XOMAPL138ZWT

Overview

The Texas Instruments OMAPL138ZWT is a dual-core application processor featuring an ARM926EJ-S RISC MPU and a C674x DSP. It operates at frequencies up to 456 MHz with a 1.3V core voltage or 375 MHz at 1.2V. The device integrates 32KB L1P, 32KB L1D, and 256KB L2 cache for the DSP, alongside 16KB I-Cache and 16KB D-Cache for the ARM core. It includes 128KB shared RAM, USB 2.0 OTG, SATA, EMAC, and uPP interfaces. The component is housed in a 361-ball NFBGA package measuring 16.00 mm x 16.00 mm.

Feature Summary

• Dual-core architecture combining ARM926EJ-S and C674x DSP for mixed processing tasks
• Integrated security features including Basic Secure Boot with AES-128 encryption
• High-speed connectivity via Serial ATA (SATA) and Universal Parallel Port (uPP)
• Programmable Real-Time Unit Subsystem (PRUSS) for deterministic control

Applications

• Industrial Automation
• Remote Radio Unit (RRU)
• Machine Vision (Low-End)

Procurement Notes

Verify the specific frequency grade required for your design, as the ZWT package supports both 375 MHz and 456 MHz variants distinguished by core voltage requirements. Confirm that the 16mm x 16mm NFBGA footprint matches your PCB layout constraints. Ensure thermal management solutions are adequate for the specified operating junction temperature range.

Selection Notes

Select this model when a 16mm x 16mm package is necessary compared to the smaller 13mm variant. Consider the 456 MHz speed grade if higher computational throughput is needed, noting the increased power consumption associated with the 1.3V core voltage requirement versus the 1.2V option.

Part Context

This part belongs to the OMAP-L138 family, designed for low-power applications requiring robust DSP capabilities alongside a standard RISC processor. It serves as a system-on-chip solution for embedded systems needing real-time signal processing and complex OS support simultaneously.

Replacement Considerations

OMAPL138ZCE is the primary alternative within the same family, offering identical functionality but in a smaller 13mm x 13mm package.
