Preliminary W91031
Publication Release Date: August 2000
- 5 - Revision A1
SYSTEM DIAGRAM
The W91031 device applications include telephone systems which have caller ID features and which
can display the calling message on an LCD display. Figure 5 shows the system diagram. It illustrates
how to use the chip to connect between the tip/ring and the microcontroller in the telephone system.
The ring signal is detected by the W91031 device and then an interrupt sent to the microcontroller.
The ring detected signal will also be directed to the ringer circuit. The data can be decoded by the
microcontroller and displayed on the LCD display. The DTMF ACK signal can also be generated by
the DTMF generator if a call on waiting is performed. Other functions are the same as the telephone
set.
