Functional overview
STM32F301x6 STM32F301x8
The RTC is an independent BCD timer/counter. It supports the following features:
Calendar with subsecond, seconds, minutes, hours (12 or 24 format), week day, date,
month, year, in BCD (binary-coded decimal) format.
Automatic correction for 28, 29 (leap year), 30, and 31 days of the month.
Two programmable alarms with wake up from Stop and Standby mode capability.
On-the-fly correction from 1 to 32767 RTC clock pulses. This can be used to
synchronize it with a master clock.
Digital calibration circuit with 1 ppm resolution, to compensate for quartz crystal
inaccuracy.
Two anti-tamper detection pins with programmable filter. The MCU can be woken up
from Stop and Standby modes on tamper event detection.
Timestamp feature which can be used to save the calendar content. This function can
be triggered by an event on the timestamp pin, or by a tamper event. The MCU can be
woken up from Stop and Standby modes on timestamp event detection.
17-bit Auto-reload counter for periodic interrupt with wakeup from STOP/STANDBY
capability.
The RTC clock sources can be:
A 32.768 kHz external crystal
A resonator or oscillator
The internal low-power RC oscillator (typical frequency of 40 kHz)
The high-speed external clock divided by 32.
