MSP-TS430RGC64C: Is a diode connected to the JTAG circuit necessary?

Genius 5840 points
Part Number: MSP-TS430RGC64C


In the circuit diagram of the MSP-TS430RGC64C, several diodes are connected to the JTAG pin.

What kind of intention do you connect diodes?
Is it okay to omit the diode?



  • I looked at the schematics and found no diodes on the part number you referenced.
    In general, you do not need anything at the JTAG pins beside the the capacitor and resistor on the RST pin.
    However, if you need extra ESD protection for a circuit where the JTAG is exposed, then some external ESD clamping diodes might be needed.
