Overview
MK50DX256CLL10 from NXP (formerly Freescale) is a 100 MHz ARM Cortex-M4 microcontroller with DSP instructions, 256 KB flash, 64 KB SRAM, and 256 KB FlexNVM for configurable EEPROM/data flash backup, designed for low-power industrial HMI and USB OTG-enabled embedded control systems.
For engineers reviewing the MK50DX256CLL10 datasheet, MK50DX256CLL10 pinout, MK50DX256CLL10 application, or MK50DX256CLL10 equivalent, this page delivers verified technical context, package mapping, functional alternatives, and real-world use-value for segment LCD controllers, USB device charger detection, and mixed-signal timing-critical designs.
Technical Context
The MK50DX256CLL10 implements an ARM Cortex-M4 core with hardware-accelerated DSP instructions and a nested vectored interrupt controller (NVIC), supporting deterministic real-time response in safety-aware applications. It integrates dual 16-bit SAR ADCs (19+18 SE/DP channels), two 12-bit DACs, three analog comparators, and two op-amps for on-chip signal conditioning.
Its clock system includes MCG with FLL/PLL, 32 kHz RTC oscillator, and low-power timer - enabling operation across 10 power modes. The FlexMemory subsystem provides 256 KB FlexNVM partitionable as program flash extension or high-endurance EEPROM backup (up to 10M cycles), plus 4 KB FlexRAM for byte-write EEPROM emulation without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK51DX256CLL10 | Same 100 MHz Cortex-M4 core, identical pinout and memory map, but adds segment LCD controller (32×8/36×4) and TSI capacitive touch support. | Required for designs needing built-in LCD driving or touch-button interfaces; not needed if those peripherals are implemented externally. | Select MK51DX256CLL10 only when segment LCD or capacitive touch functionality is required - otherwise MK50DX256CLL10 offers lower cost and same core performance. |
| MKE15Z256VLH7 | ARM Cortex-M0+ core, 72 MHz, 256 KB flash, no FlexNVM, no USB OTG - lacks DCD, FlexMemory, and DSP acceleration. | Suitable for cost-sensitive, non-USB, low-compute applications; cannot replace MK50DX256CLL10 in USB-charging or high-precision analog roles. | Choose MKE15Z256VLH7 only for simple control tasks without USB connectivity or high-endurance EEPROM needs - it is not a functional substitute for MK50DX256CLL10 in mixed-signal USB applications. |
Compared with MK51DX256CLL10, MK50DX256CLL10 omits segment LCD and TSI but retains identical analog/USB/performance specs - making it optimal for non-LCD industrial control. Versus MKE15Z256VLH7, MK50DX256CLL10 delivers 1.4× higher DMIPS/MHz, USB OTG with DCD, and FlexNVM - essential for field-upgradable, battery-charging embedded systems.

FAQ
What is the maximum operating frequency of the MK50DX256CLL10?
The MK50DX256CLL10 operates at a maximum CPU frequency of 100 MHz, enabled by its ARM Cortex-M4 core with DSP extensions and optimized memory subsystem. This frequency is achievable across the full industrial temperature range (–40 °C to +85 °C) when supplied within the 1.71 V to 3.6 V operating voltage window. The MK50DX256CLL10 achieves 125 DMIPS at this speed, supporting real-time control loops and signal processing without external accelerators.
Does the MK50DX256CLL10 support USB Device Charger Detect (DCD)?
Yes, the MK50DX256CLL10 includes dedicated hardware for USB Device Charger Detect compliant with USB Battery Charging Specification 1.2. This allows the MK50DX256CLL10 to identify SDP, CDP, and DCP charging ports and negotiate up to 1.5 A current draw without host enumeration. The DCD function is integrated into the USB OTG controller and requires no additional external components - a key differentiator versus basic USB-only MCUs.
How is FlexMemory configured on the MK50DX256CLL10?
The MK50DX256CLL10 features 256 KB of FlexNVM and 4 KB of FlexRAM. FlexNVM can be partitioned as additional program flash, data flash, or EEPROM backup space; FlexRAM serves as high-endurance EEPROM emulation memory. Configuration is performed via flash configuration field settings at boot - enabling runtime-selectable trade-offs between EEPROM size (up to 4 KB), endurance (10M cycles), and flash capacity without hardware changes.
What analog peripherals are integrated into the MK50DX256CLL10?
The MK50DX256CLL10 integrates two 16-bit SAR ADCs (ADC0 with 19 SE + 3 DP channels; ADC1 with 18 SE + 3 DP channels), two 12-bit DACs, three analog comparators, two general-purpose op-amps, two transimpedance amplifiers, and a programmable voltage reference. These peripherals support simultaneous sampling, hardware-triggered conversions, and flexible routing - enabling precision sensor interfacing, closed-loop control, and analog front-end consolidation in a single chip.
Is the MK50DX256CLL10 pin-compatible with other Kinetis K50 devices?
Yes, the MK50DX256CLL10 uses the 100-pin LQFP package (LL suffix), and all K50 devices sharing the LL package identifier - including MK50DX256CLK10, MK50DN512ZCLL10, and MK51DX256CLL10 - are pin-for-pin compatible. This allows hardware reuse across performance tiers (72 MHz vs. 100 MHz) and memory variants (FlexNVM vs. no FlexNVM), provided software accounts for peripheral differences such as segment LCD or TSI presence.
