Memory IC Procurement Notes

Verify the specific suffix 'BB' corresponds to the 16-ball WLCSP package and lead-free RoHS compliance. Confirm that the ordering information matches the required dummy cycle configurations and voltage specifications. Ensure compatibility with the intended SPI controller interface regarding mode 0 and mode 3 support.

Memory IC Selection Notes

Select this component when a low-voltage 1.8V operation is required for space-constrained designs. The 16-ball WLCSP package offers a compact footprint suitable for mobile or portable electronics. Consider the DTR mode if higher data throughput is necessary without increasing the clock frequency significantly.
