IFXCYPD3125-40LQXI
Overview
The CYPD3125-40LQXI is a highly integrated USB Type-C port controller from the EZ-PD CCG3 family, featuring an ARM Cortex-M0 core and 128KB of flash memory. It simplifies USB-C hardware design by integrating VBUS gate drivers, high-voltage regulators, and termination resistors into a single 40-UFQFN package. This controller is designed to support the full range of USB Power Delivery (PD) specifications and includes hardware-based security features for device authentication.
Why Choose This Part
This part significantly reduces BoM cost and board space by integrating a 20V-tolerant regulator and dual gate drivers for VBUS control. Its hardware encryption engine and 128KB of dual-bank flash allow for secure, fail-safe firmware updates over the USB interface, ensuring long-term field reliability and compliance with evolving PD standards.
Applications
Key Specifications
Getting Started
Development is supported by the Infineon EZ-PD Configuration Utility and the ModusToolbox software suite. For hardware evaluation, engineers typically use the CY4531 EZ-PD CCG3 Evaluation Kit, which provides a complete platform for testing Power Delivery and Alternate Mode functionality. Firmware can be customized using the ARM Cortex-M0 toolchain to handle specific power profiles or unique hardware requirements.
