Operating ranges

Table 10 provides the operating ranges of the i.MX RT1050 processors. For details on the chip's power

structure, see the “Power Management Unit (PMU)” chapter of the i.MX RT1050 Reference Manual

(IMXRT1050RM).

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.

7 Thermal resistance between the die and the central solder balls on the bottom of the package based on simulation.
