Product details
Overview
MK51DN256CMD10 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, operating at up to 100 MHz. It integrates 256 KB on-chip flash memory, 128 KB RAM, dual 16-bit SAR ADCs with integrated PGA (up to ×64 gain), two 12-bit DACs, and USB full-/low-speed On-The-Go controller. It targets industrial control systems requiring mixed-signal processing, real-time motor control, and low-power human-machine interface.
For engineers reviewing the MK51DN256CMD10 datasheet, MK51DN256CMD10 pinout, MK51DN256CMD10 application, or MK51DN256CMD10 equivalent, key selection considerations include its 100 MHz Cortex-M4 core with DSP, dual ADC/DAC architecture, segment LCD controller supporting up to 44 frontplanes, and support for multiple low-power stop modes down to 2.1 µA in VLLS1 mode.
Technical Context
The MK51DN256CMD10 implements a multi-clock domain architecture with independent MCG (Multipurpose Clock Generator), 3–32 MHz main crystal oscillator, and 32 kHz RTC oscillator. Its system-level timing includes eight-channel PWM/motor control timer, two quadrature decoder timers, and real-time clock with battery-backed operation.
It features a FlexBus external bus interface for parallel memory expansion, EzPort serial programming interface, and memory protection unit (MPU) supporting multi-master access arbitration. Analog subsystem integration includes transimpedance amplifiers, operational amplifiers, three analog comparators with embedded 6-bit DACs, and voltage reference module.
