Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates reel packaging when ordering. Confirm the 1.2V nominal voltage requirement aligns with your system's power rails, as the device operates between 1.14V and 1.6V. Ensure compatibility with the WLCSP-12 package dimensions during PCB layout. Check current availability status as supply may be restricted.

Memory IC Selection Notes

Select this component when a balance of moderate storage capacity and ultra-low profile is required. It is appropriate for designs where board space is critical and power efficiency is prioritized over high-speed performance. Consider the 120 MHz limit if higher throughput is needed. Verify that the 1.2V logic level matches your processor's I/O standards.

Memory IC Part Context

This part belongs to the MX25S series, which targets low-voltage applications compared to the MX25L series. It shares the 64Mbit density with other variants but differs in package type and voltage specifications. The FBBI42 suffix denotes the specific WLCSP-12 package configuration and trailing zero designation.
