CYPD5137-40LQXI

Application Specific Microcontrollers Overview

The CYPD5137-40LQXI is a USB Type-C port controller from the EZ-PD CCG5 series, manufactured by Infineon Technologies. It integrates two complete Type-C transceivers with termination resistors and an ARM Cortex-M0 processor running at 48 MHz. The device supports USB Power Delivery 3.0 and includes an integrated high-voltage regulator. Operating within a supply voltage range of 2.75 V to 5.5 V, it functions between -40°C and +85°C. Packaged in a 40-QFN format, it provides a comprehensive control solution for dual-port applications.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix to confirm package type and reel/tray configuration. Confirm RoHS compliance status through official documentation before integration. Check current availability as production cycles may vary. Ensure ESD handling procedures are followed due to moisture sensitivity classification.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring dual USB Type-C ports with PD 3.0 support. The 40-QFN package suits space-constrained PCB layouts. Verify that the host system can interface with the I2C communication protocol used by the integrated Cortex-M0 core for firmware updates and control.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-PD CCG5 family of USB Type-C controllers. Originally developed by Cypress Semiconductor, the product line is now managed by Infineon Technologies following their acquisition. The CYPD5137 variant specifically denotes the single-package version containing two port controllers in a 40-pin QFN footprint.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes within the same family include other CCG5 variants such as the CYPD5125 or CYPD5135, depending on whether single or dual port functionality is required. Cross-family migration to newer generations like CCG6 or CCG7 requires schematic and firmware redesign.
