LS1043AXE7KQB

The LS1043AXE7KQB is a QorIQ Layerscape communications microprocessor featuring a quad-core ARM® Cortex®-A53 64‑bit CPU at 1.0 GHz. It targets embedded networking and industrial infrastructure designs with integrated I/O, memory controllers, and security features tailored for edge, gateway and control applications.

Designed for compact, fanless and industrial systems, the device combines multi-port Ethernet capability, PCIe, USB 3.0 and SATA, along with TrustZone® and Secure Boot support to deliver a balanced platform for networking, IoT gateway, and industrial control use cases.

Key Features

• CPU Core  Quad ARM® Cortex®-A53 64‑bit processors running at 1 GHz with a shared L2 cache for multi-threaded embedded workloads.
• Memory and Storage  Integrated memory controllers supporting DDR3L and DDR4; single SATA 6 Gbps port for local mass storage.
• Networking and High-speed I/O  Flexible Ethernet options (multiple 1GbE ports or a 10GbE plus additional 1GbE ports), USB 3.0 (3 ports) with PHY, and multiple PCIe Gen2 interfaces enabled via a four-lane multi‑protocol SerDes.
• Packet and Data Path Acceleration  Frame Manager and the QorIQ Data Path Acceleration Architecture (DPAA) provide hardware packet parsing, classification and offload engines to reduce CPU overhead for networking tasks.
• Security  Secure Boot and ARM® TrustZone® support, plus an integrated security engine (SEC 5.4) capable of in-line IPsec processing for secure communications.
• Package and Thermal Range  621-FCPBGA (21×21 mm) surface-mount package with industrial qualification and an operating temperature range of −40 °C to 105 °C.

Typical Applications

• Branch and Edge Routers  Use the LS1043AXE7KQB for compact branch office routers and vCPE platforms where multi-port Ethernet and packet offload reduce system CPU load.
• IoT and Multi‑protocol Gateways  Deploy as the processing core in multi-protocol IoT gateways that require mixed I/O, secure connectivity and industrial temperature support.
• Industrial Control and PLCs  Integrate into industrial PLC and control systems that benefit from deterministic networking, integrated storage and extended temperature operation.
• Security Appliances  Implement in network security appliances that require on-chip cryptographic acceleration, Secure Boot and TrustZone® for trusted execution.

Unique Advantages

• Highly integrated networking I/O: Consolidates multiple Gigabit/10 Gigabit Ethernet options, PCIe, USB 3.0 and SATA to reduce board-level complexity and BOM count.
• Packet offload and acceleration: Frame Manager and DPAA reduce CPU overhead for networking workloads, enabling higher aggregate throughput with lower host CPU utilization.
• Security-ready platform: Secure Boot, TrustZone® and an integrated SEC engine support in-line IPsec to simplify secure system design.
• Industrial-grade robustness: Industrial qualification and a −40 °C to 105 °C operating range make the device suitable for harsh environments and fanless designs.
• Compact BGA package: 621-FCPBGA (21×21 mm) package supports small-form-factor system designs and surface-mount assembly.
