Power consumption
The following table lists some technical parameters of the module supply. The specified current consumptions are to be
regarded as a guide value. Since the current consumption of the TQMaX4XxL can differ greatly depending on the application,
modes and operating system, the values listed here should only be used for a performance estimate.

TQMaX4XxL interface
The TQMaX4XxL has a total of 366 connections, designed as LGA balls, to ensure a high-quality connection when reflow
soldering the TQMaX4XxL. By using the LGA design, the module is soldered once and thus has a permanent connection to its
periphery. Removing the module from its soldered position is not possible without further ado, is not recommended and can
lead to a reduction in the service life or to its destruction.r LGA pads must be free of grease and contamination.

Pin assignment
The multiple pin configurations of all AM64x/AM243x internal function units must be taken note of.
The pin assignment shown in Table 31 refers to the corresponding
BSP provided by TQ-Systems GmbH
The electrical and pin characteristics are to be taken from the AM64x / AM243x (1) (2) (3).
