Notes
5.
Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause a malfunction or permanent damage to the device.
6.
Freescale's Package Reflow capability meets the Pb-free requirements for JEDEC standard J-STD-020C, for Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL).
7.
Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site (board) temperature, ambient
temperature, air flow, power dissipation of other components on the board, and board thermal resistance.
8.
Per JEDEC JESD51-2 with the single layer board horizontal. Board meets JESD51-9 specification.
9.
Per JEDEC JESD51-6 with the board horizontal.
10.
Thermal resistance between the die and the printed circuit board per JEDEC JESD51-8. Board temperature is measured on the top
surface of the board near the package.
11.
Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883 Method 1012.1).
12.
Thermal characterization parameter indicating the temperature difference between package top and the junction temperature per
JEDEC JESD51-2. When Greek letters are not available, the thermal characterization parameter is written as Psi-JT.
Table 5. Thermal Ratings (continued)
All voltages are with respect to ground unless otherwise noted. Exceeding these ratings may cause a malfunction or permanent
damage to the device.
