MK50DX256CLL10 개요
A microcontroller (MCU) integrates a processor core, memory, and peripherals onto a single chip, sitting at the center of the embedded-system hierarchy: integrated circuit -> microcontroller unit -> 32-bit MCU -> ARM Cortex-M4 MCU. The Kinetis K50 sub-family specifically targets analog-measurement-intensive systems, and the MK50DX256CLL10 is the 256 KB Flash, 100-pin variant of that family.
Key features include the 100 MHz Cortex-M4 core with DSP instructions and a hardware single-precision floating-point unit (FPU), 256 KB Flash program memory, and the K50 analog measurement engine with integrated operational amplifiers and high-speed ADC/DAC modules. Peripheral connectivity includes full-speed USB device/controller capability, multiple serial interfaces (SPI, I2C, UART), timers, and general-purpose I/O - all clocked from a flexible clock-generation system that supports low-power run modes for battery-sensitive designs.
Technically, the K50 family was originally developed by Freescale Semiconductor (now NXP), and the MK50DX256CLL10 shares silicon, documentation, and the MCUXpresso/Kinetis SDK software ecosystem with the wider K series. The 100-LQFP (14x14 mm) package with 0.5 mm pin pitch supports industrial temperature operation and standard reflow assembly. According to distributor listings, the part is currently in stock (for example 7,984 pieces at Heisener) with a unit price of approximately $13.45 as of 2026-10-18.
Typical applications include medical monitoring equipment, portable instrumentation, industrial control and sensor acquisition systems - domains where the analog measurement engine (op-amps, trans-impedance amplifiers, ADCs, DACs) reduces external component count and board area.
Design consideration: the 100 MHz core draws peak current on the 3.3 V rail, so provide solid decoupling on every VDD/VDDA pin pair and budget the analog supply separately to exploit the K50 on-chip analog performance. Flash programming is supported through JTAG/SWD and the ROM bootloader.

일반적인 애플리케이션
MK50DX256CLL10 적합 용도: 6 애플리케이션s: Medical Patient Monitoring, Portable Industrial Instrumentation, Industrial Control and Automation Nodes, USB Data Acquisition Devices, Sensor Signal Acquisition Systems, Embedded Motor Control Auxiliary Systems.
Medical Patient Monitoring
The MK50DX256CLL10 was architected specifically for medical monitoring equipment. Its K50 analog measurement engine integrates operational amplifiers and trans-impedance amplifiers ahead of high-resolution ADC modules, directly conditioning physiological signals such as ECG, respiration, and blood-pressure waveforms on-chip. In a typical design the MCU samples the front-end ADC at kilohertz rates, applies DSP-enhanced filtering using the Cortex-M4 MAC/DSP instructions, and streams data over full-speed USB to a host monitor. The 100 MHz core provides ample headroom for real-time alarm logic while the 256 KB Flash holds the acquisition and communication firmware. Integrating the analog front end reduces external component count, board area, and calibration effort versus discrete designs.

Portable Industrial Instrumentation
Handheld and benchtop instruments - multimeters, data loggers, process calibrators - benefit from the MK50DX256CLL10's combination of 100 MHz processing, 256 KB Flash for rich UI firmware, and the K50 integrated op-amps/ADCs that digitize sensor inputs without a separate analog board. The industrial temperature grade and 100-LQFP 14x14 mm package suit robust handheld housings, while low-power run and stop modes extend battery life between charges. The full-speed USB port doubles as both a programming interface and a PC-connection channel for configuration and data upload. Using the on-chip trans-impedance amplifier, current-loop or photodiode signals can be acquired directly, trimming BOM cost in volume production.
추천
Industrial Control and Automation Nodes
Factory automation nodes such as sensor hubs, small PLC I/O modules, and motor-control auxiliary controllers use the MK50DX256CLL10's multiple UART/SPI/I2C interfaces to bridge field sensors to a higher-level controller. The Cortex-M4 core executes PID and filtering routines deterministically at 100 MHz with FPU acceleration, while 256 KB Flash retains configuration tables and communication stacks. The industrial temperature grade and gull-wing 100-LQFP assembly compatibility match standard industrial PCB processes. Its USB device port provides commissioning access on the factory floor, and the K50's ADCs digitize analog status signals (pressure, level, current shunt) with no external converter, simplifying channel-count expansion across a production line.

USB Data Acquisition Devices
Full-speed USB is natively integrated in the MK50DX256CLL10, making it a compact controller for USB dongle-style DAQ devices. A typical product streams ADC samples from the K50 analog engine or external converters to a PC over USB CDC/HID, using the 100 MHz Cortex-M4 to manage double-buffered endpoints and real-time decimation filtering. The 256 KB Flash hosts USB stacks, calibration routines, and DSP post-processing. Because no external USB PHY or bridge chip is required, the entire device fits around one 100-LQFP MCU, reducing BOM and PCB size. Combining the on-chip DAC with USB control makes the same platform usable for stimulus/measure instruments and sensor emulators.

Sensor Signal Acquisition Systems
Bridge, photodiode, and low-current sensor front ends map naturally onto the MK50DX256CLL10: the K50's integrated trans-impedance amplifier converts sensor current directly at the pin, its op-amps provide gain staging, and the on-chip ADCs digitize the result with no external amplifiers. The Cortex-M4 DSP instruction set applies offset correction, linearization, and averaging at 100 MHz in real time. In weigh-scale, optical, and electrochemical sensing products this eliminates an entire analog signal-chain board section. The 100-LQFP 14x14 mm 0.5 mm-pitch package keeps the acquisition node compact, and 256 KB Flash stores per-unit calibration data in Flash-resident nonvolatile storage.
추천
Embedded Motor Control Auxiliary Systems
For small motor drives and servo accessories, the MK50DX256CLL10 contributes the FPU-accelerated Cortex-M4 core for control-loop math, ADCs for current and voltage feedback, and timer resources for PWM support, while its serial links report status to a main drive controller. The 100 MHz clock allows 10 kHz-class control loops with margin for protection and diagnostic tasks. The industrial 100-LQFP package withstands typical drive-environment temperatures. Designs needing the finest gate-drive granularity can pair the MCU with dedicated gate drivers, keeping this device focused on supervision, sequencing, and communications - roles where its analog measurement engine also tracks rail health and thermistor inputs without extra components.

설계 노트
Power the MK50DX256CLL10 from a clean 3.3 V rail. At 100 MHz the Cortex-M4 core plus USB transceiver create transient load steps; place 0.1 uF ceramic decoupling at every VDD pin pair plus bulk 10 uF per supply domain. Isolate VDDA with an RC filter (e.g., ferrite bead + 1 uF) so the K50 analog measurement engine (op-amps, ADCs) reaches datasheet accuracy - switching noise coupled into VDDA directly degrades ADC effective number of bits. Estimated: peak core current at 100 MHz is on the order of tens of mA per K-family datasheet power tables; verify with the official current-consumption tables before sizing the regulator.
The 100-LQFP 14x14 mm package has a 0.5 mm pin pitch - use 4-mil trace/space or better and solder-mask-defined pads per the NXP LQFP footprint guidelines. For analog performance, partition the board so VDDA/VRH routing and the analog engine pins stay away from USB D+/D- and fast clock nets. Provide a solid ground plane; do not split ground under the ADC. Add series resistors or common-mode chokes on the USB lines if the cable exits the enclosure, per USB 2.0 full-speed layout practice.
Verify the exact memory map before copying firmware: the MK50DX256CLL10 has 256 KB Flash, while sibling K50 parts (e.g., 512 KB variants) use different linker addresses - a binary linked for the wrong die size can silently overwrite configuration fields. Also confirm the pin-multiplexing tables: K50/K51/K53 siblings share the footprint but mux peripheral functions differently, so a drop-in swap between families requires a pin-config review, not just a footprint check. Program via SWD/JTAG; the MCU does not provide self-programming over its serial ports without a bootloader in Flash.
