Hi, I am doing a comparison between the STM32L432 and the STM32L412. However, I observed a discrepancy in the STM32L412 power values under Table 4. STM32L412xx modes overview, LPRun and LPSleep are showing the same value. Is this correct?

Looks like an error in DS12469 Rev 9 data sheet. Would expect a value slightly below STM32L432xx (DS11451 Rev 4). Sleep is a feature of the Arm Cortex-M4 core.

Could you please confirm if this error is officially acknowledged and if there is an errata or updated documentation addressing the discrepancy? If not, may I assume that it's simply incorrect data in the datasheet?

Hello @akhilfrancis;
I confirm that this is a typo and will be corrected in the coming version of the datasheet.
Please use detailed "Table 40. Current consumption in Sleep and Low-power sleep modes, flash ON" and "Table 42. Current consumption in Low-power sleep modes, flash in power-down" in DS12469 for LPSleep current consumption.
Thank you.
