NSP2340BA24E

The NSP2340BA24E Smart Buzzer is a highly integrated voice IC optimized for modern embedded systems that require reliable audio feedback with minimal system overhead. By integrating voice storage, control logic, and high-voltage piezo driving capability into a single device, NSP2340BA24E Smart Buzzer enables efficient system design and a consistent user experience across a wide range of applications.

Designed to simplify system architecture, NSP2340BA24E Smart Buzzer integrates embedded Flash memory for standalone voice and sound playback, eliminating the need for external memory devices. Flexible host interfaces, including UART, I²C (slave), and Two-Wire interface, allow seamless integration with various microcontrollers and system platforms.

The integrated voltage booster and Class-AB output stage provide selectable high-voltage outputs up to 24 V, allowing direct drive of piezo buzzers without external high-voltage components. This architecture reduces BOM cost, PCB area, and design complexity while maintaining strong acoustic performance.

With ultra-low standby current, automatic power management, and built-in protection mechanisms, NSP2340BA24E Smart Buzzer is designed to meet the reliability and power efficiency requirements of consumer, industrial, and medical systems.
