ISD1720SY

The ISD1720SY belongs to the ISD1700 series. It is available in small outline integrated circuit (SOIC) package and lead-free. The following is some information about the ISD1700 series. The ISD1700 series is a kind of fully integrated, single-chip multimessage voice record and playback device. It is intended for operation in either standalone or microcontroller (SPI) mode. The device includes a proprietary message management system that allows the chip to self-manage address locations for multiple messages.

There are some features of ISD1720SY as follows. First is integrated message management systems for single-chip, push-button applications. The second is a wide range selection from 20 secs to 480 secs pending upon sampling frequency chosen. Then is message and operation indicators. Next is dual operating modes including standalone mode and SPI mode. Besides, it has two individual input channels which are MIC+/MIC- and AnaIn. The sixth is ChipCorder standard features including high-quality, natural voice and audio reproduction, 2.4 V to 5.5 V operating voltage, 100-year message retention (typical) and 100,000 record cycles (typical).
