Key Features

• CPU Core Quad ARM® Cortex®-A53 cores at 1.6 GHz with a 1 MB L2 cache, delivering 64-bit processing for general-purpose and networking tasks.
• Memory Support Integrated DDR3L and DDR4 memory controllers to support modern system memory designs.
• Ethernet and Networking I/O Multiple Ethernet options including 1 GbE (4), 2.5 GbE (2) and 10 GbE (1) interfaces, plus integrated Frame Manager and packet offload capabilities to accelerate network processing.
• Storage and Peripheral I/O SATA 6 Gbps (1) and three USB 3.0 ports with PHY provide high-speed storage and peripheral connectivity; additional interfaces include I2C.
• PCIe and SerDes Multi-protocol SerDes and three PCIe® Gen2 DMA-controlled ports enable flexible high-speed peripheral attachment and board-level integration.
• Security and Acceleration ARM TrustZone (ARM TZ), boot security, and an integrated security engine (SEC 5.4) support secure boot and inline IPsec/offload for reduced CPU overhead.
• Data Path Acceleration QorIQ Data Path Acceleration Architecture (DPAA) and Frame Manager provide hardware packet parsing, classification and processing to help achieve greater than 10 Gb/s of system-level throughput as shown in datasheet guidance.
• Package and Reliability 780‑FBGA (23×23) surface-mount package and industrial qualification with an operating temperature range of -40 °C to 105 °C suitable for harsh environments.

Typical Applications

• Branch Office Routers: Compact routing platforms can use the LS1043A to combine multi-core packet processing with integrated Ethernet and PCIe connectivity for WAN/LAN aggregation.
• vCPE and Edge Equipment: Virtualized customer premises equipment and edge appliances benefit from 64-bit cores and hardware offloads for mixed network and compute workloads.
• Multi-protocol IoT Gateways: Use the processor’s diverse I/O, SerDes and QUICC Engine support for protocol bridging in IoT and M2M gateway designs.
• Industrial PLC and Control: Industrial control systems can leverage the industrial qualification, extended temperature range and deterministic networking features.
• Security Appliances: Integrated security engine and packet processing acceleration enable inline IPsec and other secure networking use cases.

Unique Advantages

• Integrated Networking Fabric: Frame Manager and DPAA offloads reduce CPU burden for packet processing, enabling higher aggregate throughput without adding external accelerators.
• Flexible I/O Mix: On-chip support for multiple Ethernet speeds, SATA, USB 3.0, PCIe and SerDes simplifies BOM and board-level design for compact systems.
• Security Built In: ARM TrustZone, boot security and the SEC engine provide hardware-assisted secure boot and inline cryptographic offload to protect data flows.
• Industrial Qualification and Temperature Range: -40 °C to 105 °C operation and industrial qualification support deployment in demanding embedded environments.
• Performance per Watt Focus: Four 64-bit Cortex-A53 cores and efficient interconnect/cache design target an effective balance of processing throughput and energy efficiency for edge applications.
