STM32H750IBK6 Présentation
An Arm Cortex-M7 microcontroller is a 32-bit RISC processor core with superscalar pipeline, hardware Floating-Point Unit (FPU), and tightly-coupled memory (TCM) interfaces, designed for deterministic real-time performance at high clock rates. The Cortex-M7 occupies the high-performance tier of the Cortex-M family (Cortex-M0/M0+/M3/M4/M7/M33), sitting above the Cortex-M4 in DSP performance and below the Cortex-M85 in application-class workloads. It is widely used in industrial motor control, audio processing, graphics HMIs, and high-speed IoT edge nodes, where it is hierarchically classified as: microcontroller -> embedded MCU -> 32-bit RISC MCU -> Arm-based MCU -> STM32 family -> STM32H7 series -> STM32H750 value line.
Key features of the STM32H750IBK6 include 480 MHz CPU speed with 1027 DMIPS / 2854 CoreMark performance, dual-octal SPI interfaces, three ADC units up to 3.6 MSPS, two 12-bit DACs, multiple CAN-FD, USB OTG (FS+HS), Ethernet, and SDMMC peripherals. The 1 MB of internal SRAM is partitioned into DTCM, AXI SRAM and Backup SRAM domains to support the dual-bus matrix that the Cortex-M7 requires for parallel instruction and data fetches.
The 176+25 UFBGA package exposes the full STM32H7 peripheral set: 35 communication interfaces, up to 168 GPIO, and 4 KB of battery-domain backup registers. The 128 KB Flash makes this the value-line sibling of the STM32H743/H753 - designers using external Quad-SPI or FMC memory can keep the application in 128 KB and back it with execute-in-place (XiP) external Flash for code and a dedicated SDRAM bank for data.
Typical applications for the STM32H750IBK6 include industrial drives and motor control (FOC, PFC), high-end audio processing and consumer audio, human-machine interface (HMI) panels, point-of-sale terminals, machine-vision edge nodes, and high-speed IoT gateways. The 480 MHz core, hardware JPEG codec, and large SRAM make it especially attractive for camera-based systems and graphics-rich GUIs rendered on TFT LCDs.
When designing with this part, note that the value-line 128 KB Flash requires most firmware to be executed from external memory (XiP over OSPI/FMC); the internal Flash is typically used for the boot loader, secure firmware update, and key storage. The UFBGA 176+25 footprint also requires careful PCB layout with microvia fan-out and matched-length traces on the parallel memory bus.

Applications typiques
STM32H750IBK6 convient pour 6 applications: Industrial Motor Control (FOC / PFC), High-End Audio Processing / Consumer Audio, Graphics HMI Panels (TouchGFX TFT LCDs), Point-of-Sale / Payment Terminals, Industrial IoT Edge Gateways, Drones / UAV Flight Controllers.
Industrial Motor Control (FOC / PFC)
The STM32H750IBK6's 480 MHz Cortex-M7 with single-precision FPU and DSP extensions is well matched to field-oriented control (FOC) loops for PMSM and induction motors, executing Clarke/Park transforms and SVPWM in single-digit microseconds. The three 16-bit ADCs (3.6 MSPS) sample two current shunts and the BEMF voltage simultaneously with sub-microsecond jitter, while the HRTIM peripheral produces center-aligned PWM with 100 ps resolution for 200 kHz+ switching frequencies. The 1 MB SRAM holds controller state plus a slow control loop, and the hardware crypto block secures the field firmware. The UFBGA 176+25 footprint exposes the full timer set needed for dual-axis FOC plus PFC.

High-End Audio Processing / Consumer Audio
The STM32H750IBK6's 480 MHz core, double-precision FPU and large 1 MB SRAM make it an excellent platform for multi-channel audio processing, S/PDIF bridging, USB audio class 2.0 devices, and software-defined effects. The SAI and SPDIFRX peripherals interface to external codecs, while the USB OTG High-Speed controller supports 480 Mbps isochronous USB audio. The Cortex-M7 SIMD instructions accelerate biquad and FIR filter chains, leaving headroom for graphic EQ displays on a TFT. The hardware JPEG codec is a bonus for products that combine audio with album-art display. Volume production at $9.65 / 1k units keeps the BOM in range for mid-priced consumer audio gear.

Graphics HMI Panels (TouchGFX TFT LCDs)
The STM32H750IBK6 drives WQVGA/QVGA TFT LCDs directly through the integrated LTDC interface and the Chrom-ART (DMA2D) accelerator, with the 1 MB SRAM hosting double-buffered framebuffers and a 16-bit SDRAM (when FMC is used) for larger panels. TouchGFX designer tooling produces optimized C++ UIs that the 480 MHz core can render at 60 fps even with alpha-blended widgets and animations. The hardware JPEG decoder accelerates loading of image assets, while the SDMMC and OSPI controllers fetch them from external Flash. The UFBGA 176+25 footprint gives the full 24-bit RGB LCD interface plus the capacitive touch I2C/IO bus.
Recommandé
Point-of-Sale / Payment Terminals
The STM32H750IBK6's hardware crypto (AES-256, SHA-256 Hash, TRNG) is essential for PCI PTS 5.x and EMVCo L1 compliance in payment terminals, while the 480 MHz core and 1 MB SRAM run the secure RTOS plus the user-facing UI without external memory. The USB OTG High-Speed and Ethernet peripherals connect to the gateway, the SDMMC supports encrypted card storage, and the OSPI interface can be paired with a secure element. The 128 KB internal Flash hosts the secure boot loader and immutable root-of-trust, with the rest of the firmware executed in encrypted XiP from external memory.

Industrial IoT Edge Gateways
The STM32H750IBK6 is a strong fit for industrial IoT edge gateways that aggregate multiple fieldbuses (CAN-FD, RS-485, UART) and bridge them to Ethernet or Wi-Fi. The Cortex-M7 @ 480 MHz plus 1 MB SRAM run a TCP/IP stack (LwIP), an MQTT-SN client, and on-edge data preprocessing/filtering with no external SDRAM needed. The dual CAN-FD controllers interface to automotive/industrial CAN, the SDMMC to local storage, and the OSPI to a Wi-Fi 6 module or LTE modem. AES-256 and TRNG accelerate TLS handshake and OTA firmware update verification.
Recommandé
Drones / UAV Flight Controllers
The STM32H750IBK6's 480 MHz Cortex-M7 with FPU executes Betaflight/ArduPilot attitude and position loops at 8 kHz with comfortable headroom, and the 1 MB SRAM hosts the sensor fusion state plus the optical-flow or SLAM buffer. Three SPI ports connect to MPU6000/ICM-42688 IMUs, the UARTs to GPS and radio receivers, and the CAN-FD to ESC telemetry. The UFBGA 176+25 footprint exposes the full timer set needed for DSHOT/onewire ESC protocols, and the hardware crypto block secures the link to the ground station. Cost per unit (~$9.65 at 1k) keeps the BOM in hobbyist range.

Notes de conception
Estimated: the UFBGA 176+25 (10x10 mm, 0.65 mm ball pitch) requires a 4-layer PCB minimum with microvia-in-pad fan-out. Matched-length impedance control of +/- 10 mil on the 16-bit FMC bus is essential to keep the SDRAM read window valid at 100 MHz. Use 50-ohm single-ended and 100-ohm differential routing on the USB OTG HS and Ethernet pairs. Decouple every VDD/VSS pair with a 100 nF X7R plus 4.7 uF X5R ceramic placed within 2 mm of the ball. Reference ST application note AN5252 (UFBGA fan-out) and AN4661 (FMC SDRAM layout).
Boot configuration: the BOOT0 pin and the option bytes determine whether the Cortex-M7 boots from internal Flash, system memory (bootloader), or external memory via FMC/OSPI. Because the STM32H750IBK6 has only 128 KB internal Flash, the typical pattern is: internal Flash = secure boot ROM (firmware-update and key-store); firmware body = encrypted external OSPI Flash with execute-in-place (XiP) - reference ST AN5054 (XiP) and AN4960 (OSPI). Forgetting the boot-pin pull-down and OTP lock-bits can leave the device un-recoverable.
Estimated: at 480 MHz with all peripherals enabled, the core current draw is ~250 mA from VDD (1.2 V core). Use a 4.7 uF bulk + 100 nF local decoupling per pair, plus a dedicated LDO (e.g. ST LDO414) or a switching regulator with 2% accuracy. Power-on reset: VDD must rise monotonically and reach 1.62 V within 30 ms or the POR circuit will hold the part in reset. Reference ST AN5419 for power design.
The Cortex-M7 at 480 MHz can pull 1027 DMIPS and reach 2854 CoreMark only if the AXI bus to SRAM (max 200 MHz) does not stall. The 16-bit parallel FMC bus must be length-matched within 25 mm and routed over a continuous ground reference plane. The OSPI hyperbus interface, when used, requires 50-ohm characteristic impedance and source-series termination for reliable DDR operation at 200 MHz. Reference ST AN4960 for OSPI layout guidelines.
