Product details
Overview
MK22FX512VMC12 from NXP Semiconductors (formerly Freescale) is a 120 MHz ARM Cortex-M4F microcontroller with FPU, 512 KB flash, 128 KB SRAM, and integrated USB LS/FS OTG 2.0 controller with embedded 3.3 V/120 mA LDO regulator. It delivers 1.25 DMIPS/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 MK22FX512VMC12 datasheet, MK22FX512VMC12 pinout, MK22FX512VMC12 application, or MK22FX512VMC12 equivalent, key selection criteria include its 121-pin MAPBGA package, dual 16-bit SAR ADCs, CAN 2.0B interface, six UARTs, and verified support for Kinetis SDK v2.x and MCUXpresso IDE-enabling rapid development of deterministic real-time control systems with USB device/host capability.
Technical Context
The MK22FX512VMC12 implements a tightly coupled ARM Cortex-M4F core with hardware floating-point unit and DSP extensions, operating at up to 120 MHz in PEE clock mode using the MCG PLL. Its memory subsystem includes 512 KB on-chip flash with error correction, 128 KB SRAM, and optional FlexMemory (not enabled in this variant), supporting execute-in-place and secure boot via flash protection.
System-level integration includes a 16-channel DMA controller, memory protection unit (MPU) with multi-master arbitration, low-leakage wakeup unit (LLWU), and comprehensive clock tree with FLL, PLL, and multiple internal oscillators-including 32 kHz RTC oscillator and 1–32 MHz crystal support. Peripheral interconnect uses crossbar switch architecture for deterministic latency across USB, CAN, SPI, I²C, SDHC, and I²S modules.
