ISD2540P Description

Short technical summary and product information.

The Nuvoton ISD2540P is a highly integrated, single-chip voice record and playback solution designed for messaging applications. It provides 40 seconds of recording and playback duration, storing voice and audio signals directly into non-volatile memory for zero-power message retention.

 

Key electrical characteristics include a wide operating voltage range of 4.5V to 6.5V and a sampling frequency of 6.4kHz with a filter pass band of 2.7kHz. The device features Automatic Gain Control (AGC) for consistent audio input levels and offers both internal and external oscillator options. The output signal is a PWM speaker output, suitable for direct drive.

 

Designed for ease of use, the ISD2540P is microcontroller compatible and supports multiple messages. It can be edge- or level-activated for playback and is directly cascadable for longer durations. The device operates within a temperature range of 0°C to 70°C (TA) and is available in a 28-DIP (0.600", 15.24mm) package, mounted via through-hole.

 

This device is ideal for applications requiring simple, solid-state voice recording and playback, such as automated announcements, voice prompts, and message storage systems.
