Description and Introduction

SINGLE CHIP VOICE RECORD PLAYBACK DEVICE 4-, 5-, 6-, AND 8- MINUTE DURATIONS The ISD5008S is a single-chip voice record and playback device manufactured by Nuvoton (formerly ISD). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Duration:** 8 seconds (with a 6.4 kHz sampling rate).
- **Sampling Frequency:** Adjustable (6.4 kHz default).
- **Audio Output:** Single-ended or differential.
- **Supply Voltage:** 3V (2.4V to 5.5V operating range).
- **Standby Current:** 1 µA (typical).
- **Operating Current:** 25 mA (typical during playback/record).
- **Memory Type:** Non-volatile flash memory (no battery backup needed).
- **Interface:** SPI (Serial Peripheral Interface) for control.
- **Operating Temperature:** -40°C to +85°C.
- **Package:** 14-pin SOIC (Small Outline Integrated Circuit).

### **Descriptions:**
- The ISD5008S is a low-power, high-quality audio recording and playback IC.
- It integrates all necessary components (ADC, DAC, memory, and amplifier) into a single chip.
- Supports direct microphone input and speaker output without external components.
- Non-volatile storage retains recordings without power.

### **Features:**
- **Single-Chip Solution:** No external memory required.
- **Low Power Consumption:** Ideal for battery-powered applications.
- **High-Quality Audio:** 6.4 kHz sampling rate (adjustable for different durations).
- **Multiple Playback Modes:** Supports single or multiple message playback.
- **SPI Control:** Allows easy integration with microcontrollers.
- **Automatic Power-Down:** Reduces power consumption when idle.
- **Built-in Audio Processing:** Includes anti-aliasing and smoothing filters.
- **Endurance:** Supports at least 100,000 record/playback cycles.

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

Application Scenarios & Design Considerations

SINGLE CHIP VOICE RECORD PLAYBACK DEVICE 4-, 5-, 6-, AND 8- MINUTE DURATIONS

Alternative Part Number

  • ISD5116SY --: Same ISD single-chip voice record/playback family with similar SOIC package and SPI interface, offering comparable functionality as a drop-in style replacement.
  • ISD5216SY --: ISD5200 series voice record/playback IC with similar pinout and control interface, suitable when slightly different recording duration is acceptable.
  • ISD4004-08MSY --: ISD4004 series voice record/playback device with similar SPI control and audio quality, usable as a functional substitute with minor design adjustments.
  • ISD1760SY --: ISD1700 series voice record/playback chip with SPI interface and similar functionality; a practical substitute when the exact ISD5008S is unavailable, though pinout and duration differ.
  • AP8941 --: Alternative voice/message playback solution from a different vendor that can serve similar audio playback roles in designs where the original ISD part is obsolete.
