CYPD5125-40LQXIT

Application Specific Microcontrollers Overview

The CYPD5125-40LQXIT is a single-port USB Type-C controller from the EZ-PD™ CCG5 family, designed for compliance with USB Type-C and USB Power Delivery (PD) 3.0 standards. It integrates an ARM Cortex-M0 processor running at 48 MHz, 128 KB of flash memory, and 12 KB of SRAM. The device includes two integrated USB-PD Type-C ports, though this specific package utilizes one port. Key features include integrated VCONN FETs, high-voltage LDO supporting up to 21.5 V, and comprehensive protection mechanisms such as OVP, OCP, and ESD protection on CC, D±, and SBU pins.

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm that the ordering part number matches the required package and temperature grade. Check for any specific revision notes or obsolescence notices on the manufacturer's official website before finalizing procurement plans.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring a single USB Type-C port with PD 3.0 support. Ensure the application voltage range aligns with the 2.75 V to 21.5 V operational limits. Consider the 40-pin QFN package dimensions and thermal requirements. Verify that the host system can interface with the available SCB modules for I2C, SPI, or UART communication.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-PD™ CCG5 series, which also includes dual-port variants like the CYPD5225 in a 96-ball BGA package. The CYPD5125 is specifically packaged in a 40-pin QFN format suitable for space-constrained single-port applications. It represents a transition from Cypress Semiconductor products to the Infineon Technologies portfolio.

Application Specific Microcontrollers Replacement Considerations

For pin-to-pin compatible replacements, refer to the CCG5C datasheet. The document notes that certain variants are Not Recommended for New Designs (NRND); consult the latest product availability status and cross-reference with current Infineon recommendations for long-term supply assurance.
