LS1043ASN8MNLB

The LS1043ASN8MNLB is an NXP QorIQ Layerscape microprocessor featuring a 4‑core, 64‑bit ARM® Cortex®‑A53 CPU complex running at 1.2 GHz. It is designed for embedded networking and industrial infrastructure applications where dense I/O and efficient packet processing are required.

Built for small‑form‑factor networking and edge devices, the LS1043A series combines multi‑protocol SerDes, hardware packet acceleration and a flexible set of high‑speed interfaces to deliver integrated performance and system design simplicity.

Key Features

• Core and CPU Quad ARM® Cortex®‑A53 cores, 64‑bit operation at 1.2 GHz with a large 1 MB L2 cache for efficient general‑purpose processing.
• Memory Supports DDR3L and DDR4 memory controllers to match system performance and cost targets.
• Ethernet and Networking Flexible Ethernet options: up to seven 1 GbE ports, or a combination of 1×10 GbE plus 5×1 GbE. Integrated Frame Manager provides hardware packet parsing, classification and policing with IEEE 1588 support.
• High‑speed SerDes and PCIe Four‑lane, multi‑protocol SerDes and three DMA‑controlled PCI Express Gen2 ports for high‑speed peripheral and accelerator connectivity.
• Storage and USB Single SATA 3.0 port (6 Gbps) and three USB 3.0 ports (with PHY) for modern storage and peripheral interfaces.
• Security Secure Boot and ARM TrustZone® support, plus integrated security engine (SEC 5.4) to enable in‑line IPsec and hardware‑accelerated cryptography.
• System Integration QorIQ Data Path Acceleration Architecture (DPAA) offload engines to enable multi‑Gb/s packet processing with lower CPU overhead; QUICC Engine technology for legacy protocol support.
• Package and Environmental Supplied in a 780‑FBGA (780‑FCPBGA 23×23) surface‑mount package. Operating temperature range 0 °C to 105 °C. RoHS compliant.

Typical Applications

• Branch Office Routers High‑density Ethernet and PCIe connectivity combined with packet acceleration make the device suitable for small router and firewall platforms.
• vCPE and Edge Equipment Quad‑core 64‑bit processing and DPAA offloads support virtualized CPE and edge network functions with reduced CPU load.
• Multi‑protocol IoT Gateways Flexible SerDes and legacy protocol support via QUICC Engine enable protocol bridging and gateway functions for industrial IoT.
• Industrial PLC and Control Deterministic packet handling, integrated security and extended temperature operation support industrial control and automation applications.
• Security Appliances Integrated SEC engine and hardware packet processing enable inline IPsec and accelerated cryptographic workloads for security devices.

Unique Advantages

• Highly integrated networking interfaces: Multiple GbE/10GbE options, SerDes lanes and PCIe ports reduce external PHY and bridge requirements.
• Packet acceleration with low CPU overhead: DPAA and Frame Manager offload parsing, classification and policing to free CPU cycles for application tasks.
• Built‑in security features: Secure Boot, TrustZone® and the SEC engine provide hardware foundations for secure systems and inline IPsec.
• Flexible memory and I/O choices: DDR3L/DDR4 support, SATA 3.0 and USB 3.0 enable a range of storage and peripheral configurations.
• System design optimization: Architecture and integrated peripherals support small‑form‑factor, fanless designs with simplified BOM and power supply requirements.
