DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD72012  
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 complies with USB specification revision 1.1.  
By putting descriptors into ROM, information such as a user’s vendor ID can be implemented in the chip.  
FEATURES  
{ Compliant with Chapter 11 (HUB Specifications) of USB Specification 1.1.  
{ Descriptors into ROM  
• The user can customize the vendor ID and product ID by using Mask ROM option.  
{ Supports 5 kinds of string descriptors (for Mask 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.
