OMAPL138AZWTA3

The OMAPL138AZWTA3 from Texas Instruments is a microprocessor IC in the OMAP-L13x series that combines an ARM926EJ-S application core with a dedicated C674x signal-processing coprocessor. Designed for embedded applications, the device integrates a range of interfaces and security features to support systems that require processing and I/O consolidation.

This single-core, 32-bit processor package is supplied in a 361-ball BGA and is RoHS compliant, making it suitable for surface-mount assembly in embedded product designs.

Key Features

• Core and Coprocessors The device uses an ARM926EJ-S core (single 32-bit core) and includes coprocessors for signal processing (C674x) and system control (CP15) to offload specialized tasks.
• Display Interface Includes an LCD display interface controller to support local visual output and user interfaces.
• Network and Storage Interfaces Integrated 10/100Mbps Ethernet and a SATA 3Gbps interface provide wired networking and storage connectivity options.
• USB Connectivity Provides both USB 1.1 + PHY and USB 2.0 + PHY interfaces for external device and host connectivity.
• Security Features Built-in boot security and cryptography functions support secure device boot and data protection workflows.
• Packaging and Mounting Supplied in a 361-LFBGA / 361-NFBGA (16×16) package for surface-mount applications, facilitating compact board-level integration.
• Regulatory Compliance RoHS compliant to meet lead-free assembly requirements.
• Graphics Acceleration No dedicated graphics acceleration is provided, focusing the device on processing and I/O integration.

Typical Applications

• Embedded signal processing Use the ARM926EJ-S core together with the C674x coprocessor to implement DSP-heavy algorithms in compact embedded systems.
• Human–machine interfaces The on-chip LCD controller supports devices that require local display capability for status, controls, or operator feedback.
• Networked systems Integrated 10/100Mbps Ethernet and SATA 3Gbps enable networking and local storage functions in communications or data-logging equipment.
• Peripheral-rich devices Dual USB PHYs (USB 1.1 and USB 2.0) allow flexible connection to external peripherals and hosts in embedded products.

Unique Advantages

• Combined application and DSP processing: The ARM926EJ-S core plus C674x signal-processing coprocessor lets designers partition control and compute tasks across dedicated processors.
• Comprehensive I/O integration: Ethernet, SATA and dual USB PHYs reduce the need for external controllers and simplify board-level design.
• Security-ready boot and cryptography: Built-in boot security and cryptographic features support secure startup and data protection without additional components.
• Surface-mount BGA packaging: The 361-LFBGA / 361-NFBGA (16×16) package enables high-density PCB layouts for space-constrained embedded designs.
• Series continuity: As part of the OMAP-L13x series from Texas Instruments, the component aligns with a consistent family approach for embedded system designs.
