RL78 F12 (R5F109AAJ1745EM405) Debugging Voltage 2.1V VDD?

I have to debug the RL78 F12 with an Voltage of 2.1V VDD. I couldn't find anything about it in the documentation. Is it like the G10 that it needs over 4V to debug or an low voltage OCD Board? I tried to debug and couldn't get a connection to the E1 with less than 3.8V.

  • Hi Frank,
    thank you for your fast reply. It's good to know that the µC can debug with 2.1V. We are working with the IAR Embedded Workbench for Renesas RL78 Functional Safety V3.10.2.2086 and it's not working with an external power supply with 2.1V. It might be the Low Power detection. Do you have any experience with that?
