USB251xB/xBi
USB 2.0 Hi-Speed Hub Controller
General Description Features The Microchip USB251xB/xBi 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. USB251xB/xBi products are fully footprint compatible with USB251x/xi/xA/xAi products as direct
drop-in replacements Highlights High performance, low-power, small footprint hub
controller IC with 2, 3, or 4 downstream ports Fully compliant with the USB 2.0 Specification [1] Enhanced OEM configuration options available
through either a single serial I2C EEPROM, or
SMBus slave port MultiTRAKTM
-High-performance multiple transaction translator which provides one transaction translator per port PortMap
-Flexible port mapping and disable sequencing PortSwap
-Programmable USB differential-pair pin locations ease PCB design by aligning USB signal lines directly to connectors PHYBoost
-Programmable USB signal drive strength for
recovering signal integrity using 4-level driving strength resolution пѓЈ 2010 -2015 Microchip Technology Inc. вЂ” Cost savings include using the same PCB
components and application of USB-IF Compliance
by Similarity Full power management with individual or ganged
power control of each downstream port Fully integrated USB termination and pull-up/pulldown resistors Supports a single external 3.3 V supply source;
internal regulators provide 1.2 V internal core voltage Onboard 24 MHz crystal driver or external
24 MHz clock input Customizable vendor ID, product ID, and device
ID 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: …
