Notes
1. ESD testing is performed in accordance with the Human Body Model (HBM) (AEC-Q100-2) (C ZAP = 100 pF, R ZAP = 1500 Ω ), and the
Machine Model (MM) (C ZAP = 200 pF, R ZAP = 0 Ω.

Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL), Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes
and enter the core ID to view all orderable parts. (i.e. MC33xxxD enter 33xxx), and review parametrics.
Per JEDEC51-8 Standard for Multilayer PCB
Theoretical thermal resistance is from the die junction to the exposed pad.
