Nuvoton Technology has introduced the NSP2340BA24E smart buzzer IC, which enables conventional piezo buzzers to play voice messages, melodies and sound effects instead of simple beeps. The single-chip solution integrates audio storage, buzzer driving, voltage boosting and amplification for clearer device alerts and status notifications.
Nuvoton NSP2340BA24E smart buzzer chip
Key Characteristics
- Function: Converts standard piezo buzzers into voice/melody/sound-effect players
- Integrated blocks:
- Embedded Flash memory for audio storage
- Buzzer driver
- Voltage booster (up to 24 V output)
- Class-AB amplifier
- Booster output: up to 24 V
- Host interfaces: UART, I²C and Two-Wire
- Programming: In-System Programming (ISP) — audio content can be updated via host MCU
- Direct drive of piezo buzzers
- Allows custom voice messages and sound effects for product differentiation
By combining storage, boost, drive and amplification in one IC, the NSP2340BA24E turns a simple buzzer into an intelligent audio interface that communicates operating status, warnings and notifications more clearly than traditional beep patterns.
Target Applications
- Home appliances (operation and completion notifications)
- Security systems (warning alerts)
- Industrial equipment (status indication)
- Healthcare devices
- Other smart products requiring clear audible feedback
