STM32G483xE Microcontrollers STMicroelectronics STM32G483xE Microcontrollers are based on high-performance Arm® Cortex®-M4 32-bit RISC core and operate at 170MHz frequency. This Cortex-M4 core features a single-precision Floating-Point Unit (FPU) that supports all the Arm single-precision data-processing instructions and all the data types. The STM32G483xE MCUs include embedded high-speed memories, Flexible Static Memory Controller (FSMC) for static memories, and a quad SPI flash memory interface. These MCUs embed an extensive range of enhanced I/Os, peripherals that allow mathematical/arithmetic function acceleration, several protection mechanisms for embedded flash memory, and SRAM.
