ATWILC3000A
Single Chip IEEE 802.11 b/g/n Link Controller with
®
Integrated Bluetooth 5.0
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.
