I need some help with the Atmel XMega128A3U.
I have found some strange behaviour with the brownout detection voltage level...
The latest version of the Xmega128A3U datasheet on pg.: 113 (link) says the BOD voltage level ranges from 1.6V to 3.0V. But if I program the FUSE bits to 3.0V - with Atmel studio 7 - after programming, the device stays in reset state with 3.3V supply voltage, and only starts when I increase the supply voltage to 3.55V
I did some research and I found that in the Xmega128A3 datasheet on pg.: 109 (link) says the BOD voltage level ranges from 1.6V to 3.4V and the binary coded voltage levels matches the real ("measured") voltage levels with my Xmega128A3U CPU.... A have measured every possible BOD voltage settings, and all of them matching the levels in the Xmega128A3 datasheet.. but my CPU is Xmega128A3U!
I have attached a photo about my CPU's device marking, which says this is a "ATXMEGA128A3 AU 1710"
My question is, is there a mistake in the datasheet, or the device marking is wrong on my IC?
