The STM32G0 Series is not simply another Arm® Cortex®-M0+ microcontroller. It is setting a new definition of what an efficient microcontroller must offer. This is all about best optimization, down to each and every detail, to offer the best value for money and allow you to achieve your goals with the minimum BOM cost and the maximum flexibility for upgrades.

STM32G0 offers a Cortex®-M0+ core at 64 MHz as well as a robust architecture with a Securable Memory Area, more RAM and Flash, numerous I/Os, and a more extensive integration of components to simplify the overall PCB design significantly.

  • Securable Memory Area.
  • Safe Firmware upgrade / Install
  • Easy to configure thanks to the intuitive and graphic STM32CubeMX configuration tool.
  • Easy to develop based on the Hardware Abstraction Layer library (HAL) or the lowlayer library (LL) allowing maximum re-use and faster time-to-market.



The STM32G0x0 Value Line features an Arm® Cortex®-M0+ core and runs at speeds up to 64 MHz. Setting the lowest ever price point, the STM32G0x0 Value Line makes no compromise on what matters. The STM32G0x0 Value Line comes with a very accurate internal clock making an external oscillator useless, a full set of high performing peripherals such as a faster 12-bit ADC, advanced and flexible timers, calendar RTC and communication peripherals such as the I²C, USART and SPI.


STM32G0x1 offers upgraded capabilities towards IoT and integrated functions. STM32G0x1 devices answer the need for higher performance in analog, low-power operations or more control on secure transactions, such as the IoT applications, home-entertainment products, appliances and industrial equipment. It supports a higher temperature range up to 125 °C and a wide set of package types such as WLCSP, UFBGA, TSSOP, QFP and QFN packages.
