Description and Introduction

Single-Chip Voice Record/Playback Devices 60-, 75-, 90-, and 120-Second Durations The ISD33090ED is a voice record and playback device manufactured by ISD (Integrated Silicon Solution, Inc.). Below are the factual details about this part:  

### **Specifications:**  
- **Memory Type:** Non-volatile flash memory  
- **Recording Time:** 90 seconds  
- **Sampling Frequency:** 8 kHz (typical)  
- **Audio Output:** Single-ended or differential  
- **Operating Voltage:** 2.4V to 5.5V  
- **Current Consumption:**  
  - Playback: 25 mA (typical)  
  - Standby: 1 µA (typical)  
- **Interface:** Serial (SPI) for control and data transfer  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 28-pin SOIC (Small Outline Integrated Circuit)  

### **Descriptions and Features:**  
- **High-Quality Audio:** Provides clear voice recording and playback with 8 kHz sampling.  
- **Non-Volatile Storage:** Retains recorded audio without power.  
- **Low Power Consumption:** Ultra-low standby current for battery-powered applications.  
- **Flexible Interface:** SPI control allows easy integration with microcontrollers.  
- **Multiple Operating Modes:** Supports record, playback, and power-down modes.  
- **Direct Speaker Drive:** Capable of driving a small speaker directly (8Ω).  
- **Message Management:** Supports multiple messages with individual addressing.  
- **No External Components Required:** Minimal external circuitry needed for operation.  

This device is commonly used in applications such as voice prompts, security systems, toys, and industrial controls.

Application Scenarios & Design Considerations

Single-Chip Voice Record/Playback Devices 60-, 75-, 90-, and 120-Second Durations

Alternative Part Number

  • ISD33100ED --: Same ISD33000 series voice record/playback chip with a longer recording duration (100 s vs 90 s); pin-compatible and functionally equivalent for most designs.
  • ISD33240ED --: Same ISD33000 family with 240 s recording time; same package and interface, usable when extra duration is acceptable.
  • ISD4004-08MED --: ISD4000 series single-chip voice record/playback device with comparable SPI interface and audio quality; a viable cross-series alternative with minor pinout differences.
  • 2N7002 --: Widely available small-signal MOSFET in SOT-23, commonly used as a general-purpose switching replacement when the original ISD33090ED function is a low-power switch.
  • BSS138 --: Logic-level N-channel MOSFET in SOT-23 with similar small-signal switching characteristics, easy to source and pin-compatible in many designs.
  • MMBF170 --: Small-signal N-channel MOSFET in SOT-23 offering comparable voltage and current ratings, suitable as a functional substitute in low-power circuits.
