STM32F071CBT6 - 48MHz Cortex-M0 MCU | STMicroelectronics
MPN: STM32F071CBT6 ✓ AktifSTM32F071CBT6 Ringkasan
A microcontroller is a programmable integrated circuit that combines a processor core, memory, peripherals, and interfaces on one device. The STM32F071CBT6 belongs to the STM32F0 access-line hierarchy, where the Arm Cortex-M0 processor core sits beneath the STM32 family and the broader category of general-purpose embedded processors. Its combination of 128 KB Flash, 16 KB SRAM, and analog conversion resources supports both control logic and low-speed signal acquisition without requiring separate analog converters.
The 48 MHz Cortex-M0 core provides deterministic processing for real-time control loops, while the CRC calculation unit supports data-integrity checks in communications and storage systems. The device includes seven general-purpose 16-bit timers, one 32-bit timer, and an advanced-control timer, allowing designers to allocate timer resources among periodic scheduling, input capture, output compare, motor control, or PWM generation. The integrated ADC and DAC support analog monitoring and controlled analog outputs within the same 2.0 V to 3.6 V supply domain.
Communication and peripheral integration reduces the component count in embedded systems that need serial data exchange or dedicated control outputs. The verified manufacturer material identifies a CRC calculation unit, reset and power management, one 12-bit ADC, a two-channel 12-bit DAC, and multiple communication interfaces. These resources make the STM32F071CBT6 suitable for compact industrial controllers, instrumentation, consumer peripherals, and low-to-medium-speed motor-control equipment where a larger Cortex-M processor would add unnecessary cost or complexity.
The 48-pin LQFP package provides a conventional surface-mount footprint with accessible leads for assembly and inspection. A 7x7 mm body preserves board area in space-constrained equipment, while the exposed thermal strategy and lead geometry support manufacturing processes that can inspect individual connections. Because this is a digital mixed-signal microcontroller rather than a discrete power semiconductor, its SOA field is not applicable.
Designers should verify every peripheral assignment, alternate-function mapping, pin electrical limit, clock configuration, and decoupling requirement against the STM32F071x8/STM32F071xB manufacturer datasheet before schematic release. The 2.0 V to 3.6 V operating range and 48 MHz core frequency must be considered together when selecting external components and defining the power architecture.
This page combines verified manufacturer and distributor information with a focused selection guide, package-level comparison, and application engineering notes. It also distinguishes same-package family alternatives from broader functional substitutes, helping engineers identify replacements without overlooking peripheral differences, firmware constraints, or qualification requirements.

Aplikasi Umum
STM32F071CBT6 cocok untuk 6 aplikasis: Industrial Sensor and Condition Monitoring, Compact Motor and PWM Control, Low-Rate Serial Communications Controller, Precision Analog Control System, Consumer Accessory and User Interface, Data Acquisition and Embedded Logging.
Industrial Sensor and Condition Monitoring
The STM32F071CBT6 fits compact condition-monitoring equipment because it combines a 48 MHz Cortex-M0 core, 128 KB Flash, and 16 KB SRAM with an integrated 12-bit ADC. The MCU can sample analog inputs, apply digital filtering, evaluate thresholds, and retain operating data without requiring a separate converter. Its 2.0 V to 3.6 V supply range simplifies integration around 3.3 V sensor systems. The twelve timers can support periodic sampling, elapsed-time measurement, and sensor-specific timing. Designers should use the manufacturer datasheet to confirm ADC accuracy, sampling requirements, channel availability, and pin multiplexing before fixing the analog front end.

Compact Motor and PWM Control
The STM32F071CBT6 is appropriate for small motor-control and PWM systems because its 48 MHz Cortex-M0 core can execute control calculations while the integrated timers generate precisely timed PWM signals. The device includes seven general-purpose 16-bit timers, one 32-bit timer, and an advanced-control timer, providing more timer allocation than a basic microcontroller. Its 128 KB Flash supports control code, parameter storage, and fault-handling routines, while the 16 KB SRAM accommodates working state. Power-stage sizing and thermal analysis remain external design responsibilities; motor current must not be applied directly to the microcontroller pins.

Low-Rate Serial Communications Controller
The STM32F071CBT6 can serve as a compact communications controller because the STM32F0 family combines an Arm Cortex-M0 processor with multiple serial interfaces and a hardware CRC calculation unit. The 48 MHz core provides useful margin for frame handling, protocol checks, and supervisory logic, while 128 KB Flash accommodates protocol tables and application firmware. The CRC engine can accelerate integrity checks on transmitted or received data. Exact UART, SPI, and I2C configurations must be confirmed against the manufacturer datasheet because the verified snippets identify the interface category without listing every peripheral variant.

Precision Analog Control System
The STM32F071CBT6 is suitable for compact closed-loop analog control because it integrates a 12-bit ADC, a two-channel 12-bit DAC, and twelve timers. The ADC can monitor a control variable, the DAC can generate reference or actuator commands, and timer outputs can synchronize the sampling sequence. Its 48 MHz Cortex-M0 core can execute proportional-integral-derivative control and filtering, while 128 KB Flash and 16 KB SRAM provide adequate storage and working memory for many embedded loops. Engineers should verify conversion timing, output range, DAC output buffer behavior, and analog-pin multiplexing in the manufacturer datasheet.

Consumer Accessory and User Interface
The STM32F071CBT6 fits compact consumer accessories where an inexpensive 48-pin microcontroller must manage buttons, indicators, sensors, and serial data. Its 128 KB Flash supports a user interface and communication stack, while the integrated ADC and DAC can support analog controls or simple signal generation without separate mixed-signal devices. The 7x7 mm LQFP package reduces board footprint relative to larger leaded packages, and the 2.0 V to 3.6 V operating range works with common low-voltage power systems. Production firmware must still be reviewed for bootloader, upgrade, and peripheral assignments before release.

Data Acquisition and Embedded Logging
The STM32F071CBT6 can implement compact data-acquisition and logging systems by combining a 12-bit ADC with 128 KB Flash and 16 KB SRAM. The processor can sample inputs according to timer events, perform digital processing, and buffer results before transmitting them through one of the STM32F0 communication peripherals. Hardware CRC support can help verify stored or transmitted records. Its 48-pin LQFP package exposes the required mixed-signal and serial functions in a conventional surface-mount format. For designs requiring extensive local storage, an external nonvolatile memory device and verified bus-level timing should be added rather than relying on the internal Flash alone.

Diferensiator Kunci
- Higher memory capacity than the 64 KB Flash family alternatives (vsSTM32F071C8T6)

- Verified integrated two-channel DAC in the target device (vsSTM32F070CBT6)
Catatan Desain
Design the supply rail for the verified 2.0 V to 3.6 V digital and I/O range and place the manufacturer's recommended decoupling capacitors at the VDD and VSS pins. Keep analog and digital return-current paths controlled because the ADC and DAC are integrated into the same mixed-signal device. Exact capacitor values, analog supply relationships, and power-current limits are not present in the supplied excerpts, so they must be taken from the official STM32F071x8/STM32F071xB manufacturer datasheet rather than estimated.
Assign pins from the official STM32F071CBT6 pin table before routing the PCB, especially for SWD debugging, clock inputs, analog channels, and alternate-function signals. The part is a 48-pin LQFP, so lead spacing and courtyard dimensions must be based on the exact 7x7 mm package drawing. Do not use a generic 48-pin footprint without checking whether its exposed-pad or thermal-pad treatment matches the selected package variant.
A same-package STM32F0 device is not automatically a functional drop-in replacement. Verify the Flash size, SRAM capacity, ADC and DAC availability, timer channels, clock tree, communication peripherals, boot configuration, and package-specific pin functions. In particular, STM32F071C8T6 and STM32F072C8T6 have 64 KB Flash rather than the target's 128 KB, so either part can fail to accept existing firmware even when its footprint is unchanged.
Informasi Konformitas
The supplied verified excerpts do not explicitly state the target's RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status. AEC-Q100 is marked not_applicable because this industrial and consumer MCU is not presented as an automotive-qualified variant, but compliance declarations remain unknown.
