Clocks
Three different clock sources can be used to drive the system clock (SYSCLK):
●
●
●
The devices have the following two secondary clock sources:
●
●
Each clock source can be switched on or off independently when it is not used, to optimize
power consumption.
HSI oscillator clock
HSE oscillator clock
PLL clock
40 kHz low speed internal RC (LSI RC) which drives the independent watchdog and
optionally the RTC used for Auto-wakeup from Stop/Standby mode.
32.768 kHz low speed external crystal (LSE crystal) which optionally drives the real-
time clock (RTCCLK)
