Overview

The OMAPL138EZWT4 is a Texas Instruments DSP-plus-ARM processor that combines a C6000-class digital signal processor with an ARM core in a single device. It is aimed at designs that need both real-time signal processing and a general-purpose control processor. This kind of architecture is useful when one chip must handle deterministic DSP workloads and higher-level application code.

Why Choose This Part

This part is attractive when a design needs both hard real-time DSP capability and a flexible ARM control environment without splitting the job across two chips. That can simplify board design, reduce inter-processor communication overhead, and keep latency predictable for signal-processing tasks. It is especially useful in embedded systems that mix control, data acquisition, and communication software.

Applications

Industrial control gateways
Run protocol handling, control logic, and signal processing in one processor for compact industrial systems.
Motor control and drives
Use the DSP engine for fast control loops while the ARM side manages configuration, communications, and diagnostics.
Audio and voice processing
Handle filtering, echo reduction, and other real-time DSP tasks alongside system control software.
Embedded vision and sensor processing
Process streamed sensor data locally before forwarding results to another system or network.
Communications equipment
Support framing, modulation-related processing, and other compute-heavy signal tasks in embedded communications designs.

Getting Started

Start with a TI development kit or evaluation board for the OMAPL138 family so you can validate boot flow, peripherals, and DSP/ARM software partitioning before committing to hardware. Use the TI development tools and processor support packages appropriate for the device family, and verify the exact package, clocking, memory interface, and boot-media requirements against the TI documentation. For projects that rely on DSP workloads, plan early for memory bandwidth, real-time scheduling, and software toolchain integration between the DSP and ARM sides.
