4 Device Comparison

Table 4-1 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 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), search for the AM64x Software Build Sheet located in the Downloads tab option provided

at Processor-SDK-AM64x.

Note

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