3.3-V Operation  
description  
The TUSB2040A hub is a 3.3-V CMOS device  
that provides up to four downstream ports in  
compliance with the USB specification 1.0  
version. Pin 21 (EXTMEM) enables or disables  
the EEPROM interface. When EXTMEM is low,  
the TUSB2040A is functionally equivalent to the  
TUSB2040 hub and the product ID (PID)  
displayed during enumeration is General Purpose  
USB Hub. For this configuration, pins 9 and 10 are  
the BUSPWR and GANGED input pins,  
respectively.

If programmable vendor ID(VID) and product  
ID(PID) descriptors are desired, pin 21 must be  
high (EXTMEM = 1) and a SGS Thompson  
M93C46 or equivalent EEPROM must be  
connected to pins 9 and 10. For this configuration,  
the values for BUSPWR and GANGED are stored  
in the EEPROM and pins 9 and 10 become the  
EEPROM interface.
