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.
Per SEMI G38-87 and EIA/JESD51-2 with the single layer (1s) board horizontal.
Per JESD51-6 with the board horizontal.
Thermal resistance between the die and the printed circuit board per JESD 51-8. Board temperature is measured on the top surface of
the board near the package.
Values listed are based on simulations. Final values will be released when testing is complete.

Table 2-2 lists recommended operating conditions. Proper device operation outside of these conditions is
not guaranteed.
Table 2-3 describes thermal characteristics of the MSC8102 for the FC-CBGA (HCTE) package.
Note:
Section 4.1, Thermal Design Considerations provides a more detailed explanation of these
characteristics.
