PIN No. Symbol Pin Name Function and Operation If SLEEP = Low while VDD 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, VDD can be dropped to 0.75 V. When VDD 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. 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. 19 IF IN IF signal input Note: The internal IF amp is operated whether the IF counter is ON or OFF, and the noise level will be increased.

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 VCE (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 (VCC = 3 V typ.), Forced Monaural may not be set.

3. VCC line
The tuner have two voltage supply terminals, VCC (for AM, FM IF, MPX stage) and RF VCC (for FM RF stage). Set up the potential diffrence between VCC and RF VCC 0.4 V (typ.) or less, otherwise there is the case that this IC doesn't oprete normally.

1/1 or 1/16
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.)

Note 1: The 1/16 FM OSC is used to set the combination of the tuner and PLL. When combining the tuner and PLL using the IC, do not select the 1/1 FM OSC.

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.

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.
