NXP Semiconductors MK22FN1M0VLL12

Overview

MK22FN1M0VLL12 from NXP Semiconductors (formerly Freescale) is a 120 MHz ARM Cortex-M4 microcontroller with FPU, 1 MB flash, 128 KB SRAM, and USB LS/FS OTG 2.0 with integrated 3.3 V/120 mA LDO regulator. It delivers 1.25 Dhrystone MIPS/MHz and supports low-power operation down to 268 nA in VLLS0 mode with full state retention-ideal for battery-powered industrial HMI and USB-connected sensor gateways.

For engineers reviewing the MK22FN1M0VLL12 datasheet, MK22FN1M0VLL12 pinout, MK22FN1M0VLL12 application, or MK22FN1M0VLL12 equivalent, key selection criteria include its 100-pin LQFP package, dual 16-bit SAR ADCs, CAN 2.0B interface, five UARTs, and verified support for USB device charger detection and FlexMemory configuration.

Technical Context

The MK22FN1M0VLL12 implements a tightly coupled ARM Cortex-M4 core with hardware floating-point unit and DSP extensions, operating at up to 120 MHz in PEE clock mode using an internal PLL fed by a 3–32 MHz crystal oscillator. Its memory subsystem includes 1 MB on-chip flash with error correction, 128 KB SRAM, and optional FlexNVM/FlexRAM partitions configurable via runtime commands.

Peripheral integration centers on deterministic real-time control: two 8-channel FlexTimer modules support PWM generation and motor control, while three SPI, three I²C, and five UART interfaces enable multi-protocol connectivity. The USB OTG controller operates in device/host/OTG modes with embedded voltage regulation, and the dual 16-bit ADCs feature hardware averaging and programmable conversion triggers.

FAQ

What is the maximum operating frequency of the MK22FN1M0VLL12 core?

The MK22FN1M0VLL12 features an ARM Cortex-M4 core with FPU rated for up to 120 MHz operation. This maximum frequency is achieved in PEE (Phase-Locked Loop Engaged) mode using the internal PLL with a 3–32 MHz crystal input. At 120 MHz, it delivers 1.25 Dhrystone MIPS per MHz, enabling efficient execution of floating-point-intensive algorithms without software emulation overhead. The MK22FN1M0VLL12 maintains this performance across its full –40°C to +105°C operating range when powered within 1.71–3.6 V.

Does the MK22FN1M0VLL12 support USB device charger detection?

Yes, the MK22FN1M0VLL12 integrates a dedicated USB Device Charger Detect (DCD) module compliant with USB Battery Charging Specification v1.2. This allows the MK22FN1M0VLL12 to automatically identify downstream port types (SDP, CDP, DCP) during enumeration and configure appropriate current limits-enabling fast charging support in USB-powered applications without external circuitry. The DCD function operates independently of the main USB OTG controller and is validated in the K22F datasheet Rev 4.

What low-power modes are available on the MK22FN1M0VLL12, and what is the lowest current draw?

The MK22FN1M0VLL12 supports seven low-power modes including VLLS0 (Very-Low-Leakage Stop 0), which achieves 268 nA typical current draw at 3.0 V with full RAM and register retention and 5 μs wakeup time. Other modes include VLPR (Very-Low-Power Run) at 1.21 mA, STOP at 0.528 μA, and VLLS3 at 3.1 μA-all measured at –40°C to +25°C. These modes are managed by the Low-Leakage Wakeup Unit (LLWU) and support flexible wake sources including GPIO, RTC, and analog comparators.

Can the MK22FN1M0VLL12 be used in automotive applications?

Yes, the MK22FN1M0VLL12 is qualified for automotive applications with an operating ambient temperature range of –40°C to +105°C and AEC-Q100 stress test compliance per Freescale/NXP documentation. Its integrated CAN 2.0B controller, robust ESD ratings (±2000 V HBM), and support for ISO 11898-2 physical layer signaling make it suitable for body control modules, diagnostic tools, and infotainment interfaces. The MK22FN1M0VLL12 also includes hardware CRC and memory protection for functional safety–relevant firmware integrity.

What is the purpose of FlexMemory in the MK22FN1M0VLL12?

FlexMemory in the MK22FN1M0VLL12 refers to a configurable memory block comprising up to 128 KB of FlexNVM (emulated EEPROM) and 4 KB of FlexRAM. Unlike standard flash, FlexNVM supports byte-level erase and write operations with 100k-cycle endurance-enabling reliable data logging, parameter storage, and wear-leveling without external EEPROM. FlexRAM acts as a fast, non-volatile backup buffer. Configuration is performed at runtime via the Flash API, and the MK22FN1M0VLL12's FlexMemory is electrically distinct from main program flash.
