• Storage and USB  One SATA 6 Gbps port and two USB 3.0 ports with PHY for high-performance storage and peripheral connectivity.
• Offload and Packet Processing  QorIQ Data Path Acceleration Architecture (DPAA) and Frame Manager support hardware packet parsing, classification and offload functions to reduce CPU overhead and enable greater than 10 Gb/s system throughput.
• Security  Hardware security features including Secure Boot and ARM TrustZone® to enable trusted execution and platform integrity.
• Legacy and Protocol Support  Integrated QUICC Engine technology and SEC 5.4 security engine for glue-less support of legacy interfaces and in-line IPsec processing.
• PCIe and SerDes  Multiple DMA-controlled PCI Express Gen2 ports and a multi-protocol SerDes provide flexible connectivity to accelerators and high-speed peripherals.
• Package and Thermal  621-FCPBGA (21×21) surface-mount package; operating temperature 0 °C to 105 °C.
• Compliance  RoHS compliant.

Typical Applications

• Branch office routers: Compact routing platforms that leverage integrated Ethernet ports and packet offload to meet WAN/LAN throughput requirements in small-form-factor designs.
• vCPE and edge equipment: Virtualized customer premises equipment and edge appliances that benefit from 64-bit compute, security features and DPAA offload to support multiple services.
• Multi-protocol IoT gateways: Gateways that require flexible SerDes, QUICC Engine compatibility and mixed Ethernet configurations for protocol translation and device aggregation.
• Industrial PLC and control: Industrial control systems that need reliable operation within 0 °C to 105 °C and integrated interfaces for real-time connectivity and legacy protocol support.
• Security appliances: Inline IPsec and hardware-accelerated cryptography via the integrated security engine for secure networking functions.

Unique Advantages

• Highly integrated network-focused platform: On-chip Ethernet configurations, SATA and USB reduce external components and simplify BOM for compact networking appliances.
• Offload architecture for higher throughput: DPAA and Frame Manager provide hardware packet processing and classification to lower CPU load and enable system throughput beyond 10 Gb/s.
• Flexible interface mix: Multi-protocol SerDes, multiple PCIe Gen2 ports and QUICC Engine support enable broad peripheral and legacy protocol connectivity without extensive glue logic.
• Built-in security primitives: Secure Boot and TrustZone® support help establish platform trust and simplify secure deployment models for edge devices.
• Optimized for small-form-factor designs: Purpose-built Layerscape implementation targets BOM reduction, lower-power supplies and simplified clocking for compact industrial and networking equipment.
• Industrial-capable thermal range: 0 °C to 105 °C operating range supports deployment in a variety of edge and industrial environments.
