Independent watchdog (IWDG)
The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is
clocked from an independent 40 kHz internal RC and as it operates independently from the
main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog
to reset the device when a problem occurs, or as a free running timer for application timeout
management. It is hardware or software configurable through the option bytes. The counter
can be frozen in debug mode.
System window watchdog (WWDG)
The system window watchdog is based on a 7-bit downcounter that can be set as free
running. It can be used as a watchdog to reset the device when a problem occurs. It is
clocked from the APB1 clock (PCLK1) derived from the main clock. It has an early warning
interrupt capability and the counter can be frozen in debug mode.
SysTick timer
This timer is dedicated to real-time operating systems, but could also be used as a standard
down counter. It features:
●
●
●
●
Real-time clock (RTC) and backup registers
The RTC and the backup registers are supplied through a switch that takes power either
from V
32-bit registers used to store 128 bytes of user application data.
They are not reset by a system or power reset, and they are not reset when the device
wakes up from the Standby mode.
The RTC is an independent BCD timer/counter. Its main features are the following:
●
●
●
●
●
●
●
●
A 24-bit down counter
Autoreload capability
Maskable system interrupt generation when the counter reaches 0
Programmable clock source
Calendar with subsecond, seconds, minutes, hours (12 or 24 format), week day, date,
month, year, in BCD (binary-coded decimal) format.
Automatic correction for 28th, 29th (leap year), 30th and 31st day of the month.
2 programmable alarms with wake up from Stop and Standby mode capability.
Periodic wakeup unit with programmable resolution and period.
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.
3 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.
