The STMicroelectronics STM32G071K8U6 is a mainstream 32-bit microcontroller from the STM32G0 family, built around a high-performance Arm Cortex-M0+ core running at up to 64MHz. This exact K8 variant integrates 64KB of Flash memory and 36KB of SRAM, together with memory protection, DMA, and multiple low-power operating modes for industrial, appliance, consumer, and IoT applications.
The device operates from a 1.7V to 3.6V supply and integrates a 12-bit ADC capable of approximately 2.5MSps, with hardware oversampling that can increase effective resolution up to 16 bits. It also includes two 12-bit DAC channels and two fast low-power analog comparators for sensing, monitoring, and mixed-signal control applications.
Communication peripherals include four USARTs, one low-power UART, two I²C interfaces, two SPI interfaces with one supporting I²S, and HDMI CEC. I²C supports Fast-mode Plus operation up to 1Mbit/s, while SPI supports data rates up to 32Mbit/s. The STM32G071 family also integrates USB Type-C Power Delivery controller functionality, RTC, DMA, and an extensive timer set.
The STM32G071K8U6 ordering code identifies a 32-pin device with 64KB Flash in a UFQFPN package and -40°C to +85°C ambient temperature grade. Its UFQFPN32 package measures 5 × 5mm with a 0.5mm pitch. ST currently lists the exact orderable part as Active, Industrial grade, and Ecopack2 compliant.
