IFXCYPD4126-40LQXIT
Overview
The CYPD4126-40LQXIT is a highly integrated USB Type-C and Power Delivery (PD) controller featuring an Arm Cortex-M0 processor and 128KB of Flash. It is designed to manage complex power negotiation and data path multiplexing for dual-role power or downstream-facing ports. With its programmable digital blocks and low-power architecture, it provides a flexible solution for modern USB-C docking and peripheral designs.
Why Choose This Part
The integration of an Arm Cortex-M0 core allows for custom firmware implementation of complex PD policies while maintaining low power consumption of 10mA in active dual-port mode. It simplifies PCB layouts by integrating clocks, oscillators, and system-level ESD protection on the critical CC pins.
