STM32F410CBU6 - 100MHz Cortex-M4 MCU | STMicroelectronics
MPN: STM32F410CBU6 ✓ ActiveSTM32F410CBU6 Overview
A microcontroller is a programmable semiconductor that integrates a processor core, memory, communication interfaces, timers, and analog or digital peripherals on one package. The STM32F410 belongs to the STM32F4 family and provides a balanced combination of processing capability, integration, and power efficiency. Its UFQFPN-48 package supports space-constrained equipment while retaining a substantial set of embedded resources.
The STM32F410CBU6 operates with a 32-bit architecture at up to 100 MHz and includes 128 KB of Flash memory. Its 48-pin surface-mount package uses an exposed-pad UFQFPN construction, according to distributor and manufacturer product information. The device is intended for applications requiring embedded control rather than a general-purpose host processor, including portable medical equipment, industrial controllers, and compact consumer products.
Its Cortex-M4 architecture supports efficient embedded processing while the 128 KB Flash block provides room for firmware, configuration data, and application logic. The 48-pin UFQFPN package exposes the device's I/O and supply connections on a compact 7 mm by 7 mm footprint. Because the package includes an exposed thermal pad, PCB layout and land-pattern assembly should follow the manufacturer drawing rather than relying on a generic QFN footprint.
Typical uses include connected medical devices, industrial sensing and control modules, compact sensor nodes, and consumer accessories. The STM32F410 product family is positioned as an entry-level member of the STM32F4 series, balancing performance with integration and power efficiency. It is well suited to control tasks that benefit from an Arm Cortex-M4 core without requiring a larger package or higher-memory-density device.
During schematic capture, assign every power, ground, reset, boot, and debug connection exactly as shown in the STM32F410CB pin-description table. Place decoupling capacitors close to the relevant supply pins, follow the exposed-pad land pattern, and confirm the supported voltage and temperature limits for the selected ordering code before releasing the PCB.

Typical Applications
STM32F410CBU6 is suitable for 6 applications: Compact Medical Monitoring Equipment, Industrial Sensor and Control Module, Connected Sensor Node, Portable Consumer Accessory, Motor and Actuator Controller, Audio and Display Control Module.
Compact Medical Monitoring Equipment
The STM32F410CBU6 suits compact medical monitoring equipment that combines sensor acquisition, local control, and a human-machine interface. Its Arm Cortex-M4 core operates at up to 100 MHz, providing headroom for filtering, state-machine control, and communication tasks, while 128 KB of Flash supports a substantial embedded firmware image. The 48-pin UFQFPN package measures 7 mm by 7 mm, helping reduce board area in portable instruments. The exposed pad requires careful land-pattern implementation and adequate copper for heat spreading. For designs subject to medical quality or regulatory requirements, confirm the applicable device qualification, electrical limits, and validation process separately.
Recommended
Industrial Sensor and Control Module
The STM32F410CBU6 is appropriate for industrial sensor hubs, condition-monitoring modules, and local controllers that must evaluate measurements without relying on a host processor. The 100 MHz Cortex-M4 core can support digital filtering, protocol handling, and supervisory logic, while the integrated 128 KB Flash accommodates application firmware and calibration tables. Its compact 48-pin UFQFPN package helps reduce panel size and connector count. Designers should assign industrial I/O protection separately from the MCU pins and confirm the exact supply and temperature limits for the selected suffix before using the device in harsh factory environments.
Recommended
Connected Sensor Node
The STM32F410CBU6 can serve as the control core in a compact connected sensor node that samples inputs, applies local thresholds, and communicates status through an external radio or network interface. Its 32-bit Cortex-M4 architecture at up to 100 MHz provides useful processing headroom for protocol framing, data conditioning, and low-power state management. The 128 KB Flash block offers enough space for firmware, calibration parameters, and communication code. The small UFQFPN package supports dense board layouts, although antenna placement, exposed-pad grounding, and decoupling must be planned together to prevent switching and radio interference from degrading sensitivity.
Recommended
Portable Consumer Accessory
The STM32F410CBU6 fits portable consumer accessories that combine button or touch input, LED indication, a small display interface, and a serial peripheral. The 100 MHz Cortex-M4 core supports responsive interaction logic while the 128 KB Flash stores application code and interface tables. Its 48-pin UFQFPN footprint, measuring 7 mm by 7 mm, helps engineers minimize area in wrist-worn, desk accessory, or compact household products. Keep external display and communication interfaces on correctly assigned pins, and provide local bypass capacitance close to each supply connection to improve transient response.
Recommended
Motor and Actuator Controller
The STM32F410CBU6 can coordinate timers, feedback inputs, and actuator-control logic in compact motor-control subsystems. A 100 MHz Arm Cortex-M4 core provides faster deterministic execution than an entry-level 8-bit controller, while 128 KB of Flash is suitable for control firmware and parameter storage. The 48-pin package provides a practical mix of digital I/O for position sensing, switches, and status signaling. The exact peripheral assignments, timer channels, and pin multiplexing must be checked against the manufacturer pin table. External drivers also require suitable transients, thermal margins, and protection beyond the MCU package.
Recommended
Audio and Display Control Module
The STM32F410CBU6 can manage user-interface sequencing and audio-control functions in compact consumer electronics. Its Cortex-M4 core at up to 100 MHz handles button events, display updates, status logic, and protocol coordination, while 128 KB of Flash supports firmware for those tasks. The UFQFPN-48 package helps limit PCB area compared with larger leaded packages and supports high-density assembly. Interface performance depends on clean power, correct clock configuration, and disciplined signal routing. Keep display and communications lines away from sensitive analog paths, and use the exposed-pad footprint exactly as specified by the manufacturer.

Design Notes
Use the STM32F410CB manufacturer package drawing for the UFQFPN-48 land pattern, including the exposed-pad dimensions, mask-defined or paste-defined land recommendations, and pin-1 orientation. A generic 48-pin QFN footprint may not reproduce the exact pad and thermal-via geometry. Confirm the assembled board with the device's mechanical drawing and the PCB manufacturer's current assembly capability before releasing artwork.
Place the required bypass capacitors close to their associated supply and ground pins, with short, low-impedance connections and a solid ground reference. Keep the exposed pad tied to the appropriate ground or supply net exactly as directed by the manufacturer. Route high-speed clock and debug signals away from analog inputs and switching-node connections, and maintain symmetrical via distribution around power entry points to reduce inductance during transient events.
Verify the exact supply-voltage range, absolute maximum ratings, reset requirements, and power-up sequence in the STM32F410x8 and STM32F410xB electrical documentation before finalizing the power architecture. The target is listed as a 3.3 V device, but that operating point alone does not define startup behavior. Include adequate bulk and local decoupling, controlled supply ramp conditions where required, and a defined reset strategy for reliable firmware entry.
Do not treat a shared footprint as proof that every STM32F410 suffix is interchangeable. Verify boot configuration, pin multiplexing, oscillator requirements, debug access, flash configuration, and temperature grade for every substitute. Also confirm whether the incoming part is supplied in a tray or tape-and-reel format, because a TR suffix changes the order format even though the electrical device configuration and package remain unchanged.
Compliance Information
The listed technical and manufacturer information does not state the device-specific compliance status. Confirm RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals declarations for the selected ordering code and shipment configuration with STMicroelectronics before production release.
