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 may damage
or destroy the component.
This symbol indicates a possible source of danger.
Ignoring the instructions described can cause health damage, or damage the hardware.
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 not to 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 TQMa93xxLA 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.

User's Manual l TQMa93xxLA UM 0005 l © 2023, TQ-Systems GmbH Page 3
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#

2. BRIEF DESCRIPTION
This User's Manual describes the hardware of the TQMa93xxLA as of revision 0100, in combination with the MBa93xxLA as of
revision 0100 and refers to some software settings. A certain TQMa93xxLA derivative does not necessarily provide all features
described in this User's Manual.
This User's Manual does neither replace the i.MX 93 Reference Manual (1), nor the i.MX 93 Data Sheet (2), nor any other
documents from NXP.
The TQMa93xxLA is a universal Minimodule based on the NXP ARM®Cortex®-A55 based i.MX 93 CPU family, see also Table 4.
2.1 Key functions and characteristics
The TQMa93xxLA extends the TQ-Systems GmbH product range and offers an outstanding computing performance.
All essential i.MX 93 signals are routed to the TQMa93xxLA LGA pads. There are therefore no restrictions for customers using the
TQMa93xxLA with respect to an integrated customised design. All essential components like CPU, LPDDR4, eMMC, and PMIC are
already integrated on the TQMa93xxLA.
The main features of the TQMa93xxLA are:
•64 bit NXP i.MX 93 CPU, up to 2 × ARM Cortex®-A55 and 1 × Cortex®-M33
•Up to 2 Gbyte of LPDDR4- or LPDDR4X RAM
•Up to 256 Gbyte of eMMC NAND Flash, eMMC standard 5.1
•Up to 256 Mbyte QSPI NOR Flash (optional)
•64 Kbit EEPROM (optional)
•Temperature sensor + EEPROM
•NXP Power Management Integrated Circuit PCA9451
•RTC (optional)
•Trust Secure Element (optional)
•Gyroscope (optional)
•All essential i.MX 93 signals are routed to the TQMa93xxLA LGA pads
•Single supply voltage 5 V

3.1 Interfaces to other systems and devices
3.1.1 Pin multiplexing
The multiple pin configurations by different i.MX 93 internal function units must be taken note of.
The pin assignment in Table 3 refers to a TQMa93xxLA with i.MX 93 CPU in combination with the carrier board MBa93xxLA.
NXP provides a tool showing the multiplexing and simplifies the selection and configuration (i.MX Pins Tool NXP Tool).
The electrical and pin characteristics are to be taken from the i.MX 93 and PMIC documentation, see Table 37.
Attention: Destruction or malfunction, pin multiplexing
Depending on the configuration, many i.MX 93 pins can provide several different functions.
Please take note of the information concerning the configuration of these pins in the i.MX 93
Reference Manual (1), before integration or start-up of your carrier board / Starterkit.
Improper programming by operating software can cause malfunctions, deterioration or
destruction of the TQMa93xxLA.
The descriptions given in the following tables should be taken note of:
−DNC: These pins must never be connected and have to be left open.
Please contact TQ-Support for details.

Attention: Destruction or malfunction, i.MX 93 errata
Please take note of the current i.MX 93 errata (5).
3.2.1.3 Boot modes
The i.MX 93 has a ROM with integrated boot loader. After the release of PMIC_POR# the System Controller (SCU) boots from
the internal ROM and then loads the program image from the selected boot device. For example, the integrated eMMC or the
optional QSPI NOR Flash can be selected as the default boot device. The following boot sources are supported by TQMa93xxLA:
•eMMC (SD1)
•QSPI/FlexSPI NOR Flash (SD1 + SD3)
•SD card (SD2)
•Serial Download (USB1)
Alternatively, an image can be loaded into the internal RAM using the serial downloader.
More information about the boot flow can be found in the Reference Manual (1), and the Data Sheet (2) of i.MX 93.

3.2.1.4 Boot configuration
This section provides information on boot mode configuration pads allocation and boot device interface allocation. The i.MX 93
uses four BOOT_MODE signals provided on the TQMa93xxLA's LGA pads. These require pull-up/pull-down (4.7 / 100 )
wiring to 3.3 V and Ground. However, the BOOT_MODE signals are not dedicated to this function, but have other functionalities
in normal operation. The boot mode is initialized by sampling the BOOT_MODE[3:0] inputs when the reset is deactivated and are
to be set high or low according to the desired boot source at the time of readout. After these inputs are sampled, their
subsequent state does not affect the contents of the BOOT_MODE internal register.
The exact boot source configuration can be seen in the following table.

BOOT_MODE3 is used to distinguish between Low Power Boot (LPB - start of the M33 core) and Single Boot (start of the A55
core).
In LPB, only the M33 ROM is running after Power-On Reset (POR); the A55 core is expected to be kicked off by M33 firmware in
some use cases.
In Single Boot, the Cortex-A55 ROM loads both the Cortex-A55 firmware image and the Cortex-M33 firmware image (if exists). If
the container set has the Cortex-M33 firmware image, the Cortex-A55 ROM will read and place it in the Shared RAM (Cortex-M33
TCM). The Cortex-M33 BootROM is not involved in the Single Boot Flow. Once the Cortex-A55 loads the Cortex-M33 firmware
image to the Cortex-M33 TCM, the Cortex-A55 ROM will issue a message that kick off the Cortex-M33 core, and continues the
Cortex-A55 boot process, with Cortex-M33 & Cortex-A55 boot running in parallel.

3.2.2 Memory
3.2.2.1 LPDDR4 SDRAM
The memory interface of the i.MX 93 supports LPDDR4 and LPDDR4X memory (16 bit bus) with a maximum clock rate of 1866
MHz, which meets JEDEC LPDDR4-3733 standard. 1 GByte is the standard configuration, a maximum of 2 Gbyte of LPDDR4
SDRAM is supported.
3.2.2.2 eMMC
An eMMC is provided on the TQMa93xxLA for boot loader, operating system and application software. It is connected to the
i.MX 93 via SD1-interface. A maximum transfer rate of 400 MB/s is supported (HS400 mode). Resets have to be done via software.

3.2.2.3 QSPI NOR Flash / NAND Flash
QSPI NOR flash can optionally be assembled on the TQMa93xxLA. Because a separation of the signal paths is not possible, these
LGA pads must not be wired when equipped with NOR Flash. With unpopulated NOR Flash the signals of the SD3 interface can
be used outside the module.
The NOR flash signals use a part of the NAND pins of the i.MX 93. All other NAND pins of the i.MX 93 are used from the
TQMa93xxLA for the eMMC as SD1 boot source and for the SD-Card (SD2).
