The STM32G070CBT6 is an Arm Cortex-M0+ 32-bit microcontroller from STMicroelectronics offering 128 KB Flash and 36 KB SRAM. It provides a high level of integration suitable for consumer, industrial, and IoT applications. The device features a comprehensive peripheral set including a 12-bit ADC at 2.5 MSPS, 4 USARTs, 2 I2C, 2 SPI, and 11 timers. Its optimized dynamic consumption and comprehensive power-saving modes enable low-power application designs.

The STM32G070CBT6 is built on the Arm Cortex-M0+ processor with a 2-stage pipeline and MPU for memory protection. The AHB bus matrix connects the CPU to Flash (with prefetch and cache), SRAM, and the 7-channel DMA controller. Peripherals are accessed through APB buses. The ADC performs 12-bit successive approximation conversions at up to 2.5 MSPS with hardware oversampling for enhanced resolution. Power modes include Run, Sleep, Stop, and Standby, with VBAT backup for RTC and backup registers. The internal 16 MHz RC oscillator with PLL option eliminates the need for external crystals in many applications.
