ISP1520  
Hi-Speed Universal Serial Bus hub controller  
Rev. 04 — 28 April 2006  
Product data sheet  
1. General description  
The ISP1520 is a stand-alone Universal Serial Bus (USB) hub controller IC that complies  
with Universal Serial Bus Specification Rev. 2.0. It supports data transfer at high-speed  
(480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s).  
The upstream facing port can be connected to a Hi-Speed USB host or hub, or to an  
Original USB host or hub. If the upstream facing port is connected to a Hi-Speed USB  
host or hub, then the ISP1520 will operate as a Hi-Speed USB hub. That is, it will support  
high-speed, full-speed and low-speed devices connected to its downstream facing ports. If  
the upstream facing port is connected to an Original USB host or hub, then the ISP1520  
will operate as an Original USB hub. That is, high-speed devices that are connected to its  
downstream facing ports will operate in full-speed mode instead.  
The ISP1520 is a full hardware USB hub controller. All Original USB devices connected to  
the downstream facing ports are handled using a single Transaction Translator (TT), when  
operating in a cross-version environment. This allows the whole 480 Mbit/s upstream  
bandwidth to be shared by all the Original USB devices on its downstream facing ports.  
The ISP1520 has four downstream facing ports. If not used, ports 3 and 4 can be  
disabled. The vendor ID, product ID and string descriptors on the hub are supplied by the  
internal ROM; they can also be supplied by an external I2C-bus EEPROM or a  
microcontroller.  
The ISP1520 is suitable for self-powered hub designs.  
An analog overcurrent detection circuitry is built into the ISP1520, which can also accept  
digital overcurrent signals from external circuits; for example, Micrel MOSFET switch  
MIC2026. The circuitry can be configured to trip on a global or an individual overcurrent  
condition.  
Each port comes with two status indicator LEDs.  
Target applications of the ISP1520 are monitor hubs, docking stations for notebooks,  
internal USB hub for motherboards, hub for extending Intel Easy PCs, hub boxes, and so  
on.
