6. FUNCTIONAL DESCRIPTION
6.1. D
6.1.1 Audio Quality
Winbond’s patented ChipCorder
playback solution on a single chip. The input audio signals are stored directly into the non-
volatile memory and are reproduced in its natural form without any compression artifacts
caused by the digital speech solutions. A complete sample is stored in a single cell,
minimizing the memory needed to store a single message.
6.1.2 Duration
The ISD1600B series offer single-chip solution with record & playback duration from 6.6
seconds to 40 seconds. Sampling frequency and duration are determined by an external
resistor connected to the Rosc pin.
6.1.3 Flash Storage
The ISD1600B product utilizes the on-chip Flash memory providing zero-power message
storage. The message is retained for up to 100 years without power. In addition, the device
can be re-recorded typically over 100,000 times.
6.1.4 Basic Operation
The ISD1600B ChipCorder
playback modes,
in single-message application. Detailed operations are explained in Section 6.2.
6.1.5 vAlert
With vAlert option, after Record, the LED blinks slowly to indicate a new message exists.
Once playback is performed, the LED will not blink again and resume to normal operating
conditions.
6.1.6 Automatic Power-Down Mode
At the end of a playback or record cycle, the
power mode, consuming typically 1µA, provided that
(see DC parameters Section). During a playback cycle, the device powers down automatically
