Two cores at 1.2 GHz for the control plane
The NXP LS1021AXN7MQB is a QorIQ Layerscale dual-core ARM Cortex-A7 processor running at 1.2 GHz. It targets the control-plane role in industrial switches, programmable logic controllers, and network-attached gateways. On the I/O side you get one USB 3.0 port with integrated PHY, one SATA 6 Gbps channel, and three Gigabit Ethernet MACs. That combination lets a single board serve as a storage appliance, a multi-port router, or a fieldbus head-end without external USB or SATA transceivers. The DDR3L/DDR4 memory controller gives the BOM flexibility to use whichever DRAM generation is cheaper at build time.
Temperature grade and enclosure fit
The 525-FCPBGA (19x19 mm) footprint is a standard BGA for this performance tier; plan for a multi-layer PCB with at least four signal layers to route the DDR and GbE traces cleanly.
NXP lists the LS1021AXN7MQB as Active and ROHS3 compliant.
