USB2512B-AEZG USB Interface IC

For embedded USB solutions, the USB2512B-AEZG is a 2-port USB 2.0 high-speed low-power Hub Controller IC. Intel explicitly designs it. Applications with extremely low power consumption and a tiny footprint but do not want to sacrifice performance can benefit from the USB251xB family of solutions. It can accomplish this by utilizing Microchip’s ground-breaking MultiTRAKTM technology, an innovation that enables the best data throughput in the industry when operating in mixed-speed USB applications. This is a ground-breaking invention. The USB251xB family is an expansion solution for USB ports that can be used with devices that use the USB standard.

There are over 30 programmable features that are designed to assist system designers in simplifying PCB layout and optimizing bill-of-material cost. These features can be accessed through the system’s graphical user interface (GUI). Some examples of these features include PortSwap, PortMap, and PHYBoost, all of which are made by Microchip. These capabilities can be accessed using a graphical user interface (GUI). Each downstream port of the USB251xB hubs can be set up to support the USB battery charging 1.1 specifications and function as a charging downstream port if the appropriate option is selected (CDP). A mobile phone or other compatible portable electronic device can use a standard USB port to use a CDP’s universal battery charging capability.

All members of the USB251xB family are offered a compact size ideal for consumer and mobile applications. The standard 36-pin package that all 2/3/4 port hub controllers use has a footprint of only 6×6 millimeters, making it ideal for limited space designs while allowing for scalable port extension from two to four ports.

The USB251xB has a wide operating temperature range from 0 degrees to 85 degrees Celsius. The standards for -40 degrees to 85 degrees Celsius imposed on industrial environments are met by the USB251xBi. It is essential to note that new designs will focus on the “M2” product variants. The M2 goods are created using the most recent iteration of the production flow, which results in increased capacity and efficiency. No product versions of the USB251xB are getting close to reaching their end of life, and all versions have maintained their position as entirely produced release candidates.

Frequently Asked Questions

What is a USB 2.0 port?

Hi-speed USB, or USB 2.0, is another name for this version of the standard. It was first utilized in the year 2000. It is an updated version of the USB 1.1 standard, which offers enhanced features and increased transfer rates. It can deliver 480 megabits per second, which is the maximum transfer speed it is capable of. On the other hand, the actual speed is somewhere about 280 Mbps.

Are all USB 2.0 ports the same?

There are a lot of different standard connections that can be used for USB devices, but in general, they all perform the same purpose. The only real difference between them is how they look physically.
