ISD1416PY

Overview

The ISD1416PY is a single-chip voice record/playback device from the ISD1400 series, manufactured by Nuvoton Technology Corporation. It features a 16-second recording duration with an 8.0 kHz sampling frequency and a 3.3 kHz filter passband. The component operates on a single +5V supply (4.5V to 5.5V) and includes an internal oscillator, microphone preamplifier with automatic gain control, and a Class D speaker amplifier. It utilizes patented Multi-Level Storage (MLS) technology for non-volatile memory, ensuring zero-power message storage. The device supports multiple messages via address inputs and offers edge- or level-activated playback.

Feature Summary

• Direct analog storage using Multi-Level Storage (MLS) technology for natural voice reproduction without digitization.
• Integrated microphone preamplifier with Automatic Gain Control (AGC) and differential input capability.
• Built-in Class D PWM speaker driver capable of directly driving low-impedance speakers.
• Automatic power-down mode with ultra-low standby current consumption.

Applications

• Short-duration messaging systems
• Voice prompts in consumer electronics
• Toy and gift market audio modules
• Industrial announcement devices

Procurement Notes

Verify the specific ordering suffix 'PY' against the manufacturer's official documentation to confirm lead-free PDIP packaging compliance. Confirm the current product status, as ISD1400 series components may be subject to discontinuation or lifecycle changes. Ensure compatibility with existing design specifications regarding voltage and temperature ranges before procurement.

Selection Notes

Select the ISD1416PY when a fixed 16-second duration at 8.0 kHz sampling rate is required. Choose this model over the ISD1420 if higher speech quality is prioritized over longer recording time. Consider the industrial temperature range (-40°C to 85°C) availability for the packaged version if operating in extreme environments. Ensure the application supports single-ended or differential microphone inputs as per the AGC configuration.

Part Context

The ISD1416PY belongs to the ISD1400 ChipCorder series, which provides high-quality, single-chip solutions for short-duration messaging. This series is designed for standalone applications or microcontroller integration, offering easy-to-use record/playback functionality with minimal external components.

Replacement Considerations

The ISD1420 is a compatible alternative within the same series, offering a 20-second duration at a 6.4 kHz sampling frequency. Verify pinout and electrical parameter differences before substitution.
