L138-FI-325-RC

Overview

The Critical Link L138-FI-325-RC is a System-on-Module based on the Texas Instruments OMAP-L138 processor and Xilinx Spartan-6 FPGA. It features a dual-core architecture with a 456 MHz ARM926EJ-S MPU and a 456 MHz TMS320C674x DSP core. The module integrates an XC6SLX45 FPGA, up to 256 MB of mDDR2 RAM, 16 MB of SPI NOR flash, and 128 MB of NAND flash. It utilizes a standard SO-DIMM-200 interface for connectivity, supporting interfaces such as Ethernet, USB, UART, and SATA (optional).

Procurement Notes

Verify the specific memory and FPGA configuration against the datasheet Table 5. Confirm if optional features like SATA support or the JTAG debug header are required, as these are not included in the standard model configuration. Contact the manufacturer for current shipping status and availability details.

Selection Notes

Select this module for applications requiring high-performance digital signal processing combined with programmable logic. Ensure carrier board design supports the SO-DIMM-200 interface and provides the necessary 3.3V power supply. Consider the industrial temperature range options if operation outside the commercial 0°C to 70°C range is needed.

Part Context

This part belongs to the MityDSP-L138F family of System-on-Modules from Critical Link. It is designed to provide a flexible embedded processing platform by combining TI's OMAP-L138 application processor with Xilinx FPGA technology in a compact, industry-standard form factor.

Replacement Considerations
