Product details
Overview
MK11DX128VLK5 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, designed for embedded control in industrial and automotive applications. It operates at up to 50 MHz, integrates 128 KB program flash with FlexMemory, 64 KB RAM, and supports -40°C to +105°C ambient operation with 1.71–3.6 V supply voltage.
For engineers reviewing the MK11DX128VLK5 datasheet, MK11DX128VLK5 pinout, MK11DX128VLK5 application, or MK11DX128VLK5 equivalent, this page delivers verified electrical specs, package mapping, low-power mode behavior, analog peripheral capabilities (16-bit SAR ADC, dual comparators), and USB/UART/I²C/SPI interface configuration details essential for real-time control and secure firmware deployment.
Technical Context
The MK11DX128VLK5 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC, enabling deterministic signal processing in motor control and sensor fusion. Its clock system includes 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-32 accelerator, tamper-detect circuitry, true random-number generator, and cryptographic engines for DES, 3DES, AES, MD5, SHA-1, and SHA-256 - all operating independently of CPU execution. Memory subsystem features EzPort serial programming interface and FlexNVM architecture allowing runtime reconfiguration of 4 KB FlexRAM and 64 KB FlexNVM as EEPROM-emulation or data flash.
Key Specifications

FAQ
What is the maximum operating frequency of the MK11DX128VLK5?
The MK11DX128VLK5 operates at a maximum core/system clock frequency of 50 MHz, as specified in the K11 Sub-Family Data Sheet Rev. 4.1. This frequency is achievable across the full -40°C to +105°C temperature range when supplied with 1.71–3.6 V, and is supported by the on-chip MCG clock generator in FEI or PEE modes. The MK11DX128VLK5 maintains timing compliance without derating under these conditions.
Does the MK11DX128VLK5 include hardware cryptographic acceleration?
Yes, the MK11DX128VLK5 integrates dedicated hardware modules supporting DES, 3DES, AES (128/192/256-bit), MD5, SHA-1, and SHA-256 cryptographic operations. These accelerators operate independently of the Cortex-M4 core, enabling concurrent encryption/decryption and hash computation without CPU intervention - a confirmed feature documented in Section 5.5 of the K11P80M50SF4 datasheet.
What package type does the MK11DX128VLK5 use?
The MK11DX128VLK5 uses an 80-pin LQFP package (12 mm × 12 mm), identified by the "LK" suffix in its part number per the K11 family naming convention. This package is RoHS-compliant, lead-free, and rated at Moisture Sensitivity Level 3 (MSL3) per J-STD-020 - confirmed in Section 2.3 and Table 7 of the K11 Sub-Family Data Sheet Rev. 4.1.
How much FlexMemory does the MK11DX128VLK5 provide?
The MK11DX128VLK5 provides 64 KB of FlexNVM and 4 KB of FlexRAM, as explicitly stated in the "Memories and memory interfaces" section of the K11P80M50SF4 datasheet. This FlexMemory configuration is fixed for the "X" variant (Cortex-M4 with FlexMemory) and enables EEPROM-emulation functionality with byte-write capability and 100,000-cycle endurance - verified in Section 6.4.1.
Is the MK11DX128VLK5 pin-compatible with other K11 family members?
The MK11DX128VLK5 shares the same 80-pin LQFP (LK) package footprint and pin assignment with MK11DX256VLK5 and MK11DN512VLK5, as confirmed in Section 8.2 "K11 Pinouts" of the K11 Sub-Family Data Sheet Rev. 4.1. However, functional differences exist in flash/FlexNVM size and some peripheral enablement - so while PCB layout is reusable, firmware and power design must be validated per specific variant.
