Display Drivers Procurement Notes

Verify the current lifecycle status before procurement, as this component is marked as NRND (Not Recommended for New Designs). Confirm package authenticity and check for moisture sensitivity handling requirements during storage and assembly. Ensure compatibility with existing 3-wire control logic and voltage levels.

Display Drivers Selection Notes

Select this driver when a compact BGA footprint is required for high-segment-count LCDs. It is suitable for designs needing 3-wire simplicity rather than I2C. Consider the NRND status for long-term production viability and evaluate alternative models if new design introduction is planned.

Display Drivers Part Context

This part belongs to the BU9795AGUW series of LCD drivers from ROHM. It is distinct from other family members like the BU9795ZKS2-E2 or BU97950AFUV-E2 due to its specific segment count, package type, and interface protocol.
