Product Summary

The Winbond’s ISD2548P single-chip, multiple-messages, voice record/playback device provides high-quality, single-chip, Record/Playback solutions for 32- to 64-second messaging applications. The ISD2548P includes an on-chip oscillator, microphone preamplifier, automatic gain control, antialiasing filter, smoothing filter, speaker amplifier, and high density multi-level storage array. In addition, the ISD2548P is microcontroller compatible, allowing complex messaging and addressing to be achieved. Recordings are stored into on-chip nonvolatile memory cells, providing zero-power message storage. This unique, single-chip solution is made possible through Winbond’s patented multilevel storage technology. Voice and audio signals of ISD2548P are stored directly into memory in their natural form, providing high-quality, solid-state voice reproduction.
