Display Drivers Procurement Notes

Verify the specific suffix E2 against official ROHM documentation to confirm compliance status and revision details. Confirm the VQFN-56 package dimensions match your PCB footprint requirements. Ensure the 3-Wire interface timing aligns with your host controller specifications before finalizing procurement.

Display Drivers Selection Notes

Select this component when designing systems requiring drive for up to 168 LCD segments using a 3-Wire interface. It is suitable for applications needing operation within a 1.8 V to 3.6 V supply range. Consider the VQFN-56 package size and thermal dissipation capabilities relative to your board layout constraints.

Display Drivers Part Context

This part belongs to the BU97981MUV series of LCD drivers manufactured by ROHM Semiconductor. It shares functional similarities with other members like the BU97981KV-E2 but differs in package type and segment capacity. The series targets general-purpose segment LCD applications requiring efficient serial control.

Display Drivers Replacement Considerations

The BU97981KV-E2 serves as a related alternative within the same family, offering 196 segments in a VQFP-64 package. Verify pin compatibility and segment count differences before substitution.
