USB2504A-JT

Controllers Overview

The USB2504A-JT is a fully compliant USB 2.0 compatible 4-port hub integrated circuit manufactured by Microchip Technology. It supports High-Speed (480 Mbits/s), Full-Speed (12 Mbits/s), and Low-Speed (1.5 Mbits/s) downstream devices on all enabled ports. The device features four dedicated Transaction Translators for maximum throughput with mixed-speed peripherals. It operates with a 1.8V low-power core and 3.3V I/O with 5V input tolerance. Configuration is supported via an external I2C EEPROM, SMBus slave interface, or hardware strapping options using internal default settings.

Controllers Feature Summary

• Integrated USB 2.0 transceivers and complete specification compliance
• Four dedicated transaction translators for high-performance mixed-speed operation
• Flexible configuration through SMBus, I2C EEPROM, or hardware strapping
• Automatic detection of bus-powered versus self-powered operating modes

Controllers Applications

• USB host expansion in personal computers and workstations
• Peripheral connectivity hubs for consumer electronics
• Industrial control systems requiring multiple USB connections
• Embedded systems needing reliable USB data distribution

Controllers Procurement Notes

Verify the specific package variant and revision level against the latest Microchip datasheet DS000002250A before procurement. Ensure that the ordering suffix matches the required RoHS compliance and lead-free specifications. Confirm compatibility with the intended system power architecture and configuration method to avoid functional mismatches during integration.

Controllers Selection Notes

Select this component when a fully USB 2.0 compliant 4-port hub solution is required with flexible configuration options. Consider the availability of external memory or microcontroller interfaces for custom VID/PID assignment. Evaluate the need for individual versus ganged port power switching based on the target application's power management requirements.

Controllers Part Context

This device belongs to the USB2504/USB2504A family of integrated USB hubs. It serves as a direct successor to earlier hub controllers, offering improved performance through dedicated transaction translators per port. The component is designed to replace legacy discrete hub solutions, providing a compact and efficient alternative for modern USB infrastructure designs.

Controllers Replacement Considerations

Public confirmed substitute part numbers include the USB2504B series for enhanced feature sets. Verify pin compatibility and electrical characteristics when substituting with other Microchip hub controllers. Cross-reference with older models like the USB20H04 only if backward compatibility is explicitly required.
