STM32F373CCT6TR - 72MHz Cortex-M4 MCU, 256KB Flash | STMicroelectronics (Tape & Reel)
MPN： STM32F373CCT6TR ✓ 啟用中STM32F373CCT6TR 概覽
A microcontroller is a programmable embedded-control IC that integrates a processor core, memory, peripherals, and communication interfaces on one semiconductor die. The ARM Cortex-M4 core provides deterministic real-time execution, while the STM32F3 family combines digital signal-processing resources with mixed-signal peripherals for industrial instrumentation, motor control, communications, and embedded data acquisition.
The verified device data identifies a 2.0 V to 3.6 V operating range, 72 MHz maximum frequency, 256 KB Flash, 32 KB SRAM, and a 48-pin LQFP package. The Cortex-M4F core supports floating-point calculations, which is useful for control loops and signal-processing workloads. The STM32F373 family also includes four ADCs, three DACs, and two comparators according to the retrieved product and datasheet descriptions.
CAN support provides a practical interface for industrial networking and vehicle-related embedded systems. The manufacturer datasheet search result specifies CAN 2.0A and 2.0B active support with rates up to 1 Mbit/s. This makes the STM32F373CCT6TR suitable for connected sensor nodes, actuator controllers, motor-control subsystems, and compact embedded test equipment.
The 48-LQFP package provides a conventional leaded footprint that can simplify prototype assembly and visual inspection compared with fine-pitch bare die packages. Designers should still follow the manufacturer’s recommended pin assignment, decoupling, clock, and analog-input layout guidance. The ADC and DAC sections require particular attention to analog grounding, reference stability, and separation from high-current switching paths.
This page combines verified STMicroelectronics product information, distributor availability data, package details, interface capabilities, and purchasing guidance. It is intended to help engineers evaluate the STM32F373CCT6TR for embedded control, communications, analog measurement, and real-time signal-processing systems before obtaining the official datasheet and confirming design-specific requirements.

典型應用
STM32F373CCT6TR 適用於 6 應用s: Industrial Sensor and Condition Monitoring, Motor Control and Embedded Automation, CAN-Connected Embedded Control, Precision Analog Signal Acquisition, Audio and Communication Signal Processing, Embedded Test and Measurement Equipment.
Industrial Sensor and Condition Monitoring
The STM32F373CCT6TR fits industrial sensor nodes that must acquire multiple analog measurements and communicate results over a local network. Its four 12/16-bit ADCs provide dedicated conversion resources, while the Cortex-M4F core can execute filtering and control code at up to 72 MHz. The three DACs can generate excitation or test signals, and two comparators support threshold or protection functions. Use the device between sensor conditioning and a CAN 2.0A/B network running up to 1 Mbit/s. Validate analog input ranges, reference accuracy, isolation, and EMC requirements for the deployed environment.
推薦
Motor Control and Embedded Automation
STM32F373CCT6TR is appropriate for compact motor-control and automation modules where fast control computation and analog feedback are needed together. The 72 MHz Cortex-M4F processor supports fixed- and floating-point control algorithms, while four ADCs can sample position, current, and voltage feedback. PWM-capable timers and the comparator resources help implement protection and threshold functions, although the exact timer-channel assignments must be checked in the datasheet. The 48-LQFP package also provides a workable leaded footprint for prototypes and moderate-production assemblies. Gate drivers, isolation, current sensing, and thermal protection remain external design requirements.
推薦
CAN-Connected Embedded Control
The STM32F373CCT6TR is a strong candidate for CAN-connected embedded controllers because the verified manufacturer datasheet search result identifies CAN 2.0A and 2.0B active support with rates up to 1 Mbit/s. A practical design can use the MCU for local filtering, actuator logic, and fault handling while an external CAN transceiver connects the physical bus. The 72 MHz Cortex-M4F core provides useful margin for protocol tasks and deterministic control, and the 256 KB Flash supports a more substantial embedded application than a minimal controller. Validate transceiver logic levels, termination, bus protection, timing, and fault recovery before deployment.
推薦
Precision Analog Signal Acquisition
STM32F373CCT6TR can serve as the digital controller for precision analog signal-acquisition systems because it combines four ADC channels, three DAC channels, two comparators, and a high-performance Cortex-M4F core. The ADCs can acquire sensor or waveform signals, while the DACs support calibration, excitation, or signal reconstruction. A mixed-signal design should keep analog inputs short, controlled impedance traces and away from switching nodes. Use a stable reference and appropriate anti-alias filtering, and confirm ADC input bandwidth and acquisition timing against the manufacturer datasheet. The device is most useful when the application needs local control and data processing without an external DSP.
推薦
Audio and Communication Signal Processing
The STM32F373CCT6TR’s Cortex-M4F architecture, 72 MHz operating frequency, and mixed-signal peripherals make it a candidate for embedded audio and communication signal-processing systems. The FPU supports efficient arithmetic where floating-point operations are useful, while the ADCs and DACs can handle conversion tasks around the digital signal chain. The MCU is not a dedicated high-performance audio codec, so clocking, sampling rate, dynamic range, filtering, and external amplification must be evaluated separately. Use the three DAC outputs and comparator resources only after confirming their pin multiplexing and electrical limits in the exact package datasheet.
推薦
Embedded Test and Measurement Equipment
STM32F373CCT6TR is suitable for compact embedded test and measurement products that need local control, data acquisition, and communication in one device. Four ADCs can support multiple measurement channels, three DACs can provide calibration or stimulus signals, and two comparators can implement threshold tests. The 72 MHz Cortex-M4F core can manage acquisition sequencing, filtering, calibration data, and a user interface while the 256 KB Flash stores application code. The design should define analog input bandwidth, reference stability, grounding, calibration strategy, and communications beforehand. For bench instruments, provide suitable enclosure grounding and isolation where measurements touch high voltage.

設計說明
Design the STM32F373CCT6TR supply around its verified 2.0 V to 3.6 V operating range and place local bypass capacitors close to the device power pins. Keep analog and digital return-current paths controlled, and provide separate filtering for sensitive ADC, DAC, comparator, and clock supplies where the board architecture permits. The supplied data does not specify exact capacitor values or regulator recommendations, so those values must be taken from the manufacturer hardware guidelines rather than inferred here.
Route analog inputs and DAC outputs away from switching nodes, high-current motor-drive paths, and clock edges. Use a continuous ground reference, minimize loop area around sensitive signals, and place ADC filtering or conditioning components near the source. Verify the exact analog pin mapping, alternate-function multiplexing, and package land pattern in the STM32F373CCT6TR datasheet before fabrication. The 48-LQFP package is leaded, but its analog performance still depends on careful board geometry and grounding.
Do not substitute a related STM32F3 MPN solely because its frequency and Flash capacity appear similar. Check the complete pinout, power pins, debug interface, analog functions, timer mappings, memory map, peripherals, and errata for the exact device. The verified search results identify related candidates, but they do not provide enough evidence to establish universal drop-in interchangeability. A hardware review and firmware retest are required for any substitution.
合規資訊
The supplied verified search results identify the manufacturer, device family, package, electrical features, memory, and availability, but do not provide explicit RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification statements for this exact MPN.
