Description of Qualcomm®QCA9377 Wi-Fi/Bluetooth SoC 

High performance, low power single-stream 11ac MU-MIMO and Bluetooth® 4.2 in a single-chip solution.

Qualcomm QCA9377 is a product of Qualcomm Technologies, Inc. 


QCA9377 combines advanced 1x1 dual-band 802.11ac MU-MIMO Wi-Fi + Bluetooth 4.2 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 offers both low power dualband (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 and is optimized for energy efficiency, 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:

1.QCA9377-3 - supports a low-power SDIO 3.0 interface for WLAN and a UART/PCM interface for Bluetooth.

2.QCA9377-7 - supports a low-power USB 2.0 interface for WLAN and a USB 1.1 interface for Bluetooth.
