NXP Semiconductors MK51DN512CLL10

Overview

MK51DN512CLL10 from NXP Semiconductors (formerly Freescale) is a 100 MHz ARM Cortex-M4 core MCU with DSP extensions, 512 KB on-chip program flash, 128 KB RAM, and integrated analog peripherals including dual 16-bit SAR ADCs with PGA, dual 12-bit DACs, op-amps, and comparators - deployed in industrial control and sensor interface applications.

For engineers reviewing the MK51DN512CLL10 datasheet, MK51DN512CLL10 pinout, MK51DN512CLL10 application, or MK51DN512CLL10 equivalent, key selection considerations include its 100 MHz operation under 1.71–3.6 V supply, -40 to +85°C temperature range, LQFP-100 package, USB OTG support, and FlexMemory absence (N = flash-only configuration).

Technical Context

This MCU implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC, paired with a multi-purpose clock generator supporting 3–32 MHz crystal and 32 kHz RTC oscillator inputs. Its memory subsystem includes 512 KB of program flash (no FlexNVM/FlexRAM), 128 KB SRAM, and EzPort serial programming interface.

The peripheral set integrates eight-channel PWM/motor control timer, two quadrature decoder timers, real-time clock, USB full-/low-speed OTG with on-chip transceiver, SDHC, I²S, five UARTs, three SPIs, two I²Cs, and a segment LCD controller supporting up to 40×8 or 44×4 segments - all operating within a unified low-power architecture featuring six power modes and MPU-based memory protection.

FAQ

What is the maximum operating frequency of the MK51DN512CLL10?

The MK51DN512CLL10 operates at a maximum core frequency of 100 MHz, achieved using the internal multi-purpose clock generator with external crystal or internal reference. This frequency is fully supported across the entire -40 to +85°C ambient temperature range and 1.71–3.6 V supply voltage, enabling deterministic real-time performance for motor control and sensor processing tasks without thermal throttling.

Does the MK51DN512CLL10 include FlexMemory?

No, the MK51DN512CLL10 does not include FlexMemory. The 'N' in the part number suffix indicates "Program flash only" configuration, meaning it contains 512 KB of program flash memory and 128 KB of RAM, but no FlexNVM or FlexRAM. Devices with FlexMemory use the 'X' suffix (e.g., MK51DX256CLL10). This distinction affects EEPROM emulation capability and data retention architecture.

What package type is used for the MK51DN512CLL10?

The MK51DN512CLL10 uses a 100-pin LQFP package (14 mm × 14 mm), identified by the 'LL' in the part number. It is lead-free, RoHS-compliant, and rated at moisture sensitivity level 3 per J-STD-020 - requiring bake conditioning before reflow if exposed beyond floor life. Pin assignments follow the K51 signal multiplexing scheme documented in Section 8 of the K51 Sub-Family Data Sheet.

Which communication interfaces are supported by the MK51DN512CLL10?

The MK51DN512CLL10 supports USB full-/low-speed On-The-Go with integrated transceiver, three SPI modules, two I²C modules, five UART modules, SDHC, and I²S. It does not include Ethernet MAC or CAN controllers. All interfaces are accessible via multiplexed GPIO pins, with dedicated hardware blocks ensuring concurrent operation - for example, USB and SDHC can operate simultaneously while UARTs handle sensor telemetry.

How does the MK51DN512CLL10 manage power in battery-operated applications?

The MK51DN512CLL10 supports six low-power modes, including VLLS1–VLLS3 with currents as low as 2.1 μA at -40 to +25°C. In VLLS3 mode, the RTC remains active with 32 kHz oscillator running from VBAT, enabling wake-up on alarm or external interrupt while preserving RAM contents. This architecture allows multi-year operation on coin-cell batteries in wireless sensor nodes and portable medical devices.
