ATWINC3400-MR210CA
IEEE® 802.11 b/g/n Network Controller with Integrated
Bluetooth® Low Energy Module
Introduction
The ATWINC3400-MR210CA is an IEEE 802.11 b/g/n RF/Baseband/Medium Access Control (MAC)
network controller with Bluetooth Low Energy module. The ATWINC3400-MR210CA 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), Power Management Unit (PMU), and Chip
Antenna. The ATWINC3400-MR210CA module requires a 32.768 kHz clock for Sleep operation.
The ATWINC3400-MR210CA module utilizes highly optimized IEEE 802.11 Bluetooth coexistence
protocols, and provides Serial Peripheral Interface (SPI) to interface with the host controller.
