Overview
The Nuvoton ISD17210SYIR is a single-chip multi-message voice record and playback device belonging to the ISD1700 ChipCorder series. It utilizes patented Multi-Level Storage (MLS) technology for non-volatile message storage, eliminating the need for external memory. The device supports user-selectable message durations ranging from 60 to 210 seconds, depending on the specific sampling frequency configuration. Sampling frequencies are adjustable between 4 kHz and 12 kHz via an external resistor, allowing flexibility in recording quality versus duration. Operating voltage spans 2.4 V to 5.5 V, suitable for battery or line-powered applications. It features an internal oscillator, microphone preamplifier with Automatic Gain Control (AGC), volume control, and a Pulse Width Modulation (PWM) Class D speaker driver. The package type is 28-SOIC.
Feature Summary
- Patented Multi-Level Storage (MLS) array enables non-volatile message storage without external components.
- Integrated message management system allows self-managing address locations for multiple messages in a simple push-button environment.
- On-chip microphone preamplifier includes Automatic Gain Control (AGC) and auxiliary analog input capabilities.
- Built-in Pulse Width Modulation (PWM) Class D speaker driver provides direct audio output capability.
Applications
- Electronic systems requiring standalone voice messaging
- Battery-operated devices needing low voltage operation
- Microcontroller-integrated voice interfaces via SPI mode
Procurement Notes
Verify component authenticity through authorized distributors as datasheets may be hosted by third-party vendors. Confirm the specific suffix indicates the correct package variant. Check current product status as older ISD17xx models may have discontinuation notices. Ensure supply chain stability for long-term production runs.
Selection Notes
Select this model when message durations between 60 and 210 seconds are required. Choose based on desired sampling frequency trade-offs between sound quality and recording time. Verify compatibility with 2.4 V to 5.5 V power supplies. Consider SPI interface requirements if microcontroller integration is planned over standalone button operation.
Part Context
This component is part of the Nuvoton ISD1700 ChipCorder series, which offers various message duration options. Related parts include the ISD17120SYIR (60-210s range) and ISD1730SYI (26-120s range). All share similar MLS technology and PWM output features but differ in maximum recording capacity and specific timing configurations.
Replacement Considerations
Direct substitutes within the same family include ISD17120SYIR for similar functionality with potentially different duration ranges. Cross-manufacturer replacements require verifying MLS compatibility and PWM driver specifications. Ensure pinout and voltage levels match before substitution.
