Page 8: Naming Of Signals
User's Manual l TQMLS1028A UM 0101 l © 2020, TQ-Systems GmbH Page 3 Naming of signals A hash mark (#) at the end of the signal name indicates a low-active signal. Example: RESET# If a signal can switch between two functions and if this is noted in the name of the signal, the low-active function is marked with a hash mark and shown at the end. -
Page 9: Brief Description
TQMLS1028A, and the BSP provided by TQ-Systems GmbH. See also chapter 6. The TQMLS1028A is a universal Minimodule based on the NXP Layerscape CPUs LS1028A / LS1018A / LS1027A / LS1017A. ®- These Layerscape CPUs feature a Single, or a Dual Cortex A72 core, with QorIQ technology. -

Page 14: Jtag-Reset Trst
The output HRESET_REQ# is driven internally by the CPU and can be set by software by writing to RSTCR register (bit 30). By default, RESET_REQ# is fed back via 10 kΩ to RESIN# on the TQMLS1028A. No feedback on the carrier board is required. - Page 15 User's Manual l TQMLS1028A UM 0101 l © 2020, TQ-Systems GmbH Page 10 4.2.3 Self-Reset on TQMLS1028A revision 02xx (continued) The following wirings show different possibilities to connect RESIN#.

Page 16: Ls1028A Configuration
The RCW source of the TQMLS1028A is determined by the level of the analogue 3.3 V signal RCW_SRC_SEL. The RCW source selection is managed by the system controller. A 10 kΩ Pull-Up to 3.3 V is assembled on the TQMLS1028A. -
Page 17: Reset Configuration Word
This state can only be exited with a PORESET_B or Hard Reset. System Controller The TQMLS1028A uses a system controller for housekeeping and initialization functions. This system controller also performs power sequencing and voltage monitoring. The functions are in detail: •... -
Page 18: System Clock
System Clock The system clock is permanently set to 100 MHz. Spread spectrum clocking is not possible. SDRAM 1, 2, 4 or 8 GB of DDR4-1600 SDRAM can be assembled on the TQMLS1028A. Flash Assembled on TQMLS1028A: • QSPI NOR Flash •... -
Page 19: Emmc / Sd Card
The LS1028A provides two SDHCs; one is for SD cards (with switchable I/O voltage) and the other is for the internal eMMC (fixed I/O voltage). When populated, the TQMLS1028A internal eMMC is connected to SDHC2. The maximum transfer rate corresponds to the HS400 mode (eMMC from 5.0). -

The accuracy of the RTC is primarily determined by the characteristics of the quartz used. The type FC-135 used on the TQMLS1028A has a standard frequency tolerance of ±20 ppm at +25 °C. (Parabolic coefficient: max. –0.04 × 10 –6 / °C... -
Page 22: Power Consumption Tqmls1028A
4.12 Power consumption TQMLS1028A The power consumption of the TQMLS1028A strongly depends on the application, the mode of operation and the operating system. For this reason the given values have to be seen as approximate values. Current peaks of 3.5 A may occur. The carrier board power supply should be designed for a TDP of 13.5 W. -
Page 23: I 2 C Bus
C buses of the LS1028A (I2C1 to I2C6) are routed to the TQMLS1028A connectors and not terminated. 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 29: 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 5.8 for further information. -
Page 30: Thermal Management
Both can be purchased separately for larger quantities. Please contact your local sales representative. Structural requirements The TQMLS1028A is held in its mating connectors by the 240 pins with a retention force of approximately 24 N. Notes of treatment To avoid damage caused by mechanical stress, the TQMLS1028A may only be extracted from the carrier board by using the extraction tool MOZI8XX that can also be obtained separately. -
Page 31: 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. -
Page 32: 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 the TQMLS1028A is minimised by suitable measures. The TQMLS1028A is delivered in reusable packaging. -
