Professional IC Distribution & Technical Solutions

The ISD201 is an integrated circuit (IC) manufactured by ISOCOM, designed for voice recording and playback applications. Below are its key specifications, descriptions, and features:

Specifications:

• Supply Voltage: 4.5V to 6.5V (typically 5V)
• Operating Current: 25mA (typical during playback/record)
• Standby Current: <1µA (low power mode)
• Recording Time: Up to 20 seconds (depends on sampling rate)
• Sampling Frequency: Adjustable (typically 6.4kHz to 8kHz)
• Audio Output: Direct speaker drive (8Ω) or line-level output
• Non-Volatile Storage: No external memory required (built-in EEPROM)
• Operating Temperature Range: 0°C to +70°C
• Package Type: 28-pin DIP or SOIC

Descriptions:

• The ISD201 is a single-chip voice recorder/playback solution with analog storage technology.
• It eliminates the need for external ADCs/DACs by using direct analog storage in non-volatile memory.
• Supports single-message or multiple-message recording/playback modes.
• Features edge-activated or level-activated control for easy interfacing with microcontrollers or switches.

Features:

• Direct Analog Storage: No digital compression, ensuring high-quality audio.
• Low Power Consumption: Ultra-low standby current for battery-powered applications.
• Simple Interface: Minimal external components required.
• Multistage Addressing: Allows segmentation of memory for multiple messages.
• Automatic Power-Down: Enters standby mode when inactive.
• Durable Storage: Retains recordings for over 100 years (typical).

The ISD201 is commonly used in applications like voice memos, security systems, toys, and industrial voice prompts.
