STM32F407IEH6TR Overview
A microcontroller is a programmable semiconductor system that integrates a processor core, memory, peripherals, and communication interfaces on one device. The STM32F4 MCU family belongs to the embedded-microcontroller hierarchy, where an Arm Cortex-M4 RISC core executes real-time control algorithms. Its hardware peripherals offload tasks that would otherwise burden the CPU, making the platform suitable for connected industrial, communications, audio, and embedded control products.
Key features include the 168 MHz maximum core frequency, single-cycle multiplication, DSP instructions, an FPU, and the ART Accelerator for zero-wait-state Flash execution. The verified references also identify a memory protection unit and up to 210 DMIPS, or 1.25 DMIPS/MHz with Dhrystone 2.1. These features support responsive control loops and arithmetic-intensive firmware while preserving deterministic peripheral access.
The STM32F407IEH6TR belongs to the STM32F407 high-performance family. Its integrated Ethernet MAC supports network-connected equipment, while the camera interface suits embedded imaging and vision systems. The combination of large embedded memory and a high-speed CPU is also valuable for audio processing, industrial gateways, and multifunction control boards that need fewer external components.
Typical uses include industrial automation, Ethernet gateways, camera-based inspection, audio controllers, communications equipment, and real-time embedded systems. Firmware portability requires checking peripheral assignments, pin multiplexing, startup support, clock configuration, and memory-map compatibility whenever moving between STM32 variants. The manufacturer product page and datasheet should govern final design decisions.
When designing the PCB, follow the manufacturer's land pattern, ball assignment, decoupling, and routing guidance. Keep high-speed clocks and communication signals short, provide clean references for analog interfaces, and validate power sequencing before production. Because the exact pin list, electrical limits, and package drawing are not included in the supplied search extract, consult the official STM32F407IEH6TR documentation before layout release.
This page consolidates the verified distributor identity, memory and processor specifications, procurement links, family context, and practical replacement considerations. It adds engineering guidance beyond a basic distributor listing while clearly separating verified values from documentation that must still be checked during design qualification.

Typical Applications
STM32F407IEH6TR is suitable for 6 applications: Industrial Ethernet Control, Camera-Based Inspection, Audio Signal Processing, Embedded Communications Gateway, Real-Time Motor Control, Data Acquisition System.
Industrial Ethernet Control
The STM32F407IEH6TR fits industrial Ethernet control because its Cortex-M4 core operates up to 168 MHz and the verified family listing includes an Ethernet MAC. Firmware can combine network management, supervisory control, logging, and real-time peripheral handling in one device. The 512 KB Flash and 192 KB SRAM provide room for a communication stack and control application without immediately requiring external memory. Validate PHY selection, isolation, connector layout, clocking, and protocol timing against the manufacturer's hardware guidelines before release.
Recommended
Camera-Based Inspection
The camera interface and high-performance Cortex-M4 core make STM32F407IEH6TR relevant to compact machine-vision and inspection controllers. The device can coordinate image capture, exposure sequencing, sensor control, and edge processing while retaining network connectivity through its Ethernet MAC. Its 512 KB Flash supports bootloader and application firmware, while 192 KB SRAM helps buffer data and execute DSP-oriented routines. Camera bandwidth, sensor timing, DMA behavior, and memory placement must be checked with the exact camera and MCU electrical documentation.
Recommended
Audio Signal Processing
For embedded audio, the STM32F407IEH6TR provides DSP instructions, an FPU, and a core frequency of up to 168 MHz. Those resources support real-time filtering, mixing, effect processing, and control logic while the 192 KB SRAM accommodates short audio buffers. The device can coordinate audio peripherals, communications, and user controls in a single controller. The verified material does not specify audio interface counts or codec support, so the exact audio path must be confirmed from the full datasheet before selecting a codec or amplifier.
Recommended
Embedded Communications Gateway
STM32F407IEH6TR is suitable for a communications gateway that must combine protocol processing, local control, and data buffering. Its 168 MHz Cortex-M4 performance, 512 KB Flash, 192 KB SRAM, and integrated Ethernet MAC provide a useful baseline for gateways that do not need an application processor. The MCU can supervise serial interfaces, update local parameters, and expose status through Ethernet. Validate protocol timing, RAM allocation, watchdog behavior, bootloader recovery, and network isolation in the target system.
Recommended
Real-Time Motor Control
The Cortex-M4 DSP instructions, FPU, and up-to-168 MHz operation can support real-time motor-control algorithms when the required timers, PWM outputs, and capture inputs are available on the selected variant. The STM32F407IEH6TR can centralize control loops, parameter updates, fault handling, and communications. Its 192 KB SRAM helps hold control state and diagnostic buffers. Before committing to a drive design, verify the exact pin multiplexing, timer channels, encoder interfaces, analog inputs, safety limits, and thermal conditions from the full manufacturer documentation.
Recommended
Data Acquisition System
STM32F407IEH6TR can serve as the control processor in a compact data-acquisition system because it combines high-speed computation, 192 KB SRAM, and extensive on-chip peripheral integration. Firmware can sample sensors, filter results, timestamp events, and transmit data through an Ethernet MAC. The FPU and DSP instructions help with fixed- or floating-point processing, while 512 KB Flash leaves room for calibration and communication code. Confirm the required ADC, timer, DMA, and external-interface resources for the exact package before design commitment.

Key Differentiators
- Higher verified core frequency than the compared STM32F429IEH6 listing (vs STM32F429IEH6)
- Larger SRAM in STM32F429IEH6 (vs STM32F429IEH6)
- Known 512 KB Flash configuration (vs STM32F407IET6)
- Explicit Cortex-M4 real-time processing features (vs STM32F407IET6)
Design Notes
Use the official STM32F407IEH6TR UFBGA land pattern and ball-reference drawing rather than a generic BGA footprint. Confirm all 176+25 ball assignments, power and ground balls, reserved balls, and the 10 mm by 10 mm package dimensions before routing. Place decoupling capacitors close to the relevant supply balls and keep high-speed clock and communication routes short.
The supplied verified extract confirms a 176+25 UFBGA device but does not provide its complete voltage table, regulator sequencing, or power-consumption figures. Before applying power, verify every supply rail, voltage tolerance, ground reference, and startup sequence in the current manufacturer datasheet. Program the clock tree only after the power rails and external support components meet the documented limits.
Do not estimate the junction temperature from the processor frequency alone. Calculate the actual package and board dissipation from the operating voltage, current, activity factor, and the manufacturer's thermal model. The supplied data does not provide theta-JA, theta-JC, or maximum junction temperature, so those values must be obtained from the official package and electrical documentation before a thermal sign-off.
Keep the 168 MHz clock distribution clean, provide the specified decoupling and source-load arrangement, and avoid routing sensitive signals beneath noisy or high-speed nets. Ethernet and camera interfaces require controlled impedance and return paths. The verified extract does not provide rise-time, I/O, or transceiver specifications, so use the complete datasheet and interface reference designs for final values.
A related STM32F407 or STM32F429 MPN is not automatically a replacement. Check the exact ordering suffix, package, temperature range, exposed-ball requirements, pin multiplexing, memory organization, and firmware startup assumptions. Also verify that Ethernet, camera, timer, and DMA assignments used by the existing PCB remain available after the substitution.
Compliance Information
The supplied verified results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Obtain current compliance declarations from STMicroelectronics or the authorized distributor.
