STM32L496XX Datasheet, PDF (30/263 Pages) STMicroelectronics – 25 nA Shutdown mode

Functional overview
STM32L496xx
• Shutdown mode
The Shutdown mode allows to achieve the lowest power consumption. The internal
regulator is switched off so that the V_CORE domain is powered off. The PLL, the HSI16,
the MSI, the LSI and the HSE oscillators are also switched off.
The RTC can remain active (Shutdown mode with RTC, Shutdown mode without RTC).
The BOR is not available in Shutdown mode. No power voltage monitoring is possible
in this mode, therefore the switch to Backup domain is not supported.
SRAM1, SRAM2 and register contents are lost except for registers in the Backup
domain.
The device exits Shutdown mode when an external reset (NRST pin), a WKUP pin
event (configurable rising or falling edge), or an RTC event occurs (alarm, periodic
wakeup, timestamp, tamper).
The system clock after wakeup is MSI at 4 MHz.
