Procurement Notes

Verify the specific ordering suffix 'RI' confirms the industrial temperature range (-40°C to 85°C) and the 375 MHz speed grade as listed in the official Critical Link datasheet. Confirm current production status and availability directly with the manufacturer or authorized distributors, as lead times may vary.

Selection Notes

Select this model for applications requiring an ARM9 processor combined with FPGA programmability in an industrial environment. Ensure carrier board design supports the SO-DIMM-200 form factor and provides the required 3.3V power supply. Verify that the 375 MHz processing speed meets performance requirements compared to the higher-speed commercial variants.

Part Context

This part belongs to the MitySOM-1808F family, which integrates the TI AM1808 processor with Xilinx Spartan-6 FPGAs. The 1808-DG-225-RI variant specifically denotes the industrial temperature rating and the lower clock speed configuration within the product line.

Replacement Considerations

Direct replacements are not explicitly listed in the provided documentation. Consider evaluating other MitySOM-1808F variants for different speed grades or memory configurations, or consult Critical Link for updated successor modules.
