STM32F745IGT6 - 216MHz Cortex-M7 MCU | STMicroelectronics
MPN： STM32F745IGT6 ✓ 啟用中STM32F745IGT6 概覽
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripheral interfaces on one package. The STM32F7 family belongs to the hierarchy of 32-bit MCU, embedded microcontroller, embedded processor, and semiconductor. Its Arm Cortex-M7 core provides the central processing platform, while Flash stores firmware and RAM supports active data, stack operations, and peripheral buffers. A 176-pin LQFP also provides a substantial number of external connections relative to smaller MCU packages.
The principal verified features include a 216 MHz maximum core frequency, 32-bit processing, 1 MB of 1M x 8 Flash, 340 KB of RAM, a 176-pin LQFP package, and operation from a stated 3.3 V supply. These specifications suit applications that require more flash storage and I/O capacity than a small general-purpose MCU, particularly when code size, external connectivity, and control integration drive component selection. The manufacturer describes the STM32F745xx family as high-performance Cortex-M7 devices operating up to 216 MHz.
The STM32F745IGT6 belongs to the same high-performance STM32F7 family as the STM32F746xx devices. The MCU is suitable for industrial automation, communications equipment, embedded control systems, audio and digital signal processing, and data-acquisition platforms. Because the supplied evidence does not enumerate the peripheral mix, pin names, electrical limits, or memory breakdown beyond the verified headline figures, those details should be confirmed in the official product documentation before schematic capture.
When designing a board around this controller, begin with the manufacturer pinout and reference design guidance rather than assigning LQFP pins from memory. Validate the regulator, decoupling network, clock strategy, debug programming interface, and exposed peripheral requirements against the exact STM32F745IGT6 package. A 176-pin footprint also demands careful PCB escape routing and assembly planning to avoid fine-pitch soldering or inspection defects.
For sourcing, DigiKey lists the part as buyable and ships today, while LCSC reports in-stock inventory and a starting price of $13.6194. Pricing and stock remain time-sensitive, so procurement should verify current availability, authorized-channel status, and volume pricing as of 2026-10-22. This page combines the supplied manufacturer, distributor, and cross-reference evidence with package-specific engineering guidance rather than inferring unsupported specifications.

典型應用
STM32F745IGT6 適用於 7 應用s: Industrial Automation Controller, Communications Gateway, Audio and Digital Signal Processing, Data Acquisition and Measurement, Test and Measurement Instrument, Embedded Power and Motor Control, Secure Networked Embedded System.
Industrial Automation Controller
The STM32F745IGT6 fits an industrial controller that needs a 216 MHz Arm Cortex-M7 core, 1 MB of Flash, and a 176-pin LQFP interface for multiple control and communication signals. Its 32-bit processing platform can support time-critical supervisory logic while integrating peripheral functions on one device. The engineering trade-off is package complexity: a 176-pin LQFP requires disciplined escape routing, manufacturing controls, and careful validation of the exact pin assignments before fabrication.
推薦
Communications Gateway
For a communications gateway, the STM32F745IGT6 combines a 216 MHz 32-bit Cortex-M7 core with 1 MB Flash and a large 176-pin package, providing room for protocol handling, buffering, and multiple external interfaces. The device is a strong fit when firmware size and deterministic processing are priorities. However, the supplied sources do not confirm specific Ethernet, USB, or transceiver peripherals, so interface suitability must be checked against the official STM32F745IG documentation.
推薦
Audio and Digital Signal Processing
The STM32F745IGT6 is a credible candidate for embedded audio or DSP-related control because it provides a 216 MHz Arm Cortex-M7 processor and 1 MB Flash in a 176-LQFP package. The higher clock rate can reduce the processing headroom needed for real-time signal handling compared with a lower-speed general-purpose MCU. Confirm the required DSP peripherals, audio interfaces, memory accessibility, and latency behavior in the exact device documentation before committing the architecture.
推薦
Data Acquisition and Measurement
A data-acquisition system can use the STM32F745IGT6 as a high-speed supervisory and processing controller when a 32-bit Cortex-M7 core, 1 MB Flash, and broad package connectivity are valuable. Its 216 MHz operating rate can support time-sensitive sampling control and data movement, subject to the availability of the required timers, ADC, and DMA resources. Those peripheral details are not present in the supplied snippets and should be verified before assigning acquisition channels.
推薦
Test and Measurement Instrument
The STM32F745IGT6 is suitable for a test-and-measurement controller when the instrument requires a fast 32-bit core, substantial firmware storage, and numerous external control connections. The 176-LQFP package provides access to a broad pin budget, while 1 MB Flash can accommodate embedded control, calibration, and communications code. For precision instruments, verify analog interfaces, timer accuracy, clock sources, low-power behavior, and operating temperature against the manufacturer datasheet.
推薦
Embedded Power and Motor Control
The STM32F745IGT6 can serve as the supervisory controller in a power or motor-control platform when high processing speed and a large pin count simplify integration of control, protection, and communications functions. Its 216 MHz Cortex-M7 core provides substantial real-time compute headroom, while 1 MB Flash supports firmware complexity. The exact timer outputs, analog channels, safety behavior, and control-loop timing are not verified in the supplied data, so engineers should confirm those resources before final control-loop design.
推薦
Secure Networked Embedded System
The STM32F745IGT6 is a candidate for networked embedded equipment that needs a high-performance core and sufficient firmware capacity for protocol stacks and application logic. Its 1 MB Flash and 340 KB RAM provide more storage headroom than small MCUs, while the 176-LQFP package can accommodate extensive board-level connectivity. Exact security peripherals, boot features, protocol support, and lifecycle guarantees must be verified from the manufacturer documentation before making a security claim.

設計說明
Use the official STM32F745IG package drawing as the source of truth for the 176-LQFP footprint. Do not substitute a generic LQFP-176 land pattern without checking body size, pitch, pin numbering, solder-mask clearance, and courtyard dimensions. Route power, ground, clocks, and high-speed signals using the manufacturer's reference recommendations where available, and review the design with the assembly house before release.
Design the 3.3 V supply path only after checking the exact STM32F745IGT6 electrical limits and current requirements in the manufacturer documentation. Provide local decoupling at the device pins, maintain the required supply sequencing, and keep switching-regulator noise away from sensitive analog and communication routes. The supplied data confirms a 3.3 V configuration but does not provide current limits or decoupling values.
Do not treat STM32F746IGT6 as a verified drop-in replacement solely because it appears in the same STM32F7 comparison context. Confirm pin names, alternate functions, memory, peripheral availability, clocking, electrical limits, and firmware device identification before substitution. A same-family relationship can simplify evaluation, but it does not prove that the replacement can be soldered and operated without redesign.
Plan the fine-pitch 176-LQFP assembly early. Validate paste volume, reflow profile, pad geometry, component spacing, test access, and optical inspection requirements. Keep sensitive clocks and communication interfaces away from noisy power conversion stages, and use continuous ground structures where the package and board stackup permit. The 24 x 24 mm package is compact for a 176-pin device but still requires careful escape routing.
