ISD17210SY

Overview

The ISD17210SY is a multi-message single-chip voice record and playback device from the Nuvoton ISD1700 ChipCorder Series. It features non-volatile message storage using patented Multi-Level Storage (MLS) technology, allowing for user-selectable message durations ranging from 26 to 120 seconds. The sampling frequency is adjustable from 4 kHz to 12 kHz via an external resistor, providing flexibility in recording quality versus duration. Operating voltage spans 2.4 V to 5.5 V, supporting both battery and line-powered applications. The device supports stand-alone or microcontroller (SPI) modes and includes an on-chip oscillator, microphone preamplifier with Automatic Gain Control (AGC), auxiliary analog input, anti-aliasing filter, smoothing filter, volume control, PWM Class D speaker driver, and current output.

Feature Summary

• Non-volatile message storage utilizing patented Multi-Level Storage (MLS) array
• Integrated proprietary message management system for self-managing address locations
• Built-in microphone preamplifier with Automatic Gain Control (AGC)
• Supports operation in either stand-alone or microcontroller SPI mode

Applications

• Electronic systems requiring multi-message voice prompts
• Battery-operated devices due to wide operating voltage range
• Applications needing flexible message duration and quality adjustment

Procurement Notes

Verify the specific suffix 'SY' against official Nuvoton documentation to confirm package type and temperature grade. Ensure compatibility with the ISD1700 series design guidelines regarding external resistor selection for sampling frequency and voltage requirements. Confirm availability through authorized distributors as component lifecycles may vary.

Selection Notes

Select this component when non-volatile voice storage without external memory is required. Consider the ISD1700 series for applications needing simple push-button messaging or SPI-controlled complex sequences. Evaluate the trade-off between sampling frequency and message duration based on the external resistor configuration. Ensure the power supply meets the 2.4 V to 5.5 V operating range.

Part Context

The ISD17210SY belongs to the ISD1700 ChipCorder Series, which are high-quality, fully integrated single-chip voice record and playback devices. This series is designed for various electronic systems, offering sophisticated messaging flexibility in a simple environment. The product line continues the legacy of Winbond's logic IC business, now under Nuvoton Technology Corporation.

Replacement Considerations

Check for other models within the ISD1700 series that offer different message durations or sampling frequencies if the ISD17210SY does not meet specific timing requirements. Verify pin-to-pin compatibility if substituting with other variants in the same package.
