Block diagram TQMa53
The main components of the processor module TQMa53 are the i.MX53-CPU, DDR3 SDRAM and eMMC memory.
The technical characteristics of the TQMa53 are to be taken from the User's a Manual
1
.
The available signals are routed over the two 120-pin module connectors X1 and X2 to the STK-MBa53.
Table 7 and Table 8 show the pins assignment of the connectors as well as signal names and directions seen from the TQMa53.
The boot-mode configuration of the i.MX53 is set via DIP switches. See section 4.3.5, Boot-Mode configuration.
The TQMa53 can be plugged put on mating connectors of different stack height on the carrier board.
In this way different board to board distances can be achieved, which are shown in Table 5.
