Functional overview

Figure 2. Medium-density value line STM8L052C6 clock tree diagram

The HSE clock source can be either an external crystal/ceramic resonator or an external source (HSE

bypass). Refer to Section HSE clock in the STM8L15x and STM8L16x reference manual (RM0031).

The LSE clock source can be either an external crystal/ceramic resonator or a external source (LSE

bypass). Refer to Section LSE clock in the STM8L15x and STM8L16x reference manual (RM0031).

Low-power real-time clock

The real-time clock (RTC) is an independent binary coded decimal (BCD) timer/counter.

Six byte locations contain the second, minute, hour (12/24 hour), week day, date, month,

year, in BCD (binary coded decimal) format. Correction for 28, 29 (leap year), 30, and 31

day months are made automatically.It provides a programmable alarm and programmable

periodic interrupts with wakeup from Halt capability.



Periodic wakeup time using the 32.768 kHz LSE with the lowest resolution (of 61 µs) is

from min. 122 µs to max. 3.9 s. With a different resolution, the wakeup time can reach

36 hours.



Periodic alarms based on the calendar can also be generated from every second to

every year.
