The USB2514BI-AEZG-TR from Microchip Technology is a low-power, high-performance 4-port USB 2.0 Hi-Speed hub controller designed for embedded USB hub applications. It is fully compliant with the USB 2.0 specification and supports Hi-Speed, Full-Speed and Low-Speed downstream USB devices, with Hi-Speed data rates of up to 480Mbps.
The device incorporates Microchip’s MultiTRAK™ multiple-transaction-translator architecture, providing one transaction translator for each downstream port. This architecture improves performance when multiple Full-Speed or Low-Speed peripherals operate simultaneously through the hub. The USB2514B provides four downstream USB ports from a single upstream host connection.
Extensive OEM configuration is available through an external serial I²C EEPROM or SMBus slave interface. Configurable parameters include Vendor ID, Product ID and Device ID. Integrated PortMap, PortSwap and PHYBoost™ technologies provide flexible port mapping, programmable USB differential-pair pin locations and adjustable USB signal drive strength for improved PCB routing and signal integrity.
The USB2514BI supports individual or ganged downstream-port power control and can operate in either self-powered or bus-powered hub configurations. It also supports the USB Battery Charging Specification Revision 1.1 for Charging Downstream Ports and integrates USB termination and pull-up/pull-down resistors to reduce external component requirements.
The controller operates from a single 3.3V supply, with an official operating range of 3.0V to 3.6V, while internal regulators generate the required 1.2V core supply. It supports either an onboard 24MHz crystal or an external 24MHz clock source and provides up to 4kV HBM ESD protection.
For the specific USB2514BI-AEZG-TR ordering code, the “I” designation specifies the -40°C to +85°C industrial temperature range, while AEZG identifies the 36-pin QFN, 6×6mm package. The “-TR” suffix specifies tape-and-reel packaging with 3000 pieces per reel. Microchip currently lists the USB2514B family as In Production, although the AEZG 36-QFN package is designated as a legacy package, with the 36-pin SQFN recommended for new designs.
