Description

2.2

Ultra-low-power continuum

The ultra-low-power low-density STM8L151x2/3 devices 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

STM8L101xx and STM8L15xxx. 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.

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

STM8L151xx/152xx and STM8L15xxx share identical peripherals which ensure a very easy

migration from one family to another:

•

Analog peripherals: ADC1 and comparators COMP1/COMP2

•

Digital peripherals: RTC and some communication interfaces

Common system strategy

To offer flexibility and optimize performance, the STM8L151xx/152xx and STM8L15xxx

devices use a common architecture:

•

Same power supply range from 1.8 to 3.6 V, down to 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 STM8L15x and STM32L15xxx 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 Kbyte
