Multimessage ChipCorder suits direct trigger apps

Winbond Electronics Corp. America has introduced a new multi-message ChipCorder with up to eight direct triggers for the automotive, industrial and consumer markets.

ISD1900 provides high quality voice in a single chip, reducing the BOM cost and shortening time to market. It is a suited solution for applications with multiple record and playback buttons, with each button triggering a different message.

Current voice solutions providing multiple messages of similar durations often require an MCU with significant coding efforts. ISD1900 eliminates both the need for an MCU and code programming. Thus, engineers can quickly and easily add voice functionality into their applications and have their product ready to launch within a short period of time and at a lower BOM cost.

Key features of this series include wider operating voltage (2.4-5.5V), higher sampling frequency (4-12kHz), user-selectable durations from 10.6s to over 2mins and feed-through control that takes analog signals and feeds it to the speaker outputs for voice broadcasting and monitoring. The device also boasts

dual operating modes: first is multiple messages with variable duration triggered by start and end address inputs and the other is obtaining up to eight messages of similar duration triggered by each individual button.

ISD1900 is designed for easy migration from older ChipCorder series such as ISD1400 and ISD2500. Customers can preserve the functionalities of their current designs with minor board changes needed, said Winbond.

ISD1900 is available in a 28-pin SOIC Pb-free package. Die form is available under the ISD14B00 series.
