Hi, I am using Congatec QMX6 module which has Freescale IMX6 cortex A9 1GHZ single core processor. I want to provide a coin cell for the RTC backup so what would be the current consumption for the RTC? As stated by congatec it is 1.45UA at 20 degC and by freescale datasheet it is 41UA. Please help me to calculate proper consumption.

Hi Neeraj

typical value is 15-20uA, however at high

temperature limit it may be as given in

IMX6DQCEC Table 8. Maximum Supply Currents.

It can not be calculated/predicted by any formula.

Best regards

igor

Hi Igor,

I am confused which value I will take. In Table 8 for

VDD_SNVS_IN

, it is 275uA under normal conditions?

Hi Neeraj

this is at high temperature limit (95C for

Standard Consumer ).
