
The QCA9377 SoC is available in two
variants:
QCA9377-3 - supports a low-power
SDIO 3.0 interface for WLAN and a
UART/PCM interface for Bluetooth.
QCA9377-7 - supports a low-power USB
2.0 interface for WLAN and a USB 1.1
interface for Bluetooth.
