L138-FG-325-RC

Overview

The Critical Link L138-FG-325-RC is a System-on-Module based on the Texas Instruments OMAP-L138 processor and Xilinx Spartan-6 FPGA. It features a 456 MHz ARM926EJ-S MPU and a 456 MHz C674x VLIW DSP core. The module includes up to 128 MB of mDDR2 RAM, 16 MB of SPI NOR Flash, and 256 MB of Parallel NAND Flash. It utilizes a standard SO-DIMM-200 interface with 96 configurable FPGA I/O pins. Operating temperature range is commercial (0°C to 70°C).

Feature Summary

• Dual-core OMAP-L138 processor with 456 MHz ARM926EJ-S and C674x DSP cores.
• Integrated Xilinx Spartan-6 XC6SLX16 FPGA with up to 2,088 KBits Block RAM.
• Memory configuration: 128 MB mDDR2, 16 MB SPI NOR Flash, 256 MB NAND Flash.
• SO-DIMM-200 form factor with 96 user-accessible FPGA I/O pins.

Applications

• Software Defined Radio
• Industrial Automation
• Embedded Instrumentation
• Medical Instrumentation

Procurement Notes

Verify the specific memory capacities and FPGA model against the ordering table in the datasheet. Confirm that SATA support and JTAG headers are not included in the standard configuration and require option codes if needed. Check for industrial temperature variants if operation outside 0°C to 70°C is required.

Selection Notes

Select this module for applications requiring simultaneous ARM control and DSP processing alongside programmable logic. Ensure carrier board design supports the SO-DIMM-200 connector and provides the necessary 3.3V power supply. Consider the 6SLX16 FPGA size limits for complex logic designs compared to the 6SLX45 options.

Part Context

This part belongs to the MityDSP-L138F family of System-on-Modules from Critical Link. It is designed as a compact, highly configurable processor card integrating TI's OMAP-L138 with Xilinx FPGA technology for embedded digital signal processing infrastructure.

Replacement Considerations

For industrial temperature requirements (-40°C to 85°C), consider the L138-DG-325-RI variant which shares similar specifications but operates in a wider temperature range.
