This document introduces the ISD1400 series of single-chip voice record/playback devices, including 16- and 20-second duration devices. These devices support both single-byte and double-byte encoding formats, and can operate over a wide range of voltage.
The ISD1400 Series provides high-quality, single-chip record/playback solutions for short-duration messaging applications. These CMOS devices utilize patented multilevel storage technology to store voice and audio signals directly into on-chip nonvolatile memory cells without digitization or compression.
Key features include an integrated oscillator, microphone preamplifier, automatic gain control, antialiasing filter, smoothing filter, and speaker amplifier. The series offers two specific part numbers: the ISD1416 with a 16-second duration and the ISD1420 with a 20-second duration.
| Message Retention | 100-year message retention (typical) |
|---|---|
| Record Cycles | 100,000 record cycles (typical) |
| Standby Current | 0.5 pA (typical) |
The series offers single-chip solutions at 16 and 20 seconds.
No, no programmer or development system is needed for these devices.
The device operates with a single +5 volt power supply.
