Description

2.3

Ultra-low-power continuum

The ultra-low-power STM8L151x6/8, STM8L152x6/8 and STM8L162x8 are fully pin-to-pin,

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

are part of STMicroelectronics microcontrollers ultra-low-power strategy which also includes

STM8L101 line, STM8L151/152 lines, and STM8L162 line. 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 STM8L151xx and STM8L152xx are pin-to-pin compatible with STM8L101xx devices.

The STM32L family is pin-to-pin compatible with the general purpose STM32F family.

Please refer to STM32Lxxxxx 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

STM8L15xx6/8 and STM32Lxxxxx share identical peripherals which ensure a very easy

migration from one family to another:

•

Analog peripherals: ADC1, DAC1/DAC2, and comparators COMP1/COMP2

•

Digital peripherals: RTC and some communication interfaces

Common system strategy

To offer flexibility and optimize performance, the STM8L15xx6/8 and STM32Lxxxxx devices

use a common architecture:

•

Same power supply range from 1.65 to 3.6 V. For STM8L101xx and medium-density

STM8L15xxx, the power supply must be above 1.8 V at power-on, and go below 1.65 V

at power-down.

•

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 STM8L15xx6/8 and STM32Lxxxxx

including power-on reset, power-down reset, brownout reset and programmable

voltage detector.

Features

STMicroelectronics ultra-low-power continuum also lies in feature compatibility:

•

More than 10 packages with pin counts from 20 to 100 pins and size down to 3 x 3 mm

•

Memory density ranging from 4 to 128 Kbyte
