PRELIMINARY DATA SHEET  
MOS INTEGRATED CIRCUIT  
µ
PD72012  
HUB CONTROLLER FOR UNIVERSAL SERIAL BUS  
The µPD72012 is a dedicated LSI for a HUB connected to a universal serial bus (USB) system.  
It is an upgrade of NEC’s µPD72011. It conforms to Ver. 1.1 of the latest USB specifications.  
By putting descriptors in ROMization, information such as a user’s vendor ID can be implemented in the chip.  
FEATURES  
{ Conforms to Chapter 11 (HUB Specifications) of USB Specification 1.1 which is latest specifications.  
{ Descriptors in ROMization  
•
The user can customize the vendor ID and product ID.  
{ Supports 5 kinds of string descriptors (for User ROM code product only)  
{ On-chip sequencer  
•
There is an on-chip descriptor and request response sequencer. External initial setup and control is not needed  
and HUB functions can be realized using only the µPD72012.  
{ Downstream ports  
•
Four or five ports can be selected using a pin function.  
{ Power modes  
•
Bus power or self-power can be selected using a pin function (an external power control circuit is required).  
{ Corresponds to standard descriptor products  
•
Two kinds of standard ROM code products are provided. Standard and HUB class descriptors are on-chip in  
the µPD72012.  
ROM code: 003 (individual overcurrent monitoring type Generic HUB)  
ROM code: 004 (collective overcurrent monitoring type Generic HUB)  
{ Supports two kinds of clock input  
48-MHz oscillator input or a 4-MHz crystal resonator can be supported  
{ Power control  
Port power control and overcurrent detection functions are on-chip. Individual port control or collective control  
can be selected for these.
