STM32G031F4P6 Description
STM32G031x4/x6/x8 mainstream microcontrollers are based on a high-performance ARM Cortex - M0mm 32-bit RISC core and run at up to 64 MHz. They provide highly integrated, suitable for a wide range of consumer, industrial and home appliance applications, and prepare for Internet of things (IoT) solutions. These devices include memory protection units (MPU), high-speed embedded memory (8K bytes of SRAM and up to 64K bytes of flash program memory with read protection, write protection, proprietary code protection and security areas), DMA, a wide range of system features, enhanced Igamo and peripherals. These devices provide standard communication interfaces (two I2C, two SPI/, one I2S and two USART), a 12-bit ADC (2.5 MSPS) with up to 19 channels, an internal reference voltage buffer, a low-power RTC, an advanced control PWM timer running up to twice the frequency of CPU, four general purpose 16-bit timers, one 32-bit general timer, two low-power 16-bit timers, Two watchdog timers and a SysTick timer.
