Procurement Notes
Verify the specific revision suffix against official Critical Link documentation to confirm pinout compatibility and supported OS versions. Confirm current availability status as product lifecycles may vary. Ensure the host carrier board supports the SO-DIMM-204 interface electrical specifications required for this MPU module.
Selection Notes
Select this module when an ARM Cortex-A9 architecture is required for deterministic real-time performance in embedded environments. Compare the 800 MHz processing speed and 512 MB RAM limits against application workload requirements. Verify that the 0°C to 70°C commercial/industrial temperature rating meets the deployment site conditions.
Part Context
This part number belongs to the Critical Link MitySOM series, which focuses on System-on-Module solutions based on Texas Instruments OMAP processors. The 1808 designation typically refers to the OMAP-L138 processor variant. This module serves as a complete computing solution, integrating the processor, memory, and boot flash into a standardized footprint for easy integration into custom carrier designs.
Replacement Considerations
Check Critical Link's official transition notices for successor modules within the MitySOM family. Verify if newer revisions maintain binary compatibility with existing carrier boards and software drivers before substituting.
