CYPD4226-40LQXIT

Application Specific Microcontrollers Overview

The CYPD4226-40LQXIT is a dual-port USB Type-C controller from the EZ-PD™ CCG4 family, designed for notebooks, power adapters, and docking stations. It features a 48-MHz Arm® Cortex®-M0 processor with 128 KB Flash and 8 KB SRAM. The device integrates two complete Type-C transceivers with USB-PD 3.0 support, including BMC transceivers, integrated VCONN FETs, and dead battery termination. Operating voltage ranges from 2.7 V to 5.5 V, with an independent GPIO supply supporting 1.71 V to 5.5 V signaling. It supports fast role swap and extended data messaging within a 40-pin QFN package.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with the EZ-PD™ configuration utility for firmware programming. Check for any updates regarding the availability of software development kits or reference designs associated with the CCG4 family.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring dual USB Type-C ports with Power Delivery capabilities. The integrated transceivers and MCU reduce external component count. Verify that the required GPIO count and serial interface configurations fit within the available SCB and TCPWM resources. Consider the operating temperature range and voltage requirements for the target system design.

Application Specific Microcontrollers Part Context

The CYPD4226-40LQXIT belongs to the EZ-PD™ CCG4 family of dual-port USB Type-C controllers. This family utilizes Infineon’s M0S8 technology and is part of a broader portfolio including single-port controllers like the CCG6 and automotive-grade solutions like the CCG7D. The CCG4 series is specifically targeted at notebook, adapter, and dock applications.
