ISD1600B SERIES  
1. GENERAL DESCRIPTION  
The Winbond® ISD1600B ChipCorder® Series is a high quality, fully integrated, single-chip single-  
message voice record and playback device ideally suited to a variety of electronic systems. The  
message duration is user selectable in ranges from 6.6 seconds to 40 seconds, depending on the  
specific device. The sampling frequency of each device can also be adjusted from 4 kHz to 12 kHz  
with an external resistor, giving the user greater flexibility in duration versus recording quality for each  
application. Operating voltage spans a range from 2.4 V to 5.5 V to ensure that the ISD1600B devices  
are optimized for a wide range of battery or line-powered applications.  
The devices include an on-chip oscillator (with external resistor control), microphone preamplifier with  
Automatic Gain Control (AGC), anti-aliasing filter, Multi-Level Storage (MLS) array, smoothing filter,  
Pulse Width Modulation (PWM) Class D speaker driver, and current output. Voice signals can be fed  
into the chip through a differential microphone input for recording. The PWM output can directly drive  
a standard 8 Ω speaker or a typical buzzer, while the separate single-ended current output can drive  
an external amplifier.  
Recordings are stored into the on-chip Flash memory cells, providing zero-power message storage.  
This unique single-chip solution is made possible through Winbond’s patented Multi-Level Storage  
(MLS) technology. Audio data are stored directly in solid-state memory without digital compression,  
providing superior quality voice and music reproduction.  
The ISD1600B Series also supports an optional “vAlert” (voiceAlert) feature that can be used as a  
new message indicator. With vAlert, the IC strobes an external LED to indicate that a new message is  
present.
