topic How much is the power consumption for RTC? in i.MX Processors https://community.nxp.com/t5/i-MX-Processors/How-much-is-the-power-consumption-for-RTC/m-p/685211#M105979 <HTML><HEAD></HEAD><BODY><P>Hi, I wanted to know how the i.MX6UL handles the RTC. From the datasheet I seem to have understood&nbsp;that the RTC power consumption to be on is in the order of hundred of uA. In my PCB there is no space for a coin cell so I want to use a supercap to supply the RTC even when all system is off. The problem is that in this case the duration of the supercap is much lower than a coin cell because of the elevated RTC power consumption; so I want to ask if the RTC power consumption is really so excessive that I'm not allowed to use a Supercap.</P><P>Thanks</P></BODY></HTML> Tue, 13 Jun 2017 14:05:25 GMT jacopoagostini 2017-06-13T14:05:25Z How much is the power consumption for RTC? https://community.nxp.com/t5/i-MX-Processors/How-much-is-the-power-consumption-for-RTC/m-p/685211#M105979 <HTML><HEAD></HEAD><BODY><P>Hi, I wanted to know how the i.MX6UL handles the RTC.
