Display Drivers Procurement Notes
Verify the lifecycle status before procurement, as this component is marked as NRND (Not Recommended for New Designs). Confirm that the SSOP-A-32 package aligns with existing PCB footprints. Ensure compatibility with the 2.5V to 5.5V supply voltage requirements. Check for alternative sources if long-term availability is critical due to the end-of-life designation.
Display Drivers Selection Notes
Select this component for designs requiring an 80-segment LCD driver with I2C connectivity. It is suitable for applications needing low power consumption and internal RAM functionality. Consider the SSOP-A-32 package constraints during layout. Evaluate the NRND status against project longevity requirements. Compare against newer alternatives if new design inclusion is mandatory.
Display Drivers Part Context
This part belongs to the BU9796 series of LCD drivers from ROHM Semiconductor. It shares functional similarities with variants like the BU9796AFS-E2 and BU9796AMUV-E2, differing primarily in packaging and specific form factors. The series is characterized by low power operation and integrated memory capabilities for simplified system architecture.
