Controllers Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm the specific -I/Q8X suffix matches design requirements. Check current availability status as this part may be discontinued. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification.

Controllers Selection Notes

Select the UPD350A variant specifically for designs requiring an I2C interface for host communication. Verify that the industrial temperature range (-40°C to +85°C) meets environmental specifications. Ensure the external MCU supports the required I2C protocol for configuration and control register access.

Controllers Part Context

This component belongs to the UPD350 family of USB Type-C controllers. It serves as a companion device to Microchip USB hubs or SoCs. The 'A' designation indicates the inclusion of an I2C interface, distinguishing it from SPI-based variants within the same product line.

Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Microchip technical support for end-of-life alternatives or next-generation replacements compatible with USB PD 3.0 standards.
