The following
products are EOL (End Of Life) and no longer supported by Winbond Electronics
Corporation. Winbond makes every effort to inform all customers, distributors
and agents about any change in status on product support, and strives
to give 6 months’ notice of a planned product obsolescence in which
time the customer can order lifetime buy quantities. In cases where an
exact or functional replacement are available, we have listed the alternative
below. In all cases, though, it is highly recommended to consult the product
datasheet and/or contact your Winbond representative regarding these parts.
Any product recommendations made for non-Winbond components are based
on publicly available information only and are not guarantees of product
performance or functional specifications.
Winbond’s
ISD1200 ChipCorder® series provides high-quality, single-chip, Record/Playback
solutions to 10- and 12-second messaging applications. The CMOS devices
include an on-chip oscillator, microphone preamplifier, automatic gain
control, antialiasing filter, smoothing filter, and speaker amplifier.
A minimum Record/Playback subsystem can be configured with a microphone,
a speaker, several passives, two push buttons, and a power source. Recordings
are stored in on-chip nonvolatile memory cells, providing zero-power message
storage. This unique, single-chip solution is made possible through Winbond’s
patented multilevel storage technology. Voice and audio signals are stored
directly into memory in their natural form, providing high-quality, solid-state
voice reproduction. |

Application Notes:
AB3
Using an ISD1100 in a Circuit Intended for an ISD1200
This brief tells how to use the ISD1100 as a substitute for the ISD1200 in prototyping
circuits. It notes the location of internal pull-up and pull-down resistors
in the ISD1100, and gives a sample circuit that will work equally well for the
ISD1110 or the ISD1210. It also explains a little bit about interfacing a microcontroller
to these chips.

AB4
Using the ISD1100/1200/1400 with External Clocking
This brief explains how to use the ISD1100/1200/1400 devices with an external
clock, such as would be needed in AB2 to reproduce DTMF frequencies accurately.
Using an external clock is more complicated for the ISD1100/1200/1400 series
than it is for the ISD1000A series.

AB7
Automatic Power-Up Looping for the ISD1100, ISD1200, and ISD1400 Devices
This brief explains how to use the ISD1100/1200/1400 devices in an automatic
looping upon power-up situation. In this application, the circuit starts looping
on the single message at address 0 when power is applied. This is easy to accomplish
with the ISD1000A series, but requires additional components to do it with the
ISD1100/1200/1400 devices. An example circuit schematic is included.

AB10
Dividing the ISD1100, ISD1200, and ISD1400 Products into Fixed Message and
ReRecordable Message Segments
This brief provides an example circuit schematic explaining how to divide an
ISD1100/1200/1400 device into two messages. The chip has a “permanent” message
and a user-programmable message. The first one is programmed by the manufacturer
of the product and is intended to be permanent. The second is rerecordable by
the consumer.

Using the ISD-ES001 Evaluation System with ISD1100, ISD1200, and ISD1400
Products
This brief explains how to use the ISD-ES001 Evaluation System with the newer
ISD1100/1200/1400 parts. The ISD-ES001 was designed and labeled for the ISD1000A
series parts before the newer parts were introduced. It is able to demonstrate
the new parts, but the switch labels need to be modified and a jumper or two
moved. This is explained for both the original ISDES001 and the current revision,
the ISD-ES001D.

Using Speaker Outputs as a Playback “Run” Indicator in the ISD1100, ISD1200,
and ISD1400 Devices
This brief illustrates a way of deriving a “run” signal from the device. Many
applications require an indication of when playback is occurring. This circuit
provides that information, in addition to an LED indicator with a minimum of
additional components.
