Product details
Overview
MK53DX256CLQ10 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, designed for embedded control applications requiring integrated analog peripherals, secure boot, and low-power operation. It features 256 KB program flash, 256 KB FlexNVM, 4 KB FlexRAM, 128 KB RAM, operates from 1.71–3.6 V at –40 to +85°C, and delivers 125 DMIPS at 100 MHz.
For engineers reviewing the MK53DX256CLQ10 datasheet, MK53DX256CLQ10 pinout, MK53DX256CLQ10 application, or MK53DX256CLQ10 equivalent, key selection considerations include its FlexMemory architecture, hardware AES/SHA-256 encryption, dual 16-bit SAR ADCs with PGA, Ethernet MAC with IEEE 1588 support, and 144-pin LQFP package with segment LCD controller.
Technical Context
The MK53DX256CLQ10 implements a full-featured Kinetis K53 sub-family architecture centered on an ARM Cortex-M4 core with floating-point unit (FPU) disabled (D-series), paired with FlexMemory enabling configurable allocation between program flash and nonvolatile data storage. Its memory subsystem includes EzPort for serial programming and FlexBus for external memory expansion.
System-level timing relies on a multi-source clock system: primary 3–32 MHz crystal oscillator, 32 kHz RTC crystal input, and a multipurpose clock generator supporting dynamic frequency scaling. Power management integrates eight low-power modes-including VLLS1–VLLS3-with sub-μA stop-mode currents and hardware wakeup units.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| K64F120M120JMD10 | 120 MHz Cortex-M4F, 1 MB flash, 256 KB RAM, no FlexMemory, includes FPU | Better floating-point performance but lacks FlexNVM for data logging; requires external EEPROM for parameter storage | Choose when floating-point math dominates and external nonvolatile memory is acceptable |
| STM32H743VI | 480 MHz Cortex-M7, 2 MB flash, 1 MB RAM, no integrated Ethernet PHY interface, no FlexMemory | Higher compute throughput but needs external Ethernet PHY and lacks hardware LCD controller | Prefer for AI-edge inference workloads where display integration is not required |
Compared with MK53DX256CLQ10, K64F120M120JMD10 offers higher CPU speed and FPU but sacrifices FlexMemory-based data resilience, while STM32H743VI delivers superior raw performance yet increases BOM complexity with external PHY and display drivers.

FAQ
What is the maximum operating frequency of the MK53DX256CLQ10?
The MK53DX256CLQ10 operates at a maximum CPU frequency of 100 MHz, delivering 125 DMIPS and full DSP instruction support. This frequency is sustained across the full –40°C to +85°C temperature range when powered within the 1.71–3.6 V supply range. The device uses a multi-purpose clock generator with internal PLL to derive system clocks from crystal or internal oscillators.
Does the MK53DX256CLQ10 support hardware encryption?
Yes, the MK53DX256CLQ10 includes dedicated hardware acceleration for DES, 3DES, AES (128/192/256-bit), MD5, SHA-1, and SHA-256 cryptographic algorithms. It also integrates a true random number generator (TRNG) and 128-bit unique identification number per chip-enabling secure boot, encrypted firmware updates, and device authentication without software overhead.
What analog peripherals are integrated into the MK53DX256CLQ10?
The MK53DX256CLQ10 integrates two independent 16-bit SAR ADCs, each with programmable gain amplifier (up to ×64), two 12-bit DACs, two operational amplifiers, two transimpedance amplifiers, three analog comparators (each with 6-bit DAC and programmable reference), and a precision voltage reference. These peripherals support high-fidelity sensor signal conditioning and closed-loop control in industrial and medical applications.
Is the MK53DX256CLQ10 pin-compatible with other K53 family members?
No, the MK53DX256CLQ10 is not universally pin-compatible across the K53 family. While it shares the 144-pin LQFP (LQ) package with MK53DN512CLQ10, differences in FlexMemory configuration, peripheral enablement, and signal multiplexing mean that direct substitution requires validation of pin function mapping, power sequencing, and software initialization. Always consult the specific device's pin assignment table before replacement.
What development tools support the MK53DX256CLQ10?
The MK53DX256CLQ10 is supported by NXP's MCUXpresso SDK and IDE, Kinetis Design Studio (legacy), and third-party tools including IAR Embedded Workbench and Keil MDK. Hardware evaluation is enabled via the FRDM-K53N512 board (which uses the pin-compatible MK53DN512CLQ10) and custom carrier boards leveraging the 144-pin LQFP footprint. Debugging uses SWD/JTAG via CMSIS-DAP or OpenSDA interfaces.
