The STM32L0x1 Access line is the entry point of the STM32L0 series offering tiny packages such as the WLCSP25 (2x2mm), up to 192-Kbytes of Flash memory, up to 20-Kbytes of RAM and up to 6Kbytes 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.

This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course. This is our first STM32 based on Cortex-M33 and its Trustzone and using specific ST security implementation - watch the video to find out more!
The STM32L5 is based on Arm? Cortex-M33 and TrustZone? technology combined with STMicroelectronics security implementation. On your STM32L562E-DK discovery board, TrustZone is disabled (factory setting) and you can develop as on any other STM32 device. This video shows how to enable TrustZone on STM32L562E-DK discovery using STM32CubeProgrammer and create, compile and debug or run a new project with STM32CubeIDE. It also shows how to open an example project delivered in STM32CubeL5 MCU Package, modify, compile and debug or run it. For further information, you can refer to AN5394 and AN5424 application notes.
MadeForSTM32? is a new quality label delivered by ST, which is granted after an evaluation process. It helps engineers identify third party solutions with the highest level of integration and quality for the STM32 microcontrollers' ecosystem. MadeForSTM32? is offered to members of the ST Partner Program who want to go one step further in our collaboration, with the overall objective of contributing to a high-quality STM32 ecosystem.
