USB2507-ADT

Controllers Overview

The USB2507-ADT is a fully compliant USB 2.0 compatible 7-port hub controller manufactured by Microchip Technology. It supports Low-Speed (1.5 Mbits/s), Full-Speed (12 Mbits/s), and High-Speed (480 Mbits/s) downstream devices, featuring a dedicated Transaction Translator for each port to ensure maximum throughput with mixed-speed peripherals. The device operates on a 1.8V core with 3.3V I/O that provides 5V input tolerance. Configuration is supported via an external serial I2C EEPROM, an SMBus slave interface, or hardware strapping options. It includes an internal 24MHz crystal driver circuit, an internal PLL for 480MHz sampling, and an integrated 1.8V linear voltage regulator.

Controllers Feature Summary

• Integrated USB 2.0 transceivers with dedicated transaction translators for each of the seven downstream ports.
• Flexible configuration methods including external I2C EEPROM, SMBus slave interface, and hardware strapping pins.
• Automatic detection and switching between bus-powered and self-powered operational modes.
• Internal power management features including short-circuit protection and integrated termination resistors.

Controllers Applications

• Desktop computer peripheral expansion systems
• Industrial control panels requiring multiple USB connections
• Embedded host systems needing high-speed data aggregation

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure the selected variant matches the required PCB footprint and thermal specifications for the target application environment.

Controllers Selection Notes

Select this component when a multi-port USB 2.0 solution with per-port transaction translation is required. Consider the 80-pin TQFP package constraints and verify compatibility with the system's clock source and power distribution architecture before finalizing the design.

Controllers Part Context

This part belongs to the Microchip USB2507 series of integrated USB hubs. It is designed as a drop-in replacement for legacy discrete hub solutions, consolidating the hub controller logic, transceivers, and bias circuits into a single semiconductor package to reduce board space and component count.

Controllers Replacement Considerations

Direct pin-compatible replacements within the same family include the USB2507B-I/PT. Verify functional equivalence regarding configuration interfaces and power management capabilities before substituting.
