Introduction

The ATWILC3000-MR110xA module is an IEEE 802.11 b/g/n RF/Baseband/Medium Access Control (MAC) link controller and Bluetooth 5.0 compliant module⁽¹⁾, optimized for low power mobile applications. This module supports single stream 1x1 IEEE 802.11n mode providing up to 72 Mbps PHY rate. The ATWILC3000-MR110xA module features small form factor when integrating Power Amplifier (PA), Low Noise Amplifier (LNA), Transmit/Receive switch and Power Management. The ATWILC3000-MR110CA integrates a chip antenna while the ATWILC3000-MR110UA adds a micro co-ax (u.FL) connector for connecting to an external antenna. This module offers very low power consumption while simultaneously providing high performance. This module contains all circuitry required including a 26 MHz crystal, PMU circuitry and a chip antenna or a micro co-ax (u.FL) RF connector. The ATWILC3000-MR110xA module requires a 32.768 kHz clock for sleep operation.

The ATWILC3000-MR110xA module utilizes highly optimized IEEE 802.11 Bluetooth coexistence protocols and provides Serial Peripheral Interface (SPI) and Secure Digital Input Output (SDIO) for interfacing with the host controller.
