• High‑Speed Networking  Flexible Ethernet options including configurations with up to six 1 GbE ports or a combination of one 10 GbE and five 1 GbE ports; IEEE 1588 support is available.
• Data Path Acceleration  QorIQ Data Path Acceleration Architecture (DPAA) and Frame Manager provide hardware packet parsing, classification and policing to offload packet processing from the general‑purpose cores.
• High‑Speed SerDes and Interfaces  Four‑lane, 10 GHz multi‑protocol SerDes with support for up to three PCIe interfaces (DMA controlled), one SATA 6 Gbps port and three USB 3.0 ports plus PHY.
• Integrated Security  Secure Boot and ARM TrustZone® support, complemented by an integrated security engine (SEC 5.4) to enable inline IPsec and other cryptographic offloads.
• System Coherency and Virtualization  CoreLink CCI‑400 coherent interconnect and SMMU (I/O MMU) provide hardware memory access controls for accelerators and peripherals used with virtual machines.
• Industrial Qualification & Temperature Range  Industrial qualification with an operating temperature range of −40 °C to 105 °C.
• Package & Mounting  621‑FCPBGA surface‑mount package (21×21 mm) for compact, board‑level integration.

Typical Applications

• Integrated Services  Consolidated service platforms that combine control, management and data plane functions in a compact embedded system.
• Branch Office Routers  Small‑form‑factor routing and security appliances leveraging integrated Ethernet, DPAA offloads and inline cryptography for WAN/LAN throughput.
• vCPE and Edge Equipment  Virtualized customer premises equipment and edge devices that benefit from 64‑bit processing, SMMU support and offload engines for scalable packet processing.
• Multi‑protocol IoT Gateways  Gateways requiring mixed protocol support, serial/TDM integration via QUICC Engine technology, and robust connectivity options.
• Industrial PLC & Control  Industrial control systems needing industrial temperature operation, deterministic packet handling and integrated legacy protocol support.

Unique Advantages

• Quad‑Core 64‑Bit Processing: Four Cortex‑A53 cores at 1.6 GHz with 1 MB L2 cache deliver higher CPU performance per watt for compute‑intensive embedded workloads.
• Packet Processing Offload: DPAA and Frame Manager hardware enable up to multi‑Gb/s performance with reduced CPU overhead for networking tasks.
• Comprehensive I/O Integration: Multi‑protocol SerDes, multiple Gigabit/10 Gigabit Ethernet options, 3× USB 3.0, SATA 3.0 and 3× PCIe simplify board design and reduce external components.
• Security and Virtualization Support: Secure Boot, TrustZone and an integrated security engine (SEC 5.4), combined with CoreLink CCI‑400 and SMMU, support secure, virtualized deployments and controlled DMA access.
• Industrial‑Grade Operation: Qualified for industrial use with −40 °C to 105 °C operating range for reliable field operation in demanding environments.
• BOM and System Optimization: Purpose‑built for small‑form‑factor and fanless designs with BOM optimizations (low‑layer PCB, simplified power and single‑clock design) to reduce system cost and complexity.
