Introduction

The ATWILC3000A is a single chip IEEE 802.11 b/g/n RF/Baseband/Medium Access Control (MAC) link controller with Bluetooth 5.0, optimized for low-power mobile applications. This chip supports single stream 1x1 IEEE 802.11n mode, providing up to 72 Mbps PHY rate. The ATWILC3000A features fully integrated Power Amplifier (PA), Low Noise Amplifier (LNA), Transmit/Receive (T/R) switch and power management. The ATWILC3000A offers very low power consumption while simultaneously providing high performance and minimal bill of materials.

The ATWILC3000A utilizes highly optimized IEEE 802.11 Bluetooth coexistence protocols, and provides Serial Peripheral Interface (SPI) and Secure Digital Input Output (SDIO) to interface with the host controller. The only external clock sources required for the ATWILC3000A are a high-speed 26 MHz crystal oscillator and a 32.768 kHz clock for Sleep operation. The ATWILC3000A is available in the QFN package.
