4 Device Comparison

Table 4-1 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.

Note

Features availability may vary by package within an orderable part number.
