ISD1600 SERIES
1. GENERAL DESCRIPTION
Winbond’s ISD1600 Series ChipCorder® is a single-message, single chip, record/playback solution
with selectable durations from 6.6 to 40 seconds. The CMOS device includes an on-chip oscillator (via
external control), microphone preamplifier, automatic gain control, anti-aliasing filter, Multi-Level
Storage (MLS) array, smoothing filter, PWM Class D speaker amplifier for standard 8Ω speaker or
buzzer, plus an extra current output. Recording is stored into the embedded Flash memory cells,
providing zero-power message storage. This unique single-chip solution ultilizes Winbond’s patented
MLS technology. Therefore, voice or audio data are stored directly into the memory in their natural
form without any compressions alike digital approach, providing high-quality, solid-state audio
reproduction. The device enters into standby mode automatically once an operation is completed for
power saving purposes.
Moreover, a minimum record/playback subsystem can be configured with a microphone, a speaker or
buzzer, several passive components, two push buttons, and a power source.
