TQMLS1028A pinout
All available TQMLS1028A signals are routed to two connectors on the MBLS1028A.
More detailed information is to be taken from the TQMLS1028A User’s Manual (4).
Note: Available interfaces
Depending on the TQMLS1028A derivative not all interfaces are available. Refer to the TQMLS1028A
User’s Manual and the TQMLS1028A pinout table to see which interfaces are available.
4.1.1.2
TQMLS1028A connectors
The MBLS1028A is connected to the carrier board with 240 pins on two connectors.
The following table shows details of the connectors assembled on the MBLS1028A:

The TQMLS1028A is held in the mating connectors on the TQMLS1028A by 240 pins with a retention force of approximately 24 N.
To avoid damaging the connectors of the MBLS1028A or the TQMLS1028A while removing the TQMLS1028A, the use of the
extraction tool MOZI8XX is strongly recommended.
4.1.1.3
Boot configuration
The boot mode of the TQMLS1028A is determined by the level of the analogue 3.3 V signal RCW_SRC_SEL.
The boot mode defines the boot device and specific configurations. The boot mode is set with DIP switches.
The following table shows the permitted Boot Mode settings:
