Page 8: Tips On Safety
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. -
Page 9: Naming Of Signals
Preliminary User's Manual l TQMa93xxLA UM 0003 l © 2023, 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 10: Brief Description
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. -

Page 19: Boot Configuration
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. -
