OMAPL138AZCEA3

Microprocessors Overview

The OMAPL138AZCEA3 is a dual-core system-on-chip integrating an ARM926EJ-S RISC processor and a C674x fixed/floating-point VLIW DSP. Operating at 375 MHz with a 1.2V core voltage, it utilizes a 361-ball PBGA package with a 0.65mm pitch (ZCE). The architecture includes 16KB instruction and data caches for the ARM core, alongside 32KB L1P, 32KB L1D, and 256KB L2 cache for the DSP. It features 128KB of shared RAM, USB 2.0 OTG, SATA, Ethernet MAC, and PRU subsystems.

Microprocessors Feature Summary

• Dual-core heterogeneous architecture combining ARM926EJ-S control capabilities with C674x high-performance digital signal processing.
• Integrated Programmable Real-Time Unit (PRU) subsystem providing deterministic real-time control capabilities.
• Comprehensive peripheral set including SATA, Ethernet, USB, and video interfaces for multimedia and industrial applications.
• Hardware-based secure boot functionality to protect intellectual property and ensure trusted code execution.

Microprocessors Applications

• Remote Radio Units (RRU) and Remote Radio Heads (RRH)
• Industrial Automation systems
• Professional or Private Mobile Radio (PMR)
• Smart Grid Substation Protection

Microprocessors Procurement Notes

Verify the specific speed grade and package variant against project requirements. Confirm that the 375 MHz performance level meets application timing constraints. Ensure the 0.65mm pitch BGA footprint aligns with PCB design capabilities. Check for any specific revision errata relevant to the manufacturing date code.

Microprocessors Selection Notes

Select this component when a balance of general-purpose processing and high-throughput algorithmic execution is required. The 375 MHz variant offers lower power consumption compared to the 456 MHz version. Consider the ZCE package dimensions if board space is limited. Evaluate the need for the PRU subsystem for deterministic tasks versus standard timer peripherals.

Microprocessors Part Context

This device belongs to the Texas Instruments OMAP-L138 family, designed as a low-power applications processor. It targets OEMs and ODMs needing robust operating systems and rich user interfaces. The platform supports both fixed-point and floating-point operations within the DSP core, enabling efficient implementation of complex algorithms in embedded environments.

Microprocessors Replacement Considerations

OMAPL138BZCED4E: Offers 456 MHz performance but requires 1.3V core voltage and has a different I/O voltage range.
