OMAPL138BZWT3

The OMAPL138BZWT3 is a 32-bit microprocessor IC based on the ARM926EJ-S core running at 375 MHz, packaged in a 361‑pin NFBGA (16 × 16) surface‑mount package. It combines an ARM926EJ‑S application processor with a high‑performance TMS320C674x signal‑processing DSP architecture and a broad set of on‑chip system interfaces.

Targeted at embedded designs that require CPU/DSP processing, rich peripherals and integrated I/O, this device delivers system-level integration for applications needing real‑time signal processing, storage and network connectivity while reducing board BOM and interface bridging.

Key Features

• Processing Cores  ARM926EJ‑S 32‑bit RISC MPU at 375 MHz paired with a C674x fixed‑ and floating‑point VLIW DSP core for signal processing tasks.
• Memory and Caches  Multi‑level on‑chip memory including ARM caches and DSP RAM: examples in the series include 16KB instruction and 16KB data caches, 32KB L1 program/data RAM for DSP, and 256KB L2 unified mapped RAM/cache plus 128KB shared RAM.
• High‑speed I/O and Storage  Integrated interfaces include 10/100 Mbps Ethernet, SATA 3 Gbps, USB 1.1 and USB 2.0 with PHYs, and an LCD display controller for system and user‑interface connectivity.
• External Memory Support  Two external memory interfaces: EMIFA for NOR/NAND and support for 16‑bit SDRAM, plus a DDR2/Mobile DDR memory controller supporting expanded address spaces.
• DMA and System Peripherals  Enhanced EDMA3 controller with extensive channel support (including 64 independent DMA channels and 16 QDMA channels) for high‑throughput data movement and low CPU overhead.
• Security  On‑chip security features for boot security and cryptography to support secure system boot and data protection.
• Packaging and Mounting  361‑NFBGA (16×16) surface‑mount package optimized for high‑density board designs.

Typical Applications

• Industrial Control & Automation  Real‑time control and signal processing using the combined ARM and C674x DSP resources, with Ethernet connectivity for networked systems.
• Multimedia & Imaging Appliances  DSP acceleration for audio, imaging and other signal‑processing pipelines alongside an ARM application processor for system control and HMI tasks with the LCD controller.
• Storage and Data Recording  Integrated SATA 3 Gbps and USB interfaces enable local mass‑storage, logging and data‑acquisition systems requiring sustained throughput.
• Communication Gateways  Ethernet and USB connectivity combined with DSP processing make the device suitable for protocol processing, packet handling and edge compute nodes.

Unique Advantages

• Integrated ARM + DSP Processing:  Combines a 375 MHz ARM926EJ‑S MPU with a C674x DSP core to consolidate application control and heavy signal processing in a single device, reducing BOM and board complexity.
• Comprehensive I/O Suite:  On‑chip Ethernet, SATA, USB 1.1/2.0 with PHYs and LCD controller provide direct connectivity for networking, storage and user interfaces without multiple external controllers.
• High‑performance Data Movement:  EDMA3 with dozens of DMA and QDMA channels offloads copy and transfer work from processors, enabling efficient real‑time data paths.
• Flexible Memory Architecture:  Multiple cache and RAM levels plus external memory interfaces (EMIFA, SDRAM, DDR2/Mobile DDR) support a wide range of application memory footprints and performance profiles.
• Built‑in Security Features:  Boot security and cryptography capabilities help protect system integrity and sensitive data at power‑up and runtime.
• Software and Library Support:  Series documentation indicates availability of TI DSP/BIOS and DSP libraries to accelerate development and algorithm deployment.
