1.5 Tips on safety

Improper or incorrect handling of the product can substantially reduce its life span.

1.6 Symbols and typographic conventions

Table 1: Terms and Conventions

Symbol Meaning

This symbol represents the handling of electrostatic-sensitive modules and / or components. These

components are often damaged / destroyed by the transmission of a voltage higher than about 50 V.

A human body usually only experiences electrostatic discharges above approximately 3,000 V.

This symbol indicates the possible use of voltages higher than 24 V.

Please note the relevant statutory regulations in this regard.

Non-compliance with these regulations can lead to serious damage to your health and also cause

damage / destruction of the component.

This symbol indicates a possible source of danger. Acting against the procedure described can lead to

possible damage to your health and / or cause damage / destruction of the material used.

This symbol represents important details or aspects for working with TQ-products.

Command

A font with fixed-width is used to denote commands, contents, file names, or menu items.

1.7 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.

Violation of this guideline may result in damage / destruction of the TQMLS1028A and be dangerous

to your health.

Improper handling of your TQ-product would render the guarantee invalid.

Proper ESD handling

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.

1.8 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.

Example: C / D#

If a signal has multiple functions, the individual functions are separated by slashes when they are important for the wiring.

The identification of the individual functions follows the above conventions.

Example: WE2# / OE#

1.9 Further applicable documents / presumed knowledge

•Specifications and manual of the modules used:

These documents describe the service, functionality and special characteristics of the module used (incl. BIOS).

•Specifications of the components used:

The manufacturer's specifications of the components used, for example CompactFlash cards, are to be taken note of.

They contain, if applicable, additional information that must be taken note of for safe and reliable operation.

These documents are stored at TQ-Systems GmbH.

•Chip errata:

It is the user's responsibility to make sure all errata published by the manufacturer of each component are taken note of.

The manufacturer’s advice should be followed.

•Software behaviour:

No warranty can be given, nor responsibility taken for any unexpected software behaviour due to deficient components.

•General expertise:

Expertise in electrical engineering / computer engineering is required for the installation and the use of the device.

The following documents are required to fully comprehend the following contents:

•MBLS1028A circuit diagram

•MBLS1028A User's Manual

•LS1028A Data Sheet

•U-Boot documentation: www.denx.de/wiki/U-Boot/Documentation

•Yocto documentation: www.yoctoproject.org/docs/

•TQ-Support Wiki: Support-Wiki TQMLS1028A

2. BRIEF DESCRIPTION

This User's Manual describes the hardware of the TQMLS1028A revision 02xx, and refers to some software settings.

Differences to TQMLS1028A revision 01xx are noted, when applicable.

A certain TQMLS1028A derivative does not necessarily provide all features described in this User's Manual.

This User's Manual does also not replace the NXP CPU Reference Manuals.

The information provided in this User's Manual is only valid in connection with the tailored boot loader,

which is preinstalled on the 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.

The TQMLS1028A extends the TQ-Systems GmbH product range and offers an outstanding computing performance.

A suitable CPU derivative (LS1028A / LS1018A / LS1027A / LS1017A) can be selected for each requirement.

All essential CPU pins are routed to the TQMLS1028A connectors.

There are therefore no restrictions for customers using the TQMLS1028A with respect to an integrated customised design.

Furthermore all components required for the correct CPU operation, like DDR4 SDRAM, eMMC, power supply and power

management are integrated on the TQMLS1028A. The main TQMLS1028A characteristics are:

•CPU derivatives LS1028A / LS1018A / LS1027A / LS1017A

•DDR4 SDRAM, ECC as an assembly option

•eMMC NAND Flash

•QSPI NOR Flash

•Single supply voltage 5 V

•RTC / EEPROM / temperature sensor

The MBLS1028A also serves as carrier board and reference platform for the TQMLS1028A.

3. OVERVIEW

3.1 Block diagram

Figure 1: Block diagram TQMLS1028A (simplified)

3.2 System components

The TQMLS1028A provides the following key functions and characteristics:

•Layerscape CPU LS1028A or pin compatible, see 4.1

•DDR4 SDRAM with ECC (ECC is an assembly option)

•QSPI NOR Flash (assembly option)

•eMMC NAND Flash

•Oscillators

•Reset structure, Supervisor and Power Management

•System Controller for Reset-Configuration and Power Management

•Voltage regulators for all voltages used on the TQMLS1028A

•Voltage supervision

•Temperature sensors

•Secure Element SE050 (assembly option)

•RTC

•EEPROM

•Boar-to-Board connectors

All essential CPU pins are routed to the TQMLS1028A connectors. There are therefore no restrictions for customers using the

TQMLS1028A with respect to an integrated customised design. The functionality of the different TQMLS1028A is mainly

determined by the features provided by the respective CPU derivative.
