The STM32G030C8T6 is a mainstream value-line 32-bit microcontroller from STMicroelectronics based on the ARM Cortex-M0+ core. It belongs to the STM32G0 series, which is designed as an optimal balance between performance, cost, and power efficiency for entry-level embedded applications.

The device features a 64 MHz ARM Cortex-M0+ CPU providing efficient instruction execution for cost-sensitive embedded systems. It integrates 64 KB Flash memory with protection features and 8 KB SRAM with hardware parity checking for fail-critical applications.

Key advantages include a comprehensive set of low-power modes (Sleep, Stop, Standby) that enable battery-powered applications with standby current as low as 2 µA. The device supports VBAT supply to keep the RTC and backup registers powered when main power is off.

The LQFP-48 package provides 44 fast I/O pins, all mappable on external interrupt vectors, with multiple 5V-tolerant I/Os for direct interfacing with 5V logic. The device supports Serial Wire Debug (SWD) for programming and debugging using only 2 pins.

The STM32G030C8T6 is fully supported by ST’s ecosystem including STM32CubeMX, STM32CubeIDE, HAL libraries, and major third-party toolchains (Keil MDK, IAR Embedded Workbench), simplifying development from prototyping to production
