If you refer to the only PS at https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52840.html and https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52833.html you will always have the latest version.

The two devices have different memory size so you must as least build the code again for the other device. There are differences in the GPIO mapping as well, so make sure you change that as well.

You can use the nRF52833 on the nRF52840 layout if you don't use the NC pins and REG0 in DCDC mode.

I have continued working through the pinout of the 52840, and have found more IO differences. I am just confirming this is he case and I am not working with an old dataseet ? The reason I am asking is that an Nordic ENhineer has said they were code compatible - but thats not true if those IO were used. Obviously the package is compatible and only needs code to be adapted with reference to those specific IO pins
