Product details
Overview
MK50DN512CLQ10 from NXP (formerly Freescale) is a 100 MHz ARM Cortex-M4 microcontroller with DSP instructions, 512 KB program flash, 128 KB SRAM, and no FlexMemory (N suffix), housed in a 144-pin LQFP package. It integrates dual 16-bit ADCs (21/22 SE + 3 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, programmable FlexTimers, and operates from 1.71–3.6 V across –40 to 85 °C - used in industrial HMI and precision sensor data acquisition systems.
For engineers reviewing the MK50DN512CLQ10 datasheet, MK50DN512CLQ10 pinout, MK50DN512CLQ10 application, or MK50DN512CLQ10 equivalent, key selection considerations include its 100 MHz Cortex-M4 core without FPU, absence of FlexNVM/FlexRAM, full-speed USB OTG with DCD, 144-pin LQFP footprint, and support for up to 25-channel single-ended ADC conversion with differential pair capability.
Technical Context
The MK50DN512CLQ10 implements an ARM Cortex-M4 core with DSP instruction set but no single-precision floating-point unit (SPFPU), delivering 1.25 DMIPS/MHz performance at 100 MHz. Its memory subsystem includes 512 KB of main program flash and 128 KB of SRAM, with no FlexNVM or FlexRAM (denoted by 'N' in part number), eliminating EEPROM emulation overhead while retaining high-speed flash execution.
Analog subsystem features dual 16-bit SAR ADCs with configurable input multiplexing (up to 25 SE + 3 DP channels total), two independent 12-bit DACs, three high-speed analog comparators with integrated 6-bit DACs, two general-purpose op-amps, and two transimpedance amplifiers - enabling simultaneous signal conditioning, conversion, and feedback control in closed-loop sensor interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK50DN512ZCMD10 | Same core, flash, SRAM, and package but in 144-pin MAPBGA (13×13 mm) instead of LQFP - different PCB layout and thermal profile. | Preferred where board space is constrained and BGA assembly is available; less accessible for prototyping or rework than LQFP. | Select when footprint density outweighs hand-soldering or debug access requirements. |
| MK51DN512ZCLQ10 | Adds segment LCD controller (32×8/36×4) and enhanced TSI capacitive touch support - same 144-pin LQFP package and memory configuration. | Better suited for embedded displays with button-less UI; unnecessary if LCD is not required, adding software complexity. | Choose only if segment LCD driving is needed; otherwise MK50DN512CLQ10 offers identical control capability at lower cost. |
Compared with MK50DN512ZCMD10 and MK51DN512ZCLQ10, the MK50DN512CLQ10 provides optimal balance of performance, analog integration, and through-hole-compatible LQFP packaging for industrial control and data acquisition - avoiding BGA assembly constraints while omitting unused LCD functionality.

FAQ
What does the 'N' in MK50DN512CLQ10 indicate?
The 'N' in MK50DN512CLQ10 denotes "program flash only" - meaning this variant has 512 KB of main program flash and 128 KB of SRAM, but no FlexNVM or FlexRAM. Unlike 'X' variants, it lacks configurable EEPROM backup or additional data flash, simplifying memory management for applications that do not require byte-erasable nonvolatile storage. MK50DN512CLQ10 thus avoids FlexMemory initialization overhead while retaining full flash execution capability.
Does MK50DN512CLQ10 support USB device charging detection?
Yes, MK50DN512CLQ10 includes integrated USB Device Charger Detect (DCD) logic compliant with USB Battery Charging Specification v1.2. This allows the MCU to autonomously identify wall adapters, charging ports, and standard downstream ports without external components. The feature is enabled via USB0_OTGCTL register configuration and is fully supported in the Kinetis SDK USB stack - essential for portable MK50DN512CLQ10-based devices requiring intelligent power management.
How many analog-to-digital converter channels does MK50DN512CLQ10 support?
MK50DN512CLQ10 supports two independent 16-bit SAR ADC modules: ADC0 with up to 21 single-ended (SE) and 3 differential pair (DP) inputs, and ADC1 with up to 22 SE and 3 DP inputs. Total usable analog input pins are 43, though some share multiplexed functions. Channel sequencing, hardware triggering, and calibration registers are fully accessible - enabling synchronized sampling across both ADCs for time-critical applications like motor current monitoring.
Is MK50DN512CLQ10 pin-compatible with other K50 family members in 144-pin LQFP?
Yes, MK50DN512CLQ10 is pin-compatible with all K50 family devices using the 144-pin LQFP package (e.g., MK50DX256ZCLQ10, MK51DN512ZCLQ10), as confirmed in Table 2 of the K50 Family Product Brief. Pin assignments for power, ground, JTAG/SWD debug, USB, and primary peripherals remain consistent across the subfamily - allowing hardware reuse and migration paths while varying flash size, FlexMemory presence, or added peripherals like segment LCD controllers.
What debug interfaces are supported by MK50DN512CLQ10?
MK50DN512CLQ10 supports IEEE 1149.1 JTAG, IEEE 1149.7 compact JTAG (cJTAG), and 2-pin Serial Wire Debug (SWD) - all accessible via the standard 10-pin ARM Cortex debug connector. Trace capabilities include TPIU, FPB, DWT, ITM, ETM, and ETB for real-time instruction and data flow analysis. These interfaces are fully supported by SEGGER J-Link, P&E Multilink, and OpenOCD toolchains - enabling full visibility into MK50DN512CLQ10 runtime behavior during development and validation.
