Product details
Overview
STM32G473VBH6 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 five 12-bit ADCs (0.25 µs), seven 12-bit DACs, six operational amplifiers, and three FDCAN controllers - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G473VBH6 datasheet, STM32G473VBH6 pinout, STM32G473VBH6 application, or STM32G473VBH6 equivalent, key selection criteria include its dual-bank Flash with read-while-write capability, hardware math accelerators (CORDIC + FMAC), 5 V-tolerant I/Os, UCPD interface for USB Type-C™ PD, and ultra-fast rail-to-rail comparators enabling real-time closed-loop control.
Technical Context
The STM32G473VBH6 implements an Arm Cortex-M4 core with floating-point unit and Memory Protection Unit (MPU), supported by the Adaptive Real-Time (ART) Accelerator for zero-wait-state execution from Flash. Its interconnect matrix enables concurrent access to Flash, SRAM, and peripherals without bus contention.
It integrates dedicated hardware accelerators: CORDIC for trigonometric computation and FMAC for FIR/IIR filter execution - both offloading CPU cycles in motor control and signal processing. Clock management includes multiple oscillators (4–48 MHz HSE, 32 kHz LSE with calibration, 16 MHz/32 kHz RC) and three PLLs supporting flexible system clock derivation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4 with FPU and MPU - enables deterministic real-time control with floating-point math and memory isolation. |
| Max Frequency | 170 MHz / 213 DMIPS - supports high-bandwidth control loops and fast data acquisition at sub-microsecond timing resolution. |
| Flash Memory | 512 KB with ECC and dual-bank read-while-write - allows safe firmware updates and secure code storage with error correction. |
| SRAM | 128 KB total: 96 KB general-purpose + 32 KB CCM SRAM with parity - provides low-latency instruction/data caching for critical routines. |
| Analog Peripherals | 5 × 12-bit ADCs (42 ch, 0.25 µs), 7 × 12-bit DACs (3 buffered ext., 4 unbuffered int.), 6 op-amps, 7 comparators - enables full analog front-end integration for sensor conditioning and actuator drive. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G474RET6 | LQFP64 package (64 pins), 512 KB Flash, same core/peripherals but adds AES-256 crypto accelerator and RNG with NIST SP800-90B compliance. | Better suited for secure firmware updates and encrypted communication in IoT gateways. | Select when cryptographic acceleration and certified RNG are required; not pin-compatible with UFQFPN48. |
| STM32F303VCT6 | Older Cortex-M4F (72 MHz), 256 KB Flash, no CORDIC/FMAC, only 1 FDCAN, fewer ADC channels (3 × 12-bit), no UCPD. | Limited to simpler motor control or analog monitoring where math acceleration and USB-C are unnecessary. | Choose for cost-sensitive legacy designs where 170 MHz performance and dual-bank Flash are not needed. |
Compared with STM32G473VBH6, the STM32G474RET6 adds security features at the cost of larger footprint and higher price, while the STM32F303VCT6 sacrifices performance, analog density, and modern interfaces to meet basic control needs - making the G473VBH6 optimal for compact, high-performance digital power and motor control.

FAQ
What is the operating temperature range for STM32G473VBH6?
The STM32G473VBH6 is rated for industrial operation from –40 °C to +85 °C ambient temperature. This range is validated per JEDEC JESD47 and applies to all specified electrical characteristics, including ADC accuracy, oscillator stability, and Flash write endurance. Thermal derating is not required within this envelope.
Does STM32G473VBH6 support hardware encryption?
No, the STM32G473VBH6 does not integrate AES or PKA hardware accelerators. It includes a True Random Number Generator (RNG) and CRC calculation unit, but cryptographic operations must be implemented in software or via external secure elements. For hardware encryption, consider the STM32G474 or STM32L5 series.
Can STM32G473VBH6 run from internal RC oscillators without external crystals?
Yes - it supports startup and full operation using the internal 16 MHz RC oscillator (±1% accuracy with PLL) and 32 kHz RC oscillator (±5%). External crystals are optional for higher timing precision in RTC or communication interfaces, but not required for basic MCU functionality or motor control timing.
What debug interfaces are supported on STM32G473VBH6?
The device supports Serial Wire Debug (SWD) via SWDIO and SWCLK pins, compliant with ARM CoreSight standards. JTAG is also available but shares pins with SWD; SWD is recommended for minimal pin count and full debug capability including breakpoints, watchpoints, and real-time memory access during active execution.
