TMS320F2800137: Power

Part Number: TMS320F2800137

I would like to inquire about the 1.2V digital logic power supply pin of the VDD (4,44,59pin) of F2800137. Is it an output or an input, and if power is needed, what is the voltage? Also, the serial port can drive the optocoupler isolation driver 485. Do you need to add a driver?

    Hi luoyongg,

    Thanks for your questions.

    Please see the Pin Attributes table of the data sheet for details on what the purpose, I/O details, and power requirements of each pin.

    Please see the IOH and IOL specifications of the Electrical Characteristics table for seeing if you can drive the optocoupler's required current level.

    Regards,

    Vince
