ISD1110P

The Nuvoton Technology ISD1110P is a single-chip voice record and playback device designed for messaging applications requiring up to 10 seconds of duration. This CMOS device integrates essential components like an on-chip oscillator, microphone preamplifier, automatic gain control (AGC), and speaker amplifier, simplifying system design.

Key electrical specifications include a single 5-volt power supply requirement (4.5V to 5.5V), a sampling frequency of 6.4kHz, and a filter pass band of 2.6kHz. The device supports pushbutton interface for playback control and offers multiple messaging capabilities. It operates within a commercial temperature range of 0°C to 70°C.

Recordings are stored in on-chip non-volatile memory cells, providing zero-power message storage. The ISD1110P is available in a 28-DIP package suitable for through-hole mounting. Its features include high-quality, natural voice reproduction and automatic power-down to a low standby current of 0.5 µA typical.

This IC is ideal for applications needing simple, solid-state voice recording and playback, such as interactive toys, voice memos, or simple alert systems. The integrated AGC ensures consistent recording levels, while the internal oscillator eliminates the need for external clock components.
