NXP Semiconductors MK53DN512CLQ10

Overview

MK53DN512CLQ10 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, operating at up to 100 MHz, featuring 512 KB on-chip flash memory, 128 KB RAM, and integrated analog peripherals including dual 16-bit SAR ADCs, two 12-bit DACs, and hardware encryption engines. It targets industrial control and connected HMI applications requiring real-time processing, low-power operation, and secure firmware execution.

For engineers reviewing the MK53DN512CLQ10 datasheet, MK53DN512CLQ10 pinout, MK53DN512CLQ10 application, or MK53DN512CLQ10 equivalent, key selection considerations include its 100 LQFP (14 mm × 14 mm) package, -40°C to +85°C temperature grade, FlexBus interface for external memory expansion, IEEE 1588-capable Ethernet controller, and support for multiple low-power stop modes with sub-10 μA VLLS3 current.

Technical Context

The MK53DN512CLQ10 implements an ARM Cortex-M4 core with single-cycle DSP instructions and a Memory Protection Unit (MPU), enabling deterministic real-time execution in safety-aware systems. Its clock system integrates a multi-purpose clock generator with 3–32 MHz and 32 kHz crystal oscillators, plus internal trimming for precise low-power RTC operation.

Peripherals are organized around a high-bandwidth crossbar switch: the FlexBus supports external SRAM/Flash/NOR, the EzPort enables serial programming, and the Ethernet MAC includes MII/RMII interfaces with hardware timestamping for time-sensitive networking. Analog subsystems feature PGA-integrated ADCs, transimpedance amplifiers, and programmable comparators with embedded 6-bit DACs - all sharing common voltage references and supply domains.

FAQ

What is the maximum operating frequency of the MK53DN512CLQ10?

The MK53DN512CLQ10 operates at a maximum CPU frequency of 100 MHz, achieved using its internal multi-purpose clock generator with external crystal support up to 32 MHz and PLL multiplication. This frequency is fully supported across the full -40°C to +85°C temperature range and 1.71–3.6 V supply voltage, delivering 1.25 Dhrystone MIPS per MHz as verified in the K53 Sub-Family Data Sheet Rev. 3.

Does the MK53DN512CLQ10 include a hardware floating-point unit (FPU)?

No, the MK53DN512CLQ10 does not include a hardware FPU. Its part number suffix "D" indicates Cortex-M4 with DSP extensions only; FPU support is reserved for "F"-suffix variants like MK53FN512. The MK53DN512CLQ10 relies on integer arithmetic and optimized DSP libraries for fixed-point signal processing, which is sufficient for most industrial control and sensor fusion workloads.

What package type and pin count does the MK53DN512CLQ10 use?

The MK53DN512CLQ10 uses a 100-pin LQFP package (14 mm × 14 mm), identified by the "LQ" field in its part number. This package provides full access to all peripherals including Ethernet MII signals, FlexBus address/data lines, multiple UART/SPI/I2C interfaces, and analog inputs - and is footprint-compatible with other K53 family members in the same LQ package variant.

Can the MK53DN512CLQ10 execute code directly from external memory?

Yes, the MK53DN512CLQ10 supports XIP (eXecute-In-Place) from external memory via its FlexBus interface. When configured for synchronous mode with appropriate wait states, the processor can fetch and execute instructions directly from external NOR Flash or SRAM mapped into the memory map - extending effective code space beyond the on-chip 512 KB flash while maintaining deterministic timing.

What low-power modes are supported by the MK53DN512CLQ10, and what is the lowest achievable current?

The MK53DN512CLQ10 supports seven low-power modes, including VLLS1/VLLS2/VLLS3 stop modes. In VLLS3 mode with RTC and LLWU enabled, typical current consumption is 3.0 μA at 3.0 V and 25°C - verified in Table 6 of the K53 Sub-Family Data Sheet. This mode retains RAM and selected registers while disabling clocks to all major subsystems except the 32 kHz oscillator and low-leakage wakeup logic.
