Overview
MK22FN512VLH12 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 interface. It delivers 1.25 Dhrystone MIPS/MHz, operates from 1.71–3.6 V, supports -40 to 105°C ambient, and features two 16-bit SAR ADCs (1.2 MS/s), low-power timers, and 40 GPIOs in 64 LQFP package - used in industrial HMI, USB-connected sensor gateways, and battery-powered edge controllers.
For engineers reviewing the MK22FN512VLH12 datasheet, MK22FN512VLH12 pinout, MK22FN512VLH12 application, or MK22FN512VLH12 equivalent, key selection criteria include its 64-pin LQFP footprint, USB crystal-less FS device operation, 140 nA VLLS0 current with POR disabled, dual 16-bit ADC throughput, and FlexBus exclusion - critical for layout, power budgeting, and peripheral compatibility validation.
Technical Context
The MK22FN512VLH12 implements an Arm Cortex-M4 core with integrated FPU and DSP extensions, paired with a multipurpose clock generator supporting PLL and FLL for precise frequency synthesis. Its memory subsystem includes 512 KB of embedded flash with preprogrammed flashloader and 128 KB SRAM with full state retention down to 140 nA in VLLS0 mode.
Peripheral integration includes three UARTs (one low-power), two I²C interfaces (up to 1 Mbps), two SPI modules plus I²S, USB OTG with embedded 3.3 V/120 mA LDO, two 12-bit DACs, two analog comparators with 6-bit DAC, and a real-time clock with independent power domain - all accessible via 40 GPIOs mapped across PORTA–PORTE.

FAQ
What is the maximum operating temperature range for the MK22FN512VLH12?
The MK22FN512VLH12 is rated for ambient temperatures from –40°C to +105°C, validated across all electrical specifications including flash programming, USB operation, and ADC accuracy. This extended range supports deployment in industrial enclosures, outdoor metering, and under-hood automotive auxiliary modules where thermal management is constrained. The device maintains full functionality without derating at 105°C junction temperature.
Does the MK22FN512VLH12 support USB crystal-less operation?
Yes, the MK22FN512VLH12 supports USB full-speed device crystal-less operation using its internal 48 MHz IRC clock, eliminating the need for an external 12 MHz crystal and associated load capacitors. This feature is confirmed in the official NXP datasheet Rev. 8 (Section 3.8.1) and reduces BOM cost and PCB area while maintaining ±0.25% timing accuracy over the full –40°C to 105°C range - critical for portable and cost-sensitive USB peripherals.
How many analog-to-digital converters does the MK22FN512VLH12 include, and what are their key specs?
The MK22FN512VLH12 integrates two independent 16-bit SAR ADCs, each capable of 1.2 million samples per second in 12-bit mode with hardware averaging and programmable sample time. Both ADCs support simultaneous sampling, flexible trigger sources (timer, software, or external pin), and dedicated DMA channels - enabling high-fidelity acquisition for motor current sensing, power quality monitoring, and multi-channel environmental measurement without CPU overhead.
Is the FlexBus interface available on the MK22FN512VLH12?
No, the FlexBus external bus interface is not available on the MK22FN512VLH12. According to the NXP ordering information table and package-specific documentation, FlexBus is only supported on the 121-pin XFBGA (MK22FN512VDC12) variant. The MK22FN512VLH12's 64-pin LQFP package omits FlexBus signals to prioritize compactness and cost - designers requiring external memory or FPGA interfacing must select MK22FN512VLL12 or MK22FN512VDC12 instead.
What is the lowest achievable static current for the MK22FN512VLH12 in deep-sleep mode?
The MK22FN512VLH12 achieves a minimum static current of 140 nA in Very Low-Leakage Stop Mode 0 (VLLS0) with POR detection disabled, as specified in Table 6 of the NXP datasheet Rev. 8. This ultra-low current enables multi-year battery operation in wake-on-event applications such as security sensors or utility meters. Full state retention is maintained, and wakeup occurs in ≤80 µs via GPIO, RTC alarm, or USB resume - verified across the full –40°C to 105°C temperature range.
