ESCRIPTION
Audio Quality
The Winbond’s ISD4003 ChipCorder
frequencies, allowing the user a choice of speech quality options. Increasing the sampling frequency
will produce better sound quality, but affects duration. Please refer to Table 1: Product Summary for
details.
Analog speech samples are stored directly into on-chip non-volatile memory without the digitization
and compression associated with other solutions. Direct analog storage provides higher quality
reproduction of voice, music, tones, and sound effects than other solid-state solutions.
Duration
The ISD4003 Series is a single-chip solution with 4-, 5-, 6-, and 8-minute duration.

* This is the –3dB point. This parameter is not checked during production testing and may vary due to process
variations and other factors. Therefore, the customer should not rely upon this value for testing purposes.
Flash Storage
The ISD4003 series utilizes on-chip Flash 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.
Memory Architecture
The ISD4003 series contains a total of 1,920K Flash memory cells, which is organized as 1,200 rows
of 1,600 cells each.
®
series is offered at 8.0, 6.4, 5.3 and 4.0 kHz sampling
