18 SLEEP Sleep
input
If SLEEP
=
Low while V

is being
applied, the device enters Ultra-Low
Current Dissipation mode where memory
only is backed up by stopping crystal
oscillation, PLL, and the CPU.
At that time, V
DD
can be dropped to 0.75
V.
When V
DD
is less than 0.75 V, this
function will be reset. The minimum
frequency 87.5 MHz or 76 MHz will be set
at transmission mode on power on.
To restore from back-up state, set the pin
from Low to High. Turn the radio on at the
same time.
19
IF IN
IF signal input
IF signal input pin for the IF counter to
count the IF signals of the FM band and to
detect the automatic stop positon.
The input frequency is between 0.3 to 12
MHz. A built-in input amp.and C coupling
allow operation at low-level input.
Note: The internal IF amp is operated
whether the IF counter is ON or
OFF, and the noise level will be
increased. Toshiba recommend
connect the pin to GND using the
pin 7 (IF-NOISE) signal at normal
operation.

2. Forced manual switch
Forced manual switchover is done by pin 47
As the figure below shows, when the electronic switch uses a transistor, keep V
CE
(sat, saturated
voltage between the collector and emitter) up to 0.2 V. At this time, if the voltage on pin 47 exceeds 0.2 V
or the current from the pin drops below 30 mA (V
CC
= 3 V typ.), Forced Monaural may not be set.
3. V

The tuner have two voltage supply terminals, V

(for AM, FM IF, MPX stage) and RF V

(for FM RF
stage). Set up the potential diffrence between V

0.4 V (typ.) or less, otherwise there is the
case that this IC doesn't oprete normally.

4. How to control the Divider of FM OSC.
Divider of FM OSC ON/OFF switching is controlled by external pull-up resistor of pin 52.
In case of Divider of FM OSC is used, it is necessary to set up the value of R under 470 W (typ.).
When R is over 470 W, it is feared that Divider is not operating. (At this time, buffer output frequency is
equal to FM OSC frequency.)

6. Setting Constants of External Devices for the Crystal Oscillator Circuit
When determining the required capacitance values of the external components, please send a PCB of the
finalized layout with the ICs mounted on it to the manufacturer of the crystal oscillator for them to test.
If necessary, Toshiba can supply ICs with a range of different parasitic capacitance values on request.
In addition, please use a crystal oscillator with the lowest possible CI value.
A Daishinku K.K. crystal oscillator (with a maximum CI value of 30 kW) was tested with Toshiba's test PCB
(using capacitors of 18 pF and 22 pF).

D6: NG bit
The main microcontroller verifies the D6 bit using the check sum of data sent from the tuner
microcontroller. If D6 is NG, the main microcontroller sets the D6 bit to 1 (NG) and resends it to the tuner
microcontroller within 10 ms. After receiving D6 bit = 1, the tuner microcontroller invalidates D6 = 1 which
was received before the resent D6 = 1. Thus, the resent data are updated 10 ms later.
