Introduction
The ATWINC3400-MR210xA is an IEEE 802.11 b/g/n RF/Baseband/Medium Access Control (MAC) network
controller with Bluetooth Low Energy module. The ATWINC3400-MR210xA modules are Bluetooth 5.0 certified.
This module is optimized for low power and high performance mobile applications. This module features small
form factor with integrated Power Amplifier (PA), Low-Noise Amplifier (LNA), Transmit/Receive (T/R) switch (for
Wi-Fi® and Bluetooth) and Power Management Unit (PMU). The ATWINC3400-MR210CA integrates a chip antenna
while the ATWINC3400-MR210UA adds a micro co-ax (u.FL) connector for connecting to an external antenna. The
ATWINC3400-MR210xA module requires a 32.768 kHz clock for sleep operation.
The ATWINC3400-MR210xA module utilizes highly optimized IEEE 802.11 Bluetooth coexistence protocols, and
provides Serial Peripheral Interface (SPI) to interface with the host controller.
