Shenzhen Mingjiada Electronics Co., Ltd. new original sale ST microcontroller STM32G031K8U6TR Mainstream Arm Cortex-M0+ MCU with 64 KB Flash memory, 8 KB RAM, 64 MHz CPU, 2x USART, timer, ADC and communication interface, 1.7-3.6V

Device Description:

The STM32G031K8U6TR mainstream microcontrollers are based on the high-performance Arm® Cortex®-M0+ 32-bit RISC core and operate up to 64 MHz.These microcontrollers are highly integrated and suitable for a wide range of applications in the consumer, industrial, and appliance sectors and are ready for Internet of Things (IoT) solutions.

The devices integrate a memory protection unit (MPU), high-speed embedded memory (8 kilobytes of SRAM and up to 64 kilobytes of Flash program memory with read protection, write protection, proprietary code protection, and protectable regions), DMA, a wide range of system functions, enhanced I/O, and peripherals. The devices provide standard communication interfaces (two I2C, two SPI/one I2S, and two USART), a 12-bit ADC (2.5 MSps) (up to 19 channels), an internal voltage reference buffer, a low-power RTC, a high-level control PWM timer running at up to twice the CPU frequency, four general-purpose 16-bit timers, a 32-bit general-purpose timer, and two I/O peripherals. 32-bit general-purpose timer, two low-power 16-bit timers, two watchdog timers, and a SysTick timer.

The devices operate in a -40 to 125°C ambient temperature range with supply voltages from 1.7 V to 3.6 V. Optimised dynamic power consumption combined with a full suite of power-saving modes, low-power timers, and low-power UARTs enable low-power application designs.
