Page 12: Self-Reset
The output HRESET_REQ# is driven internally by the CPU and can be set by software in register RSTCR (bit 30). RESET_REQ# is returned to RESIN# within the TQMLS1028A (default). No additional feedback is necessary on the carrier board. When RESET_REQ# is triggered a self-reset is executed. -

4.12.2 Power consumption TQMLS1028A The given current consumptions have to be seen as typical values. The power consumption of the TQMLS1028A strongly depends on the application, the mode of operation and the operating system. The following table shows details of the TQMLS1028A supply and power consumption. -
Page 19: Interfaces To Other Systems And Devices
C buses of the LS1028A CPU (I2C1 to I2C6) are not terminated and routed to the TQMLS1028A connectors. The I2C1 bus is level shifted to 3.3 V and terminated with 4.7 kΩ pull-ups to 3.3 V on the TQMLS1028A. The I C devices on the TQMLS1028A are connected to the level-shifted I2C1 bus. -

Page 25: Connectors
The TQMLS1028A is held in the mating connectors with a retention force of approximately 24 N. To avoid damaging the TQMLS1028A connectors as well as the carrier board connectors while removing the TQMLS1028A the use of the extraction tool MOZI8XX is strongly recommended. See chapter 5.9 for further information. -
Page 26: Adaptation To The Environment
TQMLS1028A and thus malfunction, deterioration or destruction. Structural requirements The TQMLS1028A is held in the mating connectors by the retention force of the pins (240). If high requirements are set for vibration and shock resistance, additional fastening may be necessary. -
Page 27: Safety Requirements And Protective Regulations
Filtering of all signals, which can be connected externally (also "slow signals" and DC can radiate RF indirectly). Since the TQMLS1028A is plugged on an application-specific carrier board, EMC or ESD tests only make sense for the whole device. In order to avoid interspersion on the signal path from the input to the protection circuit in the system, the protection against electrostatic discharge should be arranged directly at the inputs of a system. -
Page 28: Environment Protection
By environmentally friendly processes, production equipment and products, we contribute to the protection of our environment. To be able to reuse the TQMLS1028A, it is produced in such a way (a modular construction) that it can be easily repaired and disassembled. The energy consumption of this subassembly is minimised by suitable measures. The TQMLS1028A is delivered in reusable packaging. -
