NXP Semiconductors MK22DN512VLK5

Overview

MK22DN512VLK5 from NXP Semiconductors (formerly Freescale) is a 50 MHz ARM Cortex-M4 core microcontroller with DSP instructions, 512 KB on-chip program flash memory, 64 KB RAM, and integrated USB OTG, ADC, DAC, and multiple low-power timer modules. It operates from 1.71–3.6 V across –40 to 105°C and targets industrial motor control, sensor fusion, and USB-connected embedded systems.

For engineers reviewing the MK22DN512VLK5 datasheet, MK22DN512VLK5 pinout, MK22DN512VLK5 application, or MK22DN512VLK5 equivalent, key selection considerations include its FlexMemory absence (flash-only configuration), 80-pin LQFP package, 16-bit SAR ADC with 12-bit DAC support, USB full-/low-speed On-The-Go capability, and multi-mode power management for battery-sensitive designs.

Technical Context

The MK22DN512VLK5 implements an ARM Cortex-M4 core with hardware DSP extensions and no FPU, executing up to 50 MHz with 1.25 Dhrystone MIPS/MHz. Its clock system includes dual crystal oscillators (3–32 MHz and 32 kHz), a multi-purpose clock generator, and MCG modes supporting FEI, FBE, and BLPE configurations for dynamic frequency/power trade-offs.

Peripherals are organized around a 16-channel DMA controller, eight-channel PWM timer, two 2-channel general-purpose timers (one with quadrature decoder), real-time clock, carrier modulator transmitter, and communication interfaces including four UARTs, two SPIs, two I²Cs, one I²S, and USB OTG with on-chip transceiver and charger detect.

FAQ

What is the maximum operating frequency of the MK22DN512VLK5?

The MK22DN512VLK5 operates at a maximum core and system clock frequency of 50 MHz. This is achieved using the internal PLL driven by the main crystal oscillator (3–32 MHz) or internal reference, and it remains stable across the full –40 to 105°C temperature range and 1.71–3.6 V supply voltage. The MK22DN512VLK5 does not support frequencies above 50 MHz, as confirmed by its '5' suffix in the part number and the K22P80M50SF4 datasheet revision 4.1.

Does the MK22DN512VLK5 include FlexMemory (FlexNVM/FlexRAM)?

No, the MK22DN512VLK5 does not include FlexMemory. Its part number encoding confirms this: the 'N' in position 5 indicates "program flash only", distinguishing it from 'X' variants like MK22DX512VLK5 which integrate FlexNVM and FlexRAM. Therefore, the MK22DN512VLK5 provides 512 KB of program flash and 64 KB of RAM, with no user-reconfigurable EEPROM-like storage or additional FlexRAM.

What USB capabilities does the MK22DN512VLK5 support?

The MK22DN512VLK5 integrates a full-/low-speed USB On-The-Go controller with an on-chip transceiver and USB Device Charger Detect (DCD) functionality. It supports both device and host roles without external PHY components, and the DCD feature enables automatic detection of standard downstream ports, charging ports, and dedicated chargers - essential for portable USB-powered applications using the MK22DN512VLK5.

Which package type is used for the MK22DN512VLK5?

The MK22DN512VLK5 uses an 80-pin LQFP package with 12 mm × 12 mm body size and 0.5 mm pitch, designated by the 'LK' suffix in its part number. This package provides high I/O count and thermal performance suitable for industrial control applications, and is distinct from smaller QFN or BGA variants in the K22 family. Pin assignments and mechanical dimensions are fully documented in Section 8 of the K22P80M50SF4 datasheet.

What are the supported low-power modes on the MK22DN512VLK5?

The MK22DN512VLK5 supports seven low-power modes: RUN, WAIT, STOP, VLPR/VLPW/VLPS, LLS, and VLLS0–VLLS3. In VLLS0 mode with POR detect disabled, it achieves as low as 0.36 μA at –40°C. These modes are controlled via the System Integration Module (SIM) and Power Management Controller (PMC), and each offers different combinations of clock gating, peripheral retention, and wake-up sources - enabling fine-grained power optimization in battery-operated MK22DN512VLK5 deployments.
