NSP2340A03G Function Demonstration

NSP2340A03G is a cost-effective, high-quality voice playback chip with built-in Flash. It contains an I2C, UART, or GPIO interface for communicating with external microcontroller chips.

NSP2340A03G has high-quality voice output and an output power of up to 3 watts. It can drive speakers directly and is suitable for various voice prompt applications. In addition, an NSP development board is provided, with easy-to-use sound combination software tools, which can quickly complete voice programming and demonstration functions, greatly shortening the development program time.

NSP2340A03G's application scope covers electronic medical equipment, home appliances, cleaning supplies, kitchen cooking, security equipment, smart door locks, elevator systems, control panels, charging piles, and more.
