STMicroelectronics STM32H730IBK6Q

Overview

STM32H730IBK6Q from STMicroelectronics is an Arm® Cortex®-M7 32-bit microcontroller operating at up to 550 MHz, featuring 128 KB flash with ECC, 564 KB SRAM (all with ECC), dual 16-bit ADCs (up to 3.6 MSPS), triple FDCAN interfaces, and hardware crypto acceleration (AES-128/192/256, SHA-2, HMAC). It targets high-performance industrial HMI, motor control gateways, and secure edge nodes requiring real-time graphics and deterministic communication.

For engineers reviewing the STM32H730IBK6Q datasheet, STM32H730IBK6Q pinout, STM32H730IBK6Q application, or STM32H730IBK6Q equivalent, key selection criteria include its 550 MHz M7 core with L1 cache, 564 KB ECC-protected SRAM split across TCM and system RAM, triple FDCAN support for automotive-grade networking, Chrom-ART accelerator for XGA LCD-TFT rendering, and on-the-fly Octo-SPI decryption for secure external code execution.

Technical Context

The STM32H730IBK6Q integrates a dual-bank Arm Cortex-M7 core with 32 KB instruction and 32 KB data caches enabling zero-wait-state execution, coupled with a Memory Protection Unit (MPU) and 2778 CoreMark performance. Its memory subsystem includes 128 KB embedded flash with ECC, 128 KB data TCM RAM for time-critical variables, and 432 KB system RAM-up to 256 KB remappable as instruction TCM RAM.

It implements three independent FDCAN controllers compliant with ISO 11898-1:2015, supporting bit rates up to 5 Mbps and protocol-level FD frame handling; the Chrom-ART Accelerator (DMA2D) offloads 2D graphics composition tasks from the CPU, while dual 16-bit ADCs operate in interleaved mode at 7.2 MSPS for high-fidelity sensor acquisition in motor control and power conversion systems.

FAQ

What is the maximum operating frequency and core configuration of the STM32H730IBK6Q?

The STM32H730IBK6Q features a single Arm Cortex-M7 core running at up to 550 MHz, with double-precision floating-point unit (DP-FPU), 32 KB instruction cache, and 32 KB data cache. It does not include a dual-core configuration; the M7 core is the sole application processor, with no companion M4 or M0+ co-processor on this variant.

Does the STM32H730IBK6Q support secure boot and firmware encryption?

Yes. It includes a bootloader with Security Firmware Installation (SFI) and Secure Boot and Secure Firmware Update (SB-SFU) services. Two on-the-fly decryption engines (OTFDEC) enable real-time AES-128 decryption of external Octo-SPI flash contents, and hardware crypto accelerators support AES-128/192/256, SHA-2, and HMAC for authenticated boot and firmware validation.

How many FDCAN interfaces does the STM32H730IBK6Q provide, and what standards do they support?

The STM32H730IBK6Q integrates three fully independent FDCAN controllers compliant with ISO 11898-1:2015. Each supports Classical CAN and CAN FD frames, bit rates up to 5 Mbps in FD mode, programmable data field lengths (up to 64 bytes), and hardware message filtering with Rx FIFOs - enabling concurrent multi-domain automotive or industrial network communication.

What is the package type and pin count of the STM32H730IBK6Q, and is it pin-compatible with other STM32H730 variants?

The STM32H730IBK6Q uses a 100-pin TFBGA package (8 × 8 mm, 0.8 mm pitch, A08Q footprint). It shares identical pinout and electrical characteristics with other STM32H730xB variants in the same TFBGA100 package (e.g., STM32H730VBT6), enabling drop-in replacement within the same package family - provided flash and peripheral requirements align.
