Product specification
Self Tuned Radio (STR)
TEA5762
To ensure that the search function operates correctly
under all conditions the following search sequence must
be applied:
Store the current frequency in the memory
Issue the search command
Wait for data valid and read the new frequency
If the new frequency is the same as the stored
frequency, issue a pre-set step (e.g. 50 kHz) and start
the search sequence again.
Description of the bus
The TEA5762 radio has a bus which consists of three
wires, as shown in Table 1.

These three signals, together with the mono/stereo pin
(MO/ST; pin 24), communicate with the microcontroller.
The mono/stereo indicator has two functions, which are
controlled by the BUS-CLOCK, as shown in Table 2.

Bus-clock functions
TheTEA5762hasa25-bitshiftregister; see Table 3foran
explanation of the shift register bits.
If in search mode no transmitter can be found, all
frequency bits of the shift register are set to logic 0.
The bus protocol is depicted in Figs 3 and 4.
