Overview

STM32G431M6T6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU and ART Accelerator, operating up to 170 MHz (213 DMIPS), featuring 128 KB Flash with ECC, 32 KB SRAM (22 KB + 10 KB CCM), and integrated analog peripherals including dual 12-bit DACs (1 MSPS buffered), dual 12-bit ADCs (0.25 µs, up to 23 channels), 4 comparators, 3 op-amps, and CORDIC/FMAC math accelerators - deployed in motor control, digital power conversion, and industrial sensing systems.

For engineers reviewing the STM32G431M6T6 datasheet, STM32G431M6T6 pinout, STM32G431M6T6 application, or STM32G431M6T6 equivalent, key selection criteria include its 48-pin UFQFPN package, FDCAN support for flexible data-rate automotive/industrial networks, 5 V-tolerant I/Os, hardware RNG, and UCPD interface for USB Type-C™ power delivery implementations.

Technical Context

The STM32G431M6T6 implements an Arm Cortex-M4 core with single-precision FPU and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its memory subsystem includes 128 KB Flash with PCROP and ECC, 22 KB SRAM with parity on first 16 KB, and 10 KB CCM-SRAM with parity - all accessible via multi-AHB interconnect matrix.

Analog integration centers on two independent 12-bit ADCs (23-channel multiplexing, hardware oversampling), four rail-to-rail comparators, three fully accessible op-amps configurable as PGAs, and dual 12-bit DACs - one pair buffered (1 MSPS), one unbuffered (15 MSPS) - supported by internal VREFBUF (2.048 V / 2.5 V / 2.9 V).

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32G431K6T6	LQFP32 package (32-pin), 25 GPIOs, no UCPD, reduced timer count (no TIM8), same core/peripherals otherwise.	Suitable for space-constrained but less feature-dense designs (e.g., basic sensor node without USB-C).	Select when board area is critical and UCPD/FDCAN/advanced timers are unnecessary.
STM32G474RET6	LQFP64 package, 512 KB Flash, 128 KB SRAM, additional ADC/DAC channels, crypto acceleration (AES/RSA), no UCPD.	Targeted at higher-security or higher-fidelity analog applications (e.g., medical-grade power supplies).	Choose when larger code footprint, enhanced security, or extra analog resources justify larger package and cost.

Compared with STM32G431K6T6, the STM32G431M6T6 adds UCPD and FDCAN in a pin-compatible 48-pin footprint; versus STM32G474RET6, it trades Flash/SRAM capacity and crypto for lower cost, smaller size, and USB-C power delivery capability - making it optimal for compact, USB-C–enabled industrial edge devices.

FAQ

What is the maximum operating frequency and associated performance metric of the STM32G431M6T6?

The STM32G431M6T6 operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone MIPS), achieved using the ART Accelerator for zero-wait-state Flash execution. Its Cortex-M4 core includes a single-precision FPU, enabling efficient floating-point math for control algorithms without software emulation overhead.

Does the STM32G431M6T6 support USB Type-C™ Power Delivery, and how is it implemented?

Yes - the STM32G431M6T6 integrates a dedicated USB Type-C™ and Power Delivery (UCPD) controller compliant with USB PD 3.0. It handles physical layer signaling, BMC decoding/encoding, policy engine execution, and VCONN switching, eliminating the need for an external PD controller IC in compact USB-C–enabled designs.

How many analog-to-digital converter (ADC) channels does the STM32G431M6T6 support, and what is their resolution and speed?

The device integrates two independent 12-bit ADCs with up to 23 multiplexed input channels total. Each ADC achieves 0.25 µs conversion time (up to 4 MSPS), supports hardware oversampling up to 16× for effective 16-bit resolution, and operates across the full 0–3.6 V input range with built-in temperature sensor and VREFINT channel.

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

The STM32G431M6T6 offers Sleep, Stop (0/1), Standby, and Shutdown modes. In Standby mode with RTC running and backup registers retained, typical current consumption is 1.3 µA at 25 °C (VDD = 3.3 V). VBAT supply maintains RTC and backup registers during main power loss, with consumption dropping to ~300 nA in VBAT-only mode.
