Product details
Overview
STM32G473MCT3TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 512 KB Flash (ECC), 128 KB SRAM (96 KB + 32 KB CCM), and integrated analog peripherals including five 12-bit ADCs (0.25 µs), seven 12-bit DACs, six rail-to-rail op-amps, and CORDIC/FMAC math accelerators - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G473MCT3TR datasheet, STM32G473MCT3TR pinout, STM32G473MCT3TR application, or STM32G473MCT3TR equivalent, key selection criteria include its 170 MHz CPU frequency, dual-bank Flash with read-while-write capability, 5 V-tolerant I/Os, FDCAN support, and UCPD interface for USB Type-C™ power delivery control.
Technical Context
The STM32G473MCT3TR implements an Arm Cortex-M4 core with hardware FPU and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at up to 170 MHz (213 DMIPS). It integrates a multi-AHB interconnect matrix for concurrent peripheral access and supports dual-bank Flash programming with PCROP for secure firmware updates.
Its analog subsystem includes three buffered 1 MSPS DAC outputs, four unbuffered 15 MSPS internal DAC channels, seven ultra-fast comparators, and six op-amps configurable in PGA mode - all supported by dedicated voltage reference buffer (VREFBUF) with selectable 2.048 V / 2.5 V / 2.9 V outputs and hardware parity on critical SRAM blocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G431KBT6 | Same Cortex-M4 core but 128 KB Flash, no CORDIC/FMAC, fewer ADC/DAC channels, 32-pin LQFP package. | Suitable for cost-sensitive motor gate drivers or basic digital power controllers without complex math acceleration. | Select when Flash size, analog channel count, and math accelerator features are non-critical and board space allows larger LQFP footprint. |
| STM32H743VIT6 | Cortex-M7 core, 2000 DMIPS, 2 MB Flash, dual-core architecture, no integrated UCPD or CORDIC, larger 100-pin LQFP package. | Targeted at high-end HMI, AI edge inference, or multi-protocol gateway applications requiring higher throughput than motor control. | Choose only if raw performance and memory capacity outweigh need for USB-C PD integration and analog-rich feature set of G4 series. |
Compared with STM32G431KBT6, the STM32G473MCT3TR adds math acceleration and richer analog resources for demanding real-time control; versus STM32H743VIT6, it trades peak CPU performance for superior analog integration, lower power, and native USB-C PD support in a smaller 48-pin form factor.

FAQ
What is the operating temperature range for STM32G473MCT3TR?
The STM32G473MCT3TR is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 5.3.1 of the DS12712 Rev 5 datasheet, which specifies ambient operating conditions and thermal derating curves for the UFQFPN48 package under defined power dissipation limits.
Does STM32G473MCT3TR support hardware encryption or secure boot?
No, the STM32G473MCT3TR does not include hardware cryptographic accelerators (AES, PKA) or secure boot ROM. It supports software-based security via proprietary code readout protection (PCROP), securable memory areas, and 96-bit unique ID - but lacks TRNG-based key generation or tamper detection found in STM32G474/G484 variants.
Can STM32G473MCT3TR replace STM32F303RCT6 in existing designs?
Pin compatibility is not guaranteed: STM32G473MCT3TR (UFQFPN48) and STM32F303RCT6 (LQFP64) differ in package, pin count, and peripheral mapping. While both offer Cortex-M4 cores and analog features, G473 adds CORDIC/FMAC, UCPD, and FDCAN - requiring PCB and firmware redesign for migration.
What debug interfaces are supported by STM32G473MCT3TR?
The device supports Serial Wire Debug (SWD) and JTAG via dedicated SWCLK/SWDIO and TCK/TMS/TDO/TDI pins. Embedded Trace Macrocell (ETM) is included for instruction trace, and SWV (Serial Wire Viewer) enables real-time printf debugging - all documented in Section 3.39 of the DS12712 datasheet.
