Controllers datasheet and documents for UPD301AT-I/KYX

UPD301AT-I/KYX

Controllers Overview

The UPD301AT-I/KYX is a stand-alone USB Type-C Power Delivery 3.0 controller designed for source-only applications. It integrates an embedded 32-bit ARM Cortex-M0+ processor running preprogrammed PD firmware, eliminating the need for custom code development. The device supports standard power profiles of 15W, 27W, 45W, and 60W via configurable pin straps. It features an integrated USB PD MAC handling baseband communication, CRC generation, and BMC encoding. The component includes analog discrete components such as VCONN FETs with Rp/Rd switching and programmable current/voltage sense circuitry. It operates in commercial (0°C to +70°C) and industrial/automotive (-40°C to +85°C) temperature ranges within a 40-VQFN package.

Controllers Feature Summary

Preprogrammed USB Power Delivery 3.0 firmware stack supporting standard power profiles without custom development
Integrated analog front-end including VCONN FETs and over-current/over-voltage detection circuitry
Stand-alone operation capability with configuration defined by external pin straps
Optional dual-port expansion support via SPI connection to external UPD350 controllers

Controllers Applications

Point-of-Sale Terminals
Charging Lockers
IoT Products and Sensors
Smart Speakers and Monitors
Automotive Rear Seat Charging Ports

Controllers Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm temperature grade and packaging details. Ensure compatibility with system voltage requirements and interface configurations before procurement. Cross-reference the datasheet revision history for any operational updates or errata that may affect implementation.

Controllers Selection Notes

Select this component for applications requiring a turn-key USB Type-C source solution with minimal firmware overhead. Verify that the required power delivery profiles align with the available pin strap configurations. Consider the optional UPD350 add-on if dual-port dynamic power allocation is necessary for the design.

Controllers Part Context

The UPD301A series serves as a dedicated port controller for USB Type-C Power Delivery applications. It simplifies design by integrating the protocol stack and essential analog components into a single small form-factor chip. This approach reduces bill of materials and accelerates time-to-market for consumer, industrial, and automotive charging solutions.
