Product details
Overview
STM32G473VEH6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU and ART Accelerator, operating at up to 170 MHz (213 DMIPS), featuring 512 KB Flash with ECC, 128 KB SRAM (96 KB + 32 KB CCM), and integrated analog peripherals including five 12-bit ADCs (0.25 µs conversion), seven 12-bit DAC channels, six operational amplifiers, and three FDCAN controllers. It targets motor control, digital power conversion, and industrial sensing systems requiring real-time computation and mixed-signal integration.
For engineers reviewing the STM32G473VEH6 datasheet, STM32G473VEH6 pinout, STM32G473VEH6 application, or STM32G473VEH6 equivalent, this page delivers verified technical context, package-specific pin mapping, key analog/digital peripheral specifications, motor-control timer architecture, and validated alternative MCUs for cost, feature, or supply-chain-driven redesigns.
Technical Context
The STM32G473VEH6 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 subsystem includes dual-bank Flash with read-while-write capability, ECC protection, PCROP security, and 96 KB SRAM with parity on first 32 KB plus 32 KB CCM SRAM with parity on instruction/data bus.
Analog integration centers on five independent 12-bit ADCs (up to 42 channels, 0–3.6 V range, hardware oversampling to 16-bit), seven DAC channels (3 buffered external @ 1 MSPS, 4 unbuffered internal @ 15 MSPS), six rail-to-rail op-amps (all terminals accessible, PGA mode supported), and dedicated math accelerators: CORDIC for trigonometric functions and FMAC for filter computations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G431KB6 | Same G4 series, Cortex-M4+FPU, but 128 KB Flash, 32 KB SRAM, no CORDIC/FMAC, 3× FDCAN reduced to 1× | Suitable for cost-sensitive motor control where advanced math acceleration is not required | Select when BOM cost reduction is prioritized over computational headroom and analog channel count |
| STM32F303VCT6 | Cortex-M4+FPU at 72 MHz, 256 KB Flash, 48 KB SRAM, no CORDIC/FMAC, 2× CAN (classic only), 4× 12-bit ADCs | Legacy design continuity for F3-based platforms; lacks FDCAN, UCPD, and advanced analog integration | Choose for migration from F3 where existing firmware reuse and pin compatibility outweigh new feature requirements |
Compared with STM32G473VEH6, the STM32G431KB6 sacrifices math acceleration and peripheral count for lower unit cost, while the STM32F303VCT6 offers proven reliability in legacy designs but lacks FDCAN, UCPD, and the G4's analog density-making it less suitable for next-generation digital power or USB-C–enabled medical devices.

FAQ
What is the maximum operating frequency and associated DMIPS rating of the STM32G473VEH6?
The STM32G473VEH6 operates at a maximum CPU frequency of 170 MHz, delivering 213 DMIPS (Dhrystone MIPS) performance with the ART Accelerator enabled. This benchmark reflects zero-wait-state execution from Flash memory, confirmed in ST's DS12712 Rev 5 datasheet Section 3.1 and Table 17.
Does the STM32G473VEH6 support USB Type-C™ Power Delivery negotiation?
Yes - the STM32G473VEH6 integrates a dedicated USB Type-C™ and Power Delivery (UCPD) controller compliant with USB PD 3.0. It supports source/sink role detection, VCONN switching, and BMC physical layer signaling without external transceivers, as specified in Section 3.35 and electrical characteristics Table 5.3.29 of DS12712 Rev 5.
How many ADC channels does the STM32G473VEH6 support, and what is the highest effective resolution achievable?
The device integrates five independent 12-bit ADCs supporting up to 42 total input channels. With hardware oversampling and decimation, effective resolution reaches 16 bits at reduced sampling rates (e.g., 12-bit @ 2.4 MSPS or 16-bit @ 153 kSPS), per Section 3.18 and Table 5.3.18 in the official datasheet.
What package type and pin count does the STM32G473VEH6 use, and what are its key assembly advantages?
The STM32G473VEH6 uses the UFQFPN48 package: a 7 × 7 mm, 0.5 mm pitch, 48-pin ultra-fine pitch quad flat no-lead with wettable flanks. Its exposed thermal pad improves heat dissipation, while wettable flanks enable reliable automated optical inspection (AOI) of solder joints - critical for high-reliability industrial manufacturing.
