How to migrate across STM32 series

2.1

STM32 series general overview

The STM32 platform forms a strong foundation with a broad and growing portfolio. With new
products addressing new applications, the complete STM32 product series now comprises
three series, STM32F-1, STM32F-2 and STM32L-1, each dedicated to a specific segment:
●
STM32 F-1: The general-purpose F-1 series addresses a wide range of applications,
from the lowest, price-sensitive designs to computing-intensive, high memory footprint
ones.
The F-1 series is a complete series whose members are fully pin-to-pin, software and
feature compatible.

●
STM32 F-2: The F-2 series provides the highest performance for computing-intensive
applications and advanced connectivity. The F2 series maintains compatibility with the
F1 series.
●
STM32 L-1: Designed for ultra-low-power applications that are energy-aware and seek
to achieve the absolute lowest power consumption. The L-1 series maintains
compatibility with the F1 series.
