down resistors

• Supports a single external 3.3 V supply source;

internal regulators provide 1.2 V internal core volt-

age

• Onboard 24 MHz crystal driver or external

24 MHz clock input

• Customizable vendor ID, product ID, and device

• 4 kilovolts of HBM JESD22-A114F ESD protection

(powered and unpowered)

• Supports self- or bus-powered operation

• Supports the USB Battery Charging specification

Rev. 1.1 for Charging Downstream Ports (CDP)

• The USB251xB/xBi offers the following packages:

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

- 36-pin QFN (6x6 mm) (Legacy)

• USB251xBi products support the industrial tem-

perature range of -40ºC to +85ºC

• USB251xB products support the extended com-

mercial temperature range of 0ºC to +85ºC

1.0

INTRODUCTION

The Microchip USB251xB/xBi hub family is a group of low-power, configurable, MTT (multi transaction translator) hub

controller ICs. The hub provides downstream ports for embedded USB solutions and is fully compliant with the

USB 2.0

Specification

[1]. Each of the hub controllers can attach to an upstream port as a full-speed or full-/hi-speed hub. The

hub can support low-speed, full-speed, and hi-speed downstream devices when operating as a hi-speed hub.

All required resistors on the USB ports are integrated into the hub. This includes all series termination resistors and all

required pull-down and pull-up resistors on D+ and D- pins. The over-current sense inputs for the downstream facing

ports have internal pull-up resistors.

The USB251xB/xBi hub family includes programmable features, such as:

•

MultiTRAK

Technology:

implements a dedicated Transaction Translator (TT) for each port. Dedicated TTs help

maintain consistent full-speed data throughput regardless of the number of active downstream connections.

•

PortMap:

provides flexible port mapping and disable sequences. The downstream ports of a USB251xB/xBi hub

can be reordered or disabled in any sequence to support multiple platform designs with minimum effort. For any

port that is disabled, the USB251xB/xBi hub controller automatically reorders the remaining ports to match the

USB host controller’s port numbering scheme.

•

PortSwap:

allows direct alignment of USB signals (D+/D-) to connectors to avoid uneven trace length or crossing

of the USB differential signals on the PCB.

•

PHYBoost:

enables 4 programmable levels of USB signal drive strength in downstream port transceivers. PHY-

Boost will also attempt to restore USB signal integrity.

1.1

Configurable Features

The USB251xB/xBi hub controller provides a default configuration that may be sufficient for most applications. Strapping

option pins (see

Section 3.3.1 on page 14)

provide additional features to enhance the default configuration. When the

hub is initialized in the default configuration, the following features may be configured using the strapping options:

•

Downstream non-removable ports, where the hub will automatically report as a compound device

Downstream disabled ports

Enabling of battery charging option on individual ports

The USB251xB/xBi hub controllers can alternatively be configured by an external I

C EEPROM or a microcontrol-

ler as an SMBus slave device. When the hub is configured by an I

C EEPROM or over SMBus, the following con-

figurable features are provided:

Support for compound devices on a port-by-port basis

Selectable over-current sensing and port power control on an individual or ganged basis to match the circuit board

component selection

Customizable vendor ID, product ID, and device ID

Configurable USB signal drive strength

Configurable USB differential pair pin location

Configurable delay time for filtering the over-current sense inputs

Configurable downstream port power-on time reported to the host

Indication of the maximum current that the hub consumes from the USB upstream port

Indication of the maximum current required for the hub controller

Custom string descriptors (up to 31 characters):

- Product

- Manufacturer

- Serial number

Battery charging USB251xB/xBi products are fully footprint compatible with USB251x/xi/xA/xAi products:

- Pin-compatible

- Direct drop-in replacement

- Use the same PCB components

- USB-IF Compliance by Similarity for ease of use and a complete cost reduction solution

- Product IDs, device IDs, and other register defaults may differ. See

Section 5.1 on page 19

for details.
