STM32F072CBU7TR - 48MHz Cortex-M0 USB/CAN MCU | STMicroelectronics
Артикул: STM32F072CBU7TR ✓ АктивенSTM32F072CBU7TR Обзор
A microcontroller is a programmable integrated circuit that integrates a processor core, memory, and peripherals into one device. In the product hierarchy, the STM32F072CBU7TR is a microcontroller, which is an embedded processor and a semiconductor. Its Arm Cortex-M0 core provides a 32-bit RISC architecture, while the USB line MCU configuration supports designs that need wired USB connectivity alongside general-purpose embedded control.
The verified configuration provides 128 KB of flash memory, described by the distributor data as 128K x 8, for program storage. Operation reaches 48 MHz, giving designers a higher clock rate than basic Cortex-M0 devices while retaining a simple embedded architecture. The listed supply configuration is 2.5 V/3.3 V, making the MCU suitable for conventional low-voltage embedded systems. USB and CAN are explicitly identified as principal connectivity features of this part.
The 48-UFQFPN package measures 7 x 7 mm and is supplied in tape-and-reel form for automated production assembly. Its small area supports compact PCB layouts, but the fine-pitch package and exposed thermal-pad construction require careful land-pattern, paste-volume, and reflow control. The UFQFPN format also means that PCB design should provide adequate exposed-pad copper and thermal paths rather than treating the bottom pad as an optional connection.
Typical applications include USB-connected data loggers, CAN-connected industrial or automotive peripherals, compact control boards, USB bootloaders, and cost-sensitive embedded systems that need a 48 MHz Cortex-M0 core. For USB designs, the MCU can serve as the protocol controller while an external transceiver provides the physical USB interface. For CAN designs, a dedicated CAN transceiver such as the TCAN334DR can provide the physical bus interface required by STM32F072CBU7TR's CAN capability.
When designing the PCB, verify the exposed-pad soldering requirements and maintain the recommended input, ground, and decoupling layout around the device. Because the verified source data does not provide the complete numbered pin list, engineers should use the manufacturer datasheet and package drawing rather than infer pin assignments from generic 48-pin QFN diagrams.
This product page consolidates verified distributor specifications, price and availability references, interface-focused applications, practical package guidance, and clearly qualified replacement options. It separates confirmed parameters from engineering details that still require confirmation in the manufacturer datasheet, helping designers move from part selection to a robust embedded layout.

Типичное применение
STM32F072CBU7TR подходит для 6 применениеs: USB-Connected Data Logger, CAN Bus Monitoring Module, Compact Industrial Control Board, USB Bootloader and Configuration Tool, USB-to-CAN Embedded Gateway, Cost-Sensitive Embedded Control Product.
USB-Connected Data Logger
The STM32F072CBU7TR fits a USB-connected data logger because it combines a 48 MHz ARM Cortex-M0 core with 128 KB of flash and USB connectivity in a compact 48-UFQFPN package. The MCU can execute acquisition, timestamping, buffering, and USB protocol tasks while the 7 x 7 mm footprint preserves board area. An external USB transceiver and precise decoupling remain necessary. The verified data confirms the USB feature and 2.5 V/3.3 V supply configuration, but the final current budget, clock plan, and USB electrical compliance should be established from the manufacturer datasheet before layout.
Рекомендуется
CAN Bus Monitoring Module
The STM32F072CBU7TR is appropriate for a compact CAN monitoring module because the verified configuration includes CAN connectivity, a 48 MHz Cortex-M0 core, and 128 KB of flash. It can process bus frames, record status events, and expose diagnostics through USB while occupying only a 7 x 7 mm package. A dedicated transceiver such as the TCAN334DR is required for the physical CAN bus. System designers must separately evaluate bus protection, termination, isolation, grounding, and the MCU's exact I/O mapping for their selected board revision.
Рекомендуется
Compact Industrial Control Board
The STM32F072CBU7TR can serve as the central controller on a compact industrial board that handles sensing, local logic, USB maintenance, or CAN-connected remote nodes. Its 48 MHz core provides processing headroom for an embedded-control workload, while 128 KB of flash accommodates application firmware and a bootloader. The 2.5 V/3.3 V operating configuration supports conventional embedded rails. Because the verified snippets do not establish the exact GPIO count, RAM size, or full environmental limits, engineers must confirm those parameters and isolate any hazardous interface through appropriate protection hardware.
Рекомендуется
USB Bootloader and Configuration Tool
The STM32F072CBU7TR is well suited to a USB bootloader or configuration tool because USB connectivity and a 48 MHz Cortex-M0 core are confirmed in the verified Mouser and STMicroelectronics data. The 128 KB flash can hold a bootloader alongside application code, subject to the actual linker map and image sizes. A production implementation should define memory protection, firmware authentication, update recovery, and USB enumeration behavior before implementation. The small UFQFPN package also permits the tool to fit into compact service ports, although fine-pitch assembly and exposed-pad soldering require controlled PCB layout.
Рекомендуется
USB-to-CAN Embedded Gateway
The STM32F072CBU7TR can bridge a USB host to a CAN network by using its verified USB and CAN capabilities alongside the 48 MHz Cortex-M0 processing core. The MCU can maintain protocol state, forward frames, filter messages, and provide configuration diagnostics from a compact 7 x 7 mm footprint. This combination reduces the board area needed for separate interface controllers. Firmware must define buffering, timeout behavior, bus-off recovery, and enumeration, while the PCB should provide transceiver placement, protected interfaces, clean grounding, and tested USB routing.
Рекомендуется
Cost-Sensitive Embedded Control Product
The STM32F072CBU7TR supports compact, cost-sensitive embedded-control products where a 48 MHz ARM Cortex-M0 core, 128 KB flash, USB, and CAN are useful in one device. Consolidating general control and communications requirements can reduce board complexity and simplify firmware integration compared with using separate interface components. The 48-pin UFQFPN package supports compact layouts but requires accurate CAD library data, solder-paste tuning, and adequate exposed-pad thermal copper. Before committing to high-volume production, teams should compare current distributor quotations and confirm long-term availability, since the verified price and inventory snapshots are date-specific.

Заметки по проектированию
Use the exact manufacturer land pattern and exposed-pad geometry for the 48-UFQFPN (7 x 7 mm) package. The exposed thermal pad should be connected according to the STM32F072CB datasheet and PCB library, with enough solder-paste area and vias to control voiding without bridging perimeter pads. A generic QFN-48 footprint should not be substituted solely because both packages have 48 pins, because pad dimensions, pitch, and exposed-pad construction may differ.
Place the local input and bypass capacitors as close as practical to their specified power pins, and provide a clean return path for every supply connection. Although the verified listing identifies a 2.5 V/3.3 V supply configuration, it does not provide the complete decoupling table or regulator sequencing requirements. Use the current manufacturer datasheet to determine capacitor voltage ratings, ESR assumptions, startup behavior, and which pins require external bias rather than estimating those values.
Keep USB and CAN routing away from sensitive analog or high-speed switching paths, while following the transceiver and MCU datasheets for controlled-impedance routing and return paths. USB requires a dedicated external transceiver, and CAN also requires a physical-layer transceiver with suitable protection. Route these interfaces with short return paths to their reference planes and place ESD or surge protection at connector-facing locations, taking care not to add unprotected stubs that degrade signal integrity.
