Display Drivers Procurement Notes

Verify component authenticity through authorized channels due to potential legacy status. Confirm RoHS compliance and MSL handling requirements prior to assembly. Review manufacturer documentation for any product change notices or end-of-life announcements that may affect long-term availability or supply chain stability.

Display Drivers Selection Notes

Select this component when a dedicated LCD driver with integrated key scanning is required. Ensure the design accommodates the SQFP-64 footprint and respects the 200 mW thermal dissipation limits. Verify compatibility with the target display's duty cycle and bias requirements against the datasheet specifications.

Display Drivers Part Context

This component belongs to the LC75857 series of LCD drivers. While originally developed under the Sanyo brand, the product line was acquired by onsemi. The WS-E suffix denotes the specific SQFP-64 package variant with enhanced moisture sensitivity handling characteristics compared to other package options in the family.
