2 / 47 page  ISD5008 Product ii Voice Solutions in Silicon™ Duration/sample rate selection is accomplished via software, allowing customers to optimize qual- ity and duration for various features within the same end product. The ISD5008 device is designed for use in a micro- processor- or microcontroller-based system. Ad- dress, control, and duration selection are accomplished through a Serial Peripheral Inter- face (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, un- compressed form, providing superior quality voice and music reproduction. ISD5008 FEATURES FULLY-INTEGRATED SOLUTION • Single-chip voice record/playback solution • Integrated sampling clock, anti-aliasing and smoothing filters, and multi-level storage array • Integrated analog features such as automatic gain control (AGC), audio gating switches, speaker driver (23mW with 8 ohm load), summing amplifiers, volume control, and an AUX IN/AUX OUT interface (e.g., for car kits). LOW-POWER CONSUMPTION • Single +3 volt supply • Operating current: I CC Play = 15 mA (typical) I CC Rec = 25 mA (typical) I CC Feedthru = 12 mA (typical) • Standby current: I SB = 1 µA • Power consumption controlled by SPI or Microwire control register • Most stages can be individually powered down for minimum power consumption ENHANCED VOICE FEATURES • One or two-way (full duplex) conversation record (record signal summation) • One- or two-way (full duplex) message playback (while on a call) • Voice memo record and playback • Private call screening • In-terminal answering machine • Personalized outgoing message (given caller ID information from host chip set) • Private call announce while on call (given CIDCW information from host chip set) EASY-TO-USE AND CONTROL • No compression algorithm development required • User-controllable sample rates of 8.0 kHz, 6.4 kHz, 5.3 kHz, or 4.0 kHz providing up to 8 minutes of voice storage. • Microcontroller SPI or Microwire™ Serial Interface • Fully addressable to handle multiple messages in 1200 rows HIGH QUALITY SOLUTION • High quality voice and music reproduction • ISD’s standard 100-year message retention (typical) • 100,000 record cycles (typical) OPTIONS • Available in die form, PDIP, SOIC, TSOP, and chip scale packaging (CSP) • Compact µBGA chip scale package available for portable applications • Extended temperature (-20 to +70°C) and industrial temperature (-40 to +85°C) versions available |
