USB2502-HT

Controllers Overview

The USB2502-HT is a 2-port USB 2.0 hub controller compliant with the Universal Serial Bus Specification Revision 2.0. It supports High-Speed (480 Mbits/s), Full-Speed (12 Mbits/s), and Low-Speed (1.5 Mbits/s) downstream devices. The device features an integrated 1.8V core, 3.3V I/O with 5V tolerance, and internal transceivers. Configuration is supported via hardware strapping, SMBus slave interface, or external I2C EEPROM. It includes an internal PLL for 480MHz sampling and a 24MHz crystal driver circuit. Power management allows automatic detection of bus-power or self-power sources.

Controllers Feature Summary

• Integrated USB 2.0 compatible 2-port hub supporting high-speed, full-speed, and low-speed downstream connections
• Automatic power source detection enabling dynamic switching between bus-powered and self-powered modes
• Flexible configuration options through hardware strapping pins, SMBus slave interface, or external I2C EEPROM
• Internal 1.8V linear voltage regulator and 24MHz crystal driver circuit with integrated USB termination resistors

Controllers Applications

• USB host expansion in computing systems requiring additional peripheral connectivity
• Embedded industrial control panels needing robust USB connectivity with configurable port behavior
• Consumer electronics devices integrating multiple USB peripherals within compact form factors

Controllers Procurement Notes

Verify the specific suffix 'HT' against Microchip's official documentation to confirm temperature range and package availability. Ensure the selected package type matches the design requirements, as the device is available in 36-pin QFN and 48-pin TQFP configurations. Confirm RoHS compliance status for the specific orderable part number before procurement.

Controllers Selection Notes

Select this component when a dual-port USB 2.0 solution is required with flexible power management capabilities. Consider the internal default configuration if external memory or complex SMBus integration is not feasible. Evaluate the need for compound device support and non-removable port definitions during the design phase to utilize the hardware strapping options effectively.

Controllers Part Context

The USB2502 belongs to Microchip's family of USB 2.0 hub controllers designed for cost-effective and space-constrained applications. It provides a complete solution by integrating necessary PHY components and control logic into a single chip. The device simplifies system design by reducing the component count typically required for USB hub implementations.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not identified in the provided documentation. Verify compatibility with existing designs by comparing pinouts, electrical specifications, and configuration interfaces with alternative hub controllers from other manufacturers.
