STM32G071RBT3

STM32G071RBT3 is STMicroelectronics’ STM32G0 family microcontroller. It combines a cost‑efficient 32‑bit ARM Cortex‑M0+ core with a rich set of peripherals for mid‑range embedded apps, including USB, analog, and timing features, in a compact package.
Key points:
- Core and speed: Cortex‑M0+ up to 64 MHz
- Memory: Flash and RAM sized per variant (G071RB devices sit in the mid‑range); check the exact datasheet for your part
- Connectivity and peripherals: USART/LPUART, I2C, SPI, USB Full‑Speed device, (CAN on some SKUs), 12‑bit ADC, DAC/analog blocks, multiple timers, DMA, CRC, and interpolation of mixed signals
- Special features: LCD controller on certain packages; capacitive touch sensing possible
- Power: wide VDD range (roughly 2.0–3.6 V) with multiple low‑power modes
- Package: RBT3 denotes a specific package option (verify exact pin count)
- Tools: supported by STM32CubeIDE with HAL/LL libraries and example code
- Typical use: small to mid‑range MCU tasks—IoT nodes, sensors, control applications
Note: confirm exact flash/RAM and peripherals from the datasheet for your exact package/marking.
