STM32F446RET7TR - 180MHz Cortex-M4 512KB MCU | STMicroelectronics (Tape & Reel)
Référence : STM32F446RET7TR ✗ Fin de vieSTM32F446RET7TR Présentation
A microcontroller is a programmable system-on-chip that integrates a CPU core, nonvolatile program memory, data memory, peripherals, and interface controllers on one die. In the product hierarchy, the STM32F446 belongs to the STM32F4 family of 32-bit microcontrollers and combines an Arm Cortex-M4 processor with embedded-control peripherals. Its 32-bit architecture supports efficient control tasks, while the DSP and FPU features improve performance for common signal-processing workloads.
The verified data establishes a 180 MHz operating frequency, 512 KB organized as 512K by 8 bits of flash, and a 64-LQFP package. The STM32F4 family positioning also identifies the device as a high-performance foundation-line MCU. Detailed RAM size, GPIO count, operating-voltage range, peripheral inventory, temperature range, and electrical limits are not present in the supplied excerpts and therefore remain marked as data needed rather than inferred.
The STM32F446RET7TR can serve as the central controller in industrial equipment where deterministic real-time behavior and floating-point calculations are useful. Its Cortex-M4 DSP and FPU support is relevant to digital filtering, control loops, motion-related computation, and signal conditioning. The 512 KB flash capacity provides room for a substantial embedded application and boot code, although final firmware sizing must be checked against SRAM, bootloader, and peripheral requirements.
A 64-pin LQFP is appropriate for prototypes, instruments, automation controllers, communications equipment, and industrial control boards that need more external pins than a compact QFN package provides. The 10 mm by 10 mm body is larger than the smallest leaded packages, so PCB designers should follow the manufacturer land pattern and allow adequate pin-row clearance during inspection and rework.
When selecting this MCU, engineers should verify the complete pinout, alternate-function mapping, clock tree, memory map, and peripheral electrical limits from the manufacturer datasheet before layout. Firmware development also requires confirming the supported toolchain and debugging interface. Migration to another STM32F4 device should never be based only on package similarity; peripheral functions, pin assignments, clock requirements, and software support must be reviewed explicitly.
This product record consolidates verified distributor specifications, source links, package details, application guidance, and replacement limitations. It also distinguishes confirmed drop-in facts from unverified comparisons so procurement and engineering teams can review current availability, pricing, and technical fit against authoritative documentation.

Applications typiques
STM32F446RET7TR convient pour 6 applications: Industrial Control, Digital Signal Processing, Motor and Motion Control, Medical and Measurement Equipment, Data Acquisition, Communications Equipment.
Industrial Control
The STM32F446RET7TR fits industrial control applications that benefit from its verified 180 MHz Cortex-M4 core, DSP capability, floating-point unit, and 512 KB flash. It can coordinate sensors, actuators, communications, and real-time control logic in one device. The 64-pin LQFP provides a practical leaded footprint for prototypes and production boards where inspectability matters. Before finalizing the design, verify the exact GPIO count, timer assignments, ADC performance, communication peripherals, and operating-temperature limits in the manufacturer documentation. RAM availability must also be checked because it is not stated in the supplied excerpts.
Recommandé
Digital Signal Processing
The Cortex-M4 DSP and floating-point-unit features make the STM32F446RET7TR relevant to embedded filtering, control calculations, and signal-conditioning tasks. Its verified maximum frequency of 180 MHz provides processing headroom for algorithms that do not require a more complex external processor, while 512 KB of flash can hold application code and fixed-point tables. Algorithm suitability depends on cycle count, memory use, and interrupt latency. Because SRAM capacity and detailed timer specifications are absent from the verified excerpts, benchmark the complete firmware and confirm memory availability before committing to this part.
Recommandé
Motor and Motion Control
The STM32F446RET7TR can serve in motor-oriented control prototypes where real-time computation, floating-point operations, and a 64-pin package simplify implementation. The 180 MHz Cortex-M4 core can evaluate control algorithms and manage multiple timing-sensitive tasks, subject to confirmation of the required timers, PWM channels, encoder interfaces, and analog inputs. The supplied excerpts do not verify those peripheral details, so engineers must map them to the exact pinout and electrical limits. Use the manufacturer application guidance for timing, filtering, grounding, and protection rather than extrapolating specifications from another STM32 device.
Recommandé
Medical and Measurement Equipment
The STM32F446RET7TR can be evaluated for compact measurement or medical-instrument electronics when a high-performance control core and substantial 512 KB flash are useful. Arrow's verified listing identifies a 2.5 V or 3.3 V medical-oriented listing context, but it does not provide a medical certification claim. Engineers must review analog front-end interfaces, ADC characteristics, noise behavior, safety requirements, and applicable quality documentation separately. Do not treat marketplace category labeling as evidence of medical qualification; validate the exact ordered part and compliance records before use in regulated equipment.
Recommandé
Data Acquisition
The STM32F446RET7TR is a reasonable MCU candidate for data-acquisition front ends where control firmware must coordinate sampling, buffering, communications, and host connectivity. Its 180 MHz processing rate and DSP/FPU support can help manage numerical work around external converters, while 512 KB flash accommodates firmware and configuration. The 64-pin LQFP is useful when a design needs externally accessible signals or test points. Verify ADC characteristics, DMA resources, memory capacity, communication peripherals, and package pin multiplexing in the official datasheet; none of those detailed resource counts are confirmed by the supplied snippets.
Recommandé
Communications Equipment
The STM32F446RET7TR can support embedded communications equipment when the required protocol interfaces, processing margin, and memory budget fit the device. Its 180 MHz Cortex-M4 core and DSP/FPU support are useful for framing, buffer management, signal conditioning, and protocol processing, while the LQFP package simplifies prototype access. However, the verified excerpts do not list UART, USB, Ethernet, CAN, or other peripheral configurations. Engineers must check the exact alternate-function mapping and pin conflicts in the official datasheet, then validate firmware drivers and timing against the intended industrial or networking environment.

Notes de conception
Use the current STMicroelectronics land pattern for the 64-pin, 10 mm by 10 mm LQFP and verify all terminal assignments before routing. Confirm power and ground connectivity, decoupling, reset, clock, boot configuration, and debug access against the full manufacturer documentation. The search excerpts do not provide a verified terminal map, so do not infer connections from another STM32F4 model.
Design the supply network for the device's verified 2.5 V or 3.3 V operating context while checking the exact electrical limits and voltage sequence in the manufacturer datasheet. Place required bypass capacitors close to the relevant supply pins and provide clean return paths. Because regulator tolerances, transient limits, and current consumption are not supplied, select those values from the official electrical characteristics rather than estimating them.
Do not assume that any similar STM32F4 MPN is electrically or pin-compatible. Compare the exact orderable suffix, package drawing, memory configuration, peripheral set, clock limits, temperature range, and qualification status. Firmware porting also requires reviewing startup files, linker memory definitions, pin configuration, and peripheral instances; physical package equality alone does not establish a safe drop-in replacement.
Preserve short return paths and isolate clocks, sensitive analog inputs, and high-speed communications from noisy switching paths. Route decoupling connections directly to the intended pins, keep test points accessible, and check the assembly capability for the 10 mm LQFP body. Follow the manufacturer recommended layout and EMC guidance for the final peripheral mix because the supplied excerpts do not identify the complete interface set.
Informations de conformité
The supplied excerpts do not provide verified compliance declarations or qualification status. Marketplace category wording, including the Arrow medical listing, is not treated as evidence of compliance or certification.
