ISD17120PYI01

Overview

The ISD1700 Series is a multi-message single-chip voice record and playback device utilizing Multi-Level Storage (MLS) technology. The ISD17120PYI01 variant provides selectable message durations ranging from 80 seconds to 240 seconds, depending on the sampling frequency set between 4 kHz and 12 kHz via an external resistor. It operates within a supply voltage range of 2.4 V to 5.5 V and supports both standalone push-button mode and microcontroller SPI interface mode. The device integrates an on-chip oscillator, microphone preamplifier with Automatic Gain Control, PWM Class D speaker driver, and analog output.

Feature Summary

• Integrated message management system enabling standalone operation with automatic power-down after each cycle
• Dual operating modes including fully controllable SPI interface for random memory access
• Direct drive capability for 8 Ω speakers or buzzers via PWM Class D outputs
• On-chip flash storage providing zero-power message retention without digital compression

Applications

• Electronic greeting cards and toys requiring simple push-button voice interaction
• Industrial control panels needing audio confirmation for operations
• Home appliances incorporating voice prompts and status alerts
• Security systems utilizing voice-activated commands or alarms

Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm lead-free status if RoHS compliance is mandatory. Ensure the specific duration variant aligns with the target application's timing requirements before finalizing procurement orders.

Selection Notes

Select the ISD17120PYI01 when extended recording times are necessary compared to shorter duration models. Choose this part for applications requiring industrial temperature ranges and TSOP packaging. Evaluate the trade-off between sampling frequency and message duration based on the specific audio quality needs of the design.

Part Context

This component belongs to the Winbond ISD1700 ChipCorder series, designed for high-quality voice reproduction in embedded systems. The series utilizes proprietary MLS technology to store audio data directly in solid-state memory. The ISD17120 model specifically targets applications requiring longer message lengths than the base line variants.

Replacement Considerations

ISD17150PYI01 offers increased duration options up to 300 seconds. ISD17090PYI01 provides shorter durations suitable for compact designs. Verify pin compatibility and software configuration differences when substituting other members of the ISD1700 family.
