BU9716BKV

Display Drivers Overview

The BU9716BKV is a highly integrated LCD segment driver IC manufactured by ROHM Semiconductor. It supports up to 96 segments and operates within a supply voltage range of 4.5V to 5.5V. The device features a 3-wire serial interface for data transmission and is housed in a 48-pin VQFP package. It is designed for low-duty LCD applications, such as STN displays, with an operating temperature range spanning from -40°C to +85°C.

Display Drivers Feature Summary

• Highly integrated design for driving STN LCD segments
• Supports 3-wire serial communication interface
• Optimized for low power consumption in portable devices

Display Drivers Applications

• STN LCD panel drivers
• Portable electronic devices requiring segment display control
• Industrial instrumentation displays

Display Drivers Procurement Notes

Verify the specific suffix 'E2' or other variants if exact compliance with RoHS or automotive standards is required, as the base part number may have multiple revisions. Confirm package tolerance and moisture sensitivity level (MSL) against your assembly process requirements. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability.

Display Drivers Selection Notes

Select this component when a compact solution for driving up to 96 LCD segments is needed. It is suitable for systems operating at standard 5V logic levels. Consider the 48-pin VQFP footprint for PCB layout constraints. Verify that the 3-wire interface matches the host microcontroller's available pins and protocol support.

Display Drivers Part Context

This part belongs to the BU9716 series of LCD drivers from ROHM. These drivers are commonly used in applications requiring simple interface protocols and moderate segment counts. The series is known for integrating necessary drive circuits into a single small package, reducing external component count compared to discrete solutions.

Display Drivers Replacement Considerations

Check for direct substitutes within the BU9716 series or compatible pin-to-pin replacements from other manufacturers. Ensure electrical parameters such as supply voltage and segment capacity match. Verify interface compatibility before substitution.
