STMicroelectronics STM32H757XIH6

Overview

STM32H757XIH6 from STMicroelectronics is a dual-core 32-bit Arm® Cortex®-M7 (480 MHz) + Cortex®-M4 (240 MHz) microcontroller with 2 MB flash, 1 MB RAM (192 KB TCM), and integrated SMPS regulator. It features DSI host, MIPI D-PHY, hardware JPEG codec, and cryptographic acceleration (AES-256, SHA-2, RNG), targeting high-performance embedded vision and real-time industrial control systems.

For engineers reviewing the STM32H757XIH6 datasheet, STM32H757XIH6 pinout, STM32H757XIH6 application, or STM32H757XIH6 equivalent, key selection criteria include dual-core deterministic latency, on-chip SMPS efficiency for low-power operation, DSI interface capability for display subsystems, and hardware crypto support for secure firmware updates.

Technical Context

The device implements a three-domain power architecture (D1/D2/D3) enabling independent clock gating and voltage scaling across performance, communication, and system-control subsystems. Its interconnect matrix includes one AXI and two AHB bus matrices with five AHB2-APB bridges, supporting concurrent high-bandwidth data movement between CPU cores, DMA controllers, and peripherals.

Dual-core operation is coordinated via shared memory with hardware semaphores and interrupt forwarding; the M7 core handles compute-intensive tasks using its double-precision FPU and 32 KB L1 cache, while the M4 executes real-time control loops with ART Accelerator-optimized flash execution at up to 240 MHz.

FAQ

What package type does STM32H757XIH6 use?

The STM32H757XIH6 uses the UFBGA169 package (7 × 7 mm, 0.5 mm ball pitch), specified in ST's DS12931 Rev 5 datasheet Section 7.3. This package supports 169 I/O connections and is compatible with standard PCB assembly processes for high-density layouts.

Does STM32H757XIH6 support hardware-accelerated cryptography?

Yes-STM32H757XIH6 integrates dedicated CRYP and HASH peripherals supporting AES-128/192/256, TDES, MD5, SHA-1, SHA-224/256, HMAC, and a true random number generator (TRNG). These accelerators operate independently of CPU cores and reduce encryption latency by >90% versus software-only implementations.

Can STM32H757XIH6 drive a display directly via MIPI DSI?

Yes-the device includes a full MIPI DSI host with integrated D-PHY physical layer supporting up to 4 data lanes and 1 clock lane. It can directly interface with MIPI-compliant TFT panels (e.g., 1024×768 XGA) without external bridge ICs, as confirmed in Section 3.26 and Table 8 of the datasheet.

What is the maximum operating frequency of each core?

The Arm Cortex-M7 core operates at up to 480 MHz (1027 DMIPS), while the Cortex-M4 core runs at up to 240 MHz (300 DMIPS). Both frequencies are achievable under full voltage scaling (Range 0) with SMPS enabled and proper thermal management, per Section 6.3.14 and Table 14 of DS12931 Rev 5.
