  • The STM32G031x4/x6/x8 mainstream microcontrollers are based on high-performance Arm® Cortex®-M0+ 32-bit RISC core operating at up to 64 MHz frequency. Offering a high level of integration, they are suitable for a wide range of applications in consumer, industrial and appliance domains and ready for the Internet of Things (IoT) solutions.

    The devices incorporate a memory protection unit (MPU), high-speed embedded memories (up to 64 Kbytes of Flash program memory and 8 Kbytes of SRAM), DMA and an extensive range of system functions, enhanced I/Os and peripherals. The devices offer standard communication interfaces (two I2Cs, two SPIs / one I2S, and two USARTs), one 12-bit ADC (2.5 MSps) with up to 19 channels, an internal voltage reference buffer, a low-power RTC, an advanced control PWM timer running at up to double the CPU frequency, four general-purpose 16-bit timers, a 32-bit general-purpose timer, two low-power 16-bit timers, two watchdog timers, and a SysTick timer.
    The devices operate within ambient temperatures from -40 to 125°C. They can operate with supply voltages from 1.7 V to 3.6 V. Optimized dynamic consumption combined with a comprehensive set of power-saving modes, low-power timers and low-power UART, allows the design of low-power applications.
    VBAT direct battery input allows keeping RTC and backup registers powered.
    The devices come in packages with 8 to 48 pins.
