Overview
The ISD17240SYI01 is a multi-message single-chip voice record and playback device from the ISD1700 series. It supports message durations ranging from 160 seconds to 480 seconds, depending on the sampling frequency selected via an external resistor. The sampling frequency is adjustable between 4 kHz and 12 kHz. Operating voltage spans 2.4 V to 5.5 V. The device features integrated message management for standalone push-button operation or microcontroller control via SPI mode. Key components include a microphone preamplifier with Automatic Gain Control (AGC), Multi-Level Storage (MLS) array, PWM Class D speaker driver, and optional vAlert feature.
Feature Summary
- Integrated message management system enabling standalone push-button operation without external microcontrollers.
- Dual operating modes including standalone mode and full user control via SPI interface.
- Patented Multi-Level Storage (MLS) technology for non-volatile audio data storage without digital compression.
- Built-in Automatic Gain Control (AGC) for differential microphone input and auxiliary analog input support.
Applications
- Electronic systems requiring high-quality voice recording and playback
- Battery-powered applications due to wide operating voltage range
- Line-powered electronic devices
- Push-button controlled messaging environments
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type, temperature rating, and special features such as vAlert. Ensure compatibility with required sampling frequencies and message durations by checking the external oscillator resistor values. Confirm lead-free status if specified in the procurement requirements.
Selection Notes
Select this component based on the required message duration and sampling frequency combination. The ISD17240 variant provides up to 480 seconds at 4 kHz. Choose the appropriate package (SOIC, PDIP, TSOP) based on PCB layout constraints. Consider the industrial temperature range (-40°C to +85°C) if operating in harsh environments. Verify power supply stability within the 2.4 V to 5.5 V range.
Part Context
The ISD17240SYI01 belongs to the Winbond ISD1700 ChipCorder series, which are fully integrated single-chip voice record and playback devices. This series utilizes patented Multi-Level Storage (MLS) technology to store audio data directly in solid-state memory. The ISD1700 series offers flexibility in message duration and sampling frequency, making it suitable for various electronic systems requiring voice functionality.
Replacement Considerations
Other models within the ISD1700 series, such as ISD1730, ISD1740, ISD1750, ISD1760, ISD1790, ISD17120, ISD17150, ISD17180, and ISD17210, offer different message duration ranges. When replacing, ensure the new model's duration specifications meet the application requirements. Pinout compatibility should be verified across packages.
