STM32F071RBT6 - 48MHz Cortex-M0 128KB MCU | STMicroelectronics
MPN: STM32F071RBT6 ✓ AktifSTM32F071RBT6 Ringkasan
A microcontroller is a programmable system-on-chip that integrates a CPU core, program memory, data memory, peripheral interfaces and clock circuitry on one package. The STM32F071 is positioned within the STM32F0 access-line hierarchy, where Arm Cortex-M0 instruction-set compatibility and a compact pin count balance firmware simplicity with useful mixed-signal and connectivity capabilities.
The verified device data identifies a 48 MHz maximum operating frequency, 128 KB of Flash organized as 128K x 8, and 16 KB of SRAM. Its 51 available I/O pins support connections to sensors, actuators, human-interface devices and external memory. The 64-LQFP package exposes these connections on a conventional 0.5 mm-pitch footprint while retaining thermal copper and soldering accessibility that is useful for hand-soldered prototypes and moderate-cost production boards.
STM32F071 devices are appropriate for motor and power-system controllers, compact sensor hubs, HVAC controls, security panels and small user-interface subsystems. Their Arm Cortex-M0 core supports a common embedded software ecosystem that can be adapted across several STM32 families, while the 48 MHz clock rate provides useful headroom for interrupt-driven control loops, protocol handling and modest graphical interfaces.
When laying out the board, allocate decoupling capacitors close to the supply pins and provide a stable clock source according to the manufacturer reference design. Confirm that every external peripheral voltage, level-shifting requirement and USB or communications interface matches the selected STM32F071 variant before releasing the PCB.

Aplikasi Umum
STM32F071RBT6 cocok untuk 6 aplikasis: Compact Industrial Control Panel, Motor and Power-System Controller, Environmental Sensor Hub, Battery-Powered Monitoring Device, User Interface and Access Controller, Cost-Sensitive Consumer Controller.
Compact Industrial Control Panel
The STM32F071RBT6 fits a compact control panel that scans buttons, drives indicators and manages a small motor or relay. Its 48 MHz Arm Cortex-M0 core provides sufficient execution headroom for interrupt-driven control, debouncing and communication tasks, while 128 KB Flash accommodates an RTOS-based application or a substantial bare-metal firmware image. The 51 I/O pins reduce the need for I/O expanders, and the 64-LQFP package remains accessible for prototype soldering and low- to medium-volume assembly.

Motor and Power-System Controller
The STM32F071RBT6 is appropriate for supervisory control in a motor-drive or power-management subsystem where a 48 MHz Cortex-M0 core handles timing, protection logic and communication. Its 128 KB Flash is suitable for state machines, fault logging and parameter tables, while the 51 available I/O pins allow connection of gate-driver interfaces, current sensing, fault signals and contactors. Designers must verify analog and switching-node limitations in the datasheet and keep high-current paths separate from the MCU ground reference.
Direkomendasikan
Environmental Sensor Hub
The STM32F071RBT6 can collect readings from temperature, humidity, pressure and air-quality sensors while conditioning the data for a local display or network uplink. Its 51 I/O pins allow multiple digital buses and discrete alarm inputs without an expander, and its 128 KB Flash is practical for calibration tables, filtering code and communication stacks. Selection of external sensors should account for the MCU's verified electrical limits, and sensor grounds should be connected using a layout that minimizes interference with the Cortex-M0 supply rail.
Direkomendasikan
Battery-Powered Monitoring Device
The STM32F071RBT6 supports compact battery-powered monitors that combine periodic sensing, local status indication and low-rate communications. Its 128 KB Flash provides room for event buffers and protocol handlers, while the 51 I/O pins leave room for wake-up sensing and charger-status inputs. Because the supplied data does not include sleep-current or operating-voltage figures, a battery design must consult the manufacturer datasheet for low-power modes, regulator choice and startup timing before estimating service life.
Direkomendasikan
User Interface and Access Controller
The STM32F071RBT6 can manage a keypad, display, status LEDs and access-control outputs on a single 64-LQFP device. Its 48 MHz core supports debouncing, menu state handling and serial display updates, while the 51 I/O pins accommodate row scanning, indicators, latch outputs and communications. The package's 0.5 mm pitch is manageable in standard assembly, but exposed-pad layout, signal integrity and firmware peripheral assignment must follow the STMicroelectronics layout guidance.
Direkomendasikan
Cost-Sensitive Consumer Controller
The STM32F071RBT6 is a practical choice for compact consumer products that need more control capability than a basic 8-bit device but do not require USB. The 48 MHz Arm Cortex-M0 core and 128 KB Flash support protocol handling, LED effects, touch-style keypad scanning and local configuration, while the 64-LQFP package simplifies assembly. Product teams should confirm the required interface set and environmental tests, since the verified data confirms core performance and memory but does not establish USB capability.

Diferensiator Kunci
- Verified 48 MHz Cortex-M0 performance with 128 KB Flash (vsSTM32F091RBT6)
- Access-line positioning avoids an unnecessary USB-line substitution (vsSTM32F072RBT6)
- Compact 64-LQFP implementation with 51 I/O pins (vsSTM32F073RBT6)
Catatan Desain
Place the required local decoupling capacitors immediately across the device supply and ground pins, with the shortest possible loop area. Verify the exact supply-voltage limits and decoupling values in the STM32F071x8/xB datasheet because those details were not included in the supplied verified dataset. If the board also powers motors or relays, separate high-current return paths from the MCU ground and validate startup behavior during the maximum load transient.
The 64-LQFP footprint is 10 mm x 10 mm and should be laid out with the manufacturer's recommended pad dimensions and exposed-pad treatment. Keep the 0.5 mm-pitch perimeter routing clear of assembly bridges, and preserve access for inspection or rework. Follow the device's debug, boot and clock pin recommendations so that programming and crystal or clock-source options remain usable after population.
Route the oscillator and sensitive analog inputs away from fast digital nets and switching-node copper. If the design uses communication lines such as CAN or RS-485, terminate and isolate them according to the chosen transceiver rather than treating them as direct MCU signals. The supplied data confirms 51 I/O pins but not the complete alternate-function matrix, so assign every peripheral signal from the official datasheet pin table.
Do not treat a similar STM32F0 package as proof of a zero-change substitution. STM32F072RBT6, STM32F073RBT6 and STM32F091RBT6 may alter USB, CEC or other peripheral resources, and firmware driver assumptions can fail even when the footprint matches. Build a substitution checklist covering package drawing, supply voltage, I/O mapping, clock tree, interrupt vector, bootloader, debug and peripheral configuration.
Informasi Konformitas
The supplied verified web dataset confirms device specifications and distributor availability but does not include explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free or conflict-minerals statements. These fields therefore remain unknown rather than being inferred.
