Product details
Overview
MK22FN512VFX12 from NXP Semiconductors is a 120 MHz Arm® Cortex®-M4 microcontroller with FPU, 512 KB flash, 128 KB RAM, and USB LS/FS OTG 2.0 support - delivered in an 88-pin QFN (10 × 10 × 0.9 mm, 0.4 mm pitch). It operates from 1.71–3.6 V across –40 to 105°C and delivers 156 µA/MHz active power consumption. It targets low-power industrial control and USB-connected edge sensor nodes requiring deterministic real-time response.
For engineers reviewing the MK22FN512VFX12 datasheet, MK22FN512VFX12 pinout, MK22FN512VFX12 application, or MK22FN512VFX12 equivalent, key selection criteria include its 88-QFN package footprint, absence of FlexBus interface, full USB crystal-less device mode, dual 16-bit SAR ADCs (1.2 MS/s), and verified low-leakage stop modes down to 0.14 µA (VLLS0, POR disabled).
Technical Context
The MK22FN512VFX12 implements a single-core Arm Cortex-M4 with integrated FPU and DSP extensions, clocked up to 120 MHz via PLL/FLL-based multipurpose clock generator. Its memory subsystem includes 512 KB of on-chip flash with preprogrammed flashloader and 128 KB SRAM with full state retention in low-power modes.
It integrates two 16-bit SAR ADCs (1.2 MS/s at 12-bit), two analog comparators with embedded 6-bit DACs, and one low-power UART alongside three standard UARTs, two I²C interfaces (up to 1 Mbps), two SPI modules, and I²S. USB OTG 2.0 includes an embedded 3.3 V/120 mA LDO and supports crystal-less full-speed device operation - but excludes FlexBus functionality per ordering-row specification.

FAQ
Does MK22FN512VFX12 support the FlexBus external bus interface?
No. Per the official ordering-row specification, MK22FN512VFX12 (88QFN) does not support the FlexBus function. This exclusion is package-specific and confirmed in NXP's K22F documentation - other variants like MK22FN512VDC12 retain FlexBus capability. Designers must rely on SPI, I²C, or USB for external peripheral interfacing with MK22FN512VFX12.
What is the maximum operating temperature range for MK22FN512VFX12?
The MK22FN512VFX12 is rated for –40 to 105°C ambient temperature, meeting industrial-grade thermal requirements. This specification is validated across all electrical parameters in the datasheet, including ADC accuracy, USB timing, and low-power mode currents - enabling reliable deployment in control cabinets, outdoor sensors, and factory-floor equipment without thermal derating.
Can MK22FN512VFX12 operate USB in crystal-less mode?
Yes. MK22FN512VFX12 supports USB full-speed device crystal-less operation using its internal oscillator, eliminating the need for an external 12 MHz crystal and associated load capacitors. This feature is explicitly documented in the K22F datasheet and reduces BOM cost and PCB layout complexity - critical for space-constrained USB peripherals like diagnostic tools or HID devices.
How many analog-to-digital converters does MK22FN512VFX12 include?
MK22FN512VFX12 integrates two independent 16-bit SAR ADCs, each capable of 1.2 million samples per second in 12-bit mode. Both ADCs support hardware triggering, DMA transfer, and flexible input multiplexing - enabling simultaneous voltage/current sensing or multi-channel sensor acquisition without external ADCs.
What is the lowest power consumption mode available on MK22FN512VFX12?
The lowest power mode on MK22FN512VFX12 is Very Low-Leakage Stop Mode 0 (VLLS0) with POR detect circuit disabled, achieving 0.14 µA typical current at 3.0 V and –40 to 25°C. This mode retains full SRAM and register contents while allowing wake-up via RTC alarm, GPIO, or comparator - ideal for battery-powered endpoints requiring multi-year operation.
