MPC5125 RTC Power Issue

Discussion created by Andrea Cisco on Apr 26, 2011

I'm tring to use the battery for the RTC on the MPC5125 tower module.

As told by the User Manual I bought from Digikey the Panasonic capacitor.

But when I disconnect the power the consumption of the RTC part is 2-3 mA (form the MPC5125 reference manual they should be 40uA)  , so the date/time remains only few seconds.

Somebody solved this problem ?
