Multi-Message Single-Chip Voice Record & Playback Devices


The Winbond® ISD1700 ChipCorder® Series is a high quality, fully integrated, single-chip multi
message voice record and playback device ideally suited to a variety of electronic systems. The
message duration is user selectable in ranges from 26 seconds to 120 seconds, depending on the
specific device.

Integrated message management systems for single-chip, push-button applications 
  o  REC:level-trigger for recording
  o  PLAY:edge-trigger for individual message or level-trigger for looping playback sequentially
  o  ERASE:edge-triggered erase for first or last message or level-triggered erase for all messages
  o  FWD:edge-trigger to advance to the next message or fast message scan during the playback
  o  VOL: 8 levels output volume control
  o  INT RDY : ready or busy status indication
  o  RESET: return to the default state
  o Automatic power-down after each operation cycle 
Message and operation indicators
  o Four customizable Sound Effects (SEs) for audible indication
  o Optional vAlert (voiceAlert) to indicate the presence of new messages
  o LED: stay on during recording, blink during playback, forward and erase operations 
Dual operating modes
  o  Standalone mode:
     ƒIntegrated message management techniques
     Automatic power-down after each operation cycle
  o  SPI mode:
    Fully user selectable and controllable options via APC register and various SPI commands
