STM32F765IIT7 - 216MHz Cortex-M7 2MB MCU | STMicroelectronics
料号： STM32F765IIT7 ✓ 量产中STM32F765IIT7 概述
A microcontroller is a programmable semiconductor that integrates a processor core, nonvolatile program memory, data memory, peripherals, and interface controllers on one device. The STM32F765 belongs to the STM32F7 high-performance microcontroller family, where the ARM Cortex-M7 core sits within the broader embedded MCU and semiconductor hierarchy. Its 32-bit architecture supports efficient control, communications, and digital signal-processing workloads, while integrated peripherals reduce the component count required in industrial and embedded products.
The verified product information identifies a 216 MHz operating speed and 2 MB Flash capacity. The manufacturer product page also confirms that the STM32F765 device family uses the Arm Cortex-M7 32-bit RISC core and can operate at up to 216 MHz. Available family information identifies the STM32F765, STM32F767, STM32F768Ax, and STM32F769xx devices as members of the same high-performance Cortex-M7 platform. Detailed RAM, operating-voltage, peripheral, and thermal limits were not included in the supplied verified excerpts.
The STM32F765IIT7 combines a 216 MHz Cortex-M7 processor with 2 MB of embedded Flash in a 176-LQFP package. Its large pin count supports the broad pin-oriented interface mix associated with high-performance STM32 devices, including communication, timing, analog-control, and general-purpose I/O functions. The exact pin assignments, alternate functions, exposed programming pins, and ground distribution must be taken from the official STM32F765-series datasheet before PCB routing or schematic capture is released.
Typical uses include industrial controllers, factory automation equipment, communications gateways, motor-control systems, test and measurement instruments, and embedded signal-processing products. The Cortex-M7 execution rate is useful for protocol handling, real-time control loops, and DSP-assisted filtering. Designers should still budget processing margin for interrupts, graphics or communications stacks, and safety monitoring rather than treating the stated 216 MHz maximum as sustained application performance.
For new hardware, verify the complete STM32F765II datasheet, pin alternate-function matrix, memory map, power-consumption characteristics, and package tolerances before layout. Firmware development also depends on the selected toolchain, debugger, boot configuration, clock tree, and peripheral initialization library. The STM32F765IIT7 is supplied in a tray according to the verified distributor description, and the listed LCSC starting price was $21.8836 as of 2026-10-28.
This product record combines the verified manufacturer specifications, distributor availability references, package details, and same-footprint comparison candidates. It also adds engineering-focused selection guidance, application context, and procurement information to provide more decision support than a basic distributor listing alone.

典型应用
STM32F765IIT7 适用于 6 应用s: Industrial Automation Controllers, Motor Control and DSP, Communications Gateways, Test and Measurement Equipment, Embedded Graphical User Interfaces, Medical and Monitoring Systems.
Industrial Automation Controllers
The STM32F765IIT7 fits industrial automation controllers that combine real-time I/O control with protocol handling and signal processing. Its Cortex-M7 core operates at up to 216 MHz, while 2 MB of Flash provides room for substantial control firmware, diagnostics, parameter tables, and communication stacks. The 176-LQFP package exposes a broad pin-oriented interface for sensors, actuators, communications, and discrete digital I/O. A system architect should reserve the device for controllers that need more compute margin than an entry-level Cortex-M MCU while retaining a single-chip solution. Review clocking, pin multiplexing, ADC characteristics, and peripheral assignment from the manufacturer datasheet before committing the 24 x 24 mm land pattern.
推荐
Motor Control and DSP
The STM32F765IIT7 is suitable for advanced motor-control and DSP-assisted products because its ARM Cortex-M7 core combines a 216 MHz maximum clock with DSP and floating-point capabilities. This provides computational headroom for current and speed loops, transformations, filtering, and real-time fault handling. The 2 MB Flash capacity allows more elaborate control algorithms and parameter storage than a 512 KB-class MCU. Use the device for digitally controlled motors, power converters, and industrial motion modules where control timing and signal-processing workload are significant. The exact PWM, timer, ADC, and synchronization resources must be confirmed against the STM32F765-series datasheet, including trigger latency and pin availability on the selected LQFP variant.
推荐
Communications Gateways
STM32F765IIT7 can serve as the processing core of a communications gateway or protocol-concentrator that must manage serial traffic, local control, and data buffering. Its 216 MHz Cortex-M7 performance is useful when Ethernet, fieldbus, or wireless-control software must coexist with application logic. The 2 MB Flash supports larger protocol stacks and configuration firmware, while the 176-LQFP package offers many externally routed signals for communications and status interfaces. Designers should evaluate the exact peripheral mix, DMA channels, memory configuration, and clock tree for the required protocol rather than assuming all STM32F7 devices provide identical connectivity. Low-power modes and peripheral clock behavior also require direct verification from the manufacturer documentation.
推荐
Test and Measurement Equipment
The STM32F765IIT7 fits test and measurement instruments that require deterministic control, data acquisition, display or communications management, and embedded DSP. The 216 MHz Cortex-M7 core can process control algorithms and measurement data while the 2 MB Flash stores firmware and calibration data. Its 176-pin LQFP package supports access to a broad set of digital, analog, timer, and communications resources. Potential uses include automated test equipment, data loggers, laboratory controllers, and portable analyzers. Engineers should confirm ADC accuracy, DAC availability, timer resolution, memory bandwidth, and peripheral pin multiplexing because the supplied verified excerpts do not provide those detailed limits. PCB layout should also account for analog grounding, clock jitter, and high-speed signal return paths.
推荐
Embedded Graphical User Interfaces
STM32F765IIT7 is applicable to embedded human-machine interfaces that combine graphics with responsive control functions. Its 216 MHz Cortex-M7 core provides more performance headroom than the Cortex-M4-class alternatives identified in the verified comparisons, and 2 MB of Flash can hold interface firmware, fonts, graphics, and application logic. The large 176-LQFP package can support display, touch, storage, and communications interfaces. It is most useful where the display workload, network protocol, and control loop must coexist on one MCU. Before schematic capture, verify whether the selected device includes the required display or LCD interfaces, sufficient external-memory interfaces, and the required GPIO count; those details were not present in the supplied excerpts and must be checked in the official STM32F765 datasheet.
推荐
Medical and Monitoring Systems
The STM32F765IIT7 can support monitoring and diagnostic equipment where a high-performance embedded processor handles acquisition control, signal analysis, communications, and user interaction. Its 216 MHz Cortex-M7 rating and DSP/FPU capability are useful for filtering and real-time algorithms, while the 2 MB Flash supports larger firmware than 512 KB-class devices. The 176-LQFP package provides extensive routing options for sensors, displays, storage, and communications. Medical use requires additional system-level qualification, electrical-safety analysis, and validation of every relevant peripheral characteristic; RoHS and REACH compliance do not by themselves constitute medical certification. Firmware partitioning, watchdog behavior, fault containment, and traceability should be evaluated before using this MCU in a safety-relevant monitoring function.

设计说明
Route the STM32F765IIT7 power, ground, clock, and high-speed interface nets using the STM32F765II package and layout guidance in the manufacturer documentation. The 176-LQFP footprint has closely spaced leads, so use a fabrication stack-up capable of the package geometry and place decoupling capacitors at each supply pin group. Do not infer the exposed-pad or thermal-land arrangement from a generic LQFP library because the supplied excerpts do not establish whether this variant uses one.
Provide separate filtering and decoupling paths for the MCU supply domains rather than relying on a single unpartitioned rail connection. The verified range of 1.8 V to 3.6 V does not establish each domain's exact operating point, regulator accuracy, startup sequence, or current budget. Those limits must be extracted from the official datasheet before selecting external regulators, capacitors, and power switches.
Keep the main clock routing short, continuous, and away from switching-converter nodes and high-current outputs. If an external oscillator is used, validate its required amplitude, load capacitance, startup time, and jitter against the STM32F765 electrical characteristics. The supplied data confirms a maximum 216 MHz core frequency but does not provide the clock-tree or timing tables needed for a complete signal-integrity budget.
Do not substitute a same-package STM32F7 device solely from its order code. Pin multiplexing, peripheral availability, flash organization, RAM, clock limits, and firmware startup support can differ even when the package is identical. For every alternative listed here, compare the official datasheet pin table, electrical limits, memory map, and errata before approving it as a drop-in production alternative.
