CYPD4225-40LQXIT

Application Specific Microcontrollers Overview

The CYPD4225-40LQXIT is a dual USB Type-C port controller from the EZ-PD CCG4 series, manufactured by Infineon Technologies (formerly Cypress Semiconductor). It integrates a 32-bit Arm Cortex-M0 processor running at 48 MHz with 128 KB flash and 8 KB SRAM. The device supports USB Power Delivery 3.0 and includes two integrated Type-C transceivers with BMC encoding/decoding. Operating voltage ranges from 2.7 V to 5.5 V, with I/O support down to 1.71 V. It features system-level ESD protection of ±8-kV contact discharge and ±15-kV air gap discharge on CC pins.

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Ensure storage conditions account for moisture sensitivity as indicated in the datasheet. Validate ordering part numbers against current Infineon portfolios to ensure continuity.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring dual USB Type-C connectivity with PD 3.0 protocol handling. The 40-pin QFN package suits applications needing extensive GPIOs and serial interfaces. Consider power consumption requirements, noting deep sleep currents of 2.5 µA. Ensure firmware development tools like the EZ-PD Configuration Utility are available for programming.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-PD CCG4 family of USB Type-C controllers. Originally developed by Cypress Semiconductor, it is now part of the Infineon Technologies portfolio. The CYPD4225 variant specifically supports dual ports with full PD 3.0 features, distinguishing it from single-port or limited-feature variants within the same series.

Application Specific Microcontrollers Replacement Considerations

Check for updated part numbers within the CCG4 family if availability changes. Verify pin compatibility with existing designs when considering alternatives like CYPD4226 or CYPD4236. Ensure firmware migration strategies are in place if switching between closely related models.
