Ultralow power device continuum
The ultralow power STM32L151xx and STM32L152xx 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 and STM32L15xxx share identical peripherals which ensure a very easy
migration from one family to another:
●
●
Common system strategy
To offer flexibility and optimize performance, the STM8L15xx and STM32L15xx families use
a common architecture:
●
●
●
●
●
Features
ST ultralow power continuum also lies in feature compatibility:
●
●
Analog peripherals: ADC, DAC, and comparators
Digital peripherals: RTC and some communication interfaces
Same power supply range from 1.65 V to 3.6 V, (1.65 V at power down only for
STM8L15xx devices)
Architecture optimized to reach ultralow consumption both in low power modes and
Run mode
Fast startup strategy from low power modes
Flexible system clock
Ultrasafe reset: same reset strategy including power-on reset, power-down reset,
brownout reset and programmable voltage detector.
More than 10 packages with pin count from 20 to 100 pins and size down to 3 x 3 mm
Memory density ranging from 4 to 128 Kbytes
