STM32F745IET7 - 216MHz Cortex-M7 MCU | STMicroelectronics
MPN: STM32F745IET7 ✓ AktifSTM32F745IET7 Ringkasan
A microcontroller is a programmable semiconductor system containing a processor core, nonvolatile program memory, working memory, and peripheral interfaces on one integrated circuit. Within the product hierarchy, the STM32F745IET7 is an MCU, a microcontroller IC, an embedded processor, and ultimately a semiconductor. Its ARM Cortex-M7 architecture supports real-time control while the single-precision floating-point unit and DSP instructions accelerate suitable arithmetic operations without requiring a separate accelerator.
Verified product information identifies a maximum operating frequency of 216 MHz, 512 KB of flash organized as 512 K by 8 bits, and a 176-LQFP package with 24 mm by 24 mm dimensions. The Cortex-M7 core implements Arm single-precision floating-point instructions and data types as well as a full set of DSP instructions. These features make the MCU suitable where conventional control tasks benefit from higher computational throughput.
The STM32F7 family provides a high-performance platform for embedded control, communications, data acquisition, and industrial equipment. At 216 MHz, the processor can service time-sensitive control loops and peripheral events while executing more computationally intensive application tasks. Its 512 KB flash capacity provides room for a bootloader, operating software, configuration data, and application firmware within one integrated package.
Typical applications include industrial automation, motor and motion control, communications equipment, instrumentation, and embedded user interfaces. The single-precision floating-point capability is particularly relevant to sensor conditioning, digital filtering, and control algorithms, while the DSP instruction set can improve throughput for suitable signal-processing operations.
Designers should verify the complete STM32F745xx and STM32F746xx datasheet for the exact peripheral map, power requirements, electrical limits, pin multiplexing, and package dimensions before layout release. Particular attention is required to decoupling, clock configuration, analog grounding, signal integrity, and unused-pin handling because the verified source data supplied for this part does not include a complete 176-pin assignment.
This page combines manufacturer specifications, distributor availability information, sourcing context, and verified drop-in alternatives. It also distinguishes electrically interchangeable ordering variants from options that change temperature grade or memory configuration, helping engineers make PCB-level replacement decisions without assuming that every STM32F745 or STM32F746 designation is automatically interchangeable.

Aplikasi Biasa
STM32F745IET7 patut untuk 6 aplikasis: Industrial Automation Controllers, Motor and Motion Control, Industrial Communications Equipment, Precision Instrumentation, Data Acquisition Systems, Embedded Graphical User Interfaces.
Industrial Automation Controllers
The STM32F745IET7 fits industrial automation controllers that require deterministic control alongside a relatively capable signal-processing core. Its 216 MHz Arm Cortex-M7 processor provides more throughput than an entry-level microcontroller, while the single-precision FPU and DSP instructions can support filtering and control calculations. The 512 KB of embedded flash is sufficient for an integrated control application containing firmware, configuration, and diagnostics. A designer should use the 176-LQFP footprint for an existing LQFP-176 design, but must still verify clock, supply, peripheral, and pin multiplexing against the manufacturer datasheet before production release.
Disebarkan
Motor and Motion Control
The STM32F745IET7 is suitable for motor and motion-control logic requiring faster computation than a basic control MCU. The 216 MHz Cortex-M7 core can execute timing-intensive control loops, while its single-precision floating-point unit supports common proportional, integral, derivative, and filtering operations. DSP instructions may improve suitable fixed-point processing workloads. The 512 KB flash permits the application firmware and parameter set to reside on-chip. Final suitability depends on the available timer outputs, analog channels, encoder interfaces, and real-time interrupt behavior, none of which were included in the supplied verification snippets.
Disebarkan
Industrial Communications Equipment
The STM32F745IET7 can serve as the host controller in industrial communications equipment where protocol handling and real-time peripheral servicing must coexist. Its 216 MHz Cortex-M7 performance provides headroom for communication stacks, diagnostics, and control tasks, while 512 KB of flash supports a consolidated firmware image. The 176-LQFP package provides a substantial pin count for external interfaces and debugging. Engineers must confirm the exact Ethernet, UART, USB, and other peripheral resources in the STM32F745xx datasheet, along with impedance-controlled routing and transceiver requirements for the selected communications standard.
Disebarkan
Precision Instrumentation
The STM32F745IET7 is appropriate for precision instrumentation that combines sensor acquisition, numerical processing, and a human-machine interface. The single-precision FPU and DSP instruction set can accelerate digital filtering and calibration algorithms, while the 216 MHz core leaves processing margin for measurement control and communications. Its 512 KB flash provides room for embedded application code without an external program-memory device. The 176-LQFP footprint offers access to a large pin count, but analog accuracy, reference noise, ADC characteristics, and grounding must be verified against the manufacturer data before claiming metrology performance.
Disebarkan
Data Acquisition Systems
The STM32F745IET7 can be used in data-acquisition systems where sampling control, buffering, filtering, and host communication require more compute capacity than a basic MCU. At up to 216 MHz, the Cortex-M7 core can coordinate peripheral-driven acquisition and execute digital signal-processing functions, supported by single-precision floating-point hardware. The 512 KB flash stores application firmware and configuration. Actual acquisition rate and channel count depend on the verified ADC, timer, and DMA implementation, so designers should review the complete pinout and electrical characteristics rather than inferring peripheral capabilities from the headline processor frequency.
Disebarkan
Embedded Graphical User Interfaces
The STM32F745IET7 is a strong candidate for embedded graphical user-interface controllers because its 216 MHz Cortex-M7 core and 512 KB of flash can support more demanding interface logic than a minimal microcontroller. The single-precision FPU may assist color, scaling, and filtering operations, while the 176-pin LQFP provides numerous configurable connections for a display and input peripherals. External display memory and controllers may still be required depending on panel resolution. Developers should confirm available camera, LCD, SDRAM, DMA, and display-interface resources in the manufacturer datasheet and validate timing during hardware bring-up.

Catatan Desain
Before schematic release, verify every supply rail, decoupling capacitor, power-supply startup sequence, and operating-voltage limit against the STM32F745xx and STM32F746xx manufacturer datasheet. The supplied data confirms a 3.3 V device but does not include the complete power architecture. Place required bulk and high-frequency decoupling close to the relevant supply and ground pins, and validate the rail during processor startup, low-frequency operation, and maximum peripheral load.
Because the verified package is a 176-LQFP with 24 mm by 24 mm body dimensions, use the manufacturer land pattern and the PCB library’s verified courtyard and paste geometry rather than relying only on nominal body size. Check drill, lead span, annular ring, solder-mask, and paste-reduced constraints. Pin assignment was not included in the supplied data, so do not release artwork until the 176-pin diagram and alternate-function table have been cross-checked.
Review each high-speed or sensitive signal in the final pin-multiplexing scheme, including clock, communication, debug, and analog inputs. The source material does not provide a complete pinout or peripheral configuration, so trace topology, impedance, grounding, and peripheral instance mapping cannot be finalized from this page. Use short return paths, continuous reference planes, and controlled escape routing, and follow the manufacturer hardware-design guidance for sensitive interfaces.
Do not treat every STM32F745 or STM32F746 order code as interchangeable. Memory density, temperature grade, package, and order suffix can change electrical qualification even when the family name is the same. The listed alternatives retain the same 176-LQFP footprint and 512 KB memory arrangement, but the engineer must confirm temperature, marking, pinout, and lifecycle requirements from the manufacturer ordering information before treating either alternative as an approved second source.
Maklumat Kesediaan
