Timers and watchdogs
The STM32F050xx family devices include up to six general-purpose timers, one basic timer
and an advanced control timer.
Table 3
Calendar with subsecond, seconds, minutes, hours (12 or 24 format), week day, date,
month, year, in BCD (binary-coded decimal) format.
Automatically correction for 28, 29 (leap year), 30, and 31 day of the month.
Programmable alarm 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.
2 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
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.
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.
