Product details
Overview
MK22FN128VLL10 from NXP (formerly Freescale) is an ARM Cortex-M4 microcontroller with 100 MHz CPU frequency, 128 KB flash, 24 KB SRAM, and 100-pin LQFP package. It integrates a single-precision FPU, dual 16-bit ADCs (19+4 SE/DP channels), one 12-bit DAC, three UARTs (including ISO7816 support), two I²C, two SPI, USB OTG LS/FS device-only interface, and programmable FlexTimers - deployed in industrial sensor nodes requiring deterministic real-time control and low-power operation.
For engineers reviewing the MK22FN128VLL10 datasheet, MK22FN128VLL10 pinout, MK22FN128VLL10 application, or MK22FN128VLL10 equivalent, key selection criteria include its 100 MHz Cortex-M4 core with FPU, 100-pin LQFP footprint, USB device-only capability, 4-channel DMA, and support for VLPS/VLLS low-power modes down to 1.8 µA - critical for battery-powered edge controllers and HMI subsystems.
Technical Context
The MK22FN128VLL10 implements a Harvard-architecture ARM Cortex-M4 core with single-precision floating-point unit and DSP extensions, operating at up to 100 MHz with 1.25 DMIPS/MHz performance. Its system-level timing relies on a configurable MCG module supporting FLL and optional PLL (not present in this 128 KB variant), with internal 48 MHz IRC and 32 kHz RTC oscillator.
Peripheral integration includes two 16-bit ADCs with differential input support, one 12-bit DAC with automatic waveform generation, FlexTimer modules supporting PWM, quadrature decoding, and dead-time insertion, plus USB OTG LS/FS transceiver operating exclusively in device mode - all coordinated via NVIC with up to 120 interrupt sources and 16 priority levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M4 with single-precision FPU and DSP instructions - enables real-time signal processing without external coprocessor. |
| Max Clock Frequency | 100 MHz - defines maximum instruction throughput and peripheral clock domain limits for UART baud rates, ADC sampling, and PWM resolution. |
| Flash / RAM | 128 KB flash / 24 KB SRAM - sufficient for RTOS-based firmware with protocol stacks (USB CDC, Modbus) and local data buffering. |
| ADC | Dual 16-bit SAR ADCs: ADC0 with 19 SE + 4 DP inputs, ADC1 with 19 SE + 3 DP inputs - supports simultaneous analog sensing of multiple sensors with noise rejection. |
| USB Interface | USB OTG LS/FS transceiver in device-only mode - enables direct connection to host PCs or embedded hosts without external PHY; no host capability. |
| Low-Power Modes | VLPS (4.2 µA), VLLS3 (1.8 µA), VLLS0 (150 nA with POR disabled) - allows multi-year battery life in wake-on-interrupt sensor applications. |
| DMA Channels | 4-channel DMA controller - offloads CPU from memory-mapped peripheral transfers (e.g., ADC-to-SRAM, UART TX/RX buffers). |
Pinout & Package
Package: 100-pin LQFP (VLL suffix), 14 × 14 mm body, 0.5 mm pitch, exposed thermal pad. Compatible with standard reflow profiles and manual soldering under IPC-J-STD-020D.2 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PTA0–PTA31 | GPIO Port A signals | 32-bit general-purpose I/O bank with digital filter, interrupt capability, and alternate function mapping to UART0, I²C0, SPI0, FTM0, etc. |

| PTC0–PTC16 | GPIO Port C signals | 17-bit GPIO bank with ADC1 inputs, FTM2, SPI1, LPUART0, and PDB trigger outputs. |
| VDD/VSS (x12) | Power supply / ground | Distributed power pins ensure stable core/peripheral voltage delivery; VDDA/VSSA dedicated for analog circuitry reduce noise coupling. |
| USB_DP / USB_DM | USB differential pair | On-die full-speed (12 Mbps) transceiver I/O - requires 27 Ω series resistors and 1.5 kΩ pull-up on DP for device enumeration. |
| RTC_CLKIN | 32.768 kHz crystal input | Connects to external tuning fork crystal for independent RTC operation during VBAT backup or deep-sleep modes. |
Key Features
| Feature | Design Value |
|---|---|
| Very Low Leakage Stop (VLLS0) | 150 nA current draw with POR disabled - enables decade-scale battery operation in maintenance-free IoT endpoints. |
| Programmable Delay Block (PDB) | Hardware-triggered ADC sampling with sub-microsecond jitter - synchronizes analog acquisition to motor commutation or PWM edges. |
| FlexTimer Quadrature Decoder | Hardware position counting with input filtering and interrupt on count threshold - eliminates CPU polling for encoder-based motion control. |
| 12-bit DAC with auto-waveform mode | Generates triangle/sawtooth/square waveforms without CPU intervention - simplifies analog test signal generation in calibration equipment. |

FAQ
Does MK22FN128VLL10 support USB host functionality?
No, MK22FN128VLL10 implements USB OTG LS/FS transceiver in device-only mode per its 128 KB flash configuration. Host capability is reserved for 256 KB and 512 KB variants (e.g., MK22FN256VLL12). The MK22FN128VLL10 supports CDC, HID, and MSC device classes via on-chip PHY without external components.
What is the maximum ADC sampling rate achievable with MK22FN128VLL10?
With ADC0 configured for 12-bit single-ended mode and 25 MHz bus clock, MK22FN128VLL10 achieves up to 1.2 MS/s conversion rate. Actual sustained rate depends on PGA gain setting, sample time, and synchronous vs. asynchronous clock selection - verified in the K22F reference manual section 36.5.1.
Can MK22FN128VLL10 operate from a single 3.3 V supply across all peripherals?
Yes, MK22FN128VLL10 operates from 1.71–3.6 V supply range. All digital I/O, analog modules (ADC/DAC/CMP), and USB transceiver function correctly at 3.3 V nominal. VDDA must be tied to same 3.3 V rail with dedicated 100 nF decoupling; no separate analog regulator is required.
How many independent PWM outputs does MK22FN128VLL10 support?
MK22FN128VLL10 integrates FlexTimer Module (FTM) instances supporting up to 8 independent PWM outputs: FTM0 provides 8 channels, FTM1 offers 2 channels, and FTM2 supplies 2 channels - configurable in edge-aligned or center-aligned mode with programmable dead-time insertion on complementary pairs.
Is there hardware support for cryptographic operations in MK22FN128VLL10?
No, MK22FN128VLL10 does not include dedicated cryptographic accelerators (AES/SHA/RNG). Security relies on software libraries and memory protection unit (MPU) enforcement. For hardware crypto, consider NXP's K32W042 or i.MX RT series - MK22FN128VLL10 prioritizes real-time analog control over encryption throughput.
