Memory IC Procurement Notes

Verify the specific suffix 'TL' against the official datasheet to confirm package type and temperature range. Ensure the ordering information matches the manufacturer's current production status. Confirm that the SSTL_2 interface requirements are compatible with the target system design before procurement.

Memory IC Selection Notes

Select this component for applications requiring high-speed data transfer in mobile environments. Consider the 66-pin TSOP II package constraints for PCB layout. Evaluate power consumption characteristics against system battery life requirements. Verify compatibility with the host controller's DDR memory interface specifications.

Memory IC Part Context

This part belongs to the IS43R83200B series of 256Mb DDR SDRAMs from ISSI. It shares architectural similarities with other parts in the family but differs in speed grade and packaging. The -5 speed grade indicates a 200 MHz capability. The series is designed for portable electronic devices requiring compact memory solutions.

Memory IC Replacement Considerations

Check for equivalent parts from ISSI within the same 256Mb DDR SDRAM lineup. Verify pinout compatibility and electrical specifications. Consider alternative manufacturers offering similar SSTL_2 interface DRAMs if supply constraints exist.
