Description and Introduction

SINGLE-CHIP VOICE RECORD/PLAYBACK DEVICES 2-, 2.5-, 3-, AND 4-MINUTE DURATIONS The ISD33120PI is a voice record and playback chip manufactured by ISD (Integrated Silicon Solution Inc.).  

### **Specifications:**  
- **Model:** ISD33120PI  
- **Manufacturer:** ISD (Integrated Silicon Solution Inc.)  
- **Memory Type:** Non-volatile flash memory  
- **Recording Duration:** Up to 120 seconds (depends on sampling frequency)  
- **Sampling Frequencies:** Adjustable (typically 4 kHz to 12 kHz)  
- **Supply Voltage:** 2.4V to 5.5V  
- **Operating Current:** ~25 mA (typical during playback/record)  
- **Standby Current:** ~1 µA (typical)  
- **Interface:** Serial (SPI) or parallel control options  
- **Audio Output:** PWM or analog output (depends on configuration)  
- **Package:** 28-pin PDIP (Plastic Dual In-line Package)  

### **Descriptions and Features:**  
- **Single-Chip Solution:** Integrates recording, storage, and playback functions.  
- **Non-Volatile Storage:** Retains audio data without power.  
- **Direct Analog Storage:** No compression, providing high-quality audio.  
- **Multiple Sampling Rates:** Adjustable for different quality/duration trade-offs.  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Flexible Control Options:** Supports both serial (SPI) and parallel interfaces.  
- **Built-in Audio Processing:** Includes microphone preamp and speaker driver.  
- **Multistage Addressing:** Allows for segmented recording and playback.  
- **Automatic Power-Down:** Reduces power consumption when inactive.  

This chip is commonly used in applications like voice recorders, toys, security systems, and industrial voice prompts.

Application Scenarios & Design Considerations

SINGLE-CHIP VOICE RECORD/PLAYBACK DEVICES 2-, 2.5-, 3-, AND 4-MINUTE DURATIONS

Alternative Part Number

  • ISD33060PI --: Same ISD33000 series voice record/playback chip in the same DIP package with identical pinout, offering 60 seconds of recording instead of 120 seconds; a drop-in functional substitute when shorter duration is acceptable.
  • ISD2560P --: ISD2500 series single-chip voice record/playback device in a DIP package with similar control interface and audio output, widely used as a replacement for older ISD33000 parts in many designs.
  • ISD4004-08MP --: ISD4000 series SPI-controlled voice record/playback chip in DIP package; requires a microcontroller interface change but provides comparable audio quality and is a common migration path when ISD33000 parts are unavailable.
