概述

Description

MK22FN512VFX12 is an NXP/Freescale Kinetis K22 family MCU built around a 32‑bit ARM Cortex‑M4 core. It runs up to 120 MHz and integrates 512 KB of flash and 128 KB of RAM. Peripherals typically include USB OTG FS, multiple UARTs/SPI/I2C, CAN (variant dependent), 12‑bit ADCs, a DAC, PWM/timers, RTC, and DMA with a memory protection unit. It supports low‑power modes and operates from a 1.71–3.6 V supply. Debugging is via SWD/JTAG, and development is supported by MCUXpresso and other toolchains. Common applications: motor control, USB devices, and mid‑range embedded systems requiring a versatile Cortex‑M4 MCU.

Features

Key features of MK22FN512VFX12:
