STM32F745ZET6 - 216MHz Cortex-M7 512KB MCU | STMicroelectronics
MPN： STM32F745ZET6 ✓ 啟用中STM32F745ZET6 概覽
A microcontroller is a programmable integrated circuit that executes firmware, reads sensors, controls actuators, and manages communication interfaces. The STM32F745ZET6 belongs to the STM32F7 family and targets applications requiring a balance of processing speed, memory capacity, graphical or communication capability, and general-purpose embedded control. Its 144-pin LQFP package provides a high pin count for external memory, communications, and mixed-signal connectivity.
Verified product listings identify a 32-bit ARM Cortex-M7 core, 216 MHz maximum operating frequency, and 512 KB Flash memory organized as 512K x 8. Distributor listings also identify the device as an STM32F7 microcontroller with high-performance and DSP/FPU positioning. The 144-LQFP package is supplied in tray packaging according to the verified distributor result. Detailed RAM, peripheral, voltage-range, and environmental specifications are not included in the supplied verified data and therefore are not inferred here.
Typical uses for this MCU include industrial automation equipment, connected control systems, communications equipment, data acquisition, and embedded platforms requiring a fast 32-bit core. The STM32F745ZET6 can serve as the central controller in a product that coordinates real-time inputs, communication protocols, and output devices. Its 216 MHz operating rate provides useful processing headroom for protocol handling and control tasks, while 512 KB Flash supports substantially more firmware than a small microcontroller.
Designers should verify the complete pinout, memory map, clock configuration, power requirements, and peripheral multiplexing against the manufacturer datasheet before PCB release. The 144-pin LQFP footprint requires careful high-speed layout and decoupling practices. Firmware migration between STM32 variants should also account for peripheral differences, clock-tree settings, memory organization, and package-specific pin assignments. This page combines verified distributor specifications, source links, and practical sourcing context rather than reproducing unverified electrical details.

典型應用
STM32F745ZET6 適用於 6 應用s: Industrial Automation Controller, Connected Industrial Control Equipment, Data Acquisition and Signal-Control Systems, Communications Equipment, Embedded Test and Measurement, Power and Motor Control Platform.
Industrial Automation Controller
The STM32F745ZET6 is a strong candidate for industrial automation because its Cortex-M7 core operates up to 216 MHz and provides 512 KB of Flash for control firmware, diagnostics, and communication stacks. The 144-pin LQFP package offers a high pin count for external sensors, actuators, field-bus transceivers, and status interfaces. A production design should still verify the required I/O functions, voltage tolerances, timing, and environmental limits in the manufacturer datasheet.
推薦
Connected Industrial Control Equipment
For connected industrial equipment, the STM32F745ZET6 can combine real-time control with protocol handling and local data acquisition. Its 216 MHz Cortex-M7 processing rate provides headroom for communication stacks and control loops, while 512 KB Flash supports a larger embedded application than a small MCU. The 144-LQFP package helps expose more external connections, but board-level Ethernet, transceiver, and isolation requirements are application-specific.
推薦
Data Acquisition and Signal-Control Systems
The STM32F745ZET6 can serve as the control and communications hub in a data-acquisition system because its Cortex-M7 core supports higher-performance embedded processing and its 512 KB Flash stores acquisition firmware and calibration logic. The 144-pin package can expose external converter, sensor, and communication connections. Exact converter timing, ADC characteristics, input impedance, and signal-integrity requirements are not specified in the supplied verified data and must be checked before implementation.
推薦
Communications Equipment
The STM32F745ZET6 is suitable as a controller in communications equipment requiring a fast 32-bit core and a relatively generous Flash budget. Its 216 MHz operating rate can support protocol processing, supervisory tasks, and real-time control, while the 144-pin LQFP package provides many external signal opportunities. RF transceivers, UART, USB, Ethernet, and other interfaces require exact peripheral and pin verification because those details are not included in the supplied verified data.
推薦
Embedded Test and Measurement
The STM32F745ZET6 can be evaluated for embedded test and measurement front ends where a fast control processor, ample Flash, and many external connections are useful. The Cortex-M7 core can coordinate acquisition, calibration, user-interface logic, and communications, while the 144-pin package supports converters, display interfaces, and control signals. The supplied data does not confirm specialized measurement peripherals or analog accuracy, so the device should be treated as a general-purpose controller pending validation.
推薦
Power and Motor Control Platform
The STM32F745ZET6 is a reasonable platform candidate for power or motor-control systems that need more processing capability and firmware storage than a basic MCU. Its 216 MHz Cortex-M7 core can support supervisory control, current sampling logic, communication tasks, and protection-state handling, while the 144-pin package exposes many control and sensing connections. Power-stage timing, ADC synchronization, protection requirements, and motor-drive qualification must be verified from the complete manufacturer documentation.

主要差異化特點
- High-performance Cortex-M7 processing (對比STM32F407ZGT6TR)
- 512 KB Flash in a 144-LQFP package (對比STM32F103ZET7)
- Related STM32F7 ecosystem (對比STM32F746ZGT6)
- Verified distributor availability context (對比STM32F746ZGT6E)
設計說明
Use the official STM32F745ZE package drawing to define the 144-LQFP footprint before placement. The verified data identifies a 20 mm by 20 mm LQFP package, but it does not provide the complete pin table or recommended land pattern. Confirm pin 1 orientation, lead pitch, solder-mask clearance, and paste stencil geometry against the manufacturer package drawing rather than inferring them from the package name.
Plan the power distribution for 1.8 V, 2.5 V, or 3.3 V operation according to the exact device configuration and the complete manufacturer electrical specifications. Place local decoupling close to the MCU supply pins and keep high-current switching loops away from sensitive signal and reference paths. The supplied data does not specify pin names, capacitor values, or absolute maximum ratings, so those details must come from the datasheet.
Preserve a clean return path for every interface and keep clock, reset, and high-speed communication routes away from noisy switching nodes. The 144-pin package provides many external connections, so a disciplined pin-assignment plan is important. Validate the PCB with the exact STM32F745ZET6 pinout and multiplexing table; the distributor snippets do not provide enough information to reproduce a complete pin assignment.
Estimate board and junction-temperature rise from actual clock, I/O activity, supply voltage, ambient temperature, and package copper exposure. The verified data does not provide thermal resistance or absolute power ratings, so a production thermal calculation cannot be completed from the supplied information. Use the manufacturer thermal data and application-specific worst-case operating mode before defining copper area or thermal relief requirements.
Do not treat a related STM32F7 or STM32F4 MPN as a drop-in replacement solely because it uses a 144-LQFP package. Confirm pin names, alternate functions, power pins, reset behavior, boot configuration, memory size, peripheral compatibility, and firmware support. The alternative entries in this record are candidate references only where the supplied cross-reference data did not establish complete pin-level equivalence.
合規資訊
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred.
