Memory IC Procurement Notes

Verify the specific ordering suffix 'IGR' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Confirm that the 1.65V-2.0V voltage range aligns with your system's power supply design. Check for any end-of-life or not-recommended-for-new-designations in official distributor catalogs before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 256M-bit capacity is required with low-voltage operation between 1.65V and 2.0V. It is suitable for designs needing high-speed interface options including DTR Quad I/O for maximum throughput. Ensure the application can accommodate the WSON8 or WLCSP package options provided. Consider the software-based write protection if data integrity during updates is critical.
