7. FUNCTIONAL DESCRIPTION
Speech/Sound Quality
Winbond’s patented ChipCorder
ISD1100 series include devices of 5.3 kHz and 6.4 kHz sampling frequencies, allowing the user a
choice of speech quality options. The input voice signals are stored directly into non-volatile EEPROM
cells and are reproduced without the synthetic effect often heard with digital solid-state speech
solutions. A complete sample is stored in a single cell, minimizing the memory necessary to store a
recording of a given duration.
Duration
The ISD1100 series offer single-chip solutions of 10 and 12 seconds duration.
EEPROM Storage
One of the benefits of Winbond’s ChipCorder
providing zero-power message storage. The message is retained for up to 100 years typically without
power. In addition, the device can be re-recorded typically over 100,000 times.
Basic Operation
The ISD1100 ChipCorder
control signals, PLAYE (edge-activated playback), and PLAYL (level-activated playback). The
ISD1100 series parts are configured for simplicity of design in a single/multiple-message application.
Using the address lines will allow multiple message applications.
Automatic Power-Down Mode
At the end of a playback or record operation, the ISD1100 series automatically enters into a standby
mode, with typically 0.5 µA current. During a playback cycle, the device powers down automatically at
the end of the message. During a record cycle, the device powers down immediately after REC is
released HIGH.
