MICROCHIP ATWILC3000-MR110UA

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, 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.
