ISD4002 Series Single-Chip Voice Record/Playback Devices 120-, 150-, 180-, and 240-Second Durations GENERAL DESCRIPTION The ISD4002 ChipCorder(R) products provide highquality, 3-volt, single-chip record/playback solutions for 2- to 4-minute messaging applications ideal for cellular phones and other portable products. The CMOS-based devices include an onchip oscillator, anti-aliasing filter, smoothing filter, AutoMuteTM feature, audio amplifier, and high density, multilevel Flash storage array. The ISD4002 series is designed to be used in a microprocessor- or microcontroller-based system. Address and control are accomplished through 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, providing high-quality voice reproduction.

Typical values: TA = 25C 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 16 mVp-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 570 mVp-p with VIN at 32 mVp-p. 9. For optimal signal quality, this maximum limit is recommended. 10. When a record command is sent, TRAC = TRAC + TRACLO on the first row addressed. 10 Voice Solutions in SiliconTM ,6'6HULHV Table 8: Absolute Maximum Ratings (Die)(1) Condition Table 9: Operating
