12 APPLICATION INFORMATION
Figure 19 shows a typical portable/personal radio system
application which uses the device in conjunction with the
Self Tuned Radio (STR) TEA5757. This application
provides the following functions:
Scanning the keypad
Transfer of commands and information to and from the
rest of the radio system
Display of information on a LCD
Storage of preset frequencies
Real Time Clock (not always required).
Control between the TEA5757 and the microcontroller is
performed by a 4 line interface bus.
The advantage of the TEA5757 is that it works
independently from the microcontroller, e.g. once tuned to
a station, the microcontroller could be removed and the
tuner stays tuned.
The system is designed such that the microcontroller is
switched to Power-down mode when no actions are
required; this increases the lifetime of the batteries.
The microcontroller is activated by an interrupt, e.g. when
a key on the keyboard is pressed, or by the 1 second timer
(updating the real-time clock function). After the
appropriate actions are taken the microcontroller will enter
the Power-down mode again.
