Description
This is the LCD controller/driver (µPD16431A) clock
signal output pin.
This is the LCD controller/driver (µPD16431A) serial data
output pin.
For the connection to the µPD16431A, refer to Figure 4-1.
µPD16431A Pin Configuration.
This is the LCD controller/driver (µPD16431A) serial data
input pin.
Connect pull-up resistor externally.
This is the intermediate frequency (IF) input pin for the
FM band.
The inputtable frequency range is 5 to 15 MHz (0.3 VP-P).
Since the pin connects to a built-in AC amplifier, use a
capacitor to cut out the DC portion before inputting.
This pin is used to detect the presence/absence of a
broadcasting station during auto tuning when the initialize
diode is set to “FM SD/IF switch = 1”.
The input frequency condition for determining that there is
a broadcasting station is as follows:

The input frequency range refers to the frequency range
in which input must be made within 10 ms after PLL is
locked.
This is the intermediate frequency (IF) input pin for the
AM band.
The inputtable frequency range is 0.1 to 1.0 MHz (0.3 VP-P).
Since the pin connects to a built-in AC amplifier, please
use a capacitor to cut out the DC portion before inputting.
This pin is used to detect the presence/absence of a
broadcasting station during auto tuning when the initialize
diode is set to “AM SD/IF switch = 1”.
