STM8L051F3

Description

2.2

Ultra-low-power continuum

STM8L051F3 is part of STM8’s ultra-low-power value line on which all the devices are 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 the STM8L001xx, STM8L101xx and STM32L15xxx 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 ultra-low leakage process.

Note:

STM8L051F3 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 the STMicroelectronics ultra-low-power families incorporate highly energy-efficient cores

with both Harvard architecture and pipelined execution: advanced STM8 core for STM8L

families and ARM® 32-bit 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

The STM8L05xxx, STM8L15xxx and STM32L15xxx devices 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
