Product details

The MK22FN512VLL12R is an NXP Kinetis K20 series 32-bit ARM Cortex-M4 MCU running at 120 MHz, with 512 KB Flash and 128 KB RAM.

On-chip peripherals include DMA, I²S, LVD, POR, PWM, and WDT. Connectivity covers I²C, IrDA, SPI, UART/USART, USB with OTG support. The USB OTG enables dual-role host/device operation — useful for field-update dongles or direct connection to a tablet. The 33-channel 16-bit ADC and dual 12-bit DAC handle analog sensor inputs and control outputs without external converters.

Frequently asked questions

What is the closest pin-compatible alternative to MK22FN512VLL12R in this family?

Within the Kinetis K20 family, the MK22FN256VLL12 (256 KB Flash) and MK22FN1M0VLL12 (1 MB Flash) are pin-compatible in the same 100-LQFP package. The difference is Flash density only — core, RAM, and peripherals are identical.

What is MK22FN512VLL12R's listed speed?

The core runs at 120 MHz, based on the ARM Cortex-M4 with FPU. That speed is the maximum operating frequency across the full -40°C to 105°C range.

What compliance documentation does NXP provide for MK22FN512VLL12R?

NXP provides RoHS and REACH compliance declarations for this part. The 100-LQFP package is lead-free and halogen-free per NXP's standard material declarations. UL and IEC certifications are not listed for this component; those apply at the system level, not the IC.
