L138-FG-326-RC

Overview

The Critical Link L138-FG-326-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, integrated with up to 256 MB mDDR2 RAM, 16 MB SPI NOR Flash, and 256 MB Parallel NAND Flash. The module utilizes a standard SO-DIMM-200 interface, providing 96 configurable FPGA I/O pins alongside multiple communication interfaces including Ethernet, USB, UART, and MMC/SD. Designed for commercial temperatures (0°C to 70°C), it supports fixed and floating-point operations within a single CPU architecture.

Procurement Notes

Verify specific configuration requirements such as SATA support or JTAG headers, as these are optional codes not included in the standard model. Confirm availability through Critical Link distribution partners, as stock levels may vary. Ensure carrier board design accommodates the SO-DIMM-200 form factor and provides appropriate power regulation for the 3.3V input requirement.

Selection Notes

Select this model for applications requiring high-performance digital signal processing combined with programmable logic in a compact form factor. The 456 MHz clock speed supports complex real-time algorithms. Consider the industrial temperature variant if operation below 0°C is required. Verify that the 256 MB NAND capacity meets persistent storage needs for root file systems and application data.
