Ultra-low-power device continuum
The ultra-low-power STM32L15xxD, STM32L162xD, STM32L15xxC and STM32L162xC
are fully pin-to-pin and software compatible. Besides the full compatibility within the family,
the devices are part of STMicroelectronics microcontrollers ultra-low-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 ultralow leakage process.
Note:
The ultra-low-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.

2.2.1 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.

optimize the mA/DMIPS and mA/MHz ratios.
This allows the ultra-low-power performance to range from 5 up to 33.3 DMIPs.
2.2.2 Shared
peripherals
STM8L15xxx, STM32L15xxx and STM32L162xx share identical peripherals which ensure a
very easy migration from one family to another:
very easy migration from one family to another:
Analog peripherals: ADC, DAC and comparators
Digital peripherals: RTC and some communication interfaces
2.2.3 Common
system
strategy
To offer flexibility and optimize performance, the STM8L15xxx, STM32L15xxx and
STM32L162xx families use a common architecture:
