• Data Path Acceleration Built‑in Data Path Acceleration Architecture (DPAA) and on‑chip offload engines to enable high throughput (up to ~10 Gb/s series capability) while minimizing general‑purpose CPU load.
• High‑speed Interfaces Single SATA 6 Gbps port and up to three USB 3.0 ports with PHY; multi‑protocol SerDes supports high‑speed peripheral and network interfaces.
• PCI Express & Legacy Support Multiple DMA‑controlled PCIe ports and integrated QUICC Engine technology for glue‑less HDLC, TDM or PROFIBUS support for legacy industrial protocols.
• Security & Virtualization Secure Boot and ARM® TrustZone® support plus CoreLink CCI‑400 and SMMU for hardware‑enforced memory access controls for accelerators and peripherals operating on behalf of virtual machines.
• Industrial Grade & Packaging Industrial qualification with operating temperature range of −40 °C to 105 °C; supplied in a 621‑FCPBGA (21×21) surface‑mount package. RoHS compliant.

Typical Applications

• Edge Networking & Routers Small‑form‑factor branch routers and vCPE appliances that require multi‑core packet processing and hardware packet handling.
• Industrial Control & PLCs Embedded controllers and PLC platforms benefitting from deterministic networking, legacy protocol support and extended temperature operation.
• IoT & Gateway Devices Multi‑protocol IoT gateways that need flexible I/O, security features and offload engines to manage device traffic and secure connections at the edge.
• Security Appliances Network security appliances leveraging DPAA and the integrated security engine to perform inline IPsec and cryptographic processing with reduced CPU impact.

Unique Advantages

• Integrated Networking and Offload: On‑chip Frame Manager and DPAA offload engines reduce CPU load for packet processing, enabling higher throughput without adding external accelerators.
• Flexible I/O in a Compact Package: Multi‑protocol SerDes, SATA, USB 3.0 and PCIe connectivity in a 21×21 FCPBGA allow dense system designs and small PCB footprints.
