ST has confirmed that STM32G070 uses same silicon as STM32G081, thus we're considering use it as the alternative to STM32G081 due to availability problems.STM32G070 lacks BOR feature and CEC hw block acc. to datasheet but we have proven by trial that...

I have tested Power On Reset / Power Down Reset (POR/PDR) voltage threshold on two STM32G070RBT6 sourced by different suppliers. The threshold isn't matching the specified voltage 2.06<VPOR<2.14 and 1.96<VPDR<2.04 but it fits values stated in STM32G0...

we were lucky to get reel of G070 these days

AES unit isn't being used, CEC block is main reason for choosing STM32G081. In the meantime, we've replaced it by software CEC solution so no reason to keep using G081.Apart of that thanks for confirmation, we cannot rely on G070 untested BOR feature...

thanks for confirmation, I was referring to real measurement done on G070 which violates POR/PDR specification as you can see attached.BOR disabled, POR/PDR active, thresholds out of specBOR enabled, set to highest Level, thresholds within spec

Hi Bruno, thanks for quick response. Functionality of target application is strongly dependant on POR/PDR threshold. If understood correctly POR/PDR threshold voltage of G070 cannot be guaranteed within G081 spec therefore lower values are specified....
