Key Features

• Core  Dual ARM® Cortex®-A53 64-bit processors at 1.2 GHz providing a two-core CPU complex for general-purpose compute.
• Cache and Interconnect  Includes a large L2-cache and ARM CoreLink CCI-400 coherent interconnect with SMMU for hardware-enforced memory controls (as described for the LS1023A family).
• Memory  Supports DDR3L and DDR4 memory controllers for flexible system memory choices.
• Networking and High‑Speed I/O  Multi-protocol four-lane SerDes (10 GHz) with support for multiple Ethernet configurations (up to six Gigabit Ethernet ports or a mix of 10GbE and 1GbE as specified), three PCIe 2.0 DMA-controlled ports, a single SATA 6Gbps (SATA 3.0) port, and USB 3.0 (2) with PHY.
• Data Path Acceleration  Integrates QorIQ Data Path Acceleration Architecture (DPAA) offload engines and Frame Manager functions for hardware packet parsing, classification and policing to reduce CPU overhead.
• Security  Implements Secure Boot and ARM TrustZone® along with an integrated security engine (SEC) for in-line IPsec and cryptographic offload.
• Package and Mounting  780-ball FCPBGA package (23 × 23 mm) designed for surface-mount assembly.
• Qualification and Operating Range  Industrial qualification with an operating temperature range of −40 °C to 105 °C.
• Design Targets  Purpose-built for fanless, small-form-factor networking and industrial designs with BOM optimizations for low-layer PCBs, simplified power supply and single-clock system design (as described for the LS1023A family).

Typical Applications

• Branch Office Routers: Compact routing platforms requiring multi-port Ethernet, hardware packet processing and secure transport.
• vCPE and Edge Appliances: Virtualized customer premises equipment and edge devices that benefit from dual-core 64-bit processing and DPAA offloads.
• IoT and Multi‑Protocol Gateways: Gateways handling protocol conversion and packet classification for IoT deployments.
• Industrial PLC and Control: Industrial control systems needing industrial temperature operation and robust I/O integration.
• Security Appliances: Network security devices leveraging integrated SEC and Frame Manager capabilities for inline IPsec and packet processing.

Unique Advantages

• Balanced dual‑core 64‑bit performance: ARM Cortex‑A53 cores at 1.2 GHz deliver general-purpose compute for control-plane and edge workloads.
• Integrated high‑speed I/O: Multi-protocol SerDes, PCIe, SATA and USB 3.0 reduce the need for external controllers and simplify system BOM.
• Packet offload and frame management: DPAA and Frame Manager capabilities provide hardware packet parsing and classification to lower CPU overhead.
• Built‑in security primitives: Secure Boot, TrustZone® and an integrated security engine enable secure device boot and inline cryptographic processing.
• Industrial operating range: −40 °C to 105 °C qualification supports deployment in harsh environments.
• Compact BGA package: 780-FCPBGA (23×23 mm) surface-mount package enables small-form-factor board designs.
