1. Description

The Microchip USB2514B-AEZC-TR hub is a family of lowpower, configurable, MTT (multi transaction translator) hub controller IC products for embedded USB solutions. The x in the part number indicates the number of downstream ports available, while the B indicates battery charging support. The Microchip hub supports lowspeed, full-speed, and hi-speed (if operating as a hispeed hub) downstream devices on all of the enabled downstream ports

2. Features

    1. USB2514B-AEZC-TR products are fully footprint compatible with USB251x/xi/xA/xAi products as direct drop-in replacements

        — Cost savings include using the same PCB components and application of USB-IF Compliance by Similarity

    2. Full power management with individual or ganged power control of each downstream port

    3. Fully integrated USB termination and pull-up/pulldown resistors

    4. Supports a single external 3.3 V supply source; internal regulators provide 1.2 V internal core voltage

    5. Onboard 24 MHz crystal driver or external 24 MHz clock input

    6. Customizable vendor ID, product ID, and device ID

    7. 4 kilovolts of HBM JESD22-A114F ESD protection (powered and unpowered)

    8. Supports self- or bus-powered operation

    9. Supports the USB Battery Charging specification Rev. 1.1 for Charging Downstream Ports (CDP)

  10. The USB251xB/xBi offers the following packages:

       - 36-pin SQFN (6x6 mm) (Preferred)

       - 36-pin QFN (6x6 mm) (Legacy)

  11. USB251xBi products support the industrial temperature range of -40ºC to +85ºC

  12. USB251xB products support the extended commercial temperature range of 0ºC to +85ºC

3. Applications
