What is the GPIO current capability of the AM243

According to the AM243x datasheet, the maximum current that can be sourced or sunk by a single GPIO pin is typically:

4 mA for low-drive strength

8 mA for medium-drive strength

12 mA for high-drive strength

The AM243x datasheet only defines a single data point for current source/sink capability to achieve a specific output voltage (VOL or VOH) in the respective Electrical Characteristics section of the datasheet. The system designer will need to use the device IBIS model to determine the output voltage for any load other than the values defined in the IOL and IOH parameters.

Note: We only expect our digital output buffers to source CMOS inputs which have a minimum amount of leakage current when driving a steady-state logic level. We do not expect our digital outputs to drive any significant steady-state current.

See the table note associated with the IOL and IOH parameters.
