LS1043ASE8KQB

The LS1043ASE8KQB is an NXP QorIQ Layerscape microprocessor IC built on a quad-core ARM® Cortex®-A53 64-bit architecture running at 1.0 GHz. It is targeted at embedded networking and industrial infrastructure applications where integration, deterministic packet handling and secure boot capabilities are required.

Designed for small-form-factor networking and edge equipment, the LS1043A family combines a quad-core CPU complex with QorIQ Data Path Acceleration Architecture (DPAA) and flexible I/O to enable high-throughput packet processing, hardware-accelerated security and multi-protocol interface support.

Key Features

• Core & Memory Quad ARM® Cortex®-A53 64-bit cores at 1 GHz with a large 1 MB L2 cache to balance compute performance and efficiency. Supports DDR3L and DDR4 memory controllers for system memory flexibility.
• Networking & Packet Offload Integrated DPAA and Frame Manager for hardware packet parsing, classification and policing. Ethernet configurations include multiple 1 GbE ports or a combination of 10 GbE and 1 GbE ports as specified.
• High-speed SerDes & PCIe Four-lane, 10 GHz multi-protocol SerDes and up to three PCI Express® Gen2 interfaces provide flexible high-speed connectivity for expansion and front-panel PHYs.
• Storage & USB Single SATA 6 Gbps port and three USB 3.0 ports (with PHY) for peripheral and storage connectivity.
• Security Hardware security features include Secure Boot and ARM® TrustZone® plus an integrated security engine (SEC 5.4) to support inline IPsec and cryptographic offload.
• I/O Flexibility & Legacy Support Integrated QUICC Engine technology enables glue-less support for legacy interfaces such as HDLC, TDM and PROFIBUS, simplifying board-level design.
• Package & Thermal Supplied in a 780-FCPBGA (23×23) surface-mount package. Operating temperature range is 0 °C to 105 °C.
• Qualification & Compliance Device qualification is listed as Consumer and the part is RoHS compliant.

Typical Applications

• Branch Office Routers — Quad-core processing, hardware packet parsing and multiple Ethernet options enable high-throughput routing and firewall duties in compact appliances.
• vCPE and Edge Equipment — Integration of DPAA, PCIe and USB 3.0 supports virtualized CPE platforms and edge compute nodes with reduced CPU overhead.
• Multi-protocol IoT Gateways — Flexible SerDes and QUICC Engine support facilitate mixed-protocol connectivity and legacy industrial interfaces for gateway designs.
• Industrial PLC & Control — Deterministic packet handling, TrustZone and Secure Boot provide a foundation for secure control and communications in industrial applications.
• Security Appliances — On-chip security engine and hardware IPsec offload enable encrypted traffic handling with minimal general-purpose CPU impact.

Unique Advantages
