Overview

The OMAPL138EZWTA3 is a dual-core applications processor that integrates a 375MHz ARM926EJ-S RISC core with a C674x fixed/floating-point DSP. This architecture allows developers to offload complex signal processing tasks to the DSP while maintaining system control and user interface functions on the ARM core. It features integrated SATA 3Gbps and 10/100 Ethernet, making it suitable for high-speed data connectivity in embedded systems.

Why Choose This Part

The heterogeneous architecture provides a power-efficient balance between high-performance signal processing and general-purpose OS support. Its integrated high-speed peripherals, including SATA and USB 2.0 with PHY, reduce total system bill-of-materials and PCB footprint compared to multi-chip solutions.

Applications

Industrial Software-Defined Radio
Utilizing the C674x DSP for real-time waveform processing while the ARM core manages the networking stack and user interface.
Power Protection Relays
Performing fast Fourier transforms (FFT) on power line samples for fault detection and monitoring.
Networked Audio Processing
Handling multi-channel audio effects and filtering on the DSP with 10/100 Ethernet streaming support.
Portable Data Concentrators
Managing high-speed local storage via SATA and diverse peripherals for industrial sensor data logging.

Getting Started

Developers typically use the Texas Instruments Code Composer Studio (CCS) IDE and the Processor SDK, which includes Linux and RTOS support. Hardware evaluation can be performed using the OMAP-L138 LCDK (Low Cost Development Kit) or specialized System-on-Modules (SoMs). Ensure proper power sequencing for the multiple voltage rails as specified in the datasheet to prevent long-term reliability issues.
