CYPD4225-40LQXI

Application Specific Microcontrollers Overview

The CYPD4225-40LQXI is a dual USB Type-C port controller from the EZ-PD™ CCG4 family, designed for notebooks, power adapters, and docking stations. It integrates two complete Type-C transceivers with termination resistors (RP/RD) and VCONN FETs on a single chip. The device features a 32-bit Arm Cortex-M0 processor running at 48 MHz, equipped with 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 of 1.71 V to 5.5 V. The component is housed in a 40-pin QFN package.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature range. Confirm firmware compatibility requirements using the EZ-PD™ Configuration Utility before integration. Check for any end-of-life notices or alternative part recommendations directly from Infineon Technologies.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring dual USB Type-C connectivity with high-speed Power Delivery negotiation. Ensure the host system can accommodate the 40-pin QFN footprint. Verify that the application logic fits within the 128 KB Flash memory limit and utilizes the available GPIOs and communication blocks effectively.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-PD™ CCG4 series, which utilizes Infineon’s M0S8 technology. It serves as a comprehensive solution for dual-port USB Type-C applications, distinguishing itself from single-port controllers by integrating two full transceiver sets and associated control logic on one die.
