5 Device Comparison

Table 5-1 shows a comparison between devices, highlighting the 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.
