GENERAL DESCRIPTION
The ISD4002 ChipCorder® products provide high-
quality, 3-volt, single-chip record/playback solu-
tions for 2- to 4-minute messaging applications
ideal for cellular phones and other portable prod-
ucts. The CMOS-based devices include an on-
chip oscillator, anti-aliasing filter, smoothing filter,
AutoMute™ feature, audio amplifier, and high
density, multilevel Flash storage array. The
ISD4002 series is designed to be used in a micro-
processor- or microcontroller-based system.
Address an d co ntrol are acco mplish ed t hrough a
Serial Peripheral Interface (SPI) or Microwire Serial
Interface to minimize pin count.
Recordings are stored in on-chip nonvolatile
memory cells, providing zero-power message
storage. This unique, single-chip solution is made
possible through ISD’s patented multilevel storage
technology. Voice and audio signals are stored
directly into solid-state memory in their natural
form, p rovid in g high-quality voice reproduction.

ISD
1. Typical values: TA = 25°C and 3.0 V.
2. All min/max limits are guaranteed by ISD via electrical testing or characterization. Not all specifications are 100
percent tested.
3. VCCA and VCCD connected together.
4. SS = VCCA = VCCD, XCLK = MOSI = VSSA= VSSD and all other pins floating.
5. Measured with AutoMute feature disabled.

10 Voice Solutions in Silicon™
1. Typical values: TA = 25°C and 3.0 V
2. All min/max limits are guaranteed by ISD via electrical testing or characterization. Not all specifications are 100
percent tested.
3. Low-frequency cut off depends upon the value of external capacitors (see Pin Descriptions).
4. Single-ended input mode. In the differential input mode, VIN maximum for ANA IN+ and ANA IN– is 16mVp-p.
5. Sampling Frequency can vary as much as ±2.25 percent over the commercial temperature, and voltage ranges,
and –6/+4 percent over the extended temperature, industrial temperature and voltage ranges. For greater
stability, an external clock can be utilized (see Pin Descriptions).
6. Playback and Record Duration can vary as much as ±2.25 percent over the commercial temperature and voltage
ranges, and –6/+4 percent over the extended temperature, industrial temperature and voltage ranges. For
greater stability, an external clock can be utilized (see Pin Descriptions).
7. Filter specification applies to the anti-aliasing filter and the smoothing filter. Therefore, from input to output, expect
a 6dB drop by nature of passing through both filters.
8. The typical output voltage will be approximately 570mVp-p with VIN at 32mVp-p.
9. For optimal signal quality, this maximum limit is recommended.
10. When a record command is sent, TRAC =T
RAC +T
RACLO on the first row addressed.
