XOMAPL138ZCE

Overview

The Texas Instruments OMAPL138ZCE is a dual-core system-on-chip integrating an ARM926EJ-S RISC processor and a C674x fixed/floating-point VLIW DSP. It operates at frequencies up to 456 MHz with core voltages of 1.2V or 1.3V. The device features 16KB instruction and data caches on the ARM side, alongside 32KB L1P, 32KB L1D, and 256KB L2 memory for the DSP. It includes 128KB shared RAM, SATA, USB 2.0 OTG, Ethernet MAC, and PRU subsystems within a 361-ball NFBGA package measuring 13mm x 13mm.

Feature Summary

• Dual-core architecture combining ARM926EJ-S and C674x DSP cores
• Integrated Serial ATA controller supporting SATA I and II standards
• Programmable Real-Time Unit subsystem with two independent PRU cores
• Hardware-based secure boot flow utilizing AES-128 encryption

Applications

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

Procurement Notes

Verify the specific frequency grade required for your design, as the ZCE package supports both 375 MHz and 456 MHz variants distinguished by operating voltage. Confirm that the 13mm x 13mm NFBGA footprint matches your PCB layout constraints. Ensure compliance with RoHS directives and check for any export control restrictions applicable to this component in your region.

Selection Notes

Select the OMAPL138ZCE when a mixed-signal processing solution is needed for applications requiring real-time DSP performance alongside robust OS support. This part is suitable for designs needing integrated high-speed storage interfaces like SATA and programmable real-time capabilities via the PRUSS without external controllers.

Part Context

The OMAPL138ZCE belongs to the OMAP-L138 family, designed for low-power embedded applications. It utilizes a 361-ball NFBGA package with a 0.65mm pitch. The device is part of the TMS320C6000 platform, offering code compatibility with other C674x devices while providing enhanced connectivity through integrated peripherals like Ethernet and USB.
