NXP Semiconductors MK51DN512CMD10

Overview

MK51DN512CMD10 from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, designed for embedded control applications requiring integrated analog precision, low-power operation, and USB connectivity. It delivers 100 MHz CPU performance, 512 KB on-chip flash, 128 KB RAM, dual 16-bit SAR ADCs with PGA, two 12-bit DACs, and operates across –40 to +85°C at 1.71–3.6 V supply.

For engineers reviewing the MK51DN512CMD10 datasheet, MK51DN512CMD10 pinout, MK51DN512CMD10 application, or MK51DN512CMD10 equivalent, key selection considerations include its LQFP-144 package, USB On-The-Go support, segment LCD controller, TSI touch interface, and multi-mode power management for battery-powered industrial and medical devices.

Technical Context

The MK51DN512CMD10 implements an ARM Cortex-M4 core with hardware DSP instructions and a Memory Protection Unit (MPU), supporting deterministic real-time execution in safety-aware systems. Its clock system integrates a 3–32 MHz main crystal oscillator, 32 kHz RTC oscillator, and Multi-Purpose Clock Generator (MCG) with multiple internal/external source options.

Analog subsystem integration includes two independent 16-bit SAR ADCs each with programmable gain amplifier (up to ×64), two 12-bit DACs, three analog comparators with integrated 6-bit DACs, and dedicated transimpedance amplifiers - all sharing a common voltage reference and operating from the same 1.71–3.6 V analog supply (VDDA).

FAQ

What is the maximum operating frequency of the MK51DN512CMD10?

The MK51DN512CMD10 operates at a maximum CPU frequency of 100 MHz, enabled by its ARM Cortex-M4 core with DSP extensions. This frequency is supported across the full –40°C to +85°C temperature range and 1.71–3.6 V supply voltage, with timing validated under FEI/FEE clock modes and appropriate flash wait states. The MK51DN512CMD10 achieves 1.25 Dhrystone MIPS per MHz, delivering 125 DMIPS performance.

Does the MK51DN512CMD10 support USB device and host functionality?

Yes, the MK51DN512CMD10 integrates a full-/low-speed USB On-The-Go (OTG) controller with an on-chip transceiver, enabling both device and host roles without external PHY components. It supports standard USB classes including CDC, HID, and MSC, and includes dedicated USB_DP/USB_DM pins compliant with USB 2.0 specifications. The MK51DN512CMD10 also provides VREGIN input for USB regulator operation.

What analog peripherals are integrated into the MK51DN512CMD10?

The MK51DN512CMD10 integrates dual 16-bit SAR ADCs with programmable gain amplifiers (up to ×64), two 12-bit DACs, three analog comparators (each with a 6-bit DAC and programmable reference), two operational amplifiers, two transimpedance amplifiers, and a precision voltage reference. All analog modules share the VDDA supply and are specified over the full operating temperature and voltage range. These resources are accessible via dedicated pins documented in the MK51DN512CMD10 pinout.

Which low-power modes does the MK51DN512CMD10 support, and what are their typical current draws?

The MK51DN512CMD10 supports seven low-power modes, including VLPR, VLPW, STOP, VLPS, LLS, and VLLS1–VLLS3. At 3.0 V and –40°C to 25°C, VLLS3 draws as low as 3.0 μA while retaining RTC, RAM, and selected wake-up sources; VLPS draws 83 μA; and LLS draws 4.58 μA. These values are measured with all clocks disabled except those required for retention, and are confirmed in the MK51DN512CMD10 datasheet Section 5.2.5.

Is the MK51DN512CMD10 pin-compatible with other Kinetis K51 devices?

No, the MK51DN512CMD10 is not universally pin-compatible across all Kinetis K51 variants. While it shares the 144-pin LQFP (LQ) package identifier with MK51DN512CLQ10, differences in peripheral mapping, signal multiplexing, and power domain assignments mean PCB layout must be verified against the specific MK51DN512CMD10 pinout table. Pin compatibility is only guaranteed within identical package variants and revision levels - always consult the MK51DN512CMD10-specific signal assignment documentation before reuse.
