Overview

The CYPD4126-40LQXI is a member of the Infineon CCG4 family, a highly integrated dual-port USB Type-C and Power Delivery (PD) controller based on an Arm Cortex-M0 core. It provides a complete USB-C solution including integrated digital blocks and system-level ESD protection on Configuration Channel (CC) pins. Operating from 2.7V to 5.5V, this controller manages the complexities of PD negotiation and port management in a compact 40-UFQFN package.

Why Choose This Part

This controller features 128KB of Flash and 8KB of RAM, allowing for field-upgradable firmware to meet evolving USB PD standards. It reduces BOM complexity by integrating multiple interfaces including I2C, SPI, and UART alongside dedicated USB-PD hardware. The low-power Deep Sleep mode, consuming only 80 uA, makes it suitable for power-sensitive mobile applications.

Applications

Notebook and PC Power Delivery
Managing dual USB-C ports for charging and data transfer in portable computing devices.
USB-C Docking Stations
Handling power negotiation and peripheral interfacing for multi-port expansion hubs.
Industrial USB PD Controllers
Providing reliable Power Delivery and interface management in harsh environments with its -40 to 85 degree Celsius operating range.
Monitor and Display Hubs
Integrating USB-C power delivery and data management within high-resolution display systems.

Getting Started

Engineers can develop for the CYPD4126 using the PSoC Creator IDE or ModusToolbox, which provide comprehensive middleware for USB Power Delivery. Development can be accelerated using Infineon's CCG4 evaluation kits (such as the CY4541), and firmware can be programmed via the integrated SWD interface.
