Ultralow power continuum
The Ultralow power STM8L151xx and STM8L152xx are fully pin-to-pin, software and feature
compatible. Besides the full compatibility within the family, the devices are part of
STMicroelectronics microcontrollers UtraLowPower strategy which also includes
STM8L101xx and STM32L15xxx. The STM8L and STM32L families allow a continuum of
performance, peripherals, system architecture, and features.
They are all based on STMicroelectronics 0.13 µm ultralow leakage process.
The STM8L151xx and STM8L152xx are pin-to-pin compatible with STM8L101xx devices.
The STM32L family is pin-to-pin compatible with the general purpose STM32F family.
Please refer to STM32L15x documentation for more information on these devices.
Performance
All families incorporate highly energy-efficient cores with both Harvard architecture and
pipelined execution: advanced STM8 core for STM8L families and ARM Cortex™-M3 core
for STM32L family. In addition specific care for the design architecture has been taken to
optimize the mA/DMIPS and mA/MHz ratios.
This allows the Ultralow power performance to range from 5 up to 33.3 DMIPs.
Shared peripherals
STM8L151xx/152xx and STM32L15xx share identical peripherals which ensure a very easy
migration from one family to another:
