Product details
Overview
STM32G071C8U6TR from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 64 MHz max CPU frequency, 128 KB flash, and 36 KB SRAM, operating from 1.7–3.6 V across –40°C to 85°C. It integrates dual 12-bit DACs, a 12-bit 0.4 µs ADC (16-channel), four USARTs (two with ISO7816/LIN/IrDA), two I²C interfaces (one Fast-mode Plus), two SPIs (32 Mbit/s), USB Type-C™ Power Delivery controller, and calendar RTC - deployed in smart metering, industrial sensor nodes, and battery-powered HMI control panels.
For engineers reviewing the STM32G071C8U6TR datasheet, STM32G071C8U6TR pinout, STM32G071C8U6TR application, or STM32G071C8U6TR equivalent, key selection criteria include its 48-pin UFQFPN package, 60 fast I/Os (multiple 5 V-tolerant), low-power Stop/Standby modes (down to 190 nA in Shutdown), and integrated USB PD controller for source-sink negotiation in compact power adapters and portable chargers.
Technical Context
The device implements a single-core Arm Cortex-M0+ 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 internal 16 MHz RC (±1 %) with PLL - enabling precise timing for real-time motor control and communication stacks.
Peripheral interconnect uses dedicated DMA request multiplexer (DMAMUX) and flexible GPIO remapping, allowing concurrent operation of high-speed SPI, UART-based LIN, and ADC-triggered DAC output without CPU intervention - critical for deterministic sensor fusion and closed-loop actuation in cost-sensitive industrial edge nodes.

What is the maximum operating frequency and voltage range of the STM32G071C8U6TR?
The STM32G071C8U6TR operates at up to 64 MHz CPU frequency with a supply voltage range of 1.7 V to 3.6 V. It supports dynamic voltage scaling and includes programmable brownout reset (BOR) and voltage detector (PVD) to ensure reliable operation across industrial temperature ranges (–40°C to 85°C) under varying input conditions.
Does the STM32G071C8U6TR support USB Type-C Power Delivery negotiation?
Yes - it integrates a dedicated USB Type-C Power Delivery controller with hardware support for CC1/CC2 line monitoring, VCONN switching, and PD message parsing. This eliminates the need for external PD PHY ICs and enables full source/sink role negotiation in compact adapters and portable chargers.
How many I/O pins are 5 V-tolerant, and what is their functional significance?
Multiple I/Os - including all pins in groups PA0–PA15, PB0–PB15, and PC0–PC15 - are 5 V-tolerant. This allows direct interfacing with legacy 5 V logic, industrial sensors, optocouplers, and RS-232/RS-485 transceivers without external level shifters, reducing BOM cost and board space in mixed-voltage systems.
What low-power modes are available, and what is the lowest achievable current consumption?
The device supports Sleep, Stop, Standby, and Shutdown modes. In Shutdown mode with RTC active and VBAT supplied, typical current consumption is 190 nA - enabling decade-long operation on coin-cell batteries in wireless sensor transmitters and energy-harvesting applications.
