Product details

The NXP MK22FN512VDC12R is a Kinetis K20 series ARM Cortex-M4 MCU clocked at 120 MHz, with 512 KB of Flash and 128 KB of RAM on a 32-bit single-core fabric. It carries a 16-bit ADC with 38 channels and a 12-bit DAC with 2 channels.

Memory and peripheral budget

512 KB of Flash is sized for a firmware image that includes a real-time OS, a USB stack, and moderate application logic; 128 KB RAM supports packet buffering and data acquisition without external SRAM. The 81 I/O count is high relative to the 121-ball BGA footprint, which means several pins share multiplexed functions — verify pin allocation against the required peripherals before layout.

Frequently asked questions

What are the exact specifications of MK22FN512VDC12R?

The MK22FN512VDC12R is an NXP Kinetis K20 ARM Cortex-M4 MCU running at 120 MHz, with 512 KB Flash, 128 KB RAM, 81 I/O, USB OTG, a 38-channel 16-bit ADC, a 2-channel 12-bit DAC, operating from 1.71 to 3.6 V over -40 to 105 °C in a 121-XFBGA package.
