Description

2.2

Ultra-low-power device continuum

The ultra-low-power family offers a large choice of core and features, from 8-bit proprietary

core up to Arm® Cortex®-M4, including Arm® Cortex®-M3 and Arm® Cortex®-M0+. The

STM32Lx series are the best choice to answer your needs in terms of ultra-low-power

features. The STM32 Ultra-low-power series are the best solution for applications such as

gas/water meter, keyboard/mouse or fitness and healthcare application. Several built-in

features like LCD drivers, dual-bank memory, low-power Run mode, operational amplifiers,

128-bit AES, DAC, crystal-less USB and many other definitely help you building a highly

cost optimized application by reducing BOM cost. STMicroelectronics, as a reliable and

long-term manufacturer, ensures as much as possible pin-to-pin compatibility between all

STM8Lx and STM32Lx on one hand, and between all STM32Lx and STM32Fx on the other

hand. Thanks to this unprecedented scalability, your legacy application can be upgraded to

respond to the latest market feature and efficiency requirements.
