Frequently asked questions
Is the MKL15Z32VFM4 a direct drop-in for the MKL15Z64VFM4?
Pinout and package are shared (both are 32-HVQFN, 28 I/O), but the RAM delta — 4KB versus 8KB — means the 64VFM4's firmware may allocate runtime buffers that exceed the 32VFM4's RAM ceiling; a firmware patch or memory-map review is required before treating it as a substitute on a running board.
Is there a RoHS-compliant alternative in the KL15 series?
Yes — the KL15 series ships in both leaded and RoHS-compliant variants; confirm the exact order code suffix with your distributor, as the RoHS variant of the 32-HVQFN MKL15 may carry a different MPN suffix. The MKL15Z32VFM4 itself is listed non-RoHS.
What does the wettable flank mean for rework on a production board?
The wettable flank is a visual and mechanical solder-joint integrity feature for the 32-HVQFN exposed pad — it allows automated optical inspection of the joint and confirms solder coverage on the thermal pad after reflow; it does not specify a maximum reprocess cycle count, so validate rework thermal exposure against your board assembly profile.
What supply rail does the board need?
1.71V to 3.6V single supply — a 3.3V rail is the nominal operating point, and the internal oscillator removes the need for an external crystal at 48MHz.
