ISD17150SYI

Overview

The ISD17150SYI is a fully integrated, single-chip multi-message voice record and playback device from the Nuvoton ChipCorder series. It features non-volatile message storage using patented Multi-Level Storage (MLS) technology, allowing for direct push-button operation or microcontroller control via SPI interface. The device supports user-selectable message durations ranging from 33 to 100 seconds with sampling frequencies adjustable between 4 kHz and 12 kHz. Operating voltage spans 2.4 V to 5.5 V, and it includes an internal oscillator, microphone preamplifier with Automatic Gain Control (AGC), volume control, and a PWM Class D speaker driver. The component is housed in a 28-SOIC package and operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrated Multi-Level Storage (MLS) array enables non-volatile message retention without external memory components.
• Proprietary message management system allows self-managed address locations for multiple messages in a simple push-button environment.
• On-chip microphone preamplifier with Automatic Gain Control (AGC) ensures consistent audio input levels.
• Built-in Pulse Width Modulation (PWM) Class D speaker driver provides direct output capability.

Applications

• Electronic systems requiring standalone voice messaging
• Microcontroller-integrated voice recording applications
• Battery-powered devices due to wide voltage support

Procurement Notes

The ISD17150SYI has reached End-of-Life status as of March 25, 2024. Verification of current availability should be conducted through authorized distributors, noting that stock levels may be limited. Engineers are advised to review the Product Change Notification (PCN) and consider manufacturer-recommended substitutes such as the I2361YYI or I3800FYI for new designs to ensure long-term supply chain stability.

Selection Notes

Select this component when a fully integrated solution for multi-message voice recording is required without external memory. The choice depends on the need for specific duration ranges (33-100 seconds) and sampling rates (4-12 kHz). Consider the 28-SOIC package constraints and the requirement for either standalone button control or SPI interface compatibility with the host system.

Part Context

This part belongs to the ISD1700 ChipCorder series, which offers high-quality, fully integrated voice recording capabilities. The series is designed for various electronic systems, providing flexibility in message duration and quality through adjustable sampling frequencies. It represents a specialized line of analog-to-digital voice interfaces distinct from general-purpose microcontrollers.

Replacement Considerations

Manufacturer recommended substitutes include I2361YYI and I3800FYI. Verify pinout compatibility and functional equivalence before replacement, as these parts belong to the same family but may have different specifications or packaging options.
