Product details
Overview
STM32H7R3V8H6 from STMicroelectronics is an Arm® Cortex®-M7 32-bit microcontroller operating at up to 600 MHz, featuring 64 KB flash, 620 KB SRAM (548 KB with ECC), dual FD-CAN, Ethernet MAC, and hardware JPEG codec. It integrates NeoChrom GPU2D and Chrom-ART Accelerator for advanced graphics in industrial HMI and edge AI vision systems.
For engineers reviewing the STM32H7R3V8H6 datasheet, STM32H7R3V8H6 pinout, STM32H7R3V8H6 application, or STM32H7R3V8H6 equivalent, key selection criteria include FD-CAN timing compliance, TCM RAM allocation for real-time control loops, octo-SPI XiP support for external code execution, and secure boot via embedded Root Secure Services (RSS).
Technical Context
The device implements a dual-bank Arm Cortex-M7 core with 32+32 KB L1 instruction/data cache, enabling zero-wait-state execution from flash or external memory. Its bus-interconnect matrix supports concurrent AXI/AHB/APB access with 2x dual-port DMA controllers for offloading high-bandwidth peripherals like Ethernet and SAI.
Security architecture includes certificate-based debug authentication, secure hide protection area (HDP), and Public Key Accelerator (PKA) supporting only ECC verification - not full asymmetric crypto acceleration. Graphics subsystem combines NeoChrom GPU2D (rotation/scaling), Chrom-GRC (GFXMMU for 20% resource optimization), and LCD-TFT controller supporting XGA resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M7 @ 600 MHz with DP-FPU, MPU, and 32+32 KB L1 cache - enables deterministic real-time execution and floating-point-intensive motor control algorithms. |
| Memory | 64 KB user flash + 620 KB SRAM (64+64 KB TCM, 384 KB AXI, 4 KB backup) - supports time-critical ISR placement in TCM and large frame buffers in AXI SRAM. |
| Graphics IP | NeoChrom GPU2D + Chrom-ART Accelerator (DMA2D) + Chrom-GRC (GFXMMU) - accelerates UI rendering, texture mapping, and reduces GPU memory bandwidth by up to 20%. |
| Connectivity | 2× FD-CAN, 1× Ethernet MAC with DMA, 2× USB OTG (FS/HS), 1× UCPD - meets automotive diagnostics (ISO 11898-1:2015) and industrial time-sensitive networking requirements. |
| Analog & Timing | 2× 12-bit ADC @ 5 MSPS (17 ch), CORDIC co-processor, RTC with sub-second calendar - supports multi-axis sensor fusion and precise timestamping for predictive maintenance. |
| Security | Secure firmware installation (SFI/SFU), 96-bit unique ID, 1 KB OTP, HASH/RNG/NIST SP800-90B TRNG, active tampers - satisfies IEC 62443-3-3 SL2 for secure OTA updates. |
| Power Management | SMPS step-down converter + LDO + POR/PVD/BOR - achieves 120 µA/MHz active power and supports dynamic voltage scaling across Stop/Standby modes. |
Pinout & Package
STM32H7R3V8H6 is housed in a VFQFPN68 (10 × 10 mm) package with 68 pins, optimized for compact industrial control modules and space-constrained edge AI gateways. Pin count and layout align with ST's standardized H7R series footprint compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Core & I/O power supply | Separate 1.71–3.6 V domains enable independent noise filtering and low-power domain isolation. |
| VCAP | Core regulator decoupling | Requires external 2.2 µF ceramic capacitor per VCAP pin to stabilize SMPS/LDO output for CPU voltage rail. |
| NRST | Active-low reset input | Asynchronous reset with internal pull-up; compatible with external watchdog or power supervisor assertion. |
| BOOT0 | Boot mode selection | Pulled low by default; high during reset forces system memory boot for ISP or recovery without debugger. |
| PA13/PA14 | SWD debug interface | Shared with GPIO; enables authenticated debug access only after lifecycle state permits (e.g., "Secure" or "Production" mode). |
| PD0/PD1 | OSC_IN/OSC_OUT | Supports 4–50 MHz external crystal for precise clock source; required for USB/Ethernet PLL stability and jitter-sensitive CAN FD timing. |
Key Features
| Feature | Design Value |
|---|---|
| Secure Boot with RSS | Root Secure Services enforce authenticated image validation using SHA-256 and ECC signature before execution - prevents unauthorized firmware injection. |
| FD-CAN with ISO 11898-1:2015 | Two fully independent FD-CAN controllers support data rates up to 5 Mbps and flexible bit timing for legacy CAN and high-speed diagnostics. |
| Octo-SPI with XiP | Single octo-SPI interface enables eXecute-in-Place from HyperFlash™ or serial PSRAM at up to 200 MHz - eliminates boot ROM dependency and reduces BOM cost. |
| Hardware JPEG Codec | Dedicated encoder/decoder processes YUV422/JPEG streams at up to 60 fps (VGA) - offloads CPU for smart camera preprocessing without external ASIC. |
| Low-Power Timers (LPTIM) | Five 16-bit LPTIMs retain operation in Stop mode with sub-millisecond wake-up latency - ideal for periodic sensor sampling in battery-powered edge nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VI | Higher flash (2 MB vs. 64 KB), no integrated SMPS, larger LQFP100 package (100 pins), lacks secure boot RSS and PKA. | Targeted at general-purpose HMI with external power ICs and less stringent security requirements. | Select when needing larger code space and legacy toolchain support, but accept higher BoM cost and reduced security certification readiness. |
| STM32H753VI | Same package and pinout, 2 MB flash, 1 MB SRAM, adds cryptographic accelerators (AES-GCM, SHA-2, PKA full), no JPEG codec or NeoChrom GPU. | Suitable for secure IoT concentrators requiring TLS offload but no local graphics processing. | Choose for TLS-heavy applications where hardware crypto throughput outweighs graphics acceleration needs - avoids JPEG licensing overhead. |
Compared with STM32H7R3V8H6, STM32H743VI trades security and power integration for raw memory capacity, while STM32H753VI enhances crypto capability at the expense of graphics IP - making the H7R3 optimal for cost-sensitive, graphics- and security-aware edge devices.

FAQ
What is the maximum operating frequency and supported voltage range?
The STM32H7R3V8H6 operates at up to 600 MHz with a core supply range of 1.71 V to 3.6 V. Its integrated SMPS and LDO regulators allow direct connection to 3.3 V or 5 V input rails, with VCAP decoupling critical for stable high-frequency operation. Electrical characteristics confirm 600 MHz functionality across the full temperature range (–40°C to +125°C) under specified VDD conditions.
Does this MCU support secure firmware updates over-the-air?
Yes - it implements Secure Firmware Installation/Update (SFI/SFU) via embedded Root Secure Services (RSS), which validate signed firmware images using SHA-256 hashing and ECC-256 signatures before execution. The 1 KB OTP stores root keys, and the secure hide protection area (HDP) isolates sensitive assets from runtime access.
How many FD-CAN interfaces does STM32H7R3V8H6 provide, and what standards do they meet?
The device integrates two fully independent FD-CAN controllers compliant with ISO 11898-1:2015, supporting both Classical CAN and CAN FD data rates up to 5 Mbps. Each controller features dedicated message RAM, flexible bit timing, and hardware loopback for self-test - validated in ST's AN5027 application note for automotive diagnostics.
Is hardware JPEG encoding/decoding supported, and what resolutions are achievable?
Yes - the dedicated hardware JPEG codec supports baseline sequential encoding and decoding of YUV422/JPEG streams. At VGA resolution (640×480), it achieves up to 60 fps encoding and 120 fps decoding; at QVGA (320×240), throughput scales to 240 fps decode - all without CPU intervention, as confirmed in Section 3.29 of DS14360 Rev 6.
