The STM32L0x1 Access line is the entry point of the STM32 L0 series offering tiny packages such as the WLCSP32, up to 64 Kbytes of Flash, up to 8 Kbytes of RAM and up to 2 Kbytes of embedded EEPROM. This line also gives access to the autonomous peripherals, real-time clock, low-power time clock, hardware encryption and ultra-low-power 12-bit ADC with 48 µA budget consumption at 100 Ksps.
The STM32L0x1 line is the perfect fit for applications such as mice or keyboards, as a result of the very low active current consumption, and well fits industrial applications such as gas and water meters, thanks to the embedded hardware encryption (AES 128-bit) and peripherals available in ultra-low-power mode.
