Tamper and backup registers
WebThe RTC embeds 80 bytes of backup registers, used to preserve data when the main supply is off. These backup registers can be used to store secure data, as they are erased when a tamper event is detected on the tamper pins. The RTC consumes 315 nA at 1.8 V, including the LSE power consumption. Web• Alarm A, Alarm B, Wakeup interrupt, Time-stamp, Tamper detection • Digital calibration circuit (periodic counter correction) to achieve 0.95 ppm accuracy • Time-stamp function for event saving with sub second precision (1 event) • Backup registers which are reset when an tamper detection event occurs. • 64 bytes for STM32F30x
