• Signal-Processing Co-Processor  Includes a C674x DSP co-processor for signal-processing workloads and CP15 for system control, enabling offload of compute-intensive tasks.
• Memory and External Memory Interfaces  SDRAM memory controller is provided; datasheet series details include external memory interface options (EMIFA) and DDR2 support for flexible memory subsystem implementation.
• Display and Host Interfaces  On-chip LCD display controller and Host Port Interface (HPI) support integration of local displays and external host connections.
• High-Speed I/O and Storage  Integrated peripherals include 10/100 Mbps Ethernet (1), SATA 3 Gbps (1), USB 1.1 + PHY (1) and USB 2.0 + PHY (1) for networking, peripheral and storage connectivity.
• Security Features  Boot security and cryptography features are available to help protect boot integrity and support secure functions.
• Package and Mounting  Supplied in a 361‑NFBGA (13×13) package, intended for surface-mount PCB assembly to support compact system designs.
• Operating Range and Compliance  Commercial-grade device with an operating temperature range of 0 °C to 90 °C and RoHS compliance for environmental standards.

Typical Applications

• Embedded Networking and Gateways  Use Ethernet, USB and SATA interfaces to enable networked appliances, edge gateways or protocol-conversion devices that require integrated I/O and storage.
• Signal Processing Systems  Combine the ARM core with the C674x DSP co-processor for applications needing real-time signal processing or algorithm acceleration.
• User Interface and Display Controllers  Integrate local display functionality using the on-chip LCD controller for human-machine interfaces in embedded products.
• Compact Embedded Controllers  The 361‑NFBGA package and surface-mount mounting are suitable for space-constrained control platforms that require a mix of compute and peripheral connectivity.

Unique Advantages

• Integrated Processor Pairing  ARM926EJ-S CPU plus a C674x DSP co-processor lets designers partition control and signal-processing tasks without adding discrete DSP devices.
• Wide Peripheral Set  On-chip Ethernet, SATA, USB 1.1/2.0 and LCD controller reduce external component count and simplify system-level design.
• On-Device Security  Built-in boot security and cryptography features help protect system boot and secure operations without external security ICs.
• Compact, Surface-Mount Package  361‑NFBGA (13×13) package enables dense PCB layouts for compact embedded systems.
• Commercial Temperature and RoHS Compliance  Rated 0 °C to 90 °C for commercial applications and RoHS-compliant for environmental requirements.
