The range of voice record and playback duration for the ISD1600B Series devices is from 6.6 seconds to 40 seconds, depending on the specific device. The duration can be adjusted by an external resistor connected to the Rosc pin, with sampling frequencies ranging from 4 kHz to 12 kHz.

The ISD1600B Series devices offer the special feature of vAlert (voiceAlert) option, which can be used as a new message indicator. With vAlert, the IC strobes an external LED to indicate the presence of a new message. The LED blinks slowly after a record, indicating the existence of a new message, and once playback is performed, the LED will not blink again and resume to normal operating conditions. This feature provides a convenient way to notify users of new messages in single-message applications.

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