DA14586 design questions

Hello,

I am about to move my design from the DA14580 to the DA14586 since the old part is not recommended for new designs and I would make use of the internal FLASH.

My understanding is from a schematics point of view, only two pins are different:

#5 (VCC_FLASH) is used to power the FLASH. On the 14580/5 it is nc.

#38 (VDD) is recommended to float. On the 14580 it was VPP and used only when programming OTP (supply 6.7V).

I hope this is correct so far?

However, the Eval Board with the DA14585 (e-da1458xdevkt-b-vb00.pdf) still shows a circuit to generate VPP supply. So to use OTP memory, is VDD/VPP supply required or can VDD pin be always floating?

Thank you

Andreas
