STM32F058R8T6 - 48MHz Cortex-M0 64KB MCU | STMicroelectronics
MPN: STM32F058R8T6 ✓ ActiveSTM32F058R8T6 Overview
A microcontroller is a programmable semiconductor that integrates a CPU core, Flash program memory, SRAM, peripherals, and interface controllers on one package. Within the product hierarchy, the STM32F058R8T6 is an ARM Cortex-M0 microcontroller, an embedded processor, a 32-bit microcontroller, and ultimately a general-purpose semiconductor used for real-time control, communication, and monitoring functions.
The verified headline characteristics are a 48 MHz maximum CPU frequency, 64 KB of Flash organized as 64K by 8 bits, and 32-bit ARM Cortex-M0 processing. The device is identified as a low-voltage-line MCU supporting 1.8 V operation, while distributor documentation also describes 2.5 V and 3.3 V operating conditions. Its 64-pin LQFP package provides a substantial pin count for mixed-signal, communication, and general-purpose embedded-control designs.
The STM32F0 architecture is positioned for low-cost, low-power embedded applications where deterministic control and a broad peripheral set matter more than high processor throughput. A 48 MHz Cortex-M0 core is suitable for supervisory loops, protocol handling, sensor acquisition, and user-interface control. Because detailed SRAM, peripheral, timer, and converter specifications are not present in the supplied source data, those values are intentionally not inferred here.
Typical design uses include industrial control nodes, low-voltage embedded systems, motor-control loops, communications modules, and compact consumer products. The 64-LQFP format is particularly useful when a design requires more external signal access than a small QFN package provides. Applications should still be qualified against the complete manufacturer datasheet for electrical limits, clock configuration, peripheral behavior, and environmental requirements.
The principal design consideration is that a package match alone does not guarantee firmware interchangeability. Board designers must verify power rails, oscillator connections, peripheral mappings, boot configuration, programming interface, and pin multiplexing before substituting an STM32F058-family device. The temperature grade must also match the product's environmental requirements rather than only its footprint.
This product record consolidates verified distributor pricing, package information, temperature-range data, and same-family drop-in candidates into an engineering-oriented reference. It also distinguishes confirmed specifications from missing technical data, helping procurement and hardware teams assess sourcing options without confusing an LQFP footprint match with full functional equivalence.

LIN-Connected Industrial Control Nodes
The STM32F058R8T6 fits LIN-connected control nodes because its 48 MHz ARM Cortex-M0 core provides more than enough performance for supervisory control, periodic sensor handling, and communication servicing. Its 64 KB of Flash supports compact embedded firmware, while the 64-LQFP package offers a broad selection of external pins for a controller, actuators, and status signals. The verified -40 °C to +85 °C range covers many indoor industrial environments. Before deployment, engineers should verify the complete LIN transceiver arrangement, timing budget, regulator margin, ESD requirements, and firmware behavior against the manufacturer datasheet.
Recommended
Low-Voltage Sensor Acquisition
The STM32F058R8T6 is appropriate for compact sensor-acquisition and monitoring systems built around a 1.8 V MCU architecture. Its 48 MHz Cortex-M0 core can sequence sensor reads, perform local filtering, and update an interface without requiring a higher-complexity processor, while 64 KB of Flash provides space for firmware and calibration routines. The 64-LQFP package can simplify access to external sensors, status indicators, and digital interfaces. Designers must confirm the ADC characteristics, sensor input ranges, reference accuracy, and available SRAM because those details were not included in the supplied verified records.
Recommended
Motor-Control and Actuator Loops
The STM32F058R8T6 can serve as the supervisory controller in a low-voltage motor-control or actuator system because its 48 MHz Cortex-M0 core is suitable for deterministic embedded-control loops. The 64 KB Flash capacity is adequate for compact control firmware, and the 64-LQFP package provides ample pin access for pulse inputs, encoder signals, fault inputs, and gate-driver control. The verified operating range of -40 °C to +85 °C is suitable for many controlled environments. Actual motor suitability depends on timing, timer channels, analog inputs, and safety behavior that must be checked in the full manufacturer documentation.
Recommended
Communications and Protocol Hubs
The STM32F058R8T6 is suitable for small protocol-conversion or communications-control nodes that need a 32-bit Cortex-M0 processor without a high-power application processor. Its verified 48 MHz clock supports responsive handling of serial frames and supervisory logic, and 64 KB of Flash can hold the protocol stack and configuration. The 64-LQFP package provides enough pins for multiple interfaces, debug access, and status routing. Engineers must verify the exact peripheral mix, pin multiplexing, oscillator requirements, and firmware driver compatibility; similar-looking cross-brand MCUs should not be treated as drop-in replacements without complete validation.
Recommended
Compact Industrial Measurement Systems
The STM32F058R8T6 can support compact measurement systems that combine sensor conditioning, digital processing, and local communications. Its 48 MHz ARM Cortex-M0 core provides useful processing headroom for sampling control and data formatting, while 64 KB of Flash accommodates application firmware without requiring external program memory. The 64-LQFP package makes external routing and prototype rework straightforward. Before committing to a design, verify ADC resolution, sampling characteristics, SRAM, timer resources, reference voltage, and calibration support because those specifications were not available in the provided verified web data.
Recommended
Human-Machine Interface Controllers
The STM32F058R8T6 is appropriate for simple human-machine interface controllers that combine button or encoder inputs, status LEDs, display control, and local configuration. Its 48 MHz Cortex-M0 core can handle display updates and input scanning, and the 64-LQFP package provides substantially more I/O access than a compact leadless package. The 64 KB Flash capacity can hold a compact interface application. Layout work should reserve an SWD programming interface and suitable display or communications connectors. Validate pin assignments, peripheral availability, and timing against the manufacturer datasheet before using it as the principal board controller.

Key Differentiators
- Exact same-family footprint across operating grades (vs STM32F058R8T8)
- Moderate industrial temperature upgrade (vs STM32F058R8T7)
- Same electrical architecture for footprint-compatible redesigns (vs STM32F058R8T3)
Design Notes
Design the power tree around the device's verified low-voltage MCU classification and check every operating condition against the manufacturer datasheet. The supplied records identify a 1.8 V MCU architecture and also mention 2.5 V and 3.3 V conditions, but they do not provide detailed core, I/O, or regulator input limits. Confirm the exact permitted rail ranges before selecting a regulator, and include local bulk and bypass capacitors close to the supply pins to control transient impedance.
Preserve a clean implementation of the 64-LQFP footprint even when prototyping with an adapter board. Route the device's power and ground connections with low loop impedance, keep oscillator traces short, and reserve the manufacturer-defined programming interface for production programming and debug. Because an individual public pinout was not included in the supplied verified data, engineers must cross-check all 64 positions against the current STMicroelectronics package drawing before releasing artwork.
Do not treat every STM32F0 device with an LQFP package as a drop-in substitute. The STM32F058R8T6 specifically combines a 48 MHz Cortex-M0 core, 64 KB of Flash, a 64-LQFP package, and a -40 °C to +85 °C temperature grade. A replacement with different Flash capacity, pin multiplexing, peripheral availability, or temperature grade can require software and schematic changes. Validate the ordering code and complete electrical table rather than relying only on package dimensions.
For exposed industrial or automotive-adjacent installations, consider the temperature-grade selection before treating the MCU as a thermal solution. The standard STM32F058R8T6 is verified for -40 °C to +85 °C, while higher-temperature same-family ordering variants can provide more operating margin. Calculate worst-case ambient temperature, board heating, and nearby regulator dissipation, then use the manufacturer's junction-temperature limits and package thermal data to determine whether additional airflow, copper, or heat spreading is required.
Compliance Information
The supplied verified records do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals compliance. No compliance status has been assumed.
