ISD2548P

Voice Record And Playback Overview

The ISD2548P is a single-chip, multiple-message voice record/playback device from the Winbond ISD2500 series. It provides a 48-second recording duration using CMOS technology with on-chip nonvolatile multilevel storage. The device integrates an oscillator, microphone preamplifier, automatic gain control, filters, and a speaker amplifier. It operates on a single 5V supply and supports microcontroller or manual switch interfaces. Recordings are stored directly in memory without digitization, ensuring natural audio reproduction.

Direct analog storage of voice signals for high-quality natural reproduction
Microcontroller compatible with fully addressable message handling
Zero-power message storage eliminating battery backup requirements

Voice Record And Playback Applications

Car stereo messaging systems
Handset voice prompts
Transformer-based voice modules

Voice Record And Playback Procurement Notes

Verify the manufacturer designation as Winbond, as Nuvoton may list legacy inventory. Confirm the package type matches the required form factor, such as SOIC, PDIP, or TSOP. Check for RoHS compliance status if environmental regulations apply to the specific production batch. Ensure the operating temperature range meets the commercial requirements of the target application environment.

Voice Record And Playback Selection Notes

Select the ISD2548P when a 48-second duration is required. Compare sampling rates against other models; this unit uses a 5.3 kHz rate. Consider cascading capabilities if longer durations are needed. Evaluate the push-button mode availability for simplified interface designs. Verify power supply constraints align with the single 5V requirement.

Voice Record And Playback Part Context

This component belongs to the ISD2500 ChipCorder series, which utilizes patented multilevel storage technology. The series includes variants with 32, 40, 48, and 64-second durations. These devices are designed for consumer electronics applications requiring solid-state voice recording without external memory components.
