Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape/reel specifications. Ensure compatibility with required firmware update interfaces, such as the CC line programming method supported by this model. Confirm industrial temperature range requirements align with the -40 °C to +105 °C operating specification.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring a single USB Type-C port with PD 3.0 compliance. The integrated VCONN FETs and gate drivers reduce external component count. Verify that the host system can utilize the CC line for firmware updates if field upgrades are necessary. Ensure the power supply architecture supports the 2.7 V to 21.5 V input range.

Application Specific Microcontrollers Part Context

The CYPD3135-40LQXQ belongs to the EZ-PD CCG3 family of USB Type-C controllers. This series utilizes Cypress’s proprietary M0S8 technology and is now part of the Infineon Technologies portfolio. The device is housed in a 40-pin QFN package, suitable for space-constrained portable and desktop electronics.

Application Specific Microcontrollers Replacement Considerations

Check for updated revisions within the CCG3 family or newer generations like CCG4/CCG6 for enhanced features. Verify pinout compatibility if substituting with other CCG3 variants, noting differences in pre-programmed firmware and supported update interfaces.

Application Specific Microcontrollers FAQ
