Overview

The USB2412-DZK is a high-speed USB 2.0 hub controller designed for applications requiring a small footprint and low power consumption. This two-port controller integrates USB termination, pull-up/pull-down resistors, and 1.2V internal regulators, reducing the need for external components. It supports both self-powered and bus-powered modes while providing 4kV ESD protection on all USB pins.

Why Choose This Part

The IC simplifies design by integrating the core voltage regulator and all necessary USB termination resistors. Its low operating current of 40mA and standby power of 475uA make it suitable for power-sensitive mobile applications, while the 28-QFN package with 0.5mm pitch facilitates dense routing.

Applications

Embedded USB Hubs
Adding downstream USB ports to industrial PCs or single-board computers where PCB space is limited.
Compound Devices
Integrating multiple USB functions behind a single physical connector in consumer electronics.
Docking Stations
Providing reliable high-speed connectivity for peripherals in mobile docking or port expansion products.
Non-Removable Port Integration
Permanently connecting internal modules like Wi-Fi or Bluetooth controllers to a host processor's USB interface.

Getting Started

Designers should provide a stable 3.3V supply and a 24 MHz crystal or external clock source. Configuration can be handled through hardware strapping pins or an external I2C EEPROM if custom Vendor ID/Product ID strings are required. Refer to the Microchip EVB-USB2412 evaluation board documentation for layout best practices regarding differential pair impedance.
