Overview

The ISD1750X is a voice recording and playback integrated circuit from the ChipCorder series by Nuvoton Technology Corporation. It supports multiple messages with durations ranging from 33 to 100 seconds. The device features an internal oscillator and operates on a supply voltage of 2.4 V to 5.5 V. Input signals are analog single-ended, accepting microphone inputs, while outputs include analog single-ended and PWM speaker drive. Sampling frequencies range from 4 kHz to 12 kHz. Interfaces include buttons and SPI. The component is housed in a 28-SOIC package (0.295 inch width) and operates within a temperature range of -40°C to 85°C.

Feature Summary

Integrated automatic gain control and volume control for consistent audio quality.
Supports multiple message storage with variable duration capabilities.
Combines button interface and SPI protocol for flexible system integration.

Applications

Voice messaging systems
Automated announcements
Educational toys

Procurement Notes

Verify component status as the ISD1750SYI01 variant is listed as obsolete. Confirm availability of recommended substitutes such as I2361YYI or I3800FYI from Nuvoton Technology Corporation. Ensure design-in compatibility with existing PCB layouts and software drivers before procurement.

Selection Notes

Select based on required message duration between 33 and 100 seconds. Verify power supply constraints against the 2.4 V to 5.5 V operating range. Consider the 28-SOIC package size for board space limitations. Check sampling frequency requirements against the 4 kHz to 12 kHz capability.

Part Context

The ISD1750X belongs to the ChipCorder series, designed for standalone voice recording and playback applications. It eliminates the need for external microcontrollers or memory chips by integrating all necessary functions into a single IC. This series is commonly used in cost-sensitive consumer electronics requiring simple voice interaction.

Replacement Considerations

Recommended substitutes include I2361YYI and I3800FYI from Nuvoton Technology Corporation. Verify pinout compatibility and functional equivalence before replacement. Note that the original part may be end-of-life.
