NXP Semiconductors MK11DN512VLK5

Overview

MK11DN512VLK5 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 core microcontroller with DSP extensions, designed for embedded control in industrial and automotive applications requiring high reliability, cryptographic security, and low-power operation. It operates at up to 50 MHz, features 512 KB of program flash memory, 64 KB RAM, and supports -40°C to +105°C ambient temperature.

For engineers reviewing the MK11DN512VLK5 datasheet, MK11DN512VLK5 pinout, MK11DN512VLK5 application, or MK11DN512VLK5 equivalent, key selection criteria include its FlexMemory-free flash architecture, hardware AES/SHA-256 acceleration, 16-bit SAR ADC, quad UART interface, and 80-pin LQFP package with full peripheral multiplexing support.

Technical Context

The MK11DN512VLK5 implements an ARM Cortex-M4 core with single-cycle DSP instructions and no FPU, delivering 1.25 Dhrystone MIPS per MHz. Its clock system integrates a 3–32 MHz crystal oscillator, 32 kHz RTC oscillator, and multi-purpose clock generator supporting dynamic frequency scaling across RUN, VLPR, VLPS, and VLLS power modes.

Security is enforced via dedicated hardware modules: CRC engine, tamper detection, true random number generator, and cryptographic accelerators for DES, 3DES, AES, MD5, SHA-1, and SHA-256. Memory subsystem includes 512 KB on-chip flash (no FlexNVM), 64 KB SRAM, and EzPort serial programming interface.

FAQ

What is the maximum operating frequency of the MK11DN512VLK5?

The MK11DN512VLK5 operates at a maximum system and core clock frequency of 50 MHz. This is achieved using the internal MCG clock generator in FEI or PEE mode with a 3–32 MHz crystal source. The 50 MHz limit applies across the full -40°C to +105°C temperature range and 1.71–3.6 V supply voltage, as validated in the K11 Sub-Family Data Sheet Rev. 4.1.

Does the MK11DN512VLK5 include FlexMemory (FlexNVM/FlexRAM)?

No, the MK11DN512VLK5 does not include FlexMemory. Its part number encoding confirms this: the 'N' in position 5 indicates "program flash only", and documentation explicitly states "up to 512 KB of program flash for devices without FlexNVM". Devices with FlexNVM use 'X' in that position (e.g., MK11DX256VLK5). The MK11DN512VLK5 provides 512 KB flash and 64 KB SRAM only.

What communication interfaces are supported by the MK11DN512VLK5?

The MK11DN512VLK5 supports four UART modules, two SPI modules, two I²C modules, one I²S module, and USB Device Charger Detect. It does not include CAN or Ethernet controllers. All UARTs support LIN break detection and smart card protocols; SPI modules support DSPI mode with programmable frame size and FIFO buffering - enabling robust industrial fieldbus and sensor interface designs.

How does the MK11DN512VLK5 handle low-power operation in battery-backed applications?

The MK11DN512VLK5 supports six low-power modes, including VLLS0 with typical current as low as 0.359 µA (POR disabled, –40°C to 25°C). Its RTC operates independently on VBAT with 32 kHz crystal support, and the low-leakage wakeup unit detects external events without waking the core. These capabilities make the MK11DN512VLK5 suitable for decade-long deployments in metering and remote sensing where battery replacement is impractical.

Is the MK11DN512VLK5 pin-compatible with other K11 family members?

No, the MK11DN512VLK5 is not universally pin-compatible across the K11 family. While it shares the 80-pin LQFP (LK) package with other LK-suffixed variants (e.g., MK11DX256VLK5), pin functions differ based on peripheral enablement and memory configuration. For example, FlexNVM-related signals (FTFL_FLEXRAM, FTFL_FLEXNVM) present on MK11DX parts are unconnected or repurposed on the MK11DN512VLK5. Always verify signal mapping using the K11 Pin Assignments table in the datasheet.
