5 Device Comparison

Table 5-1 shows a comparison between devices options, and highlights the key differences.

Note: Availability of features listed in this table are a function of shared IO pins, where IO signals associated with many of the features are multiplexed to a limited number of pins. The SysConfig-PinMux tool should be used to assign signal functions to pins. This will provide a better understanding of limitations associated with pin multiplexing.
Note: To understand what device features are currently supported by TI Software Development Kits (SDKs), see the AM243x SW Build Sheet.
