OMAPL138BZCE3

The OMAPL138BZCE3 is a 32-bit embedded microprocessor IC built around a 375 MHz ARM926EJ-S core, paired with a C674x-class signal-processing co-processor. It targets embedded applications that require a balanced combination of general-purpose control and DSP-class signal processing in a single, highly integrated device.

With on-chip interfaces for Ethernet, SATA and USB, alongside display support and integrated security features, the device is suited to embedded control, communications and storage-aware systems where integration, peripheral breadth and software support matter.

Key Features

• Processor and DSP  ARM926EJ-S 32‑bit processor core running at 375 MHz, with a C674x-class DSP co-processor for signal-processing tasks.
• Memory architecture  ARM9 memory architecture with 16 KB instruction and 16 KB data caches, 8 KB vector RAM and 64 KB ROM. C674x two-level cache with 32 KB L1P, 32 KB L1D and a 256 KB L2 unified mapped RAM/cache plus 128 KB shared RAM.
• External memory support  EMIFA for NOR/NAND (8- or 16-bit data), 16-bit SDRAM support and a DDR2/mobile DDR memory controller with support up to a 256‑MB address space.
• High-throughput peripherals  Integrated 10/100 Mbps Ethernet (1), SATA 3 Gbps (1), and both USB 1.1 + PHY and USB 2.0 + PHY interfaces for broad connectivity and storage options.
• Display support  On-chip LCD display controller for embedded user-interface implementations.
• DMA and transfer engines (EDMA3)  Enhanced DMA controller with up to 64 independent DMA channels and 16 QDMA channels for efficient data movement and reduced CPU overhead.
• Security  Built-in boot security and cryptography features to support secure boot and encrypted operations.
• Packaging and mounting  361‑ball NFBGA (13 × 13 mm) supplier device package, surface-mount, tray packaging suitable for volume assembly.
• Software support  Software ecosystem includes TI DSP/BIOS, Chip Support Library and DSP library support as documented for the OMAP-L138 series.

Typical Applications

• Embedded control systems  Use the ARM926EJ-S core for control and system management while leveraging the C674x DSP for compute‑intensive signal processing tasks.
• Networked appliances  Integrated 10/100 Mbps Ethernet and USB interfaces make the part suitable for connected gateway and appliance designs requiring moderate networking throughput.
• Storage and media appliances  SATA 3 Gbps combined with USB and DMA resources supports embedded storage controllers, media appliances and devices needing local storage interfaces.
• Human‑machine interfaces  On-chip LCD controller and embedded memory/cache resources enable compact implementations of operator displays and control panels.

Unique Advantages

• Balanced ARM + DSP integration: Combines a 375 MHz ARM926EJ-S application core with a C674x DSP co-processor to consolidate control and signal-processing workloads on one chip, reducing system BOM and board complexity.
• Broad peripheral set: Native Ethernet, SATA and multiple USB PHYs provide flexible options for networking, storage and peripheral connectivity without many external controllers.
• Rich memory subsystem: Multi-level caches, unified L2 RAM/cache and shared RAM improve data throughput and deterministic performance for mixed-control and DSP tasks.
• High-efficiency data movement: EDMA3 with numerous DMA/QDMA channels offloads data transfers from the CPU and DSP, improving overall system efficiency.
• Built-in security primitives: Boot security and cryptography features enable secure device provisioning and protected operation where required.
• Proven software libraries: Availability of TI DSP/BIOS, Chip Support Library and DSP libraries facilitates development and accelerates time to market.
