NXP Semiconductors MK51DN512ZCLQ10

Overview

MK51DN512ZCLQ10 from NXP (formerly Freescale) is a 100 MHz ARM Cortex-M4 microcontroller with DSP extensions, 512 KB program flash, 128 KB SRAM, and no FlexMemory. It features 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, capacitive touch sensing (16 inputs), segment LCD controller (38×8/42×4), and IEEE 1588-capable timers - deployed in industrial HMI and metering systems.

For engineers reviewing the MK51DN512ZCLQ10 datasheet, MK51DN512ZCLQ10 pinout, MK51DN512ZCLQ10 application, or MK51DN512ZCLQ10 equivalent, key selection criteria include its 144-pin LQFP package, 100 MHz CPU frequency, absence of FlexNVM/FlexRAM, full-speed USB OTG with DCD, dual ADC/DAC capability, and support for IEEE 1588 timing in precision time-synchronized applications.

Technical Context

The MK51DN512ZCLQ10 implements an ARM Cortex-M4 core with DSP instruction set but no single-precision FPU (SPFPU). Its memory subsystem includes 512 KB main flash (no FlexNVM partitioning) and 128 KB SRAM, enabling concurrent code execution and large firmware images. The device supports up to 10 power modes, including VLPR/VLPS/LPSS, with low-leakage wake-up unit and independent-clock COP for fail-safe operation.

Analog subsystem integration includes ADC0 (21 SE + 3 DP) and ADC1 (22 SE + 3 DP), both with programmable voltage reference and hardware averaging; dual 12-bit DACs support simultaneous waveform generation; and three high-speed comparators feed into FTM/PIT for real-time control loops. USB OTG operates at full speed (12 Mbps) with integrated transceiver and dedicated 120 mA regulator plus Device Charger Detect (DCD) per USB Battery Charging Spec 1.2.

FAQ

What is the maximum operating frequency of the MK51DN512ZCLQ10?

The MK51DN512ZCLQ10 operates at a maximum CPU frequency of 100 MHz, achieved via its internal Phase-Locked Loop (PLL) and Multi-purpose Clock Generator (MCG). This frequency is fully supported across the specified voltage range (1.71 V to 3.6 V) and temperature range (−40 °C to +85 °C), enabling deterministic real-time execution for industrial control and signal processing tasks within the MK51DN512ZCLQ10.

Does the MK51DN512ZCLQ10 include FlexMemory (FlexNVM/FlexRAM)?

No, the MK51DN512ZCLQ10 does not include FlexMemory. Its part number suffix "N" indicates program flash only - 512 KB main flash and 128 KB SRAM, with no FlexNVM or FlexRAM blocks. This distinguishes it from "X"-suffix variants (e.g., MK50DX256ZCLK10) that allocate flash for EEPROM emulation or additional program/data storage, confirmed in Table 5 of the K50 Family Product Brief.

How many analog-to-digital converters does the MK51DN512ZCLQ10 support?

The MK51DN512ZCLQ10 supports two independent 16-bit SAR ADC modules: ADC0 with 21 single-ended (SE) and 3 differential pair (DP) inputs, and ADC1 with 22 SE and 3 DP inputs. Both ADCs feature programmable voltage reference, hardware averaging, and programmable conversion triggers - enabling high-accuracy, synchronized multi-channel acquisition critical in MK51DN512ZCLQ10-based metering and test equipment.

What USB capabilities does the MK51DN512ZCLQ10 provide?

The MK51DN512ZCLQ10 integrates a full-speed/low-speed USB On-The-Go controller with on-chip transceiver, dedicated 120 mA regulator, and Device Charger Detect (DCD) compliant with USB Battery Charging Specification 1.2. It supports device, host, and OTG roles, enabling field-programmable firmware updates, PC-connected data logging, and direct charging detection - all implemented without external PHY components in the MK51DN512ZCLQ10 design.

What is the package type and pin count of the MK51DN512ZCLQ10?

The MK51DN512ZCLQ10 uses a 144-pin LQFP (Low-Profile Quad Flat Package) with 20 mm × 20 mm body size and 0.5 mm pitch. This package is explicitly identified by the "LQ" code in the part number's PP field (per Figure 3 in the K50 Family Product Brief) and provides accessible routing, thermal performance suitable for industrial ambient temperatures, and compatibility with standard surface-mount assembly processes for the MK51DN512ZCLQ10.
