BU97981KV-BZE2

Display Drivers Overview

The BU97981KV-BZE2 is an LCD segment driver manufactured by ROHM Semiconductor, designed for driving displays with up to 196 segments. It operates within a supply voltage range of 1.8 V to 3.6 V and supports a maximum clock frequency of 4 MHz. The device features a 3-wire serial interface and is housed in a 64-pin VQFP package (VQFP-64). It has a maximum power dissipation of 1 W and a maximum supply current of 130 uA. The component functions reliably across an operating temperature range from -30°C to +75°C.

Display Drivers Feature Summary

• Supports driving up to 196 LCD segments via a 3-wire serial interface
• Operates on low voltage supplies ranging from 1.8 V to 3.6 V
• Integrated into a compact 64-pin VQFP surface-mount package

Display Drivers Applications

• Segmented LCD display drivers
• Low-power electronic instrumentation panels
• Consumer appliance control interfaces

Display Drivers Procurement Notes

Verify the specific suffix 'BZE2' against the official ROHM datasheet to confirm pinout compatibility and electrical characteristics relative to other variants in the BU97981 series. Ensure that the 64-VQFP package dimensions match the target PCB footprint. Confirm RoHS compliance status and moisture sensitivity level requirements for the intended manufacturing process.

Display Drivers Selection Notes

Select this component when a low-voltage, single-supply LCD driver is required for applications with limited segment counts up to 196. The 3-wire interface minimizes microcontroller I/O usage. Consider the thermal performance given the 1 W power dissipation limit and the -30°C to +75°C operating range. Verify that the 4 MHz maximum clock speed meets the refresh rate requirements of the display system.

Display Drivers Part Context

This part belongs to the BU97981KV series of LCD drivers from ROHM Semiconductor. It is functionally similar to the BU97981KV-E2 but may differ in packaging or specific ordering suffixes. The series is categorized under Display Drivers and PMICs, targeting cost-effective solutions for simple segmented LCD applications requiring minimal external components.

Display Drivers Replacement Considerations

The BU97981KV-E2 is listed as an alias or variant within the same product family. Verify if the 'BZE2' suffix denotes a specific tape-and-reel configuration or environmental rating compared to the standard 'E2' version before substitution.
