USB4640-HZH-03-TR

Specialized Overview

The USB4640-HZH-03-TR is a high-speed USB interface integrated circuit manufactured by Microchip Technology. It functions as an HSIC to USB 2.0 hub controller, facilitating data transfer between High-Speed Inter-Chip (HSIC) hosts and standard USB peripherals. The device supports the USB 2.0 specification with a maximum data rate of 480 Mbps. It operates on a single power supply ranging from 1.1 V to 3.6 V, with a typical operating current of 58 mA. The component is housed in a 48-pin VQFN package measuring 7.15 x 7.15 mm with a height of 0.95 mm. It is designed for industrial temperature ranges, functioning between 0°C and +70°C.

Specialized Feature Summary

• Integrates HSIC 1.0 upstream connectivity with dual downstream USB 2.0 ports for combined hub and media controller applications.
• Supports ultra-fast interface standards enabling efficient communication between HSIC-enabled hosts and flash media formats.
• Includes built-in ESD protection mechanisms to safeguard internal circuitry during operation.

Specialized Applications

• Flash media card readers and writers
• Desktop and mobile personal computers
• Consumer audio/video equipment and flat panel displays
