Real-time clock (RTC), backup SRAM and backup registers
The backup domain of the STM32F405xx and STM32F407xx includes:
●
●
●
The real-time clock (RTC) is an independent BCD timer/counter. Dedicated registers contain
the second, minute, hour (in 12/24 hour), week day, date, month, year, in BCD (binary-coded
decimal) format. Correction for 28, 29 (leap year), 30, and 31 day of the month are
performed automatically. The RTC provides a programmable alarm and programmable
periodic interrupts with wakeup from Stop and Standby modes. The sub-seconds value is
also available in binary format.

4 Kbytes of backup SRAM
20 backup registers
Startup in regulator OFF: slow V
- power-down reset risen after V
Startup in regulator OFF mode: fast V
- power-down reset risen before V
