Key Features

• Core and CPU subsystem — Four ARM® Cortex®‑A72 cores (64‑bit) arranged as a single cluster sharing a 2 MB L2 cache; up to 1.8 GHz operation with 32 KB L1 data and 48 KB L1 instruction caches per core.
• Memory — One 32‑bit/64‑bit DDR4 SDRAM controller with ECC and interleaving support for robust system memory operation; DDR4 rated up to 2.1 GT/s.
• Networking and packet acceleration — Multiple Ethernet interfaces including two 10 GbE, one 2.5 GbE and four 1 GbE ports; Data Path Acceleration Architecture (DPAA) with FMan, QMan and BMan for packet parsing, queuing and buffer management; IEEE 1588 support.
• High‑speed peripheral interfaces — Eight SerDes lanes enabling flexible high‑speed I/O, three PCIe 3.0 controllers, one SATA 6 Gbit/s controller and three USB 3.0 controllers with integrated PHY.
• Flash and peripheral controllers — Integrated flash controller supporting NAND and NOR, QSPI and SPI controllers, enhanced SD host controller supporting SD 3.0/eMMC 4.4/4.5.
• Security — Secure Boot and ARM TrustZone® support plus cryptography acceleration via the SEC block for offloading security workloads.
• System and reliability features — Hardware acceleration blocks, queue DMA (qDMA), enhanced DMA (eDMA), global interrupt controller (GIC) and thermal monitoring unit (TMU) for system management and reliability.
• Package and environmental — 780‑FBGA (780‑FCPBGA) package, 23 mm × 23 mm, surface mount; operating temperature range 0 °C to 105 °C; RoHS compliant and consumer qualification.

Typical Applications

• Network and security appliances — Multi‑core processing with DPAA and multiple 10 GbE/1 GbE interfaces enables packet processing, firewalling and secure gateway functions.
• Edge compute and intelligent gateways — High single‑thread and multicore performance combined with PCIe and USB connectivity for local analytics and edge services.
• Storage and NAS appliances — SATA 6 Gbit/s and PCIe connectivity support storage subsystem integration and data offload tasks.
• Embedded platforms requiring secure boot — Built‑in Secure Boot and TrustZone® support provide a foundation for trusted platform deployment.

Unique Advantages

• Highly integrated compute and I/O: Combines four Cortex‑A72 cores with multiple high‑speed interfaces (PCIe, SATA, USB, SerDes) to reduce system BOM and simplify board design.
• Dedicated packet and buffer acceleration: DPAA (FMan/QMan/BMan) offloads networking tasks from cores, enabling more efficient packet handling and scheduling.
• Hardware crypto and secure boot: SEC acceleration and TrustZone® plus Secure Boot support help secure data paths and system boot integrity without heavy CPU overhead.
• Robust memory subsystem: DDR4 controller with ECC and interleaving support improves data integrity and supports higher memory throughput.
• Compact, production‑ready package: 780‑FCPBGA (23 × 23 mm) surface‑mount package with 0 °C to 105 °C operating range for consumer‑qualified embedded designs.
