• External Memory Interfaces  Support for SDRAM and DDR2/Mobile DDR memory controllers for system memory expansion and high-bandwidth data buffering.
• High-Speed Interfaces  Integrated 10/100 Mbps Ethernet, SATA 3 Gbps, USB 1.1 and USB 2.0 ports with PHYs, and an LCD display controller for connectivity and I/O-rich embedded systems.
• DMA and Peripherals  Enhanced EDMA3 controller with multiple channels and transfer controllers to offload data movement and improve real-time throughput.
• Security and Boot  Built-in boot security and cryptography features to support secure system boot and protected data handling.
• Package and Thermal  361-pin NFBGA (16×16 mm) surface-mount package rated for industrial operation from −40 °C to 105 °C.

Typical Applications

• Industrial Control  Real-time control and signal-processing tasks in industrial automation where deterministic DSP acceleration and an ARM host processor are required.
• Communications Equipment  Networking and protocol handling using integrated Ethernet and USB interfaces alongside DSP-based packet processing or codec functions.
• Storage and Embedded NAS  Compact storage appliances and embedded NAS designs benefiting from on-chip SATA 3 Gbps and Ethernet connectivity.
• Multimedia and Signal Processing  Voice, audio, and other DSP-centric workloads that leverage the C674x signal-processing core with the ARM MPU coordinating system-level tasks.

Unique Advantages

• Integrated MPU + DSP Architecture: Combines an ARM926EJ-S application processor with a C674x-class DSP to consolidate control and compute-intensive signal processing on a single device, reducing BOM and inter-chip latency.
• Rich I/O Set: On-chip Ethernet, SATA, USB (1.1 and 2.0 with PHYs), LCD controller and HPI interfaces enable a wide range of system designs without extensive external glue logic.
• Industrial Temperature Rating: Specified for −40 °C to 105 °C operation to meet the environmental demands of industrial and ruggedized deployments.
• Security-Ready: Boot security and cryptographic capabilities facilitate secure system startup and data protection strategies.
• Compact Surface-Mount Package: 361-pin NFBGA (16×16 mm) package provides a high pin-count solution in a compact footprint suitable for space-constrained embedded boards.
