The STM32G431x6/x8/xB devices are based on the high-performance Arm® Cortex®-M4 32-bit RISC core. They operate at a frequency of up to 170 MHz. The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all the Arm single-precision data-processing instructions and all the data types. It also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) which enhances the application’s security.
This blog will introduce STM32G431RBT6 systematically from its features, pinout to its specifications, applications, also including STM32G431RBT6 datasheet and so much more.
