C8051F574-IM - 50MHz 8-Bit Flash MCU | Silicon Labs
Référence : C8051F574-IM ✗ Fin de vieC8051F574-IM Présentation
A microcontroller is a programmable semiconductor device that integrates a processor core, memory, and peripherals into one package. In the broader hierarchy, the C8051F574-IM is an MCU, an embedded controller, and a flash-memory microcontroller. The 8051 architecture provides a familiar instruction set and development environment, while the higher operating frequency supports faster control-loop execution and responsive peripheral handling.
The C8051F574-IM is identified as an 8-bit device with 50 MHz performance and 16 KB, or 16K x 8, of flash memory. Its 40-QFN package supports surface-mount assembly and provides a compact solution for embedded products requiring mixed-signal control, data acquisition, communication, or general-purpose automation. The family designation C8051F57x indicates a device within Silicon Labs' C8051 mixed-signal flash MCU product line.
The available product information confirms the core device identity, flash capacity, clock frequency, architecture, and package dimensions. Detailed peripheral inventories, electrical limits, pin names, and memory-map functions should be confirmed against the manufacturer datasheet before a new PCB is released. The package drawing and pin-assignment table are especially important because the 40-QFN footprint includes a fine-pitch lead arrangement and an exposed thermal pad.
Typical applications for this MCU include industrial control modules, compact sensor interfaces, motor-control subsystems, communication equipment, and low-cost embedded instruments. The mixed-signal capability is useful when a system must combine digital control with analog measurement or control functions while keeping the component count and board area low. The 50 MHz clock can improve timing margin for protocol handling and real-time control tasks, subject to the peripheral and electrical limits in the datasheet.
When designing around the C8051F574-IM, begin with the datasheet pin description, memory organization, clock requirements, decoupling recommendations, and programming interface. Verify the exposed-pad connection and thermal design before production, because the 40-QFN package is intended for compact surface-mount layouts rather than through-hole assembly. This page combines the confirmed C8051F574-IM specifications with packaging guidance, application context, and the available verified cross-reference information for engineering planning.

Applications typiques
C8051F574-IM convient pour 6 applications: Industrial Control Module, Sensor Interface and Data Acquisition, Motor and Actuator Control, Communication Gateway, Battery-Powered Embedded Instrument, Automated Test Equipment.
Industrial Control Module
The C8051F574-IM fits compact industrial control modules that require deterministic embedded processing in a small board area. Its 8-bit 8051 architecture and 50 MHz operating frequency provide a practical platform for sequencing, interlocks, status logic, and peripheral servicing, while 16 KB of flash stores application firmware directly on the controller. The 40-QFN, 6 x 6 mm package supports dense assemblies when analog and digital functions must share one controller. Confirm the operating-temperature grade and available peripheral set against the manufacturer datasheet before assigning it to a production machine-control board.
Recommandé
Sensor Interface and Data Acquisition
The C8051F574-IM can serve as the central controller in a compact sensor-interface assembly when an 8-bit mixed-signal MCU, 50 MHz execution rate, and local program storage are sufficient. The 16 KB flash capacity allows firmware, calibration logic, and communication routines to reside on the same device, helping reduce board complexity. Its QFN package also permits placement close to analog and digital circuitry. Verify the exact ADC resolution, analog input count, reference arrangement, and acquisition timing in the datasheet before selecting it for precision measurement designs.
Recommandé
Motor and Actuator Control
The C8051F574-IM is appropriate for small motor-control or actuator-management subsystems where a compact 8-bit controller can execute control software and coordinate discrete outputs. Its 50 MHz operating frequency supports responsive task scheduling and peripheral servicing, while the 16 KB flash stores control code without requiring an external program-memory device. The 40-QFN package helps minimize controller footprint in space-constrained assemblies. Before design release, confirm timer resources, PWM outputs, analog feedback channels, supply limits, and thermal conditions because these details are not specified in the product listing.
Recommandé
Communication Gateway
The C8051F574-IM can support compact communication adapters or gateway peripherals that translate between a local sensor network and a higher-level controller. The 50 MHz clock provides processing headroom for protocol handling and buffering, and the 16 KB flash permits firmware, protocol tables, and configuration logic to be integrated into one device. Its small 40-QFN footprint is useful in gateways where connector and component placement constrain board area. The available serial-interface configuration must be checked in the datasheet to confirm that the required UART, SPI, or other communication resources are present.
Recommandé
Battery-Powered Embedded Instrument
The C8051F574-IM is suitable for compact embedded instruments in which local control, compact packaging, and integrated flash storage are priorities. The 8-bit C8051 core can manage measurement sequencing, display updates, user inputs, and communication in a single controller, while the 40-QFN package preserves board area for sensors or power circuitry. The product listing identifies a 5 V operating-voltage entry, but the complete electrical operating range must be verified before battery-system design. Low-power modes, oscillator options, and wake-up behavior also require confirmation in the manufacturer documentation.
Recommandé
Automated Test Equipment
The C8051F574-IM can be used as the embedded controller in compact automated test equipment when sequence control, fixture communication, and status reporting fit within an 8-bit architecture. Its 50 MHz operating frequency allows the firmware to coordinate measurements and interface handling efficiently, and 16 KB of flash provides room for the control application and communication routines. The 40-QFN package supports compact instrument designs. Instrument designers should confirm the required analog functions, interface count, timing performance, and operating-temperature range in the datasheet before finalizing the controller architecture.

Notes de conception
Base the 40-QFN land pattern on the manufacturer package drawing rather than only the 6 x 6 mm body dimension. Confirm terminal length, width, pitch, exposed-pad size, and solder-mask opening before fabrication. Place decoupling capacitors close to the device power terminals and route ground returns through the exposed-pad connection specified by the manufacturer.
Keep clock, programming, and high-speed communication traces away from analog inputs and sensitive sensor connections. If the C8051F57x device includes mixed-signal functions, use a clear partition between digital return paths and analog reference or measurement circuitry. Follow the datasheet's recommended grounding and reference-layout guidance for the exact peripheral configuration.
Do not treat the -IM and -IMR suffixes as equivalent without checking the manufacturer ordering table. The product snippets match on architecture, frequency, flash size, and package, but temperature grade, packing, and other suffix-specific attributes remain to be confirmed. Review the complete datasheet and ordering information before approving either part for production.
Informations de conformité
No specific RoHS, REACH, lead-free, halogen-free, or conflict-minerals status was identified for C8051F574-IM. AEC-Q100 qualification is not applicable to the listed standard-grade ordering code, but an automotive grade would require a separately identified qualified part.
