STMicroelectronics STM32G071G8U6N

Overview

STM32G071G8U6N 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 supports -40°C to 105°C operation, features dual 12-bit DACs, 12-bit ADC with hardware oversampling, and four USARTs including ISO7816/LIN/IrDA support - deployed in industrial sensor nodes requiring secure, low-power connectivity and analog signal conditioning.

For engineers reviewing the STM32G071G8U6N datasheet, STM32G071G8U6N pinout, STM32G071G8U6N application, or STM32G071G8U6N equivalent, key selection criteria include its 28-pin UFQFPN footprint, 1.7–3.6 V supply range, 14-timer peripheral set (including two 128 MHz-capable advanced timers), RTC with periodic wakeup from Stop/Standby, and dual DAC + comparator analog subsystem for closed-loop control.

Technical Context

The STM32G071G8U6N implements an Arm Cortex-M0+ core with MPU, supporting TrustZone-like memory protection via securable flash area and readout protection levels. Its clock system integrates 4–48 MHz HSE, 32 kHz LSE with calibration, and ±1% internal 16 MHz RC oscillator with PLL - enabling precise timing for USB PD negotiation and real-time motor control loops.

Peripheral interconnect uses a multi-layer AHB/APB bus matrix with DMAMUX routing, allowing flexible DMA mapping across 7-channel controller. Analog subsystem includes rail-to-rail comparators with programmable inputs, temperature sensor, VREFINT, and VBAT monitoring - all accessible during low-power Stop/Standby modes with sub-μA retention current.

FAQ

What is the maximum operating frequency and voltage range of the STM32G071G8U6N?

The STM32G071G8U6N operates at up to 64 MHz with a supply voltage range of 1.7 V to 3.6 V. Its internal 16 MHz RC oscillator has ±1% accuracy and can feed the PLL to achieve full CPU speed. Voltage regulation includes programmable brownout reset (BOR) and voltage detector (PVD) thresholds, ensuring reliable operation across battery discharge curves and noisy industrial rails.

Does the STM32G071G8U6N support USB-C Power Delivery without external components?

Yes - it integrates a complete USB Type-C Power Delivery controller, including PHY, protocol engine, and BMC coding/decoding logic. It supports Source/Sink roles, PD 3.0 message handling, and VCONN switching. No external PD controller IC or level shifters are needed; only passive magnetics and USB-C connector are required for full PD implementation.

How many analog-to-digital converter channels does this MCU support, and what is its effective resolution?

The STM32G071G8U6N features a single 12-bit ADC with up to 16 external input channels and hardware oversampling capability. With 16× oversampling, it achieves up to 16-bit effective resolution (ENOB ≈ 14.2 bits per DS12232 Rev 5 Table 60). Conversion time is 0.4 µs at 12-bit, and the ADC operates down to 1.62 V supply, maintaining linearity across the full 0–3.6 V input range.

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

The MCU supports Sleep, Stop, Standby, and Shutdown modes. In Standby mode with RTC and backup registers active, typical current consumption is 0.32 µA at 25°C (DS12232 Rev 5 Table 30). Wakeup sources include EXTI lines, RTC alarm, LPUART, and I²C address match - enabling ultra-low-power sensor polling every 10 seconds while retaining timekeeping and critical state.
