10 / 88 page  ISD5100 – SERIES - 10 - interface. These are the RAC timing pin and the INT pin for interrupts to the controller. Communications with all the internal registers of any operations are through the serial bus, as well as digital memory Read and Write operations. 7.1.5. Programming The ISD5100 Series are also ideal for playback-only applications, where single or multiple messages may be played back when desired. Playback is controlled through the I 2C interface. Once the desired message configuration is created, duplicates can easily be generated via a third-party programmer. For more information on available application tools and programmers, please see the Winbond web site at www.winbond-usa.com 7.2. FUNCTIONAL DETAILS The ISD5100 Series are single chip solutions for analog and digital data storage. The array can be divided between analog and digital storage according to user’s choice, when the device is configured. The below block diagram shows that the ISD5116 device can be easily designed into a telephone answering machine (TAD). Both Mic inputs transmit the voice input signal from the microphone to perform OGM recording, as well as to record the speech during phone conversation (simplex). When the TAD is activated, the voice of the other party from the phone line feeds into the AUX IN, and is recorded into the ISD5116 device. Then the new messge is usually indicated with blinking new message LED. Hence, during playback, the recorded message is sent out to speaker with volume control. Two I 2C pins are used for all communications between the ChipCorder and the microcontroller for analog and/or digital storage, and the two outputs, INT and RAC are feedback to microcontroller for message management. For duplex recording, speech from Mic inputs and message from received path can be directly recorded into the array simultaneously, then playback afterwards. In addition, for speaker phone Speaker ISD5116 SP+ SP- MIC+ MIC- Microcontroller I 2C (INT, RAC) NV Memory Display & Push buttons AUX IN AUX OUT DAA Phone Line DTMF Detect, Caller ID ANA OUT+ |
