Part Number: TM4C1290NCPDT
Other Parts Discussed in Thread: TM4C129ENCPDT

Our customer's original design used these two ICs. I preliminarily compared them. Now, tm4c129encpdti3r has some more functions, and the pins are compatible. Please confirm whether tm4c129encpdti3r can directly replace tm4c1290ncpdti3r without changing the original PCB and program?

    HI,

      See the difference between the two. TM4C129ENCPDT has Ethernet. Some Ethernet pins are dedicated pins. They can not be repurposed as GPIO pins as in TM4C1290NCPDT. TM4C129ENCPDT cannot be used as a replacement.
