Ultralow power device continuum
The ultralow power STM32L15xxD, STM32L162xD, and STM32L15xxC are fully pin-to-pin,
software and feature compatible. Besides the full compatibility within the family, the devices
are part of STMicroelectronics microcontrollers ultralow power strategy which also includes
STM8L101xx and STM8L15xx devices. 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 ultralow power STM32L and general-purpose STM32Fxxxx families are pin-to-pin
compatible. The STM8L15xxx devices are pin-to-pin compatible with the STM8L101xx
devices. Please refer to the STM32F and STM8L 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
STM8L15xxx, STM32L15xxx, and STM32L162xx share identical peripherals which ensure
a very easy migration from one family to another:
●
●
Common system strategy
To offer flexibility and optimize performance, the STM8L15xxx, STM32L15xxx, and
STM32L162xx families use a common architecture:
