STMicroelectronics STM32G071G8U6

Overview

STM32G071G8U6 from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller in UFQFPN28 package, operating up to 64 MHz with 128 KB Flash, 36 KB SRAM, and integrated USB Type-C Power Delivery controller. It features two 12-bit DACs, a 12-bit 0.4 µs ADC (16-channel), four USARTs (including ISO7816/LIN/IrDA support), and operates across 1.7–3.6 V supply for industrial sensor nodes and smart power peripherals.

For engineers reviewing the STM32G071G8U6 datasheet, STM32G071G8U6 pinout, STM32G071G8U6 application, or STM32G071G8U6 equivalent, key selection criteria include its dual DAC capability, USB-C PD controller integration, 60 fast I/Os with 5 V tolerance, and support for multiple low-power modes (Stop/Standby/Shutdown) with RTC wakeup - critical for battery-powered edge devices requiring precise analog control and secure power negotiation.

Technical Context

The STM32G071G8U6 implements an Arm Cortex-M0+ core with MPU, supporting TrustZone-like memory protection via securable flash area and readout protection levels. Its clock system combines 4–48 MHz HSE, 32 kHz LSE with calibration, and ±1% internal 16 MHz HSI with PLL - enabling precise timing for synchronous communication and motor control.

Analog subsystem includes two rail-to-rail 12-bit DACs with sample-and-hold, a 12-bit ADC with hardware oversampling up to 16-bit resolution, and two programmable comparators. Communication stack integrates two Fast-mode Plus I²C (1 Mbit/s), four USARTs (two with ISO7816), two SPIs (32 Mbit/s), HDMI CEC, and dedicated USB Type-C PD controller - all accessible via 60 mappable GPIOs with interrupt capability.

FAQ

What is the maximum operating frequency and supported voltage range?

The STM32G071G8U6 operates at up to 64 MHz and supports a supply voltage range of 1.7 V to 3.6 V. This allows direct compatibility with single-cell Li-ion (3.0–3.6 V), coin-cell (1.7–3.0 V), and standard 3.3 V logic rails. The internal voltage regulator maintains stable core operation across this range, with programmable brownout reset (BOR) and voltage detector (PVD) for robust power monitoring.

Does STM32G071G8U6 support USB-C Power Delivery negotiation without external components?

Yes - it integrates a dedicated USB Type-C Power Delivery controller compliant with PD 3.0. This hardware block handles BMC decoding, policy engine execution, and VCONN switching, eliminating the need for external PD PHY or discrete logic. Only external power path MOSFETs and current-sense resistors are required to implement full sink/source negotiation.

How many analog-to-digital and digital-to-analog channels does it provide?

The device includes one 12-bit ADC with up to 16 external input channels and hardware oversampling (up to 16-bit effective resolution), plus two independent 12-bit DACs with sample-and-hold. These are physically separate peripherals - the ADC supports simultaneous sampling on multiple channels via DMA, while each DAC operates autonomously with configurable trigger sources and output buffers.

What low-power modes are available and what is the typical current in Standby mode?

It supports Sleep, Stop, Standby, and Shutdown modes. In Standby mode with RTC and backup registers active, typical current is 0.32 µA at 25°C (VDD = 3.3 V). This mode retains RTC calendar, backup SRAM, and wakes via RTC alarm, external interrupt, or I²C address match - ideal for infrequent-event sensing with decade-scale battery life.
