STEVAL-IFR003V1 RTC calibration daughterboard based on the M41T83SMY6E to be used with STEVAL-IFS012V1 Data brief Features ■ M41T83 RTC in SOX18 package mounted on daughter card ■ RoHS compliant Description The STEVAL-IFR003V1 is an RTC calibration demonstration daughter card to be used in connection with STEVAL-IFS012V1, a multidevice temperature sensor demonstration motherboard. STEVAL-IFS012V1 supports the demonstration of four RTCs; M41T81S RTC mounted on motherboard, M41T82 (SO-8 package) mounted on separate STEVALIFR001V1 daughter card, M41T83(QFN package) mounted on separate STEVAL-IFR002V1 daughter card, and M41T83 (SOX18 package) mounted on separate STEVAL-IFR003V1 daughter card. STEVAL-IFR003V1 RTC mode of the GUI is chosen through the RTC selection icon on the GUI.
