MKL25Z128VLK4 Pinout

Package: QFN 32-pin

Notes

CRITICAL: The provided datasheet section contains only 4 pins of the 32-pin QFN package. The table is incomplete and does not show pins 5–32.

Pin numbering: Pin numbers (1–4) are taken directly from the "32 QFN" column in the source table.

Missing pins: Pins 5–32 are not included in the extracted section. A complete pinout table for the MKL25Z128VLK4 requires the full datasheet section covering all 32 pins. The user should consult the complete datasheet or provide the full pin assignment table.

Unless otherwise specified, propagation delays are measured from the 50% to the 50% point, and rise and fall times are measured at the 20% and 80% points, as shown in the following figure.

All digital I/O switching characteristics, unless otherwise specified, assume the output pins have the following characteristics.

• CL=30 pF loads
• Slew rate disabled
• Normal drive strength
