MK50DX256CLK10 Overview
A microcontroller is a semiconductor device that integrates a processor core, nonvolatile program memory, volatile working memory, and peripherals such as timers, communications interfaces, and analog blocks. The ARM Cortex-M4 core belongs to the microcontroller hierarchy rather than the FPGA, DSP, or discrete logic categories. In the Kinetis K50 family, the combination of a 100 MHz core and 256 KB Flash supports more capable control firmware than a basic low-end MCU while retaining a compact embedded footprint.
The verified product data specifically identifies a 32-bit ARM Cortex-M4 processor, 100 MHz operating speed, 256 KB Flash organized as 256K x 8, and an 80-FQFP package. The package is also described as an 80-LQFP package in distributor and comparison listings. Because the available verified data does not provide a complete pin table, SRAM value, GPIO count, ADC resolution, or operating-temperature range, those parameters are marked for data completion rather than inferred.
The MK50DX256CLK10 is positioned for embedded control, data acquisition, communications, industrial control, and connected equipment. Its 256 KB Flash capacity can hold application firmware and configuration data, while the 100 MHz Cortex-M4 core provides processing headroom for interrupt-driven control and protocol handling. The 12 x 12 mm LQFP package is intended for through-hole PCB assembly rather than the smallest surface-only designs.
When integrating this MCU, verify the complete pin assignment and peripheral multiplexing before routing the PCB. Provide the required power, decoupling, clock, reset, and programming connections according to the manufacturer datasheet. Firmware and hardware decisions should also account for the exact peripheral variants and electrical limits, since the supplied search results do not provide a complete manufacturer datasheet parameter table.
This page combines verified manufacturer and distributor product information, package and processor parameters, purchasing context, and engineering guidance. The listed alternative status is intentionally conservative: the supplied cross-reference search identified comparison references but did not establish any verified pin-to-pin drop-in replacement with complete parameter confirmation.

Typical Applications
MK50DX256CLK10 is suitable for 6 applications: Industrial embedded control, Data acquisition and instrumentation, Connected industrial equipment, Motor and actuator control, Medical monitoring controller, Human-interface and embedded control board.
Industrial embedded control
The MK50DX256CLK10 fits industrial embedded-control prototypes that need a 100 MHz ARM Cortex-M4 core and 256 KB of local Flash. Its 32-bit processing headroom is useful for state machines, supervisory logic, timing, and communication tasks running alongside a simple control panel. The 80-pin 12 x 12 mm LQFP package also provides through-hole assembly and a generous connection count for power, reset, clock, and peripheral routing. Before deployment, verify the temperature range, EMC behavior, watchdog implementation, and exact peripheral assignments in the manufacturer documentation.
Recommended
Data acquisition and instrumentation
The 100 MHz Cortex-M4 core can coordinate sampling, filtering, calibration, and host communication in an instrumentation design. The 256 KB Flash capacity is suitable for embedded firmware and fixed parameters, while the 80-pin package can expose multiple sensor, interface, and control signals. The verified results do not confirm the MK50DX256CLK10-specific ADC, DAC, channel count, resolution, or analog input range, so analog front-end design must begin with the complete NXP datasheet rather than assumptions from the Kinetis family name.
Recommended
Connected industrial equipment
MK50DX256CLK10 can serve as the central controller in connected industrial equipment that requires deterministic control plus a substantial firmware image. A 100 MHz ARM Cortex-M4 provides headroom for protocol state machines, diagnostics, and real-time interrupts, while 256 KB Flash supports application code and configuration. The exact UART, USB, CAN, Ethernet, or other communications options are not confirmed by the supplied verified data, so the selected board should verify peripheral availability and pin multiplexing before external-interface implementation.
Recommended
Motor and actuator control
The 32-bit Cortex-M4 core is suitable for coordinating motor-control sequencing, position logic, fault handling, and communication in actuator systems. The 100 MHz clock provides computational margin for control algorithms, while the 80-pin package can support digital control signals, external interfaces, and protection monitoring. The supplied data does not verify motor-control peripherals, PWM channels, timers, operating temperature, or safety qualification; therefore, this application requires checking the exact device datasheet and using external drivers where appropriate.
Recommended
Medical monitoring controller
The MK50DX256CLK10 may be evaluated as a supervisory controller in medical monitoring equipment because it combines a 100 MHz 32-bit core with 256 KB Flash. That processing capacity can support sensor management, timing, event logging, and communications while the embedded package supports through-hole assembly. However, the verified data does not establish medical-device certification, AEC-Q100 status, temperature limits, ADC accuracy, or safety diagnostics. Medical use requires a formal risk assessment, component qualification review, and validation against the applicable regulatory requirements.
Recommended
Human-interface and embedded control board
The 80-pin LQFP package and 100 MHz core make the MK50DX256CLK10 suitable for a board combining local control, display or keypad handling, status LEDs, and external serial communications. The 256 KB Flash capacity can hold a production-oriented control application without an external program-memory device. The supplied search snippets mention Kinetis-family analog resources, but they do not verify the exact display, USB, UART, or GPIO functions of this MPN. Schematic design must therefore use the official pin-multiplexing table for the selected package.

Key Differentiators
- Verified 100 MHz Cortex-M4 processing class (vs MK51DX256CLK10)
- Explicit 256 KB Flash configuration (vs MK22DX256VLF5)
- Known package format for through-hole PCB assembly (vs MK20DN512ZVMC10R-FR)
- Supplier sourcing visibility (vs MK53DX256ZCLQ10)
Design Notes
Begin layout from the exact NXP pin table and 80-pin package drawing, not from the distributor package description. Route the required power, ground, reset, clock, and programming pins first, then place decoupling capacitors close to their specified pins. The verified data confirms the 12 x 12 mm LQFP format but does not provide pin names or exposed-pad details, so do not finalize copper until those details are confirmed.
Do not assume that another 256 KB NXP MCU is electrically and pin-compatible. A shared LQFP outline, memory size, or Cortex-M-family association does not guarantee identical power pins, alternate functions, peripheral routing, or memory map. Check the official pin table, maximum frequency, voltage range, startup behavior, and programming interface for each candidate before approving a replacement.
Treat clock, programming, reset, and communication signals as potentially sensitive despite the relatively compact 100 MHz MCU. Keep clock routing short and away from noisy switching nodes, provide clean return paths for high-speed signals, and reserve test points for firmware debugging and manufacturing. Exact trace geometry should follow the NXP application guidance and the board's stackup and external components.
Validate the complete power tree before schematic release. The verified listing identifies 3.3 V operation, but it does not provide core current, IO current, brownout behavior, regulator sequencing, or absolute maximum limits. Use the manufacturer electrical specifications to select the regulator, decoupling, load-switch, and protection components, then verify startup and shutdown behavior in the final board design.
The LQFP package is suitable for conventional PCB assembly, but thermal performance depends on the board copper, airflow, and power dissipation. The verified data does not provide power dissipation or junction-temperature values, so no thermal estimate can be responsibly calculated here. Use the manufacturer thermal data and worst-case operating current in the final thermal review.
Compliance Information
The supplied verified data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance claims must be confirmed from current NXP documentation.
