STM32H730IBK6Q 概要
A microcontroller (MCU) is a single-chip computer that combines a CPU core, memory, and programmable peripherals. Within the broader semiconductor taxonomy, the STM32H730IBK6Q sits at the level of a 32-bit RISC MCU (Cortex-M7 -> ARM Cortex family -> 32-bit MCU -> microcontroller -> semiconductor). It belongs to the high-performance tier of the STM32 family and is designed for applications that demand both DSP capability and real-time control.
Key features include 550 MHz CPU clock, 16 KB I-cache / 16 KB D-cache, 4 KB backup SRAM, an external memory interface (FMC), and an integrated SMPS step-down converter for core supply. The device also provides Ethernet, USB OTG, 3x FDCAN, two 16-bit ADCs, and a graphics subset (Chrom-ART, JPEG codec). The crypto/hash accelerator accelerates AES, SHA, and RSA, allowing secure firmware updates and authenticated communication.
The STM32H730IBK6Q uses a 40 nm CMOS process and a multi-power-domain architecture that allows the SMPS to supply the core directly, reducing external component count. The 564 KB of SRAM is split across DTCM, AXI SRAM, and backup SRAM domains, allowing concurrent DMA and CPU access without contention. Compared to STM32F7 series, the Cortex-M7 core at 550 MHz and 6-stage pipeline provide roughly twice the CoreMark performance.
Typical applications include industrial motor control, factory automation, audio processing with DSP, USB-based peripherals, secure IoT gateways, and human-machine interface (HMI) panels with graphics. The combination of crypto, Ethernet, and FDCAN makes the device suitable for networked industrial controllers and connected medical instruments. The 176-pin UFBGA also supports external SRAM/PSRAM/NOR/NAND via the FMC for applications requiring large buffers.
When designing with this MCU, ensure the SMPS inductor and output capacitors are placed close to the VCAP pins and that the high-speed USB and Ethernet differential pairs are routed with 90-ohm impedance. The crypto accelerator must be clocked from the HSI or HSE source before being used; otherwise the peripheral stays in reset.

主な用途
STM32H730IBK6Q の用途: 6 件s: Industrial Motor Control (FOC), Audio DSP Processing, Secure IoT Gateway, Human-Machine Interface (HMI) Panels, Automotive Body Controller (Sub-system), USB-C Power Delivery Charger.
Industrial Motor Control (FOC)
The STM32H730IBK6Q is a strong fit for industrial motor control because its 550 MHz Cortex-M7 core with DP-FPU executes complex FOC (Field Oriented Control) loops within sub-microsecond intervals. The device integrates 2x 16-bit ADCs at 3.6 MSPS for current sensing, advanced timers for PWM generation, and 564 KB RAM that fits sensorless observers and trajectory planners without external memory. The UFBGA-176 footprint exposes enough pins to drive three-phase inverters for both low-voltage BLDC and high-voltage PMSM motors, while the SMPS simplifies 24V-bus designs.
おすすめ
Audio DSP Processing
The STM32H730IBK6Q's Cortex-M7 DSP extensions and 564 KB RAM make it suitable for multi-channel audio processing at 48 kHz or 96 kHz sample rates. Effects such as EQ, dynamics, mixing, and noise suppression run comfortably with MIPS to spare for USB audio streaming or Bluetooth bridging. The integrated SAI, S/PDIF, and DFSDM peripherals interface directly to common audio codecs. Compared to STM32F4, the H7's six-stage pipeline doubles DSP throughput, enabling more channels or higher-order algorithms at lower power.
おすすめ
Secure IoT Gateway
The STM32H730IBK6Q's hardware crypto/hash accelerator (AES, SHA, RSA, ECDSA) and Ethernet/USB OTG make it an excellent secure IoT gateway MCU. The device can perform TLS handshakes, signed firmware updates, and authenticated MQTT publishes without offloading to a separate secure element. The Cortex-M7 at 550 MHz terminates TLS 1.3 handshakes in tens of milliseconds, and the 564 KB RAM holds TLS context plus TCP/IP stacks (lwIP) plus application logic concurrently. The integrated SMPS simplifies battery-backed designs.
おすすめ
Human-Machine Interface (HMI) Panels
For HMI panels with a color TFT LCD, the STM32H730IBK6Q provides Chrom-ART (2D DMA2D) and a hardware JPEG codec, offloading pixel pushing from the CPU. The 564 KB RAM holds double-buffered framebuffers up to WVGA resolution. The Ethernet and USB OTG support remote HMI management, and the 16-bit ADC simplifies touch-screen sensing. Compared to STM32F769, the H730 has higher RAM density, while sharing the same UFBGA-176 footprint for PCB reuse.
おすすめ
Automotive Body Controller (Sub-system)
Although the STM32H730IBK6Q itself is not AEC-Q100 qualified, it is widely used in automotive sub-systems where the -Q suffix is not required (e.g., bench test equipment, dealer diagnostics). Its 3x FDCAN, Ethernet, and 16-bit ADC are ideal for CAN-FD body domain controllers, gateway prototypes, and ECU development tools. Migration to AEC-Q100 qualified STM32H7 derivatives (e.g., STM32H73xQ) is supported because the peripherals share the same register map.
おすすめ
USB-C Power Delivery Charger
The STM32H730IBK6Q's USB OTG with PD support, 12-bit DACs, and high-resolution timers suit USB-C Power Delivery chargers up to 100 W. The Cortex-M7 handles PD protocol negotiation, source capability messaging, and adaptive over-temperature foldback. The 564 KB RAM holds policy manager and logging, while the SMPS-derived core voltage reduces BOM cost. Compared to STM32F072, the H7 adds crypto for PPS-authenticated chargers.

主な差別化要因
- Single-core Cortex-M7 at 550 MHz with crypto accelerator （vs STM32H735IGK6)
- Lower Flash density vs larger memory siblings （vs STM32H745IGK6)
- Industrial temperature grade (-40 to +85 C) with K6Q suffix （vs STM32H730IBK6)
設計ノート
The STM32H730IBK6Q integrates an SMPS step-down regulator that supplies the core directly from VDD. Place the SMPS inductor (typically 4.7 uH) and the four output capacitors (4x 100 nF + 2x 4.7 uF) as close to the VCAP pins as possible to minimize parasitic inductance. Estimated: total core current at 550 MHz is roughly 80 mA, so the SMPS handles ~240 mW at VDD=3.3 V - well within its 200 mA rating.
Route the 90-ohm differential pairs for USB OTG and Ethernet with controlled impedance, keeping stubs shorter than 2 mm. The 0.65 mm pitch UFBGA-176 requires 4-layer stack-up with micro-via-in-pad for breakout; escape routing on top layer with via stitching to inner ground is recommended. Avoid running noisy SMPS traces adjacent to the 32 kHz LSE crystal pins - keep at least 200 mil separation.
The crypto/hash accelerator must be clocked from HSI or HSE before use - it stays in reset until the clock is configured. Do not exceed 3.6 V on any I/O pin; the SD-card interface is sensitive to bus contention during hot-plug. The OctoSPI interface requires 4-line mode for highest throughput and a 50-ohm series termination on each clock line.
Estimated: at 550 MHz with all caches active and SMPS running, power dissipation is approximately 350 mW - well within the UFBGA-176 thermal envelope (theta_JA ~28 C/W with proper ground pad). For continuous high-throughput DSP workloads, mount thermal vias beneath the exposed pad and connect to inner ground plane.
コンプライアンス情報
K6Q suffix denotes industrial temp grade (-40 to +85 C). For AEC-Q100 automotive grade, use STM32H730Q suffix parts. RoHS/REACH compliance per ST product page.
