The ST-MCU-FINDER-PC application allows exploring and connecting to the complete portfolio of STM32 Arm® Cortex®-M and STM8 microcontrollers, and development boards directly from the developer’s desktop environment.

ST-MCU-FINDER-PC features easy-to-use selection tools, self-maintaining documentation, and connections to MCU communities.

Users find the MCU and development board part number that best fits their application thanks to an easy search with 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 on line.

Developers have quick access to data and technical resources to support their microcontroller projects. The technical documentation for a selected device (including datasheets, reference manuals, application notes, user manuals, programming manuals, errata sheets) is available in one place and can be downloaded for off-line viewing. Documents are automatically updated with their latest version.

The development begins immediately after the device selection by launching STM32CubeMX initialization-code generator directly from the application.

ST-MCU-FINDER-PC connects users with developer communities on popular social platforms such as Facebook™, Twitter™, STM32’s YouTube™ channel, and ST Community.
