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#

BRIEF DESCRIPTION
This User's Manual describes the hardware of the TQMLS10xxA, Rev. 02xx and refers to some software settings. A certain
TQMLS10xxA 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 TQMLS10xxA, and the BSP provided by TQ-Systems GmbH. See also chapter 6.
The TQMLS10xxA is a universal Minimodule based on the NXP Layerscape CPUs LS1043A / LS1046A / LS1088A. The Layerscape
CPU is a Dual Cortex
®
A7 with QorIQ technology. The TQMLS10xxA extends the TQ-Systems GmbH product range and offers an
outstanding computing performance. A suitable CPU derivative (LS1043A / LS1046A / LS1088A) can be selected for each
requirement. All essential CPU pins are routed to the TQMLS10xxA connectors. There are therefore no restrictions for customers
using the TQMLS10xxA with respect to an integrated customised design. Furthermore all components required for the CPU to
function like DDR4 SDRAM, eMMC, power supply and power management are integrated on the TQMLS10xxA.
The main TQMLS10xxA characteristics are:
•
CPU derivatives LS1043A (LS1023A), LS1046A (LS1026A), LS1088A
•
DDR4 SDRAM with ECC
•
eMMC and QSPI NOR flash
•
Single supply voltage 5 V
•
On-board RTC / EEPROM / temperature sensor
The MBLS10xxA also serves as carrier board and reference platform for the TQMLS10xxA.
