ISD1700 SERIES

2 FEATURES

Integrated message management systems for single-chip, push-button applications

REC : level-trigger for recording

PLAY : edge-trigger for individual message or level-trigger for looping playback sequentially

ERASE : edge-triggered erase for first or last message or level-triggered erase for all messages

FWD : edge-trigger to advance to the next message or fast message scan during the playback

VOL : 8 levels output volume control

: ready or busy status indication

RDY INT

RESET : return to the default state

o Automatic power-down after each operation cycle

Selectable sampling frequency controlled by an external oscillator resistor

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:

Integrated 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

Two individual input channels

o MIC+/MIC-: differential microphone inputs with AGC (Automatic Gain Control)

o AnaIn: single-ended auxiliary analog input for recording or feed-through

Dual output channels

o Differential PWM Class D speaker outputs directly drives an 8 Ω speaker or a typical buzzer

o Configurable AUD (current) or AUX (voltage) single-ended output drives external audio amplifier

ChipCorder standard features

o High-quality, natural voice and audio reproduction

o 2.4V to 5.5V operating voltage

o 100-year message retention (typical)

o 100,000 record cycles (typical)
