MCHPUSB2514B-I/M2
Overview
The USB2514B-I/M2 is a low-power, full-featured USB 2.0 Hi-Speed hub controller offering four downstream ports. It integrates MultiTRAK technology for dedicated Transaction Translators per port and includes PHYBoost for signal integrity adjustment in challenging PCB environments.
Why Choose This Part
This controller features internal 1.2V regulators and integrated pull-up/pull-down resistors to reduce BOM count. It offers significant flexibility through PortMap and PortSwap features, allowing engineers to remap logical ports to physical pins for optimized PCB routing.
Applications
Key Specifications
Getting Started
Initial configuration can be performed via an external I2C EEPROM or SMBus slave interface to customize Vendor and Product IDs. For hardware design, ensure the 24MHz crystal is placed close to the XTAL pins and follow Microchip's high-speed differential pair routing guidelines for the upstream and downstream ports.
