Overview

MK22FN128VLH10 from NXP Semiconductors is a 100 MHz ARM® Cortex®-M4 microcontroller with FPU, 128 KB flash, 24 KB RAM, and 40 GPIOs in 64-pin LQFP package. It integrates USB LS/FS OTG 2.0 with crystal-less device operation, dual 16-bit SAR ADCs (1.2 MS/s), and low-power modes down to 120 nA - deployed in industrial sensor nodes requiring USB connectivity and deterministic real-time control.

For engineers reviewing the MK22FN128VLH10 datasheet, MK22FN128VLH10 pinout, MK22FN128VLH10 application, or MK22FN128VLH10 equivalent, key selection criteria include USB crystal-less support, VLLS0 static current (0.12–0.49 µA), 100 MHz FPU-enabled compute throughput, and 64-pin LQFP thermal/mechanical compatibility with legacy Kinetis designs.

Technical Context

The MK22FN128VLH10 implements a multi-clock architecture with three internal oscillators (32 kHz, 4 MHz, 48 MHz), two crystal inputs (32 kHz RTC + 3–32 MHz main), and a multipurpose clock generator with FLL for frequency synthesis. Its power management includes seven low-power modes (VLPx, LLS, VLLS) with configurable wakeup sources and sub-µA retention states.

Peripherals are organized around a 4-channel DMA controller, independent watchdogs, hardware CRC, and programmable delay block. Analog subsystem comprises two 16-bit SAR ADCs with simultaneous sampling capability, one 12-bit DAC, two analog comparators with integrated 6-bit DACs, and an accurate internal voltage reference - all operating across –40°C to 105°C ambient.

FAQ

What is the maximum operating frequency and core type of the MK22FN128VLH10?

The MK22FN128VLH10 features a 100 MHz ARM Cortex-M4 core with integrated floating-point unit (FPU). It delivers 1.25 Dhrystone MIPS per MHz and supports DSP instructions for efficient signal processing. This performance level is sustained across its full operating voltage range (1.71–3.6 V) and temperature range (–40°C to 105°C), making MK22FN128VLH10 suitable for deterministic real-time control tasks in industrial environments.

Does the MK22FN128VLH10 support crystal-less USB Full-Speed device operation?

Yes, the MK22FN128VLH10 supports USB Full-Speed (12 Mbps) device mode without an external crystal, using its internally trimmed 48 MHz IRC oscillator with ±0.25% accuracy. This feature eliminates the need for a 12 MHz crystal and associated load capacitors, reducing BOM cost and PCB area. The USB OTG 2.0 peripheral includes an on-chip transceiver and complies with USB 2.0 specifications - confirmed in MK22FN128VLH10's official datasheet Rev. 7, Section 3.8.1.

How many GPIOs does the MK22FN128VLH10 provide, and what are their key electrical characteristics?

The MK22FN128VLH10 provides 40 general-purpose I/O pins in its 64-pin LQFP package. Each GPIO supports configurable pull-up/pull-down (20–50 kΩ), programmable slew rate, and interrupt-on-change. High-drive capability (20 mA sink/source) is available on selected pins (e.g., PTB0, PTB1, PTC3–PTC4). Input leakage is ≤0.5 µA per pin, and output drive strength meets VOH ≥ VDD – 0.5 V and VOL ≤ 0.5 V under specified load conditions - verified per datasheet Table 4.

What are the lowest power consumption modes supported by the MK22FN128VLH10?

The MK22FN128VLH10 supports Very Low-Leakage Stop (VLLS) modes, with VLLS0 drawing as low as 0.12 µA (at –40°C to 25°C, POR disabled) while retaining full register state and enabling 6 µs wakeup. VLLS1 draws 0.70–4.0 µA depending on temperature and configuration. These modes use separate power domains for RTC and memory retention, and are validated per datasheet Table 6 - making MK22FN128VLH10 appropriate for battery-powered applications requiring multi-year operation.

Which analog peripherals are integrated into the MK22FN128VLH10, and what are their key specs?

The MK22FN128VLH10 integrates two 16-bit SAR ADCs (1.2 MS/s in 12-bit mode), one 12-bit DAC, two analog comparators with integrated 6-bit DACs, and an accurate internal voltage reference. ADCs support simultaneous sampling and hardware averaging; the DAC provides monotonic output with ±1 LSB INL. All analog modules operate across the full –40°C to 105°C range and are powered from dedicated VDDA/VSSA rails - specifications confirmed in datasheet Sections 3.6.1–3.6.4.
