LS1043AXE8KQB

The LS1043AXE8KQB is an NXP QorIQ Layerscape communications microprocessor featuring a quad-core ARM® Cortex®-A53 64‑bit CPU running at 1.6 GHz in a 780‑FCPBGA (23×23) package. It is designed for embedded networking and industrial infrastructure use.

Targeted at enterprise edge, industrial and networking applications, the device combines multi-core 64‑bit processing, integrated I/O and acceleration engines to deliver high throughput (up to 10 Gb/s data plane performance as described in product documentation) with hardware-assisted packet processing and security.

Key Features

• CPU Core  Quad ARM® Cortex®-A53 64‑bit cores at 1.6 GHz with a 1 MB L2 cache, offering efficient general‑purpose processing for embedded networking workloads.
• Memory  Integrated DDR3L and DDR4 memory controllers for flexible system memory options.
• Networking & Packet Processing  Frame Manager with hardware packet parsing, classification and policing; support for up to six Gigabit Ethernet ports with IEEE® 1588 timestamping as documented for the series.
• High‑Speed SerDes & Interfaces  Four‑lane, 10 GHz multi‑protocol SerDes; up to three PCIe® Gen2 DMA‑controlled ports; single SATA 3.0 (6 Gbps) port; and three USB 3.0 ports plus PHY.
• Security & Offload Engines  Secure Boot and ARM® TrustZone® are listed as security features; integrated security engine (SEC 5.4) and Frame Manager support in‑line IPsec and DPAA (Data Path Acceleration Architecture) offloads to reduce CPU overhead for packet processing.
• Legacy Protocol Support  Integrated QUICC Engine technology for glue‑less support of legacy protocols such as HDLC, TDM and PROFIBUS (described in series documentation).
• Package & Environmental  780‑FCPBGA (23×23) surface‑mount package; industrial qualification and operating temperature range of −40 °C to +105 °C. RoHS compliant.

Typical Applications

• Integrated Services & Edge Appliances  Use as the communications processor in compact service appliances that require multi‑port Ethernet, hardware packet parsing and security offload.
• Branch Office Routers and vCPE  Platform for branch routers and virtual CPE devices where multi‑core general processing and DPAA offload support throughput up to the tens of Gb/s range as described.
• Multi‑protocol IoT Gateways  Gateway designs that need flexible I/O, SerDes connectivity and legacy protocol support for industrial field interfaces.
• Industrial PLC and Control  Industrial control systems benefiting from industrial temperature qualification, integrated networking and security features.
• Security Appliances  Network security appliances leveraging the integrated security engine and Frame Manager for in‑line IPsec and packet processing.

Unique Advantages

• Highly integrated networking I/O: Multiple Gigabit Ethernet ports, PCIe, USB3, SATA and a multi‑protocol SerDes reduce the need for external controllers and simplify board-level I/O design.
• Packet and security offload: DPAA and the integrated SEC 5.4 security engine plus Frame Manager enable hardware acceleration of packet handling and IPsec to lower CPU overhead.
• 64‑bit multi‑core performance at 1.6 GHz: Quad Cortex‑A53 cores with a 1 MB L2 cache provide a balance of compute capability and energy efficiency for edge and embedded networking workloads.
• Legacy protocol support: QUICC Engine technology permits glue‑less integration of HDLC, TDM and PROFIBUS where needed in industrial and telecom applications.
• Industrial readiness: Industrial qualification and a −40 °C to +105 °C operating range support deployment in temperature‑demanding embedded environments.
