System components
The TQMLS10xxA provides the following key functions and characteristics:
•
Layerscape CPUs LS1043A (LS1023A), LS1046A (LS1026A), LS1088A
•
Oscillators
•
Reset structure
•
Power supply and power-sequencing
•
Voltage supervision
•
Housekeeping µController
•
Temperature sensor
•
RTC
•
EEPROM
•
DDR4 SDRAM with ECC
•
QSPI NOR flash
•
eMMC
•
Four connectors (420 pins)
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.
All TQMLS10xxA versions are fully pin-compatible and therefore interchangeable. The functionality of the different TQMLS10xxA
is mainly determined by the features provided by the respective CPU.
