Overview

The OMAPL138EZWTD4 is a dual-core applications processor that integrates a 456MHz ARM926EJ-S RISC core with a C674x fixed/floating-point DSP. This architecture allows developers to offload complex mathematical tasks and signal processing to the DSP while the ARM core handles system control, networking, and user interfaces.

Why Choose This Part

The primary advantage is the heterogeneous architecture which provides the deterministic performance of a DSP alongside the flexibility of an ARM microprocessor. It includes high-speed peripherals like SATA and USB 2.0 with integrated PHYs, reducing total PCB footprint and system cost.

Applications

Industrial Communications
Utilizing the integrated 10/100 Ethernet MAC and SATA 3Gbps interface for high-bandwidth industrial data logging and gateway applications.
Professional Audio Processing
Leveraging the C674x DSP for real-time audio filtering, equalization, and multi-channel effects in digital mixers.
Power Protection Systems
Using the DSP for high-speed analysis of power line harmonics while the ARM core manages SCADA communications.
Medical Instrumentation
Processing sensor data on the DSP and driving diagnostic displays via the integrated LCD controller.
