Procurement Notes
Verify that the specific configuration matches the required memory sizes and temperature rating. The standard model does not include SATA support or the JTAG debug header; these are available as optional order codes. Confirm compatibility with carrier boards using the SO-DIMM-200 interface specifications provided in the datasheet.
Selection Notes
Select this module for applications requiring high-performance digital signal processing alongside general-purpose computing. Ensure the carrier board supports the 3.3V power supply requirement. Consider option codes if SATA connectivity or JTAG debugging capabilities are necessary for the development process.
Part Context
This part belongs to the MityDSP-L138 family from Critical Link. It is designed to accelerate embedded product development by providing a pre-integrated processor card. The module leverages the OMAP-L138's ability to run Linux and other OSs on the ARM core while handling real-time tasks on the DSP core.
Replacement Considerations
No direct public substitute part numbers are listed in the source material. For upgrades, consider other models in the MityDSP-L138 series with different memory configurations or industrial temperature ratings, such as the L138-DX-325-RI.
