Product details
Overview
STM32F745VEH6 from STMicroelectronics is a high-performance ARM Cortex-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 512 KB flash memory, 320 KB SRAM (including 64 KB data TCM and 16 KB instruction TCM), USB OTG HS/FS, 10/100 Ethernet MAC, LCD-TFT controller, and dual CAN 2.0B interfaces - deployed in industrial HMI, medical imaging front-ends, and real-time motor control systems.
For engineers reviewing the STM32F745VEH6 datasheet, STM32F745VEH6 pinout, STM32F745VEH6 application, or STM32F745VEH6 equivalent, key selection considerations include TCM RAM allocation for deterministic ISR latency, dual-CAN timing synchronization capability, Ethernet IEEE 1588v2 hardware timestamping, and Chrom-ART Accelerator™ support for GUI rendering offload.
Technical Context
The STM32F745VEH6 implements an Arm Cortex-M7 core with tightly coupled memory (TCM) architecture: 64 KB data TCM enables zero-wait-state access for time-critical buffers, while 16 KB instruction TCM hosts real-time control routines. Its ART Accelerator™ and 4 KB instruction/data caches eliminate flash wait states across full 216 MHz operation.
Peripherals are interconnected via AXI/AHB bus matrix supporting concurrent high-bandwidth transfers: Ethernet MAC DMA, DCMI camera interface (54 MB/s), and dual SAI audio controllers operate independently without CPU intervention, enabling simultaneous vision, networking, and audio processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M7 with FPU, 216 MHz max frequency - enables floating-point intensive algorithms (e.g., sensor fusion, FFT-based analysis) without external coprocessor. |
| Flash Memory | 512 KB embedded Flash - sufficient for dual-bank firmware updates and secure boot partitioning with hardware write protection. |
| SRAM | 320 KB total: 64 KB data TCM + 16 KB instruction TCM + 4 KB backup SRAM - TCM ensures deterministic interrupt response; backup SRAM retains data in Standby mode with VBAT. |
| ADC | Three 12-bit ADCs, up to 24 channels, 7.2 MSPS in triple interleaved mode - supports synchronized sampling of multi-axis motor current/voltage feedback. |
| Ethernet | 10/100 MAC with dedicated DMA and IEEE 1588v2 hardware timestamping - enables precise time-synchronized industrial control over standard Ethernet infrastructure. |
| Display Interface | LCD-TFT controller up to XGA (1024×768) with Chrom-ART Accelerator™ (DMA2D) - accelerates 2D graphics operations (copy, fill, blend) freeing CPU for application logic. |
| Camera Interface | 8–14-bit parallel DCMI supporting 54 MB/s throughput - interfaces directly with CMOS image sensors for real-time video capture without frame buffer bottlenecks. |
Pinout & Package
LQFP100 (14 × 14 mm, 0.5 mm pitch) package with 100 leads; thermally enhanced exposed pad (EPAD) for improved power dissipation in sustained 216 MHz operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDIO2 | Core, analog, and I/O supply rails | Separate 1.7–3.6 V domains enable noise isolation between digital logic, ADC reference, and 5 V-tolerant GPIOs. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O ports | 168 total I/Os; up to 166 are 5 V-tolerant - simplifies level-shifting in mixed-voltage industrial backplanes. |
| PH13–PH15, PI0–PI10 | DCMI data bus (D0–D13) | Dedicated 14-bit parallel camera input pins with programmable polarity and synchronization (HS/VSYNC) - supports raw Bayer or YUV streaming. |
| PE2–PE7, PF10–PF15 | LCD-TFT RGB interface (R0–R7, G0–G7, B0–B7) | 24-bit parallel RGB output with HSYNC/VSYNC/DE signals - drives TFT panels directly without external timing controller. |
| PA12/PA11, PB14/PB15 | USB OTG HS ULPI & FS PHY | Dual-phy support: full-speed internal PHY + high-speed ULPI interface - enables simultaneous device/host roles and USB 2.0 HS peripheral attachment. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive Real-Time Accelerator (ART) | Eliminates flash wait states at 216 MHz, enabling deterministic code execution from embedded Flash without SRAM shadowing. |
| Chrom-ART Accelerator™ (DMA2D) | Hardware-accelerated 2D graphics engine performing memory copy, alpha blending, and color format conversion - reduces CPU load by >70% in GUI-intensive HMIs. |
| Dual CAN 2.0B controllers | Independent message RAMs and filtering units allow synchronized multi-bus communication for distributed control networks (e.g., automotive body domain, factory automation). |
| Flexible Memory Controller (FMC) | Supports NOR, PSRAM, SDRAM, and NAND with ECC - enables external program execution or large framebuffer storage beyond on-chip SRAM limits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F746VET6 | Same core/peripherals but includes embedded Chrom-ART Accelerator™-enabled LCD-TFT controller with RGB interface and MIPI DSI option - adds 128 KB additional Flash (1 MB vs 512 KB). | Required for designs needing MIPI DSI output or larger firmware image storage; not drop-in due to different pinout for DSI lanes. | Select when MIPI DSI panel integration or dual-bank OTA updates are mandatory; verify PCB layout compatibility for DSI signal routing. |
| STM32H743VIT6 | Higher-tier Cortex-M7 @ 480 MHz, dual-core option (M7+M4), 2 MB Flash, 1 MB SRAM, enhanced crypto (AES-256, PKA), no DCMI - lacks parallel camera interface. | Suitable for security-critical edge AI inference or complex protocol stacks (e.g., OPC UA over TLS); unsuitable for direct CMOS sensor interfacing. | Choose for compute-bound applications requiring cryptographic acceleration or heterogeneous processing; avoid if DCMI or legacy parallel display is required. |
Compared with STM32F745VEH6, the STM32F746VET6 extends display capabilities and firmware headroom at the cost of pin compatibility, while the STM32H743VIT6 trades camera interface for raw performance and security - making the F745VEH6 optimal for cost-sensitive, vision-enabled industrial controllers where DCMI and LQFP100 footprint are design constraints.

FAQ
What is the maximum operating temperature range for STM32F745VEH6?
The STM32F745VEH6 is rated for industrial temperature range: –40 °C to +85 °C ambient. Thermal derating begins above 70 °C ambient when operating continuously at 216 MHz; junction temperature must remain below 125 °C, requiring appropriate PCB copper pour and optional heat slug under the EPAD.
Does STM32F745VEH6 support hardware encryption acceleration?
No - the STM32F745VEH6 does not integrate dedicated cryptographic accelerators (e.g., AES, SHA, PKA). It relies on software libraries (STM32Cube Cryptographic Library) or external secure elements. For hardware crypto, consider STM32H743 or STM32L5 series devices.
Can the LCD-TFT controller drive RGB panels without external components?
Yes - the integrated LCD-TFT controller supports direct 24-bit RGB interface (R0–R7, G0–G7, B0–B7) with HSYNC, VSYNC, and DE signals. No external timing controller is needed for XGA (1024×768) or lower-resolution panels; only passive termination resistors and proper impedance-controlled routing are required.
How many independent CAN buses does STM32F745VEH6 support?
The STM32F745VEH6 integrates two fully independent bxCAN 2.0B controllers, each with its own message RAM, filter banks, and clock domain. They operate simultaneously without resource contention, enabling dual-bus architectures such as CANopen master/slave and J1939 diagnostics channel separation.
