ISD1610BPYI

The preliminary publication release date of the ISD1600B Series Single-Message Single-Chip Voice Record & Playback Devices with vAlert Option was Jan. 23, 2007.

The ISD1600B Series devices offer the vAlert (voiceAlert) feature as a special option. With vAlert, the IC can strobe an external LED to indicate the presence of a new message. The LED blinks slowly after recording to signal a new message, and once playback is done, the LED stops blinking and returns to normal operation. This feature provides a visual indicator for new messages in single-message applications.

The range of voice record and playback duration for the ISD1600B Series devices is from 6.6 seconds to 40 seconds. The duration can be adjusted based on the specific device within this range. The sampling frequency and duration are determined by an external resistor connected to the Rosc pin.
