STM32F072RBT7TR - 48MHz Cortex-M0 128KB MCU | STMicroelectronics (Tape & Reel)
料号： STM32F072RBT7TR ✓ 量产中STM32F072RBT7TR 概述
A microcontroller is a semiconductor device that integrates a processor core, program memory, data memory, peripherals, and I/O into one embedded-control platform. The STM32F0 series belongs to the ARM Cortex-M microcontroller hierarchy and combines a low-complexity 32-bit instruction set with dedicated communication and timing peripherals. This makes the STM32F072RBT7TR suitable for systems that need deterministic control without a higher-performance application processor.
The STM32F072RBT7TR combines a 48 MHz ARM Cortex-M0 core with 128 KB of Flash. Verified distributor records also identify USB and CAN connectivity, which can reduce the need for external interface controllers in connected equipment. Its 64-LQFP package provides 64 physical pins and is suitable for through-hole assembly or mixed-technology PCB layouts where a fine-pitch BGA package would be unnecessary.
The available evidence confirms a mainstream STM32F0-series product with USB and CAN support, 128 KB Flash, and operation up to 48 MHz. Detailed peripheral assignments, SRAM capacity, voltage limits, pin functions, bootloader behavior, and electrical timing values are not included in the supplied verified data. Those parameters must be confirmed in the manufacturer datasheet before final schematic or firmware release.
Typical uses include USB-connected control accessories, CAN-based industrial nodes, compact motor and actuator controllers, sensor-hub boards, and general embedded products where a 32-bit ARM Cortex-M0 MCU is sufficient. The 64-LQFP package is particularly useful when production teams prefer visible solder joints and straightforward inspection.
The main design consideration is interface assignment. USB, CAN, oscillators, reset, programming pins, and general-purpose I/O must be mapped against the manufacturer pinout and application requirements before PCB routing. Firmware support, clock configuration, transceiver requirements, and USB or CAN bus protection are outside the supplied data and should be verified against the official documentation.
This page consolidates verified manufacturer and distributor information, technical search coverage, pricing context, and design-oriented interpretation. It does not infer undocumented electrical values, and it distinguishes confirmed specifications from data that still requires engineer verification.

典型应用
STM32F072RBT7TR 适用于 6 应用s: USB-Connected Control Accessory, CAN-Based Industrial Control Node, Sensor Hub and Data Logger, Compact Motor and Actuator Controller, Human-Interface Control Panel, USB-to-CAN Embedded Gateway.
USB-Connected Control Accessory
STM32F072RBT7TR fits a USB-connected controller when the product needs a 48 MHz 32-bit Cortex-M0 core, 128 KB embedded Flash, and integrated USB support. The MCU can manage buttons, indicators, sensors, and local control logic while communicating with a host over USB, reducing the need for a separate USB controller. Its 64-LQFP package also leaves leads accessible for visual inspection and mixed assembly. The engineering trade-off is that USB physical-layer support, connector protection, firmware classes, and exact signal assignments must be confirmed from the official datasheet before routing the board.
推荐
CAN-Based Industrial Control Node
STM32F072RBT7TR is appropriate for a compact CAN node because verified distributor data identifies CAN support alongside the 48 MHz ARM Cortex-M0 core and 128 KB Flash. The device can execute application logic, monitor digital or analog inputs, and manage actuator commands while sharing bus traffic with other equipment. A practical design still needs a CAN transceiver, termination where required, surge protection, and firmware that matches the selected CAN hardware. Because the supplied data does not enumerate GPIO mappings or electrical limits, those details must be verified from STMicroelectronics documentation before schematic approval.
推荐
Sensor Hub and Data Logger
The STM32F072RBT7TR can serve as the central controller in a small sensor hub when its 128 KB Flash capacity is sufficient for application firmware, data buffering, and USB export. A 48 MHz Cortex-M0 core provides a practical platform for periodic sampling, filtering, status handling, and communications scheduling in a non-real-time embedded system. The 64-LQFP package provides ample physical pins compared with smaller leadless packages, helping separate communication, programming, and sensing functions. SRAM capacity and exact ADC specifications are not supplied, so data-rate and buffer sizing require confirmation before firmware architecture is finalized.
推荐
Compact Motor and Actuator Controller
STM32F072RBT7TR is suitable for compact motor or actuator control when the application does not require the processing headroom of a higher MCU family. The 48 MHz Cortex-M0 core can execute control tasks, while 128 KB Flash provides room for embedded control logic and USB or CAN communication services. Its 64-pin LQFP package offers more routing flexibility than many small packages and remains inspectable after soldering. The MCU alone is not a motor driver: power transistors, gate drivers, current sensing, protection, and functional-safety review remain necessary, and those parameters are outside the supplied evidence.
推荐
Human-Interface Control Panel
STM32F072RBT7TR can support a human-interface panel that combines buttons, LEDs, displays, and USB configuration. The 48 MHz ARM Cortex-M0 processor provides enough execution capability for event handling and communications, while the 128 KB Flash store can hold firmware and fixed UI logic. A 64-LQFP package is advantageous when a panel needs many discrete I/O connections and production teams prefer leads that can be visually inspected. USB support is confirmed by the verified distributor data, although connector implementation, display interface assignments, debounce strategy, and pin multiplexing must be checked in the official pinout.
推荐
USB-to-CAN Embedded Gateway
STM32F072RBT7TR is a logical candidate for a small USB-to-CAN gateway because both interfaces are named in the verified distributor description. The MCU can bridge host commands and industrial bus traffic while adding local logic, status reporting, or configuration storage. This integration reduces board area compared with a design that uses a separate USB interface MCU and CAN interface MCU. Real deployment still requires correctly selected transceivers, bus protection, ground strategy, firmware protocol handling, and timing analysis. The supplied data does not confirm transceiver integration or maximum bus rates, so those details must come from the manufacturer datasheet.

设计说明
Treat the 64-LQFP footprint and every alternate-function assignment as controlled interfaces. Verify programming, reset, clock, USB, CAN, ground, and supply pins against the official STM32F072RB documentation before schematic release. The verified data does not enumerate the pinout, so no lead function should be assigned from memory. Also preserve exposed copper and thermal-relief patterns specified for the selected package.
Separate digital, analog, and communication-supply decisions until the manufacturer voltage and decoupling requirements are available. The distributor snippets establish a 2.5 V / 3.3 V context but do not provide operating-voltage tolerances, current limits, or recommended capacitance. Do not size USB or CAN interface power paths from those snippets alone; use the official datasheet and transceiver specifications for static and transient headroom.
USB and CAN are high-integrity interfaces even when the MCU itself is the target. Keep clock and decoupling layout compact, provide a clean return path, and separate switching nodes from communication traces. CAN requires attention to bus topology and termination, while USB requires geometry and return-path continuity. Exact rise-time, impedance, and timing values are not present in the supplied data and must be derived from the final interface and component selections.
合规信息
The supplied verified snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is shown as unknown rather than not_applicable because the automotive qualification status was not supplied.
