Signal Descriptions
The AM335x device contains many peripheral interfaces. In order to reduce package size and lower
overall system cost while maintaining maximum functionality, many of the AM335x terminals can multiplex
up to eight signal functions. Although there are many combinations of pin multiplexing that are possible,
only a certain number of sets, called IO Sets, are valid due to timing limitations. These valid IO Sets were
carefully chosen to provide many possible application scenarios for the user.
Texas Instruments has developed a Windows-based application called Pin Mux Utility that helps a system
designer select the appropriate pin-multiplexing configuration for their AM335x-based product design. The
Pin Mux Utility provides a way to select valid IO Sets of specific peripheral interfaces to ensure the pin-
multiplexing configuration selected for a design only uses valid IO Sets supported by the AM335x device.
