Operating ranges

Table 9 provides the operating ranges of the i.MX 7Dual family of processors. For details on the chip's

power structure, see the “Power Management Unit (PMU)” chapter of the i.MX 7Dual Application

Processor Reference Manual (IMX7DRM).

5 Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883 Method

1012.1).

6 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.
