STM32G031G6U6 Description

The high-performance Arm? Cortex?-M0+ 32-bit RISC processor of the STM32G031G6U6 mainstream microcontroller operates at up to 64 MHz frequency. They are appropriate for a wide range of applications in the consumer, industrial, and appliance domains. They are prepared for the Internet of Things (IoT) solutions because of their high level of integration.

A memory protection unit (MPU), high-speed embedded memories (8 Kbytes of SRAM and up to 64 Kbytes of Flash program memory with reading, write, proprietary code protection, and securable region), DMA, a wide range of system functions, improved I/Os, and peripherals are all included in the devices. A 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 operating at up to twice 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 are among the standard communication interfaces provided by the devices.

The gadgets function in temperatures between -40 and 125 °C. With supply voltages ranging from 1.7 V to 3.6 V, they can function. Low-power applications can be created thanks to optimized dynamic consumption, a wide range of power-saving settings, low-power timers, and low-power UART.

RTC and backup registers can be kept powered by VBAT direct battery input.

Packages with 8 to 48 pins are available for the devices.
