Memory IC Procurement Notes

Verify the End-of-Life status before procurement, as discontinuation notices indicate potential obsolescence. Confirm RoHS compliance details through official documentation. Ensure compatibility with existing board layouts due to the specific SOJ-36 package dimensions. Check for moisture sensitivity handling requirements during storage and assembly processes.

Memory IC Selection Notes

Select this component when a 512k x 8 SRAM configuration with 12 ns speed is required. Consider the SOJ-36 package constraints for PCB design. Evaluate the 0°C to +70°C commercial temperature range against environmental conditions. Compare power consumption specifications with alternative memory solutions if efficiency is critical.
