STM8L052C6

Description

2.2

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
