LS1043ASN8KQB

Microprocessors Overview

The NXP LS1043ASN8KQB is a quad-core, 64-bit ARM Cortex-A53 communications processor operating at up to 1.6 GHz. It features a 1 MB L2 cache and integrates the QorIQ Data Path Acceleration Architecture (DPAA) for hardware packet processing. The device includes an integrated Security Engine (SEC 5.4), four-lane 10 GHz SerDes, and supports DDR3L/4 memory. Connectivity options comprise up to six Gigabit Ethernet ports, three PCIe Gen 2.0 interfaces, three USB 3.0 controllers, and SATA 3.0.

Microprocessors Feature Summary

• Integrates QUICC Engine technology for legacy protocol support including HDLC, TDM, and PROFIBUS.
• Provides hardware-based virtualization via CoreLink CCI-400 coherent interconnect and SMMU.
• Delivers high-speed security processing with integrated SEC 5.4 supporting IPsec, SSL, and DTLS.
• Supports fan-less platform designs with total system power as low as 5 W.

Microprocessors Applications

• Integrated services gateways
• Branch office routers
• vCPE and edge equipment
• Multi-protocol IoT gateways
• Industrial PLC and control systems

Microprocessors Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm exact package type, temperature range, and security configuration. Ensure compatibility with required DDR3L or DDR4 memory standards and validate that the selected variant meets the thermal requirements of the target embedded networking application.

Microprocessors Selection Notes

Select this processor for applications requiring high performance per watt in small-form-factor designs. It is suitable for environments needing robust I/O flexibility and legacy protocol support via QUICC Engine. Consider the integrated DPAA for offloading network tasks from the CPU complex to maximize efficiency.

Microprocessors Part Context

The LS1043A belongs to the QorIQ Layerscape family, designed for enterprise edge and industrial infrastructure. It succeeds dual-core 32-bit products by offering up to four 64-bit cores. The architecture emphasizes energy efficiency and hardware acceleration for networking workloads in value-tier communication processors.

Microprocessors Replacement Considerations

The LS1023A serves as a dual-core alternative within the same series. For higher core counts, the LS1046A or LS1088A are compatible successors in the Layerscape portfolio.
