Overview
The Nuvoton ISD17240SYI is a single-chip multi-message voice record and playback device from the ISD1700 ChipCorder series. It features an operating voltage range of 2.4 V to 5.5 V and supports sampling frequencies from 4 kHz to 12 kHz, determined by an external resistor. The device offers a message duration of 160 to 480 seconds depending on the selected frequency. It includes an internal oscillator, microphone preamplifier with Automatic Gain Control (AGC), and a PWM Class D speaker driver capable of driving an 8 Ω load. The component operates in standalone push-button mode or via SPI interface and is housed in a 28-SOIC package.
Feature Summary
- Integrated message management system for standalone push-button applications
- Dual input channels including differential microphone with AGC and auxiliary analog input
- Dual output channels featuring PWM Class D speaker driver and configurable analog output
- Non-volatile storage using Multi-Level Storage (MLS) technology
Applications
- Standalone electronic messaging systems
- Voice-enabled consumer electronics
- Industrial control audio interfaces
- Security alarm voice prompts
Procurement Notes
Verify the specific suffix 'SYI' against the manufacturer's current ordering information to confirm package type and temperature grade. Confirm availability status as legacy components may have limited supply chains. Ensure design compliance with absolute maximum ratings during procurement planning.
Selection Notes
Select this model when message durations between 160 and 480 seconds are required. Choose based on the desired balance between recording quality and duration by adjusting the external oscillator resistor. Verify that the 28-SOIC package fits the PCB layout constraints and that the operating voltage range matches the system power supply.
Part Context
The ISD17240SYI belongs to the ISD1700 series, which provides high-quality voice recording without digital compression. This series utilizes patented Multi-Level Storage technology for direct solid-state memory storage. It is designed for both standalone microcontroller-independent operation and SPI-controlled environments.
Replacement Considerations
Other models in the ISD1700 series such as ISD1730, ISD1760, and ISD17120 offer different duration ranges. Check pin compatibility and software command sets if migrating between series members.
