Datasheet  
3.1  
Pin Descriptions  
This section provides a detailed description of each pin. The signals are arranged in functional groups  
according to their associated interface.  
The “_N” symbol in the signal name indicates that the active, or asserted, state occurs when the signal  
is at a low voltage level. For example, RESET_N indicates that the reset signal is active low. When  
“_N” is not present after the signal name, the signal is asserted when at the high voltage level.  
The terms assertion and negation are used exclusively. This is done to avoid confusion when working  
with a mixture of “active low” and “active high” signals. The term assert, or assertion, indicates that a  
signal is active, independent of whether that level is represented by a high or low voltage. The term  
negate, or negation, indicates that a signal is inactive.  
Note: The buffer type for each signal is indicated in the BUFFER TYPE column of Table 3.1. A  
description of the buffer types is provided in Section 3.3.  
Note: Compatibility with the SMSC UCS100x family of USB port power controllers requires the  
UCS100x be connected on Port 1 of the USB4604. Additionally, both PRTPWR1 and OCS1_N  
must be pulled high at Power-On Reset (POR).
