The STMicroelectronics STM32H745ZGT6 is a dual-core 32-bit ARM microcontroller integrating an Arm Cortex-M7 core running up to 480 MHz and a Cortex-M4 core running up to 240 MHz, packaged in a 144-pin LQFP (20x20 mm) with 1 MB of embedded Flash and approximately 1 MB of SRAM. It belongs to the high-performance STM32H7 family and is engineered for compute-intensive real-time control, motor drives, audio processing, and human-machine interface (HMI) applications where two heterogeneous cores share a workload - the M7 for DSP/graphics and the M4 for housekeeping, communications, or low-power task scheduling. As a microcontroller (MCU), the STM32H745ZGT6 sits in the broader taxonomy of embedded processing devices: MCU -> ARM Cortex-M MCU -> STM32 family -> STM32H7 high-performance series. It is a system-on-chip integrating CPU cores, memory, analog peripherals, and digital interfaces in a single package, programmed typically via STM32CubeIDE, STM32CubeMX, and the HAL/LL driver libraries. Key differentiating features include the dual-core asymmetric architecture (M7 + M4) with separate instruction caches, an integrated SMPS step-down converter for core supply (improving efficiency versus external LDOs), up to 2 MB Flash and 1 MB RAM across the full H745 line, a Chrom-ART graphics accelerator, JPEG codec hardware, and an extensive peripheral set including 16-/12-bit ADCs, DACs, timers, Ethernet, USB, CAN FD, and high-speed SPI/QSPI interfaces for external memory or displays. The device operates from 1.62 V to 3.6 V with internal SMPS generating the core voltage. Typical applications include industrial motor control (field-oriented control), audio amplifiers and DSP effects processors, HMI panels with TFT-LCD and touch, building automation, IoT edge gateways, programmable logic controllers, and medical instrumentation. The dual-core design enables deterministic real-time response on the M4 while the M7 executes complex algorithms without mutual blocking. When designing with this part, allocate a minimum 4-layer PCB with continuous GND pour around the LQFP-144 package to manage thermal dissipation at high clock speeds. Decouple each VDD/VBAT pin with 100 nF X7R ceramic capacitors placed within 2 mm of the respective pins. Use STM32CubeMX to configure the SMPS inductor and feedback compensation to achieve the specified core voltage ripple under your worst-case load transient.

STM32H745ZIT6

STM32H745ZIT6 - Dual-Core Cortex-M7/M4 MCU, 480MHz, 2MB Flash | STMicroelectronics

The STMicroelectronics STM32H745ZIT6 is a high-performance dual-core 32-bit microcontroller pairing an Arm Cortex-M7 core running up to 480 MHz with a Cortex-M4 core running up to 240 MHz, integrating 2 MB of Flash and 1 MB of SRAM in a 144-pin LQFP (20x20 mm) package. The device targets demanding real-time embedded workloads where DSP-grade signal processing, GUI rendering, and deterministic control must coexist on one silicon die. A Chrom-ART graphics accelerator and hardware JPEG codec offload pixel and image pipelines, while an integrated cryptographic accelerator handles AES, hash, and True Random Number Generator functions for secure connectivity. A microcontroller (MCU) is a compact, self-contained computer on a single integrated circuit that combines a processor core, volatile and non-volatile memory, programmable peripherals, and bus fabric. The STM32 family is STMicroelectronics' 32-bit Arm Cortex-M portfolio, with the STM32H7 series occupying the high-performance tier that bridges MCU and application-processor territory. The H745 sub-family adds heterogeneous dual-core asymmetric multiprocessing (AMP), so heavy graphics and DSP work runs on the M7 while time-critical control loops run independently on the M4. Key differentiating features include 480 MHz Cortex-M7 with double-precision FPU, 240 MHz Cortex-M4 with single-precision FPU, 2 MB dual-bank Flash for live firmware updates, 1 MB SRAM split across DTCM, AXI SRAM, and SRAM1-4 domains, and an extensive peripheral set including Ethernet, USB 2.0 HS, CAN-FD, SDMMC, three 12-bit ADCs up to 3.6 MSPS, two 12-bit DACs, and TFT LCD interface. Operating voltage spans 1.62 V to 3.6 V with multiple low-power modes (D1 Stop, Standby, VBAT) for energy-constrained designs. Architecturally, the device is built on ST's 40 nm low-power process and uses a multilayer AHB/APB bus matrix plus an AXI-to-DTCM bridge so each core can fetch zero-wait-state from its private TCM. The Cortex-M7 issues single-precision and double-precision floating-point instructions natively, while the Cortex-M4 handles real-time control and housekeeping. Dedicated DMA controllers (MDMA, DMA1/DMA2) keep peripherals fed without CPU intervention, enabling overlapped computation and data movement. Typical applications include industrial motor control and field-oriented drive (FOD) inverters, smart-home gateways with embedded graphics, audio processing and effects units, advanced HMI panels, factory automation PLCs, and high-end consumer devices requiring simultaneous DSP and GUI work. The dual-core split makes it a strong fit for protocols stacks (M4) plus UI/DSP (M7) architectures. When designing with this device, allocate decoupling capacitance close to every VDD/VDDA/VBAT pin and place the four-layer break-out symmetric around the exposed pad to dissipate the M7's dynamic power. Use the ST MC SDK for motor control and STM32CubeIDE plus TouchGFX for HMI development, and respect the boot pin strapping for Flash boot versus system memory bootloader. Cross-check VCAP pins with the reference schematic to avoid reset instability.

The 169-UFBGA package provides dense pin count and efficient signal routing for high-IO applications. The dual-core architecture allows one core to handle real-time deterministic control while the other runs HMI graphics, communication stacks, or DSP algorithms. The on-chip SMPS supplies the M7 core directly with high current capability while keeping the external supply topology simple. Hardware crypto accelerators (AES, SHA, TRNG) and secure-boot features enable secure firmware updates for connected products. Typical applications include human-machine interface (HMI) panels with TFT or MIPI-DSI displays, industrial motor control and drives, audio processing units, point-of-sale terminals, smart appliances, building automation gateways, and high-performance IoT edge nodes. The dual cores allow an RTOS to run on the M4 while complex code paths execute on the M7 with full DSP and FPU support. When designing with this device, place the 100 nF + 4.7 µF decoupling network as close as possible to each VDD pin, and assign the SMPS inductor to its dedicated pins with the shortest loop possible. Boot mode and option bytes should be reviewed early in the schematic to avoid lockout conditions on first prototypes.

STM32H750IBK6

STM32H750IBK6 - 480MHz Cortex-M7 MCU, 1MB RAM | STMicroelectronics

The STMicroelectronics STM32H750IBK6 is a high-performance 32-bit Arm Cortex-M7 microcontroller operating at up to 480 MHz, featuring 128 KB of embedded Flash and 1 MB of SRAM, in a 176+25-pin UFBGA (10x10 mm) package. The part integrates a single-precision FPU, 16 KB + 16 KB of L1 instruction/data cache, hardware JPEG codec, AES-256, Hash and True Random Number Generator (TRNG) crypto accelerators, and an 8- to 16-bit parallel external memory interface for SDRAM, SRAM, and NOR/NAND Flash expansion. 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.

STM32H750XBH6U

STM32H750XBH6U - 480MHz 128KB MCU | STMicroelectronics

STMicroelectronics STM32H750XBH6U is a 32-bit Arm Cortex-M7 microcontroller operating at up to 480MHz, with 128KB of flash memory and a 265-ball TFBGA package. The supplied distributor records identify a 14 mm by 14 mm package; a related STM32H750XBH6 listing identifies 240 plus 25 balls and 128KB organized as 128K by 8. Available component-market pricing starts at $3.9251, and one distributor listing reports 7,056 pieces in stock as of the supplied data. A microcontroller is an embedded semiconductor that integrates a processor core, memory, peripherals, and communication interfaces on one device. The STM32H7 family belongs to the Arm Cortex-M microcontroller hierarchy and combines real-time control capability with substantial data-processing throughput. This product is therefore positioned between a conventional embedded control MCU and a higher-performance Cortex-M7 system for control, communications, graphics, and signal-processing workloads. The verified listing identifies an Arm Cortex-M7 processor, 32-bit architecture, 480MHz maximum frequency, 128KB flash, and a 265-TFBGA package. The cross-reference data also describes 1MB RAM and 46 communication and analog interfaces, but these values were not explicitly tied to the complete STM32H750XBH6U manufacturer record and are therefore treated cautiously. The device's high-frequency Arm Cortex-M7 core provides substantial processing headroom for interrupt-heavy control, protocol handling, and embedded user-interface logic. Applications supported by the device class include industrial automation, networking equipment, motor control, test and measurement, human-machine interfaces, and connected embedded systems. At 480MHz, the MCU can process complex state machines and peripheral data faster than lower-frequency general-purpose microcontrollers. Designers must still budget for cache configuration, memory latency, clock-tree setup, thermal behavior, and deterministic peripheral timing rather than interpreting clock speed as the only performance measure. The BGA package supports dense PCB routing but requires inspection and assembly capability. A 0.5 mm pitch package is mechanically demanding, so fine-pitch assembly, via-in-pad considerations, solder mask definition, and adequate thermal-via distribution should be reviewed before release to manufacturing. The board should also follow the manufacturer's pinout, power, decoupling, clock, and exposed-pad guidance in the official device documentation. This page consolidates verified distributor pricing, availability, package details, and cross-reference findings. It distinguishes confirmed target-device data from family-level information and avoids treating merely related STM32H7 devices as drop-in replacements. Engineers should use the manufacturer documentation and exact MPN comparison before approving any substitution.

STM32H750ZBT6 - 480MHz Cortex-M7 MCU 128KB Flash | STMicroelectronics
STM32H750ZBT6

STM32H750ZBT6 - 480MHz Cortex-M7 MCU 128KB Flash | STMicroelectronics

The STMicroelectronics STM32H750ZBT6 is a high-performance 32-bit ARM Cortex-M7 microcontroller operating at up to 480 MHz, packaged in a 144-pin LQFP (20x20 mm). It integrates 128 KB of Flash, 1 MB of RAM, hardware crypto, JPEG codec, and an external memory interface. The device targets demanding embedded applications that require strong DSP, floating-point, and graphics performance without an external memory bus complexity penalty. A microcontroller (MCU) is an integrated circuit that combines a processor core, memory, and programmable peripherals on a single die. ARM Cortex-M7 cores add a six-stage superscalar pipeline, single-precision and double-precision floating-point unit (FPU), and tightly-coupled memory (TCM) for deterministic real-time response. The STM32H7 family sits at the high-performance tier of the STM32 portfolio, above Cortex-M4 parts (STM32F4) and below Cortex-A application processors. The H750 specifically trims Flash to 128 KB while retaining 1 MB SRAM, making it well-suited for code execution from external QSPI memory while keeping on-chip RAM for buffers and frame data. Key features of the STM32H750ZBT6 include 480 MHz CPU clock, 1 MB SRAM, Chrom-ART graphics accelerator, hardware AES-256 / SHA-256 / TRNG, two SDMMC interfaces, an 8- to 14-bit camera interface, and up to 16-bit external memory bus for SRAM, PSRAM, NOR, NAND, and SDRAM. The LQFP-144 package exposes 114 GPIO across multiple 5V-tolerant banks and offers 16-bit ADC, comparators, op-amps, and 12-bit DAC peripherals. The device is built on a 40 nm low-power CMOS process and supports four low-power modes (Sleep, Stop, Standby, VBAT) with RTC and backup registers retained in Standby. CoreMark performance reaches 1023 CoreMark at 480 MHz / 4.08 CoreMark/MHz. The dual-domain supply (Vcore plus VDD/VDDA) requires careful decoupling but enables dynamic voltage scaling to trade frequency for power consumption. Typical applications include industrial motor control, human-machine interface (HMI) panels with TFT-LCD, audio processing with USB streaming, secure IoT gateways, drone flight controllers, and portable medical instrumentation. The 1 MB on-chip RAM is enough to run LVGL graphical stacks and audio buffers without external PSRAM, simplifying board layout. When designing with this part, allocate a 4.7 µF bulk capacitor plus 100 nF decoupling per supply pin, follow ST's AN4661 PCB layout guide for high-speed signals, and reserve QSPI traces for short length-matched routing. The 128 KB internal Flash is often not enough for production firmware; use the Quad-SPI interface to boot XIP from an external Flash and treat internal Flash as a backup/bootloader region.

STM32H753IIT6 - Cortex-M7 MCU 480MHz 2MB Flash 176-LQFP | ST
STM32H753IIT6

STM32H753IIT6 - Cortex-M7 MCU 480MHz 2MB Flash 176-LQFP | ST

The STMicroelectronics STM32H753IIT6 is a high-performance 32-bit ARM Cortex-M7 microcontroller with double-precision FPU, operating at up to 480 MHz, delivering 1027 DMIPS / 2424 CoreMark performance, and integrating 2 MB of Flash and 1 MB of SRAM in a 176-pin LQFP (24x24 mm) package. The Cortex-M7 core includes a 16 KB I-cache and 16 KB D-cache plus a tightly-coupled memory (TCM) interface, enabling deterministic real-time execution alongside DSP extensions and a double-precision floating-point unit for signal-processing and machine-learning edge workloads. An MCU (microcontroller) is a single-chip computer that integrates a CPU core, Flash program memory, SRAM data memory, and a rich set of analog and digital peripherals on one die. Microcontrollers sit at the bottom of the embedded-computing hierarchy (microcontroller -> SoC -> microprocessor -> computer) and dominate applications where deterministic real-time response, low BOM cost, and low power are critical. The STM32H7 family specifically represents ST's high-performance tier, adding advanced peripherals such as a hardware JPEG codec, crypto/hash accelerators, and an external memory interface for SDRAM/NOR/NAND expansion. Key features of the STM32H753IIT6 include Chrom-ART (DMA2D) graphical accelerator for TFT-LCD driving, three 12-bit ADCs at 3.6 MSPS each, two 12-bit DACs, USB 2.0 OTG full-speed/high-speed with on-chip PHY, two CAN FD controllers, an SDMMC interface for eMMC/SD cards, and a MIPI-DSI controller for displays. It also integrates a true random-number generator (TRNG), AES-256 and SHA-256 hardware accelerators, and a parallel 16-bit FMC bus capable of addressing external SDRAM. The architecture combines a Cortex-M7 main core with a smart architecture of power domains, allowing Stop/Standby modes that drop consumption below 100 uA while retaining RTC and backup SRAM. The L1 cache, TCM, and ART Accelerator reduce Flash wait-states at 480 MHz, so iterative DSP loops execute from cache with single-cycle access. The combination of high core frequency, large on-chip memory, hardware crypto and graphics support distinguishes the H753 from earlier STM32F7 parts. Typical applications include industrial HMI panels with TFT-LCD graphics, motor-control drives (FOC, servo, robotics), audio DSP and audio codecs with USB streaming, point-of-sale terminals, smart-home gateways, and edge-AI sensor fusion nodes. The hardware crypto and the parallel camera interface (DCMI) also suit barcode scanners and machine-vision front-ends. A key design consideration is the dual-rail supply requirement: the H753 needs a 1.2 V core supply generated by the internal SMPS or an external LDO, plus a 3.3 V I/O rail. Power-rail sequencing and decoupling are critical - bypass capacitors must be placed as close as possible to the four VDD/VDDA/VCAP pin groups to avoid core instability. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical hardware design notes that are not found in any single manufacturer datasheet, helping procurement and embedded engineers evaluate the STM32H753IIT6 for new BOMs and second-source projects.

STM32H753XIH6

STM32H753XIH6 - 480MHz Cortex-M7 MCU, 2MB Flash, TFBGA-176

The STMicroelectronics STM32H753XIH6 is a high-performance 32-bit ARM Cortex-M7 microcontroller running up to 480 MHz with double-precision FPU, 16 Kbytes of instruction cache, 16 Kbytes of data cache, and DSP instructions, delivering 1027 DMIPS / 2.14 DMIPS/MHz (Dhrystone 2.1). It integrates 2 Mbytes of Flash memory and 1 Mbyte of SRAM in a 176-ball TFBGA (XIH) package. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), working memory (RAM), and a rich set of programmable peripherals. Within the broader semiconductor taxonomy, an MCU sits between microprocessors (MPUs, which require external RAM/Flash) and ASICs. The STM32H7 family specifically targets high-performance, DSP-rich applications where both real-time control and high-throughput signal processing coexist on one die. Key features of the STM32H753XIH6 include Chrom-ART graphical accelerator for offloading 2D drawing, JPEG codec hardware, two 16-bit ADCs, two 12-bit DACs, USB OTG FS and HS with on-the-fly PHY, CAN FD, Ethernet MAC, SDMMC, and a parallel 16-bit FMC interface. The device also includes a true random number generator (TRNG), cryptographic accelerators (AES, SHA, RSA), and an integrated SMPS step-down converter for core power. Architecturally, the part uses ST's 40 nm low-power CMOS process with an L1 cache around the Cortex-M7 core to push single-core throughput to 480 MHz without inflating power dissipation. The AXI multi-layer bus matrix gives DMA-fed peripherals and the CPU concurrent access to SRAM, Flash, and external memories. Internal regulators (SMPS + LDO) can be controlled in software to trade idle current for wake-up latency. Typical applications include industrial motor control, three-phase solar inverters, audio DSP and effects units, point-of-sale terminals, smart appliances, gateways with on-chip Ethernet, and human-machine interface (HMI) panels using an external TFT. The TFBGA-176 footprint also suits portable medical instrumentation, where size and DSP throughput matter equally. When designing with this MCU, allocate a 1 Mbyte Flash sector plan early; 2 Mbytes is generous but external code (JPEG, USB stacks, TCP/IP) consumes it quickly. Choose the boot mode pins (BOOT0, BOOT1) carefully during PCB layout, and provision enough decoupling capacitance near the SMPS input. This page combines verified distributor pricing, drop-in pin-compatible alternatives, and application-grade design notes that go beyond the standard datasheet summary, giving engineers a single decision-ready reference.

It integrates 2 MB of on-chip Flash and 1 MB of SRAM, packaged in a 240+25-ball TFBGA (14x14 mm) that is supplied on 7-inch Tape & Reel (the TR suffix denotes the tape-and-reel packaging option of the STM32H753XIH6 bare-chip version). What is a Cortex-M7 MCU? An ARM Cortex-M7 microcontroller is the highest-performance core in the Cortex-M family, targeting applications that previously required a Cortex-M4 or even a Cortex-A application processor. It combines an in-order superscalar pipeline with single- and double-precision floating-point, tightly-coupled memory, and an instruction/data cache. Hierarchy: Cortex-M7 -> Cortex-M -> 32-bit MCU -> microcontroller -> embedded computing. The STM32H7 family extends this with ST's smart peripheral architecture for motor control and high-speed data acquisition. Key features include 480 MHz core speed, 2 MB dual-bank Flash with read-while-write support for live firmware updates, 1 MB SRAM split into DTCM, AXI-SRAM, SRAM1-4, and Backup domains, an 8- to 14-bit ADC up to 3.6 MSPS, USB 2.0 OTG full-speed/high-speed, two CAN 2.0B interfaces, an Ethernet MAC with 10/100-Mbit/s MII/RMII, two SAIs for audio, an SDMMC interface for SD-cards, and integrated crypto/hash accelerators (AES-256, SHA-1/SHA-2, True Random Number Generator).

The architecture pairs a Cortex-M7 with an optional Cortex-M4 in dual-core STM32H745/H755 parts, but the STM32H753XIH6TR is single-core to free die area for the largest memory configuration. A 4 KB battery-domain backup SRAM, 32 kHz RTC, and 16 hardware timers support industrial deterministic scheduling. Typical applications include industrial motor drives (field-oriented control of PMSM/BLDC at 50 kHz loops), high-end audio DSP (SAI/I2S to DAC/ADC), Human-Machine Interface TFT-LCD panels up to XGA resolution with TFT controller and Chrom-ART accelerator, edge AI/ML inference at the network edge, and EtherCAT-slave or Profinet device front-ends. Designers should ensure the external SMPS/linear regulator network feeding VCAP pins provides sufficient bulk capacitance during 480 MHz bursts, and that the high-speed SDRAM interface uses matched-length routing to preserve timing margin.

STM32H755ZIT6

STM32H755ZIT6 - Dual-Core Cortex-M7/M4 MCU, 2MB Flash | STMicroelectronics

The STMicroelectronics STM32H755ZIT6 is a high-performance dual-core 32-bit Arm microcontroller combining a Cortex-M7 core operating up to 480 MHz and a Cortex-M4 core up to 240 MHz, with 2 MB of dual-bank flash and 1 MB of SRAM in a 144-pin LQFP (20x20 mm) package. It targets industrial HMI, motor control, audio processing and edge-AI applications where heterogeneous compute partitioning between deterministic real-time control and high-throughput DSP/graphics is required. According to the STMicroelectronics product page, the STM32H755xI line integrates a Chrom-ART Accelerator, hardware crypto/hash accelerators, and a true random number generator. A microcontroller (MCU) is a compact integrated circuit that combines a processor core, on-chip memory (flash and SRAM), and programmable peripherals used to govern a specific operation in an embedded system. The STM32H755ZIT6 belongs to the STM32H7 family, which sits at the top of the ST Cortex-M portfolio between the mainstream STM32F4/F7 lines and the lower-power STM32L4/U5 lines. Its dual-core architecture enables one core to handle time-critical control while the other runs communication stacks, GUI rendering, or machine-learning inference, with shared access to peripherals through a bus-matrix arbitration scheme. Key differentiating features include the 480 MHz Cortex-M7 with double-precision FPU and L1 cache, the 240 MHz Cortex-M4 with single-precision FPU, 2 MB flash with read-while-write support, 1 MB SRAM split across DTCM, AXI SRAM and SRAM1/2/3 domains, and an integrated SMPS step-down converter for high-efficiency core supply. The device exposes 114 GPIO, 35 communication interfaces (including Ethernet, USB OTG HS/FS, CAN FD, SPI, I2C, UART, SDMMC), three 16-bit ADCs up to 3.6 MSPS, two 12-bit DACs, two SAI for audio, an LCD-TFT controller, a JPEG codec, and a crypto/hash suite compliant with AES, SHA and RSA. Built on a 40 nm low-power CMOS process, the part operates from 1.62 V to 3.6 V on VDD and supports an industrial -40 °C to +85 °C temperature range. The dual-bank flash with read-while-write capability simplifies in-field firmware upgrades and A/B partition schemes, while the Chrom-ART accelerator offloads 2D drawing to free the Cortex-M7 for application code. The integrated SMPS reduces core current draw by roughly 30% compared to an external LDO-only supply, easing thermal design in compact enclosures. Typical applications include industrial HMI panels with TFT LCD, motor-control inverter boards, smart-home gateways, audio DSP front-ends with SAI-to-DAC chains, vision-based edge-AI nodes using the JPEG codec, and medical instrumentation requiring deterministic USB or Ethernet connectivity. The dual-core topology is especially valuable when a real-time control loop must coexist with a Linux-like user interface stack on the same die. When designing with this device, treat the SMPS inductor selection as critical because ripple directly couples into the core logic rail. Provide a 4.7 µF input bulk plus 100 nF + 1 µF ceramic decoupling near each VDD pin, and follow the ST reference layout for the 240 MHz M7 traces to avoid signal-integrity issues. Boot pins BOOT0 and the option-byte bank must be configured before each power cycle, otherwise the part may revert to system memory bootloader.

STM32H757XIH6

STM32H757XIH6 - Dual-Core M7/M4 MCU, 2MB Flash, TFBGA-240 | STMicroelectronics

The STMicroelectronics STM32H757XIH6 is a high-performance dual-core microcontroller pairing an Arm Cortex-M7 core running up to 480 MHz with a Cortex-M4 core running up to 240 MHz, integrating 2 MB of flash and 1 MB of SRAM in a 240+25-ball TFBGA (14x14 mm) package. It belongs to the STM32H7 family, ST's flagship line of 32-bit microcontrollers designed for compute-intensive embedded workloads. A microcontroller (MCU) is a compact integrated circuit containing a processor core, on-chip memory (Flash and SRAM), and programmable peripherals, used to govern a specific function in an embedded system. The category spans from simple 8-bit controllers up to high-performance 32-bit dual-core devices like the STM32H7 series. Within ST's portfolio hierarchy, the STM32H7 sits above STM32F7, STM32L4, and STM32G4 families, targeting applications that require intensive computation, rich connectivity, and real-time responsiveness. Key features of the STM32H757XIH6 include the asymmetric dual-core architecture enabling workload partitioning between high-performance DSP/AI tasks (M7) and real-time control (M4), an integrated SMPS step-down converter for core supply efficiency, a hardware cryptographic accelerator with AES, hash, and true random number generator (TRNG), a Chrom-ART 2D graphics accelerator, an MIPI-DSI interface for displays, and 46 communication and analog interfaces including Ethernet, USB, CAN-FD, USART, SPI, I2C, multiple ADCs and DACs. The 1.62V to 3.6V supply range supports battery-backed operation. From a technical depth perspective, the device leverages ST's 40 nm low-power CMOS process, which enables the M7 core to sustain 480 MHz at Cortex-M7 performance levels with DSP extensions while keeping the M4 core running real-time tasks independently. The 2 MB dual-bank flash supports read-while-write operation, allowing one bank to execute code while the other is updated. A 16-stream DMA controller offloads data movement, and the flexible memory controller (FMC) extends the system with external SDRAM, NOR, or NAND flash. Typical applications include industrial PLC and HMI panels, motor-control drives (field-oriented control of PMSM and BLDC motors), high-end audio processors, medical patient monitoring, advanced driver-assistance systems (ADAS), robotics controllers, and smart-home/IoT edge gateways. The dual-core design is particularly suited to systems that must simultaneously run a graphical UI on the M7 and a deterministic control loop on the M4. When designing with the STM32H757XIH6, place 100 nF decoupling capacitors close to every VDD pin and use a bulk capacitor on the main 3.3 V rail. Boot-mode pins (BOOT0 and options bytes) must be configured correctly to select the desired boot source (Flash, system memory bootloader, or SDRAM). The TFBGA-240 package requires a 14x14 mm PCB land pattern with 0.8 mm ball pitch, and thermal copper area should be sized to keep junction temperature below 125 °C at full M7 load. This page synthesizes distributor pricing, drop-in TFBGA alternatives, and practical dual-core design notes not found in the manufacturer datasheet, giving engineers a single source for BOM decisions.
