Key Features

• Core & CPU – Quad ARM® Cortex®-A53 64‑bit cores at 1 GHz with a large 1 MB L2-cache and an efficient pipeline for improved performance per watt.
• Memory – Integrated controllers supporting DDR3L and DDR4 memory technologies for flexible system memory design.
• High‑speed SerDes & PCIe – Four‑lane, 10 GHz multi‑protocol SerDes and up to three DMA‑controlled PCI Express® Gen2 ports for high‑speed peripheral connectivity.
• Ethernet & Networking – Configurable Ethernet options including multiple 1 GbE ports or a combination of 10 GbE and 1 GbE to suit diverse networking topologies; includes Frame Manager for hardware packet parsing and classification.
• Storage & USB – Single SATA 6 Gbps port and three USB 3.0 ports with PHY support for high‑speed storage and host connectivity.
• Security & Trust – Secure Boot and ARM® TrustZone® support plus an integrated security engine (SEC 5.4) for in‑line IPsec and cryptographic offload.
• Offload & Acceleration – QorIQ Data Path Acceleration Architecture (DPAA) and Frame Manager reduce CPU overhead for packet processing, enabling multi‑gigabit throughput.
• System Integration – CoreLink CCI‑400 coherent interconnect and SMMU for hardware‑enforced memory access controls for accelerators and virtualized environments.
• Package & Thermal – 780‑FCPBGA (23×23) surface‑mount package; operating temperature range 0 °C to 105 °C; RoHS compliant.

Typical Applications

• Branch Office Routers – Multi‑core processing and multiple Ethernet interfaces enable routing and security functions in compact branch systems.
• vCPE and Edge Equipment – Hardware offload and DPAA support multi‑gigabit throughput with reduced CPU load for virtualized customer premises equipment.
• Multi‑protocol IoT Gateways – Flexible SerDes, diverse Ethernet options and integrated security make it suitable for protocol conversion and edge aggregation.
• Industrial Control & PLCs – Small‑form‑factor design and broad I/O support meet requirements for industrial control, PLC and automation applications.
• Security Appliances – Integrated SEC engine and Frame Manager enable in‑line IPsec and packet processing for appliance‑class security solutions.

Unique Advantages

• Highly integrated I/O: Multiple Gigabit/10 Gigabit Ethernet options, PCIe, USB 3.0 and SATA reduce external components and simplify board design.
• Packet offload capability: DPAA and Frame Manager handle packet parsing, classification and policing to lower CPU overhead for network data paths.
• Security‑ready platform: Secure Boot, TrustZone® and an integrated SEC engine provide a foundation for secure system designs and in‑line cryptographic processing.
• Memory flexibility: Support for DDR3L and DDR4 memory controllers lets designers choose cost or performance‑optimized memory subsystems.
• Compact package for small systems: 780‑FCPBGA (23×23) surface‑mount package and features targeted for fanless, small‑form‑factor designs reduce BOM and mechanical complexity.
