Handling and ESD tips General handling of your TQ-products The TQ-product may only be used and serviced by certified personnel who have taken note of the information, the safety regulations in this document and all related rules and regulations. A general rule is: do not touch the TQ-product during operation. This is especially important when switching on, changing jumper settings or connecting other devices without ensuring beforehand that the power supply of the system has been switched off. -
Page 8: Naming Of Signals
The electronic components of your TQ-product are sensitive to electrostatic discharge (ESD). Always wear antistatic clothing, use ESD-safe tools, packing materials etc., and operate your TQ- product in an ESD-safe environment. Especially when you switch modules on, change jumper settings, or connect other devices. -
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 0103 l © 2025, 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. -

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). -

Page 23: 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 24: 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. -
