STMicroelectronics, 32bit ARM Cortex M4, STM32G Microcontroller MCU, 170MHz, 256 kB Flash, 80-Pin LQFP

The STMicroelectronics Microcontrollers 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.
