LDC2114EVM: LDC2114 EVM porting with external MCU

Part Number: LDC2114EVM
Other Parts Discussed in Thread: LDC2114

Hi TI:

I want use external MCU(3V3 level) to porting with LDC2114 on EVM

EVM will power by J1 USB connector

Could I directly connect J4 signal to external MCU?

Or I need remove U6 MSP430 IC?

Thank you~~

  • Hi BR,

    Yes, you can connect the external MCU to the J4 connector. 

    Please note that we have 4.7k pullup resistors on the MCU section of the board, so you might want to change this depending on how much pull-up resistors you have on your MCU. You should not open the EVM GUI if you are connecting an external MCU, otherwise, the MCU starts communication as soon as you open the GUI. 

    Depopulating the U6 is also an option for you.

    Regards

    Sharath.
