USB2504-JT

Controllers Overview

The Microchip USB2504-JT is a fully compliant USB 2.0 compatible 4-port hub controller designed for high-performance data transfer. It supports High-Speed (480 Mb/s), Full-Speed (12 Mb/s), and Low-Speed (1.5 Mb/s) downstream devices, featuring four dedicated Transaction Translators to maximize throughput with mixed-speed peripherals. The device operates on a 1.8V low-power core with 3.3V I/O tolerant to 5V inputs. It includes an internal 1.8V linear voltage regulator, an internal PLL for 480MHz sampling, and integrated USB termination resistors. Configuration is flexible via hardware strapping, an external serial I2C EEPROM, or an SMBus slave interface.

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and configuration options. Confirm that the component meets all relevant environmental compliance standards required for the intended deployment environment before finalizing procurement orders.

Controllers Selection Notes

Select this component when a robust USB 2.0 hub solution with multiple configuration methods is required. Consider the 64-pin LQFP package constraints and the need for external power distribution switches if port power switching is utilized. Ensure the design accommodates the 24MHz crystal or clock input requirements for proper operation.

Controllers Part Context

This part belongs to the Microchip USB2504/USB2504A series of integrated USB 2.0 compatible 4-port hubs. It serves as a direct replacement for legacy solutions like the USB20H04 while offering enhanced features such as dynamic power switching and flexible configuration options through various interfaces.

Controllers Replacement Considerations

The USB2504A is a backward-compatible version of the USB2504. Verify pin compatibility and functional equivalence if substituting between these variants in existing designs.
