6. FUNCTIONAL DESCRIPTION
6.1. DETAILED DESCRIPTION
Speech/Sound Quality
The Winbond’s ISD1400 series offer 6.4 and 8.0 kHz sampling frequencies, allowing the user a choice
of speech quality options. The speech samples are stored directly into on-chip non-volatile memory
without the digitization and compression associated with other solutions. Direct analog storage
provides a very true, natural sounding reproduction of voice, music, tones, and sound effects not
available with most solidstate digital solutions.
Duration
To meet end system requirements, the ISD1400 series offer single-chip solutions at 16 and 20
seconds.

EEPROM Storage
One of the benefits of Winbond’s ChipCorder
technology is the use of on-chip non-volatile memory,
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 ISD1400 ChipCorder
series are controlled by a single control signal, REC , PLAYE (edge-
activated playback) or PLAYL (level-activated playback). The ISD1400 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 cycle, the ISD1400 series automatically return to a low-power
standby mode, consuming typically 0.5 A. After a playback cycle, the device powers down
automatically at the end of the message. After a record cycle, the device powers down immediately
after REC is pulled to HIGH.
