Interfaces not being utilized at a system level may require external pull-up or pull-down resistors. For specific details and
requirements, see Section 4.2, “Functional Signal Definitions” on page 43.
Pin Configuration is set by the Expansion bus configuration when Reset is deasserted.
Blank field indicates no physical ball on package.

Package Thermal Specifications
The thermal parameters defined in Table 27, Table 28, and Table 29 are based on
simulated results of packages assembled on standard multi-layer, 2s2p, 1.0-oz copper
layer boards in a natural convection environment. The maximum case temperature is
based on the maximum junction temperature and defined by the relationship:
T_case max = T_jmax - (Ψ_JT x Power)
Where Ψ_JT is the junction-to-package top thermal characterization parameter. If the
case temperature exceeds the specified T_case max, thermal enhancements such as heat
sinks or forced air will be required. In the tables below, Θ_JA is the package junction-to-
air thermal resistance.
