LS1043AXE7KQA

The LS1043AXE7KQA is an NXP QorIQ Layerscape microprocessor IC featuring a quad-core ARM® Cortex®-A53 64-bit CPU running at 1.0 GHz in a 621-FCPBGA (21×21) package. It is engineered for embedded networking and industrial infrastructure where multicore processing, flexible I/O and hardware security are required.

Targeted for edge and communications applications such as branch routers, vCPE, multi‑protocol IoT gateways and industrial control, the device combines multicore CPU performance, integrated networking and offload engines to deliver scalable throughput and BOM-optimized system designs suitable for fanless deployments.

Key Features

• CPU Core & Architecture Quad ARM® Cortex®-A53 64‑bit cores at 1 GHz with a series-level large 1 MB L2 cache for balanced performance and efficiency.
• Memory Integrated memory controller support for DDR3L and DDR4 devices to accommodate a range of system memory budgets.
• High‑Speed Networking & I/O Flexible Ethernet configurations (1 GbE up to seven ports, or 10 GbE plus additional 1 GbE ports), a SATA 6 Gbps port and three USB 3.0 ports with PHY support for diverse connectivity needs.
• PCIe & SerDes Multi‑lane SerDes and three DMA‑controlled PCI Express Gen2 ports provide high-speed peripheral and expansion interfaces.
• Data Path & Offload Engines Series-level Data Path Acceleration Architecture (DPAA) and Frame Manager support hardware packet parsing, classification and policing to reduce CPU overhead and enable multi‑Gb/s packet processing.
• Security Secure Boot and ARM TrustZone® support plus an integrated security engine (SEC) for in-line IPsec and cryptographic offload.
• System Integration & BOM Optimization Designed for low-layer PCBs, simplified power supply and single-clock designs to reduce system BOM and support fanless system implementations.
• Package & Industrial Temperature 621‑FCPBGA (21×21) surface-mount package with industrial qualification and an operating temperature range of −40 °C to 105 °C.

Typical Applications

• Branch Office Routers Multi‑core processing and integrated networking enable secure routing, QoS and packet processing in small‑form‑factor router platforms.
• vCPE and Edge Equipment Flexible I/O and offload engines help meet throughput requirements for virtualized customer premises equipment and edge appliances.
• Multi‑protocol IoT Gateways A combination of Ethernet, USB and serial expansion supports protocol bridging and gateway functions for distributed IoT deployments.
• Industrial PLC and Control Industrial temperature qualification and integrated interfaces support control and communications tasks in automation environments.
• Security Appliances Hardware security and packet-offload capabilities enable encrypted tunnels and secure traffic handling with reduced CPU load.

Unique Advantages

• Highly integrated platform: Combines multicore CPU, memory controllers and diverse high‑speed interfaces to reduce board complexity and component count.
• Flexible networking topology: Multiple Ethernet configurations plus SerDes and PCIe allow designers to tailor network and expansion options to application requirements.
• Hardware offload and packet processing: Data Path Acceleration Architecture and Frame Manager perform parsing and classification in hardware, lowering CPU overhead for multi‑Gb/s workloads.
