ATWINC3400-MR210xA IEEE 802.11 b/g/n Network Controller with Integrated Bluetooth Low Energy Module 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.
