UPD350AT/Q8X

Controllers Overview

The UPD350AT/Q8X is a highly integrated USB Type-C Power Delivery 3.0 port controller in a 28-QFN package. It supports I2C/SPI interfaces and operates at +1.8V to +3.3V with an industrial temperature range of -40°C to +85°C. The device features a PD MAC, cable detection logic, and integrated analog components including VCONN FETs and a power switch. It supports DRP, FRS, and Alternate Modes like DisplayPort.

Controllers Feature Summary

• Integrates USB Power Delivery 3.0 MAC for packet framing and CRC checking
• Supports Dual Role Port (DRP) and Fast Role Swap (FRS) with offload mode
• Includes integrated analog discrete components such as VCONN FETs and current/voltage sense circuitry
• Provides standalone UFP/DFP modes and companion interface via I2C or SPI

Controllers Applications

• Notebook Computers
• Docking Stations
• Multi-port Chargers

Controllers Procurement Notes

Verify the specific suffix 'T' against official Microchip documentation to confirm tape-and-reel packaging status, as standard listings may indicate tray packaging. Confirm end-of-life status and availability through authorized distributors. Ensure the industrial temperature grade (-40°C to +85°C) matches the application requirements before procurement.

Controllers Selection Notes

Select the UPD350AT/Q8X for designs requiring USB Type-C PD 3.0 compliance with integrated analog components. Choose this variant if an industrial temperature range is required. Verify compatibility with the host system's communication interface (I2C or SPI) and ensure the QFN-28 package fits the PCB footprint constraints.

Controllers Part Context

The UPD350 family includes variants with I2C (A/C) or SPI (B/D) interfaces and different temperature grades. The UPD350AT/Q8X specifically denotes the industrial grade version with the specified interface and packaging configuration within the UPD350 series designed for small form factor applications.

Controllers Replacement Considerations

Check for direct pin-compatible substitutes within the UPD350 family, such as UPD350A-I/Q8X or UPD350C-I/Q8X, depending on the required interface (I2C vs SPI). Verify that any replacement part maintains the same temperature rating and package type.
