NXP Semiconductors MK11DX128VMC5

Overview

MK11DX128VMC5 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extension and optional single-precision FPU, operating at 50 MHz. It integrates 128 KB flash, 64 KB FlexNVM (emulating EEPROM), 32 KB SRAM, 16-bit ADC, 12-bit DAC, programmable gain amplifier, and dual CAN interfaces. It targets low-power industrial sensing and control applications including flow meters and remote sensors.

For engineers reviewing the MK11DX128VMC5 datasheet, MK11DX128VMC5 pinout, MK11DX128VMC5 application, or MK11DX128VMC5 equivalent, key selection considerations include its 50 MHz Cortex-M4 core with hardware cryptographic acceleration (CAU), tamper detection unit, 10 ultra-low-power modes (<500 nA Stop current), and 32-pin 5×5 mm QFN package with 5 V-tolerant I/O.

Technical Context

The MK11DX128VMC5 implements an ARM Cortex-M4 core with DSP instruction set and optional single-precision floating-point unit. It supports concurrent flash execution and firmware updates via independent flash banks and includes a memory protection unit (MPU) for secure code isolation.

Its analog subsystem features a 16-bit ADC with PGA, 12-bit DAC, and on-chip voltage reference-enabling high-accuracy signal conditioning without external components. The device integrates a cryptographic acceleration unit (CAU) supporting AES, SHA-1/256, and DES/3DES, plus a hardware tamper detection unit for secure key storage.

FAQ

What is the maximum operating frequency of the MK11DX128VMC5?

The MK11DX128VMC5 operates at a maximum core frequency of 50 MHz. This is fixed for this variant-unlike higher-grade K1x members (e.g., MK10DX128Vyy7), which support 72 MHz. The 50 MHz speed balances processing performance with ultra-low-power operation, enabling sub-200 µA/MHz active current and <500 nA Stop mode current in the MK11DX128VMC5.

Does the MK11DX128VMC5 include hardware cryptographic acceleration?

Yes, the MK11DX128VMC5 integrates a Cryptographic Acceleration Unit (CAU) supporting AES-128/256, SHA-1/256, DES, and 3DES. This hardware engine offloads crypto operations from the Cortex-M4 core, reducing execution time by >90% versus software-only implementations-critical for secure boot, OTA firmware updates, and encrypted sensor data transmission in the MK11DX128VMC5.

What package type and pin count does the MK11DX128VMC5 use?

The MK11DX128VMC5 uses a 32-pin QFN package measuring 5 mm × 5 mm with 0.5 mm pitch. The "MC" in the part number explicitly denotes this 32-QFN variant. It provides 26 GPIOs (including 5 V-tolerant pins), dual CAN transceivers, USB, ADC, DAC, and touch-sensing interfaces-all in a compact footprint ideal for space-constrained industrial modules.

How much FlexMemory is available on the MK11DX128VMC5, and how is it allocated?

The MK11DX128VMC5 includes 64 KB of FlexNVM, configurable as either program/data flash or EEPROM emulation. Up to 16 KB can be allocated as byte-erasable, byte-writable EEPROM-ideal for storing calibration data, device IDs, or usage counters without wearing main flash. The remaining FlexNVM serves as additional code or data space, and this allocation is set at runtime via FTFA commands in the MK11DX128VMC5.

Is the MK11DX128VMC5 pin-compatible with other Kinetis K1x MCUs in the same package?

Yes, the MK11DX128VMC5 shares identical pinout and footprint with other 32-QFN K1x variants including MK10DX128VLC5 and MK11DX256AVMC5. This enables direct substitution within the same PCB layout-though firmware must be validated for peripheral differences (e.g., CAU presence, FlexNVM size). Pin compatibility simplifies migration and portfolio management across the MK11DX128VMC5 family.
