Description and Introduction

Single-Chip Voice Record/Playback Devices 32-, 40-, 48-, 64-,60-,75,90-, and 120-Second Durations The ISD2575SI is a voice record and playback chip manufactured by ISD (Integrated Silicon Solution Inc.). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage:** 3V (typical)  
- **Operating Current:** 25mA (typical during playback/record)  
- **Standby Current:** 1μA (typical)  
- **Sampling Frequency:** 8kHz  
- **Recording Time:** 75 seconds (depends on sampling rate)  
- **Storage Method:** Non-volatile flash memory (no battery backup required)  
- **Interface:** Serial (SPI-compatible)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 28-pin SOIC  

### **Descriptions:**  
- The ISD2575SI is a single-chip voice recording and playback solution with non-volatile storage.  
- It eliminates the need for external memory or compression algorithms.  
- Supports direct analog storage, providing high-quality audio output.  

### **Features:**  
- **Single-Chip Solution:** No external components needed for basic operation.  
- **Non-Volatile Storage:** Retains data without power.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Multiple Playback Modes:** Supports random access and sequential playback.  
- **Microcontroller Interface:** SPI-compatible serial control.  
- **High-Quality Audio:** No compression artifacts due to direct analog storage.  
- **Durable Flash Memory:** Supports 100,000 record/erase cycles.  

This information is based solely on the manufacturer's datasheet and technical documentation.
