Ultra low power continuum

The ultra low power value line STM8L05xxx and STM8L15xxx are fully pin-to-pin, software

and feature compatible. Besides the full compatibility within the STM8L family, the devices

are part of STMicroelectronics microcontrollers ultra low power 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 ultra-low leakage process.

Note:

The STM8L05xxx is 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 ultra low power performance to range from 5 up to 33.3 DMIPs.

Shared peripherals

STM8L05x, STM8L15x and STM32L15xx share identical peripherals which ensure a very

easy migration from one family to another:

●

Analog peripheral: ADC1

●

Digital peripherals: RTC and some communication interfaces

Common system strategy

To offer flexibility and optimize performance, the STM8L and STM32L devices use a

common architecture:

●

Same power supply range from 1.8 to 3.6 V

●

Architecture optimized to reach ultra-low consumption both in low power modes and

Run mode

●

Fast startup strategy from low power modes

●

Flexible system clock

●

Ultra-safe reset: same reset strategy for both STM8L and STM32L including power-on

reset, power-down reset, brownout reset and programmable voltage detector

Features

ST ultra low power continuum also lies in feature compatibility:

●

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
