Product details
Overview
STM32H735VGT6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit MCU operating at up to 550 MHz, featuring 1 MB flash with ECC, 564 KB SRAM (all with ECC), dual 16-bit ADCs (3.6 MSPS), triple FD-CAN interfaces, Ethernet MAC, USB 2.0 HS/FS OTG, and hardware crypto acceleration (AES-128/192/256, SHA-2, HMAC). It targets real-time industrial HMI, motor control gateways, and secure edge nodes requiring deterministic processing and rich peripheral integration.
For engineers reviewing the STM32H735VGT6 datasheet, STM32H735VGT6 pinout, STM32H735VGT6 application, or STM32H735VGT6 equivalent, key selection considerations include its 550 MHz M7 core with L1 cache, triple FD-CAN for automotive diagnostics, integrated Chrom-ART accelerator for XGA LCD-TFT rendering, and on-the-fly Octo-SPI decryption for secure firmware execution.
Technical Context
The STM32H735VGT6 implements a dual-bank Arm Cortex-M7 core with DP-FPU, 32 KB instruction and 32 KB data caches enabling zero-wait-state execution from flash or external memory. Its memory subsystem includes 128 KB TCM RAM for time-critical code/data and 432 KB system RAM - configurable to remap up to 256 KB as instruction TCM - all protected by ECC.
Peripherally, it integrates three FD-CAN controllers compliant with ISO 11898-1:2015, supporting both Classic CAN and CAN FD frames up to 5 Mbps; an Ethernet MAC with DMA; two SAI audio interfaces; and dedicated accelerators for CORDIC (trigonometric) and FMAC (filtering) operations - reducing CPU load in signal processing and motion control applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VIT6 | Higher flash (2 MB) and RAM (1 MB), adds DSI host, no Ethernet MAC, same FD-CAN count | Better suited for display-centric applications without wired networking; lacks integrated PHY for Ethernet | Select when display bandwidth > connectivity bandwidth; avoid if Ethernet MAC + DMA is required |
| STM32H753VIT6 | Same memory and peripherals as H743 but adds AES-256, SHA-256, and secure firmware update (SB-SFU) enhancements | Targeted at certified security applications (e.g., IEC 62443 Level 2); higher BOM cost due to extended crypto features | Select when FIPS 140-2 or PSA Certified Level 2 compliance is mandated; otherwise H735 offers optimal cost/performance balance |
Compared with STM32H743VIT6, the STM32H735VGT6 trades display bandwidth (no DSI) for integrated Ethernet MAC and lower cost - making it superior for industrial gateways. Against STM32H753VIT6, it omits advanced crypto certifications but delivers identical real-time performance at reduced unit price for non-certified deployments.
