ISD17180PY01

Overview

The ISD17180PY01 is a multi-message single-chip voice record and playback device from the Winbond ISD1700 series. It features 120 seconds of recording duration at 12 kHz sampling frequency, extending to 360 seconds at 4 kHz. The device operates on a supply voltage ranging from 2.4 V to 5.5 V and supports industrial temperature ranges up to +85°C. It utilizes Multi-Level Storage (MLS) technology for direct audio storage in Flash memory without digital compression. Key electrical parameters include a typical standby current of 1 µA, speaker output power of 670 mW at 5.5 V into an 8 Ω load, and 8 levels of volume control.

Feature Summary

• Integrated message management system enabling standalone push-button operation with automatic power-down after each cycle.
• Dual operating modes allowing either standalone control or full microcontroller management via a 4-wire SPI interface.
• Direct drive capability through a PWM Class D speaker output that can power an 8 Ω speaker or buzzer without external amplification.
• Flexible audio input paths supporting differential microphone signals with Automatic Gain Control (AGC) and a single-ended auxiliary analog input.

Applications

• Voice messaging systems requiring simple push-button interaction
• Industrial equipment with voice alert or status feedback requirements
• Consumer electronics utilizing integrated voice prompts
• Security alarm systems needing recorded confirmation messages

Procurement Notes

Verify the specific suffix 'Y' against manufacturer documentation to confirm lead-free compliance status. Ensure the package type matches the required PCB footprint, as the ISD1700 series is available in TSOP, SOIC, and PDIP configurations. Confirm the industrial temperature rating aligns with the operational environment specifications.

Selection Notes

Select this component when fixed message durations between 120 and 360 seconds are sufficient for the application. Consider the ISD1700 series if direct speaker driving is preferred over complex amplifier circuits. Evaluate the standalone versus SPI mode requirements, as the latter allows for dynamic address management and flexible audio path configuration via the APC register.

Part Context

The ISD17180PY01 belongs to the Winbond ISD1700 ChipCorder series, which provides high-quality voice reproduction using proprietary MLS technology. This series eliminates the need for separate Flash memory and DSP components by integrating all necessary audio processing functions onto a single chip. The part number indicates a 120-second duration variant within the broader family of devices offering various recording lengths.

Replacement Considerations

ISD17150: Offers 100 seconds duration at 12 kHz. ISD17210: Provides 140 seconds duration at 12 kHz. ISD17240: Supports 160 seconds duration at 12 kHz. All variants share identical pinouts and functional characteristics, differing only in memory capacity and resulting message duration.

FAQ

How is the sampling frequency determined?

The sampling frequency is set by connecting an external resistor to the ROSC pin. Standard values range from 53 kΩ for 12 kHz to 160 kΩ for 4 kHz.

Can the device operate without a microcontroller?

Yes, the ISD1700 series supports a Standalone Mode where operations like Record, Play, Erase, and Forward are initiated directly via hardware buttons connected to dedicated pins.

What is the vAlert feature?

vAlert is an optional feature that flashes an external LED to indicate the presence of a new message, providing a visual notification mechanism independent of audio playback.
