STMicroelectronics STM32G483xE Microcontrollers
STMicroelectronics STM32G483xE Microcontrollers are based on the high-performance Arm® Cortex®-M4 32-bit RISC core and operate at a 170MHz frequency. The Cortex-M4 core features a single-precision floating-point unit (FPU) that supports all Arm single-precision data-processing instructions and all data types. The STM32G483xE MCUs from STMicroelectronics include embedded high-speed memories, a 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, protection mechanisms for embedded flash memory, SRAM, and peripherals for mathematical / arithmetic function acceleration.
The STM32G483xE series operates in a -40°C to 125°C temperature range and a 1.71V to 3.6V power supply voltage range. The MCUs feature the following interfaces: four I2C, four SPI, three USART, two UART, one low-power UART, three FDCAN, one SAI, USB Power Delivery Controller (UCPD), and a USB device. The STM32G483xE microcontrollers come with independent power supplies that are supported with analog independent supply input for ADC, DAC, OPAMPs, and comparators.
