Procurement Notes
This component is classified as End-of-Life (EOL) by the manufacturer. A Product Discontinuation Notification was issued on May 24, 2018. Availability is restricted, and Mouser Electronics indicates that the product is not currently sold in certain regions. Verification of current stock status and alternative sourcing strategies is required before procurement planning.
Selection Notes
Designers should consider the EOL status when selecting this component for new products. The QFN-28 package requires appropriate surface mount assembly processes. Ensure that the system design accommodates the specified 2.7 V to 3.6 V supply voltage range and the -40°C to +85°C operating temperature limits. Verify compatibility with existing serial interface logic levels.
Part Context
The BU8772KN-E2 belongs to the BU8772KN series of telecom interface ICs from ROHM Semiconductor. It is categorized under Telecom Sound Generators and Interface ICs. This specific part number represents a discontinued variant within the family, originally intended for integration into mobile communication devices requiring dedicated audio tone generation hardware.
Replacement Considerations
As an End-of-Life product, direct substitutes are not explicitly listed in available public documentation. Engineers must evaluate functional equivalents from other manufacturers or newer generations of ROHM sound generators that maintain compatible pinouts and electrical characteristics.
