Overview
MK50DX256ZCLL10 from NXP Semiconductors (formerly Freescale) is a 100 MHz ARM Cortex-M4 microcontroller with DSP extensions, 256 KB on-chip flash, 256 KB FlexNVM, 64 KB SRAM, and 4 KB FlexRAM configured as EEPROM. It features dual 16-bit ADCs (19+3 SE/DP and 18+3 SE/DP channels), two 12-bit DACs, three analog comparators, two op-amps, two transimpedance amplifiers, USB OTG LS/FS with device charger detect, six UARTs, three SPI modules, two I²C interfaces, I²S, carrier modulator transmitter, and segment LCD controller support - deployed in industrial HMI and metering systems requiring mixed-signal precision and low-power operation.
For engineers reviewing the MK50DX256ZCLL10 datasheet, MK50DX256ZCLL10 pinout, MK50DX256ZCLL10 application, or MK50DX256ZCLL10 equivalent, key selection criteria include its 100 MHz Cortex-M4 core with DSP, FlexMemory partitioning (256 KB FlexNVM + 4 KB FlexRAM), 100-pin LQFP package with 59 GPIOs (5V-tolerant), -40°C to +85°C temperature range, 1.71–3.6 V supply, and integrated USB OTG with DCD and 120 mA regulator.
Technical Context
This MCU implements a full-featured ARM Cortex-M4 core with hardware floating-point unit (FPU) not enabled in this variant (D = DSP-only), nested vectored interrupt controller (NVIC), and debug support via SWD/JTAG/cJTAG with TPIU, FPB, DWT, and ITM trace. Its memory subsystem includes independent flash banks enabling read-while-write, FlexMemory allowing dynamic allocation between program flash, data flash, and high-endurance EEPROM emulation, and 64 KB SRAM with DMA-accelerated access.
The analog subsystem integrates two synchronized 16-bit SAR ADCs with programmable gain amplifiers (PGA), voltage reference, 12-bit DACs, high-speed comparators with internal 6-bit DACs, op-amps, and transimpedance amplifiers - supporting sensor signal conditioning, closed-loop control, and precision metrology. Timing peripherals include one 8-channel FTM, two 2-channel FTM modules, CMT, PDB, PIT, and LPT for motor control, PWM generation, IR modulation, and low-power scheduling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK50DN512ZCLL10 | Same 100-pin LQFP package, but 512 KB main flash, no FlexNVM, 128 KB SRAM - lacks FlexMemory EEPROM capability | Better suited for applications needing larger bootloaders or complex protocol stacks, but cannot emulate EEPROM without software overhead | Select MK50DN512ZCLL10 only if >256 KB program flash is mandatory and external EEPROM or flash emulation is acceptable |
| MK51DX256ZCLL7 | Same pinout and peripherals, but 72 MHz max frequency, 288 KB total flash (256 KB + 32 KB FlexNVM), 64 KB SRAM, 2 KB FlexRAM | Lower performance and reduced FlexRAM size limit high-cycle data logging; suitable for cost-sensitive, lower-throughput HMI | Choose MK51DX256ZCLL7 when 100 MHz processing and 4 KB EEPROM endurance are not required - reduces power and cost |
Compared with MK50DN512ZCLL10 and MK51DX256ZCLL7, MK50DX256ZCLL10 uniquely balances 100 MHz real-time performance, 256 KB FlexNVM for robust data logging, and 4 KB FlexRAM for 10M-cycle EEPROM replacement - making it optimal for field-deployed devices requiring long-term data integrity without external components.

FAQ
What is the maximum operating frequency and core type of MK50DX256ZCLL10?
MK50DX256ZCLL10 operates at a maximum CPU frequency of 100 MHz and uses an ARM Cortex-M4 core with DSP instruction set support. It does not include a hardware floating-point unit (FPU); the 'D' in the part number denotes DSP capability only. This configuration delivers 125 DMIPS of performance while maintaining low power consumption for real-time control and signal processing tasks in the MK50DX256ZCLL10.
Does MK50DX256ZCLL10 support USB device charger detection (DCD)?
Yes, MK50DX256ZCLL10 includes full USB On-The-Go (OTG) functionality with integrated Device Charger Detect (DCD) compliant with USB Battery Charging Specification v1.2. The MK50DX256ZCLL10 uses its on-chip USB transceiver and dedicated DCD logic to automatically identify standard downstream ports (SDP), charging downstream ports (CDP), and dedicated chargers (DCP) - enabling intelligent power management in portable MK50DX256ZCLL10-based designs.
How is FlexMemory allocated in MK50DX256ZCLL10, and what is its practical use?
MK50DX256ZCLL10 contains 256 KB FlexNVM and 4 KB FlexRAM. FlexRAM is factory-configured as 4 KB high-endurance EEPROM (10M write/erase cycles), while FlexNVM can be partitioned at runtime between additional program flash, data flash, or EEPROM backup. This allows MK50DX256ZCLL10 to eliminate external EEPROM in applications like smart meters where calibration data or usage logs require frequent, reliable nonvolatile writes without wear leveling overhead.
What analog peripherals are integrated into MK50DX256ZCLL10?
MK50DX256ZCLL10 integrates dual 16-bit SAR ADCs (ADC0 with 19 SE + 3 DP channels; ADC1 with 18 SE + 3 DP channels), two 12-bit DACs, three high-speed analog comparators (each with internal 6-bit DAC), two general-purpose op-amps, two transimpedance amplifiers, and a programmable voltage reference. These peripherals enable MK50DX256ZCLL10 to perform precision sensor signal conditioning, closed-loop control, and metrology-grade measurements without external signal chain components.
Is MK50DX256ZCLL10 pin-compatible with other K50 family members in the same package?
Yes, MK50DX256ZCLL10 is pin-for-pin compatible with all other K50 family devices in the 100-pin LQFP (LL) package, including MK50DN512ZCLL10 and MK51DX256ZCLL7. This compatibility allows hardware reuse across performance tiers - for example, upgrading from 72 MHz to 100 MHz or migrating from FlexNVM-based to larger main flash variants - without PCB redesign, provided peripheral pin assignments and power delivery meet the higher-spec variant's requirements.
