Overview
The ISD17120SY01 is a multi-message single-chip voice record and playback device from the Winbond ISD1700 series. It features user-selectable message durations ranging from 80 to 240 seconds, depending on the sampling frequency. The sampling frequency can be adjusted between 4 kHz and 12 kHz using an external resistor. Operating voltage spans 2.4 V to 5.5 V. The device supports standalone push-button operation or microcontroller SPI mode. Key components include an on-chip oscillator, microphone preamplifier with Automatic Gain Control (AGC), auxiliary analog input, Multi-Level Storage (MLS) array, PWM Class D speaker driver, and configurable analog output.
Feature Summary
- Integrated message management system for standalone push-button applications
- Dual operating modes: Standalone and SPI interface control
- Direct storage of audio data in solid-state memory without digital compression
- Automatic power-down after each operation cycle for power conservation
Applications
- Electronic systems requiring high-quality voice recording and playback
- Battery-powered or line-powered devices needing flexible duration options
- Applications utilizing push-button interfaces for simple messaging
- Systems integrating microcontrollers via SPI for advanced control
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, temperature range, and lead-free status. Ensure compatibility with the required sampling frequency and message duration specifications for your application design.
Selection Notes
Select based on required message duration and sampling frequency combinations. Choose between standalone or SPI mode based on system complexity. Consider packaging options such as TSOP, SOIC, or PDIP according to PCB layout constraints.
Part Context
The ISD17120SY01 belongs to the Winbond ISD1700 ChipCorder series, which utilizes patented Multi-Level Storage technology. This series provides fully integrated voice recording and playback solutions suitable for various electronic systems requiring natural voice reproduction.
Replacement Considerations
Other models within the ISD1700 series offer different message durations. Verify pinout compatibility and functional equivalence before substitution. Consult the manufacturer for updated alternatives if discontinuation occurs.
