Preliminary W91030B
Publication Release Date: March 2000
- 5 - Revision A1
SYSTEM DIAGRAM
The W91030B 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 W91030B 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.
