Product Overview

The APW8811 is an ultra-low power Bluetooth 4.2 SoC based on the 32-bit ARM®Cortex®-M0 processor, integrated with high-performance 2.4GHz RF transceiver and rich digital interfaces. With on-chip Balun, there is no need for off-chip impedance matching network and external crystal oscillator load capacitance, which minimize BOM cost and PCB area. A high-efficiency DC-DC step-down converter is integrated to realize ultra-low power consumption.
