Product details
Overview
STM32G473VEH6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU and ART Accelerator, delivering 170 MHz/213 DMIPS performance, 512 KB Flash with ECC, 128 KB SRAM (96 KB + 32 KB CCM), and integrated analog peripherals including 5×12-bit ADCs (0.25 µs), 7×DAC channels, 6×OPAMPs, and CORDIC/FMAC math accelerators - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G473VEH6TR datasheet, STM32G473VEH6TR pinout, STM32G473VEH6TR application, or STM32G473VEH6TR equivalent, key selection criteria include its dual-bank Flash with PCROP, 32-bit advanced timers with dead-time control, FDCAN support for automotive-grade communication, and VREFBUF with selectable 2.048 V / 2.5 V / 2.9 V outputs for precision analog subsystems.
Technical Context
The STM32G473VEH6TR implements an Arm Cortex-M4 core with hardware FPU and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its memory architecture includes two independent Flash banks supporting read-while-write and secure code protection (PCROP), plus 96 KB SRAM with parity on first 32 KB and 32 KB CCM-SRAM with parity on instruction/data bus.
Analog integration centers on five 12-bit ADCs (up to 42 channels, 0.25 µs conversion), seven 12-bit DACs (3 buffered external @ 1 MSPS, 4 unbuffered internal @ 15 MSPS), six rail-to-rail OPAMPs configurable as PGAs, and dedicated hardware accelerators: CORDIC for trigonometric computation and FMAC for FIR/IIR filtering - all synchronized via a multi-AHB interconnect matrix.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G474RET6 | Same core/peripherals but 512 KB Flash, 256 KB SRAM (128 KB + 128 KB CCM); no VREFBUF; different pinout | Better suited for memory-intensive firmware with large buffers or OTA update partitions | Select when CCM-SRAM >32 KB is required and VREFBUF is not needed for analog subsystems |
| STM32F303VET6 | Cortex-M4F @ 72 MHz, 512 KB Flash, 80 KB SRAM; no CORDIC/FMAC; only 3×ADC, 2×DAC, 4×OPAMP | Limited math acceleration and analog density; lacks FDCAN and UCPD | Choose for cost-sensitive, lower-performance motor control where USB-C or CAN FD are unnecessary |
Compared with STM32G473VEH6TR, the STM32G474RET6 trades VREFBUF and pin compatibility for doubled CCM-SRAM - beneficial for complex control algorithms - while the STM32F303VET6 offers legacy toolchain continuity at reduced analog/math capability and no USB-C/Power Delivery support.

FAQ
What is the operating temperature range for STM32G473VEH6TR?
The STM32G473VEH6TR is rated for industrial temperature operation from –40 °C to +85 °C ambient, validated per STMicroelectronics' qualified process and documented in Section 5.3.1 of DS12712 Rev 5. Thermal derating begins above 85 °C ambient, and junction temperature must remain ≤125 °C under all operating conditions.
Does STM32G473VEH6TR support USB Type-C™ Power Delivery negotiation?
Yes - it integrates a dedicated USB Type-C™ and Power Delivery (UCPD) controller compliant with USB PD 3.0 specification. The UCPD peripheral handles BMC physical layer signaling, policy engine execution, and VCONN switching without external components, enabling source/sink/host role implementation in compact USB-C designs.
How many ADC channels can be simultaneously sampled with hardware synchronization?
The STM32G473VEH6TR supports simultaneous sampling across up to 5 independent 12-bit ADCs using hardware trigger synchronization via TIMx TRGO or external event. Each ADC supports up to 42 channels (with multiplexing), and combined throughput reaches 5 MSps when oversampling is disabled - confirmed in Section 3.18 of DS12712.
Is the Flash memory protected against unauthorized readout?
Yes - the device implements Proprietary Code Readout Protection (PCROP) allowing selective write-protection and read-protection of Flash sectors, plus standard RDP (Readout Protection) levels. PCROP enables secure firmware IP protection while permitting field updates to unprotected regions, as detailed in Section 3.4 and RM0440 reference manual.
