Checking for live stock

The UPD350B-I/Q8X from Microchip Technology is a USB controller engineered for USB 3.0 applications demanding reliable link control and power management. It integrates the core USB interface functions needed to manage device connection, configuration, and communication. It is intended for embedded systems where board space is limited but stable USB performance is required, such as portable instruments, industrial devices, and consumer electronics.

Core Features and Benefits of Choosing the Microchip USB Controller, USB 3.0, 28-Pin QFN

Supports USB 3.0 link and power management functions.
28-pin QFN package allows compact PCB layout.
Provides interface control for device enumeration and communication.
Suitable for embedded systems with limited board space.
Supports stable USB link operation across typical embedded environments.

Engineered for Embedded USB System Integration

This controller is used in designs where the USB port must reliably manage connection negotiation and data link events. Its small footprint enables efficient routing on multi-layer PCBs, and its standardised pin configuration simplifies schematic placement and integration alongside host microcontrollers or processors.

Typical Application Scenarios

USB interface control in handheld or portable devices.
Embedded system communication ports requiring USB connectivity.
Industrial equipment and monitoring systems with PC or host interfaces.
Consumer electronics that integrate USB device functionality.
Designs that require USB link control without a complete USB subsystem on the main MCU.
