OMAPL138EZWTA4

The OMAPL138EZWTA4 is an embedded microprocessor device based on the ARM926EJ-S architecture and the OMAP-L13x series. It combines an ARM926EJ-S RISC MPU running at 456 MHz with signal-processing capabilities from the C674x DSP family to address compute and real‑time processing needs in industrial embedded systems.

Designed for industrial-grade applications, this device delivers a broad set of on-chip peripherals and memory interfaces—enabling compact, integrated designs that require deterministic processing, connectivity and storage interfaces in a surface-mount 361-NFBGA (16×16) package.

Key Features

• Core & DSP ARM926EJ-S 32‑bit processor core at 456 MHz combined with C674x-class DSP signal processing support for offloading compute-intensive tasks.
• Memory & Cache Integrated memory architecture detailed in the OMAP-L1x family including L1/L2 cache and shared on-chip RAM; external memory support includes SDRAM and DDR2/mDDR options and EMIFA for NOR/NAND devices.
• High-performance I/O Multiple host interfaces including USB 1.1 and USB 2.0 with PHY, a single 10/100 Mbps Ethernet port, and an HPI for external host communication.
• Storage & Media Interfaces On-chip SATA support (3 Gbps) and an LCD controller enable storage and display integration for embedded systems.
• DMA & Peripherals Enhanced DMA (EDMA3) with extensive channel support and multiple UARTs and SPI interfaces provide flexible, low-latency peripheral connectivity.
• Security & System Control Boot security and cryptography features along with system control coprocessor (CP15) for secure boot and protected system operation.
• Industrial-grade Packaging & Temperature Surface-mount 361-NFBGA (16×16) package rated for an operating temperature range of −40 °C to 105 °C and RoHS compliant.

Typical Applications

• Industrial Control: Real-time control and signal processing for factory automation and machine control using the ARM core alongside the C674x DSP.
• Networking & Connectivity: Embedded gateways and communication devices leveraging the integrated 10/100 Mbps Ethernet and USB interfaces.
• Storage & Data Acquisition: Embedded systems requiring local storage and high-speed transfers benefit from the onboard SATA 3 Gbps support and EDMA3 controller.
• HMI and Display Systems: Human‑machine interfaces that use the on-chip LCD controller for panels and operator displays in industrial environments.

Unique Advantages

• Dual processing capability: ARM926EJ-S plus C674x DSP support enables separation of control and compute-intensive signal processing without adding discrete processors.
• Comprehensive memory interfaces: Built-in support for SDRAM, DDR2/mDDR and EMIFA for NOR/NAND simplifies system memory design and expands addressable memory options.
• Broad peripheral set: Integrated USB 1.1/2.0, Ethernet, SATA and multiple serial interfaces reduce external components and simplify BOM.
• Designed for industrial environments: −40 °C to 105 °C operating range and a compact 361-NFBGA surface-mount package enable deployment in rugged systems.
• Security-focused features: On-chip boot security and cryptography support help protect firmware and system integrity at startup.
