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.

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
