NXP Semiconductors MK22FN128VLH10

Overview

MK22FN128VLH10 from NXP (formerly Freescale) is a 100 MHz ARM® Cortex®-M4 microcontroller with 128 KB flash, 24 KB SRAM, and 4-channel DMA, housed in a 64-pin LQFP package. It integrates dual 16-bit ADCs (14 SE + 2 DP inputs each), one 12-bit DAC, USB OTG LS/FS (device-only), three UARTs (including ISO7816 support), two I²C, two SPI, and programmable analog comparators - designed for industrial sensor nodes and low-power HMI control systems.

For engineers reviewing the MK22FN128VLH10 datasheet, MK22FN128VLH10 pinout, MK22FN128VLH10 application, or MK22FN128VLH10 equivalent, key selection considerations include its 100 MHz Cortex-M4 core with single-precision FPU, 1.71–3.6 V operation, -40°C to +105°C temperature range, and support for VLPS/LLS/VLLS ultra-low-power stop modes with RTC, LPTimer, CMP, and DAC retention.

Technical Context

The MK22FN128VLH10 implements a Harvard-architecture Cortex-M4 core with DSP extensions and single-precision floating-point unit, operating at 100 MHz with 1.25 DMIPS/MHz performance. Its system clocking supports FLL (with 32 kHz internal/external reference) and optional PLL (not enabled in 128 KB variants), while power management includes PMC-controlled run, wait, and six deep-sleep modes (VLPS, LLS3, VLLS3–VLLS0).

Analog subsystems include two independent 16-bit ADC modules (ADC0/ADC1), each with configurable resolution (8–16 bit), hardware averaging, temperature sensor, and asynchronous clocking; plus one 12-bit DAC with automatic waveform generation (square/triangle/sawtooth), DMA support, and 1 µs high-speed conversion. Communication is served by three UARTs (one with ISO7816), two I²C, two DSPI, one I²S, and USB OTG LS/FS in device-only mode.

FAQ

Does MK22FN128VLH10 support USB host functionality?

No, MK22FN128VLH10 supports USB OTG LS/FS in device-only mode per the K22F Family Product Brief. Host mode is explicitly excluded for 128 KB flash variants - only 256 KB and 512 KB devices (e.g., MK22FN256VLL12) include USB host capability. The MK22FN128VLH10 USB module connects exclusively as a peripheral to a host PC or embedded controller.

What is the maximum ADC sampling rate achievable with MK22FN128VLH10?

The MK22FN128VLH10 supports up to 1 MSPS (mega-samples per second) per ADC module under optimal conditions: 12-bit resolution, shortest sample time, and bus clock ≥ 50 MHz. With its 100 MHz core clock and 50 MHz bus clock, both ADC0 and ADC1 can operate concurrently at this rate - enabling true dual-channel synchronous acquisition for applications like motor phase current sensing.

Can MK22FN128VLH10 enter VLLS0 mode with RTC alarm wake-up enabled?

Yes, MK22FN128VLH10 supports VLLS0 mode with RTC alarm wake-up active. In VLLS0, all SRAM is powered off except the 32-byte VBAT register file and system register file, yet the RTC remains functional using its dedicated 32 kHz oscillator and VBAT supply. An RTC alarm event triggers a wakeup reset, restoring full operation while preserving critical VBAT-stored data.

Is the 12-bit DAC on MK22FN128VLH10 capable of generating arbitrary waveforms?

The MK22FN128VLH10's 12-bit DAC supports predefined waveforms (square, triangle, sawtooth) in automatic mode with programmable period and amplitude, but does not support arbitrary waveform generation via DMA or buffer streaming. For custom waveforms, external DMA-driven updates to DAC data registers are required - limited by 1 µs high-speed conversion time and available bus bandwidth.

Does MK22FN128VLH10 include hardware cryptographic acceleration?

No, MK22FN128VLH10 does not include dedicated cryptographic accelerators (e.g., AES, SHA, RNG). Security relies on flash protection mechanisms, memory isolation, and software-implemented algorithms. For hardware crypto, consider NXP's K32W0x or LPC55Sxx families - the MK22FN128VLH10 prioritizes analog integration and ultra-low-power operation over cryptographic throughput.
