STM32G071GBU6N

STM32G071GBU6N is a mid‑density MCU from STMicroelectronics’ STM32G0 family. It uses an ARM Cortex‑M0+ core running up to 64 MHz. Memory varies by variant; for this part family, typical devices offer around 128 KB of flash and 16 KB of RAM (check the exact datasheet for BU6N). Peripherals include USB Full‑Speed device, multiple UARTs/USARTs, SPI, I2C, 12‑bit ADCs, DAC, op‑amps and comparators, plus timers, RTC, and DMA. Some G0 parts also feature an LCD controller. It operates from a 1.65–3.6 V supply and supports low‑power modes suitable for battery-powered applications. The device comes in a 48‑pin BU package. Development is supported by the standard STM32CubeMX tooling and HAL/LL libraries, with a broad ecosystem of middleware and example projects. Ideal for USB‑enabled, cost‑efficient embedded applications requiring mixed digital/analog peripherals. For exact Flash/RAM size, package options, and feature set, refer to the official datasheet for STM32G071GBU6N.
