MCU Finder App: Select The Right MCU For Your Design!


Embedded developers can now easily find the MCU part number that best fits their application with the new ‘MCU Finder for PC’ application from ST. Developers can quickly find the data and technical resources they need to support their microcontroller projects directly from their desktop environment which is used for application development.

Users can search the entire range of over 700 STM32 (32-bit ARM Cortex-M) and over 125 STM8 8-bit MCU part numbers, based on up to 54 criteria for the STM32 and 20 criteria for the STM8 family.

Searching is based on multiple criteria including core type, CPU frequency, memory, price, package, I/Os, temperature grade and peripherals such as control, timers, analog, connectivity, multimedia and security. Users can also buy devices online.

The PC version (ST-MCU-FINDER-PC) of the app leverages features of ST’s popular MCU Finder mobile app (ST-MCU-FINDER). It  provides easy-to-use selection tools, self-maintaining documentation, and connections to MCU communities.


The app is available for Windows, macOS, and Linux platforms.

Development can begin immediately after device selection by downloading the STM32CubeMX initialization-code generator directly from the MCU Finder for PC.

The app also connects users with developer communities on popular social platforms such as Facebook, Twitter, STM32’s YouTube channel and the new ST Community of more than 40,000 members.

ST’s MCU Finder for PC is available now, and can be downloaded free of charge from
