Product details
Overview
MK11DN512AVLK5 from NXP Semiconductors (formerly Freescale) is a 50 MHz ARM Cortex-M4 core microcontroller with DSP instructions, 512 KB program flash, 64 KB RAM, and integrated analog peripherals including 16-bit SAR ADC, 12-bit DAC, and two analog comparators. It operates from 1.71–3.6 V across –40 to 105°C and targets industrial motor control and sensor-edge applications requiring deterministic real-time response.
For engineers reviewing the MK11DN512AVLK5 datasheet, MK11DN512AVLK5 pinout, MK11DN512AVLK5 application, or MK11DN512AVLK5 equivalent, key selection considerations include its FlexMemory-free flash configuration, 80-pin LQFP package, USB Device Charger Detect support, low-power stop modes down to 0.36 µA, and hardware cryptographic acceleration for AES/SHA-256.
Technical Context
The MK11DN512AVLK5 implements an ARM Cortex-M4 core with DSP extensions and no FPU, executing at up to 50 MHz with 1.25 DMIPS/MHz performance. Its clock system includes dual crystal oscillators (3–32 MHz and 32 kHz), a multi-purpose clock generator, and configurable MCG modes supporting FEI, FBE, and BLPE for flexible power/performance trade-offs.
System-level integration includes an 8-channel motor control/PWM timer, two 2-channel general-purpose timers (one with quadrature decoder), RTC, carrier modulator transmitter, and eight communication interfaces: four UARTs, two SPIs, two I²Cs, one I²S, and USB Device Charger Detect - all operating within the same voltage and temperature envelope.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK11DN512VLK5 | Same core, flash, RAM, and peripherals; differs only in temperature grade (–40 to 85°C vs. –40 to 105°C). | Suitable for commercial-grade equipment where ambient temperature remains below 85°C. | Select MK11DN512VLK5 when extended temperature operation is unnecessary and cost optimization is prioritized. |
| MKE15Z64VLD4 | ARM Cortex-M0+ core, 64 KB flash, 8 KB RAM, no hardware crypto, lower max frequency (48 MHz), but enhanced analog precision (16-bit ADC with PGA). | Better suited for ultra-low-cost, analog-intensive applications like portable instrumentation where DSP is not required. | Choose MKE15Z64VLD4 when deterministic low-latency analog acquisition outweighs computational throughput and security needs. |
Compared with MK11DN512VLK5, the MK11DN512AVLK5 adds extended temperature capability essential for under-hood automotive or industrial enclosures; versus MKE15Z64VLD4, it trades analog gain flexibility for DSP performance, hardware crypto, and larger memory - making it optimal for secure, compute-heavy edge nodes.

FAQ
What is the maximum operating frequency of the MK11DN512AVLK5?
The MK11DN512AVLK5 features an ARM Cortex-M4 core rated for up to 50 MHz operation. This frequency is supported across the full –40 to 105°C temperature range and 1.71–3.6 V supply voltage, with flash execution at zero wait states when the flash clock is configured to 25 MHz. The MK11DN512AVLK5 achieves 1.25 Dhrystone MIPS per MHz, delivering deterministic real-time performance for motor control and sensor processing tasks.
Does the MK11DN512AVLK5 include hardware cryptographic acceleration?
Yes, the MK11DN512AVLK5 integrates dedicated hardware accelerators for DES, 3DES, AES (128/192/256-bit), MD5, SHA-1, and SHA-256 algorithms. These modules operate independently of the CPU, enabling secure boot verification, firmware signature checking, and encrypted data logging without compromising real-time responsiveness. The MK11DN512AVLK5 also includes a hardware random-number generator and tamper-detect circuitry for comprehensive security implementation.
What low-power modes are supported by the MK11DN512AVLK5?
The MK11DN512AVLK5 supports seven low-power modes: RUN, WAIT, STOP, VLPR, VLPW, VLPS, and four Very-Low-Leakage Stop (VLLS0–VLLS3) modes. In VLLS0 with POR detect disabled, the MK11DN512AVLK5 draws just 0.36 µA at 3.0 V and 25°C, retaining RAM and selected registers. Wakeup sources include GPIO, RTC alarm, analog comparator output, and LPTMR - all configurable to trigger from deepest sleep states without CPU intervention.
What analog peripherals are integrated into the MK11DN512AVLK5?
The MK11DN512AVLK5 integrates a 16-bit SAR ADC with up to 16 single-ended or 8 differential inputs, a 12-bit DAC with programmable output range, two analog comparators each featuring a 6-bit DAC and programmable reference input, and a precision voltage reference module. These peripherals are powered by a dedicated VDDA/VSSA domain with strict ±0.1 V differential tolerance, ensuring high-accuracy measurements for current sensing, voltage monitoring, and closed-loop control in the MK11DN512AVLK5.
Is the MK11DN512AVLK5 pin-compatible with other K11 family members?
The MK11DN512AVLK5 uses an 80-pin LQFP (LK package) footprint shared across multiple K11 variants including MK11DX256VLK5 and MK11DN512VLK5. Pin assignments for power, reset, clocks, USB, and major peripherals are consistent within the LK package group. However, peripheral multiplexing varies by flash size and feature set - for example, FlexNVM-capable devices assign certain pins to FlexRAM control, while the MK11DN512AVLK5 (flash-only) reallocates those pins to GPIO or alternate functions. Always verify signal mapping against the specific MK11DN512AVLK5 pinout table.
