System components

The TQMLS1028A provides the following key functions and characteristics:
• Layerscape CPUs LS1028A / LS1018A / LS1027A / LS1017A
• Oscillators
• Reset structure, Supervisor and Power Management
• System Controller for Reset-configuration and Power Management
• Power supply, and Power-Sequencing
• Voltage supervision
• Temperature sensors
• RTC
• EEPROM
• DDR4 SDRAM with ECC
• QSPI NOR Flash
• eMMC NAND Flash
• Two connectors (240 pins)
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. All TQMLS1028A versions are fully pin-compatible and therefore
interchangeable. The functionality of the different TQMLS1028A is mainly determined by the features provided by the respective
CPU derivative.
