STM32L152R6T6A

Replacements:

Instead of STM32F042G4U6 i want "This":https://www.digikey.de/de/products/detail/stmicroelectronics/STM32F042G6U6TR/7313044 . It has 32KB Flash so bootloader is possible.

h2. Design guides

* 100nF on NRST

* VDD: n x 100 nF + 1 x 4.7 μF

* VDA: 10 nF + 1 μF

* BOOT: 10K to ground

* NRST: 10K to VDD an STM32 examples

h2. Low power modes

SLEEP MODE: CPU CLK is turned OFF; no effect on other clocks or analog clock sources. The current consumption is HIGHEST in this mode, compared to other Low Power Modes

* Use HAL_PWR_EnableSleepOnExit() to automatically go to sleep again when an ISR has finished
