• High-efficiency CPU Subsystem — 1 MB L2 cache and an eight-stage pipeline architecture to deliver strong performance per watt for value-tier communications processors.
• Data Path Acceleration — Integrated QorIQ Data Path Acceleration Architecture (DPAA) and a Frame Manager for hardware packet parsing, classification and policing to reduce CPU overhead and support up to 10 Gb/s aggregate performance.
• Flexible High-speed Interfaces — Multi-protocol 4-lane SerDes supporting up to six Gigabit Ethernet ports, combinations including a 10GbE port, three PCIe Gen2 ports and a SATA 3.0 (6 Gbps) port.
• USB and Peripheral Support — Three USB 3.0 controllers with PHY for high-speed host and device connectivity.
• Integrated Security — Hardware security features including Secure Boot, ARM TrustZone® and an integrated SEC 5.4 security engine enabling in-line IPsec.
• Legacy Protocol Support — Integrated QUICC Engine technology for glue-less HDLC, TDM or PROFIBUS support in industrial designs.
• Memory Support — Compatible with DDR3L and DDR4 memory controllers for system memory flexibility.
• Industrial Qualification and Thermal Range — Industrial qualification with an operating temperature range of -40 °C to 105 °C for robust field deployments.
• Package and Mounting — 780-FCPBGA (23 x 23 mm), surface-mount package designed for small-form-factor boards; RoHS compliant.
• No Graphics Acceleration — Focused as a communications and control processor without graphics acceleration, optimizing die area for packet and compute engines.

Typical Applications

• Integrated Services and Branch Office Routers — Multi-core compute and packet acceleration meet routing and services needs in compact edge routers.
• vCPE and Edge Equipment — Offload engines and virtualization-friendly features support virtualized customer premises equipment and edge appliances.
• Multi‑Protocol IoT Gateways — Flexible interfaces and security engines enable protocol bridging, secure connectivity and local processing for IoT gateways.
• Industrial PLC and Control — Industrial temperature rating, QUICC Engine support and deterministic interfaces make the device suitable for control systems and protocol conversion.
• Security Appliances — Integrated SEC engine and frame processing enable hardware-accelerated IPsec and packet inspection for security-focused network appliances.

Unique Advantages

• Balanced Multi-core and Offload Architecture: Quad-core Cortex-A53 combined with DPAA and Frame Manager reduces CPU load for packet processing and improves application throughput.
• Comprehensive I/O Integration: On-chip SerDes, multiple Ethernet options, PCIe, SATA and USB 3.0 reduce external components and simplify board-level design.
• Industrial-ready Thermal Range: Rated from -40 °C to 105 °C for deployments in harsh or outdoor edge environments.
• Security Built In: Secure Boot, TrustZone® and an integrated security engine enable secure device boot and accelerated crypto operations for in-line network security.
• Legacy Protocol Support: QUICC Engine integration removes the need for separate legacy protocol controllers, lowering BOM and board area for industrial protocols.
• Small-form-factor Packaging: 780-FCPBGA (23×23 mm) package supports compact, fanless system designs.
