UPD301A/KYX

Controllers Overview

The UPD301A 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 checking, and BMC encoding/decoding. Analog components such as VCONN FETs with Rp/Rd switching and current/voltage sense circuitry are included to reduce bill of materials. The controller 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 firmware stack supporting USB Power Delivery 3.0 specifications without custom development
• Integrated analog discrete components including VCONN FETs and overcurrent/overvoltage detection circuitry
• Stand-alone operation with configuration via external pin straps for power profile selection
• Optional dual-port capability through SPI connection to an external UPD350 controller

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 the manufacturer's Product Identification System to confirm temperature grade and package variant. Ensure the selected part matches the required application environment, whether commercial or automotive. Confirm that the preprogrammed firmware aligns with the intended power delivery profiles before finalizing procurement.

Controllers Selection Notes

Select the UPD301A when a turn-key, stand-alone USB Type-C source solution is required without external MCU dependency. Use the PDP_SEL configuration straps to define the supported power delivery objects directly at hardware reset. Consider the two-port architecture if multiple charging ports are needed, utilizing the UPD350 as a secondary controller managed by the UPD301A via SPI.

Controllers Part Context

The UPD301A belongs to Microchip's family of USB Type-C Power Delivery controllers. It serves as a dedicated port controller for source applications, distinct from dual-role or sink-only solutions. The device complements other Microchip interface products by providing a complete hardware and firmware foundation for USB-C compliance in consumer, industrial, and automotive electronics.

Controllers Replacement Considerations

No direct public substitute part numbers are documented for this component. Designers should evaluate alternative USB PD controllers based on pin compatibility and firmware support requirements.
