USB2514Bi-AEZG Description

The USB2514B is widely considered one of the most adaptable and dependable ICs currently available. It’s a controller for USB 2.0 hubs, so you can add multiple ports to a single device without effort. An in-depth look at the USB2514Bi-AEZG, including its features, specs, and potential uses, is provided here. This guide is written for engineers, designers, and enthusiasts to help you make well-informed decisions about using this IC in your next project.

General Description

Microchip’s USB251xB/xBi hub family of low-power, programmable MTT (multi-transaction translator) hub controller IC chips are ideal for embedded USB applications. A component with a B in its part number indicates that it can be used to charge batteries, and an x-valued component has a corresponding number of usable downstream ports. The Microchip hub’s enabled downstream ports can connect to devices moving at low speeds, full speeds, or even high speeds if the hub is set to act as a high-speed hub.

USB2514Bi-AEZG Features

  • Complete power management, with independent or grouped controls for all downstream ports.
  • A USB cable’s endpoint and pull-up/pull-down resistors are combined into a single, streamlined design.
  • Features a 1.2 V internal core voltage provided by built-in regulators and support for a single 3.3 V external power source.

Key Features

The USB2514Bi-AEZG is an IC with multiple functions designed to be a USB 2.0 hub controller. These are some of its distinguishing features:

● Compatible with USB 2.0:

Compatibility with the USB 2.0 standard was a primary design goal when developing the USB2514Bi-AEZG. It is compatible with both slow and fast USB signalling and can carry data at speeds of up to 480 Mbps.

● Multiple Downstream Ports:

The IC’s four downstream ports, each with its own data line, provide you with a wide range of options for how to link it to other devices. Because of this, multiple USB devices can be linked to a single PC. It is possible to connect and disconnect devices from the host computer without first powering down the machine because of the ports’ support for “hot swapping.”

● On-Chip Voltage Regulator:

The USB2514Bi-AEZG can operate from a single supply voltage of 4.4V to 5.5V thanks to its on-chip voltage regulator. No extra external voltage regulators are required for the device.

● Configurable Serial Interface Engine (SIE) and Transaction Translators (TTs):

The IC has an adaptable Serial Interface Engine (SIE) and supports several Transaction Translators (TTs). In this way, the IC can be customized by the user to serve a certain purpose better.

● Protection Features:

The USB2514Bi-AEZG has safeguards to protect it from electrical surges and other potentially harmful conditions, including protections against electrostatic discharge (ESD), overcurrent, and overvoltage. These fail-safes are intrinsic to the product and guarantee its security.

● Power-Saving Mode:

When engaged, the IC has a power-saving mode that reduces power consumption during inactive times. As a result, stationary system maintenance costs go down and the battery life of portable devices increases.

The USB2514Bi-AEZG has these features, making it a reliable and versatile alternative for integrating USB connectivity into a wide range of items, such as computer accessories, consumer electronics, and even industrial machinery.

USB2514Bi-AEZG Applications

  • Display devices based on liquid crystal technology
  • Multi-purpose USB accessories
  • computer motherboards
  • Electronics such as printers, scanners, and set-top boxes are included.
  • Storage space for discs in a computer
  • Modular, Transportable Network Nodes
  • Connection of portable computers to docks
  • Computing devices with circuitry built-in

Detailed Description

The USB2514Bi-AEZG IC, a USB 2.0 hub controller, is highly adaptable and dependable hardware.
