Frequently asked questions
Is the MK22FN512CAP12R the only package option for this part number?
No — the same die (512KB Flash, 120MHz Cortex-M4, Kinetis K20 base product number) is also available in LQFP-64 as the MK22FN512VLH12. The two packages have different pinouts; the WLCSP and LQFP variants are not footprint-compatible and a board respin would be required to switch between them.
Can the 80-WLCSP be hand-soldered or rework in the field?
No. The 80-ball WLCSP (4.13×3.56mm) requires reflow assembly and BGA rework equipment. If your production process cannot handle micro-BGA placement and rework, specify the LQFP-64 variant instead — that is the practical hand-solder option for this die.
Is the MK22FN512CAP12R 5 V-tolerant on its GPIO pins?
No. The GPIO operating voltage tracks the 1.71–3.6V supply range — the part is designed for 3.3 V nominal rails. Interfacing to 5 V logic or 24 V industrial sensors requires external level-shifting circuitry; budget those components and board area into your design.
