CYPD4236-40LQXQ

Application Specific Microcontrollers Overview

The CYPD4236-40LQXQ is a dual-port USB Type-C controller from the EZ-PD™ CCG4 family, designed for notebooks, power adapters, and docking stations. It integrates two complete Type-C transceivers with integrated termination resistors (RP/RD) and VCONN FETs. The device features a 48-MHz Arm® Cortex®-M0 processor, 128 KB flash, and 8 KB SRAM. It supports USB Power Delivery 3.0, including fast role swap and extended data messaging. 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. System-level ESD protection on CC pins meets IEC61000-4-2 Level 4C standards.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'Q' against Infineon documentation to confirm tape-and-reel packaging requirements. Ensure compatibility with the EZ-PD™ Configuration Utility for firmware programming. Confirm that the 40-pin QFN package dimensions align with the target PCB layout constraints.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring dual USB-C ports with PD 3.0 compliance. The integrated digital blocks reduce external component count. Verify that the host system can support the required 2.7 V to 5.5 V operating range. Consider the availability of PSoC™ Creator or EZ-PD SDK tools for firmware development.

Application Specific Microcontrollers Part Context

The CYPD4236-40LQXQ belongs to the EZ-PD™ CCG4 family, which includes variants like CYPD4225 and CYPD4226. These controllers share the same core architecture but may differ in pinout configurations or specific peripheral mappings. The CCG4 series is positioned as a comprehensive solution for dual-port Type-C implementations in portable and desktop electronics.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes within the CCG4 family include CYPD4225-40LQXQ and CYPD4226-40LQXQ. Verify pin-to-pin compatibility and firmware configuration differences before substitution. Other generations like CCG5 or CCG6 offer different feature sets and may require schematic redesign.
