LS1043AXN7QQB

LS1043AXN7QQB is an NXP QorIQ LS1043A system-on-chip (SoC) used in embedded networking and edge devices. It packages four ARM Cortex-A53 cores and a suite of high‑speed I/O for routers, switches, VPN gateways, and industrial gateways. The XN7QQB suffix denotes a specific package/revision and temperature rating; exact meaning is in NXP’s datasheet.
Key points:
- Quad-core ARM Cortex-A53, typically for mid‑range to high‑performance edge workloads
- Rich interfaces for networking and storage (PCIe, USB, SATA, Ethernet MACs)
- Hardware cryptographic accelerators and virtualization support
- Linux and real-time OS compatibility; suitable for network processing and security workloads
For precise specifications (clock speed, I/O counts, memory interfaces, and package details), consult the LS1043A datasheet and ordering guide.
