MKL25Z128VLK4 Übersicht
A microcontroller is a compact computer integrated with nonvolatile program memory, working RAM, digital peripherals, and I/O interfaces. It executes firmware, samples sensors, controls actuators, and manages communications without requiring a separate processor. The MKL25Z128VLK4 belongs to the hierarchy Kinetis KL25 microcontroller -> Arm Cortex-M0+ MCU -> 32-bit microcontroller -> embedded processor -> semiconductor.
Its principal features include 128 KB of flash for firmware storage, 16 KB of SRAM for runtime data, a 48 MHz Cortex-M0+ core, and full-speed USB. The 80-LQFP package provides enough external connections for mixed-signal products, interface-heavy controls, and designs that favor a leaded package for inspection or assembly. The Kinetis KL2x family also supports migration paths across Kinetis KL1x, KL2x, KL3x, and KL4x devices, as stated by NXP.
The Cortex-M0+ architecture favors energy-efficient embedded execution while retaining a conventional 32-bit instruction set and integrated interrupt handling. Flash capacity allows substantially larger applications than 64 KB-class devices, while SRAM supports packet buffers, sampled data, display or communication state, and real-time control tasks. USB integration can reduce the external controller count in connected products.
Typical uses include USB data loggers, building-control endpoints, compact industrial monitors, sensor-hub boards, access-control terminals, and low-power portable instruments. The 48 MHz processing rate is suitable for concurrent USB traffic, control loops, protocol handling, and supervisory tasks where workload is modest enough not to require a higher-performance Cortex-M core.
Designers should preserve the package pin assignments, supported supply ranges, decoupling requirements, and clock configuration when creating a PCB. The 80-LQFP footprint also requires adequate solder-mask clearance and inspection because its closely spaced leads can complicate manual rework. Firmware development should account for memory-map constraints, USB clocking, peripheral pin multiplexing, and low-power state transitions.
This product page consolidates verified manufacturer and distributor identity data, sourcing links, application guidance, and compatibility analysis. Because the supplied sources do not expose complete electrical ratings, pricing values, or a verified pin list, missing fields are explicitly marked rather than inferred.

Typische Anwendungen
MKL25Z128VLK4 ist geeignet für 6 Anwendungs: USB Data Logger, Industrial Sensor Hub, Building-Control Endpoint, Portable Medical Data Module, USB Configuration Tool, Access-Control Terminal.
USB Data Logger
The MKL25Z128VLK4 fits a USB data logger because its 48 MHz Arm Cortex-M0+ core can supervise sampling and communication while 128 KB of flash stores firmware and 16 KB of SRAM holds working buffers. Full-speed USB reduces the need for a separate host controller. In this design, the MCU could timestamp sensor events, maintain a circular buffer, expose data over USB, and enter low-power states between records. The verified sources confirm the core, memory, and USB resources; exact USB mode, clocking, and supply limits must be checked in the NXP datasheet before implementation.
Empfohlen
Industrial Sensor Hub
The MKL25Z128VLK4 is appropriate for an industrial sensor hub that gathers digital measurements, performs local filtering, and reports status through a wired interface. Its 48 MHz Cortex-M0+ core supplies deterministic performance for protocol servicing, while 128 KB of flash accommodates application and update code and 16 KB of SRAM supports sample and packet buffers. The 80-LQFP package offers 80 leads for external sensing and interface routing. Verify industrial temperature limits, isolation strategy, connector protection, and EMC requirements before production use because those ratings are not included in the supplied records.
Empfohlen
Building-Control Endpoint
The MKL25Z128VLK4 can serve as a low-power building-control endpoint for translating sensors and switches into network or USB messages. Its ultra-low-power Kinetis KL25 positioning is useful for equipment that spends substantial time idle, while 48 MHz processing handles control logic, debouncing, diagnostics, and communication tasks. The 128 KB flash provides room for networking, application, and update code, and the 16 KB SRAM can support protocol state and bounded sample buffers. Validate standby current, wake time, clock source, bus voltage, and environmental ratings using the complete NXP documentation.
Empfohlen
Portable Medical Data Module
The MKL25Z128VLK4 can support portable monitoring modules when the design has modest processing requirements and prioritizes compact integration. The 48 MHz Cortex-M0+ core can run acquisition control, local filtering, user-interface state, and USB synchronization, while 128 KB flash and 16 KB SRAM provide a practical embedded resource budget. Its 80-LQFP package makes prototype inspection and rework more accessible than a fine-pitch array package. Medical use requires separate verification of electrical safety, EMC, reliability, software validation, and applicable regulatory requirements; none can be inferred from the supplied sources.
Empfohlen
USB Configuration Tool
The MKL25Z128VLK4 is well matched to a USB-connected configuration tool that receives firmware or parameters, validates them, and controls attached hardware. Its 128 KB flash provides room for a bootloader and application, 16 KB SRAM can buffer USB traffic, and the 48 MHz core can service control tasks concurrently with communication. The integrated full-speed USB capability may simplify the board architecture by avoiding a separate USB bridge. Firmware must still implement enumeration, suspend and resume behavior, watchdog policy, secure update strategy, and brownout handling as required by the product specification.
Empfohlen
Access-Control Terminal
The MKL25Z128VLK4 can coordinate credential input, status LEDs, lock or relay control, event logging, and service communications in an access-control terminal. Its 48 MHz Cortex-M0+ processor manages the control state machine, 128 KB flash stores application code, and 16 KB SRAM holds credential and event data. Full-speed USB supports commissioning or local service connectivity, while the 80-LQFP package provides ample external leads for peripherals. Production engineering must confirm USB security, credential storage requirements, fail-safe behavior, transient protection, supply tolerance, and lifecycle expectations before using it as a safety-related subsystem.

Designhinweise
Use the official NXP 80-LQFP land pattern and verify all signal assignments before routing. Keep the MCU power pins, decoupling capacitors, ground return, and exposed support connections consistent with the datasheet layout guidance. The supplied data does not specify voltage limits or named pins, so do not infer them from another KL25 package or from the related VFT4 MPN.
Define the complete power tree before USB attachment or external sensor operation. Validate the accepted supply range, USB voltage behavior, regulator tolerance, decoupling values, startup order, and brownout requirements against the authoritative NXP documentation. None of those numerical electrical limits are present in the verified search records, so a regulator cannot be selected safely from this page alone.
Place required decoupling and clock-support components according to the manufacturer reference layout, and keep high-current USB traces separate from sensitive analog or sensor paths. The 80-LQFP package offers good inspection access but still needs adequate solder-mask and copper clearances. Review USB differential routing, return paths, and connector placement with the board stack-up and the device-specific reference design.
Do not assume that two Kinetis KL25 MPNs with 128 in their names are drop-in equivalents. The package suffix determines mechanical and pin compatibility, while temperature grade, USB mode, pin multiplexing, and qualification can affect behavior. Confirm the complete ordering code, package drawing, pin table, and errata before releasing a footprint or replacing the MCU.
Compliance-Informationen
The verified NXP and distributor snippets identify the part as active but do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. No compliance claim is inferred.
