Description of Key Matrix
2.3.1 Initialization switches
The initialization switches determine the functions of the µPD178024GC-051. Be sure to set these switches.
The following 15 types of initialization switches are available. All these switches are read on power application to
the device, on releasing the standby mode, and on resetting the µPD178024GC-051; they are ignored at all other
times.
To read an initialization switch, the corresponding initialization switch input pin (pin 49 to 56) is tested every 10
ms, and if a specific status of the pin is detected three times, the status of the initialization switch is read. In this way,
chattering is eliminated.

(1) Preset memory scan operation
The contents of each preset memory of the band being received is automatically received for 6
seconds.
If a source other than the preset memory is received when the operation is started, the contents of
the preset memories are sequentially received, starting from M1, for 6 seconds each. If a preset
memory is received, the contents of next preset memory is received for 6 seconds, followed by the
preset memory after next, and so on (for example, while M3 is being received, M4 is received for 6
seconds, followed by M5, M6, and so on), as illustrated below.
M1 → M2 → M3 → M4 → M5 → M6
While the contents of a preset memory are being received for 6 seconds, the preset memory number
is displayed blinking at a frequency of 1 Hz and with a duty factor of 50%. The “CH” indication does
not blink.

(2) Auto store memory
This operation is to search a broadcasting station automatically and write it to a preset memory.
A station is searched in the upward direction starting from the frequency incremented by 1 channel
space from the frequency received when the auto store memory operation was started.
If the auto store memory operation is started while a preset memory is being received, the preset
memory reception status is cleared.
When a station is detected, the frequency of that station is written to a preset memory.
For how to identify detection of a station, refer to “3. RADIO FUNCTIONS”.
During the auto store memory operation, the number of the preset memory to which the frequency of
the station detected last is displayed blinking at a frequency of 1 Hz and with a duty factor of 50%.
If nothing is written to a preset memory, the preset memory number is not displayed.
The auto store memory operation is performed as follows, depending on the on/off status of the local
mode when the operation was started.
Local Mode

frequencies have been searched once, the DX mode is selected and the
search operation continues.
If six or more stations have been detected in the local mode, or if all the
frequencies have been searched in the DX mode, the auto store memory
operation is finished.
If the PSCAN/ASM key is pressed during a search, the auto store
memory operation ends, and the frequency received when the operation
was started is received.
If even one station is detected when the auto store memory operation
ends because six or more stations were detected in the local mode or all

Operation
How the contents of a preset memory are updated differs depending on
the number of stations detected.
(1) If six or more stations were detected in local mode
If six or more stations were detected in local mode, six stations are
selected starting from the highest input level of the S meter, and the
frequencies of the stations are written to the preset memories, starting
from the station with the highest input level and from the lowest preset
memory number.
(2) If less than six stations were detected in the local mode and
stations were later detected in the DX mode, totaling six or more
stations
The stations detected in the DX mode with a high input level of the S
meter are selected so as to total six stations when added to, the stations
detected in the local mode.
However, the stations detected in the local mode are not included in the
stations selected in the DX mode.
The six stations are first written to the preset memories, starting from the
lowest preset memory number and starting from the station with the
highest input level detected in the local mode.
Next, the stations detected in the DX mode but not written to the preset
memories in the local mode are written to the remaining preset memories,
starting from the lowest preset memory number and from the station with
the highest input level.
(3) If less than six stations were detected in the local mode and
stations were later detected in the DX mode, totaling less than
six stations
If the stations detected in the local mode and DX mode are at the same
frequencies, the stations detected in the DX mode are deleted so that the
same frequency is not written to two memories.
Of the six stations, those detected in the local mode are first written to the
preset memories starting from the station with the highest input level and
from the lowest preset memory number.
Next, the stations detected in the DX mode are written to the remaining
preset memories starting from the station with the highest input level and
from the lowest preset memory number.
At this time, the contents of a preset memory to which nothing is written
remain unchanged.

Station Detection
A station is detected during auto tuning (auto seek and auto store memory) if the following two conditions of
receivable frequencies are satisfied:
(1) Station is detected by the S meter signal.
(2) Station is detected by an intermediate frequency.
If detection of an intermediate frequency in the AM band is not selected by initialization switch “DISAMIFC”, the
condition “(2) intermediate frequency” is ignored in detecting stations in the AM band (MW or LW), and only the
condition “(1) S meter signal” is used.
(1) Station detection by S meter signal
Stations are detected or not detected depending on the signal intensity (input voltage) of the S meter signal
input to the SM pin (pin 6) as follows, regardless of the reception bands and reception sensitivity (local/DX).
Input Voltage (VDD = 5.0 V)
Station Detection
128.5 ÷ 256 × VDD or more (2.49 V or more)
Station detected
Less than 128.5 ÷ 256 × VDD (less than 2.49 V)
Station not detected
The S meter signal is identified after the PLL is locked and 20 to 30 ms after the S meter signal has been
stabilized.
For the identification timing of the S meter signal, refer to “12. MUTE OUTPUT TIMING CHART”.
(2) Station detection by intermediate frequency
Stations are detected by measuring the intermediate frequency input to the FMIFC pin (pin 29) while the FM
band is being received, or the intermediate frequency input to the AMIFC pin (pin 28) while the AM band (MW
or LW) is being received.
The input intermediate frequency is measured three times by the internal frequency counter of the
µPD178024-051 for a gate open time of 4 ms. If the result of measurement is in the specific frequency range
more than two times out of three times, a station is detected.
For the range of the intermediate frequencies in which a station is detected, refer to “3.2
Reception
Frequency, Channel Space, Reference Frequency, and Intermediate Frequency”.
For the identification timing of the intermediate frequency, refer to “12. MUTE OUTPUT TIMING CHART”.

5. STANDBY FUNCTIONS
The µPD178024GC-051 can perform a standby operation to reduce the power consumption.
In the standby mode, however, none of the functions, except ejecting the disc, can be used.
The mode is switched between the normal operation mode and standby mode by using the ACC pin (pin 69) and
BATT pin (pin 70).
For the switching timing, refer to “12. MUTE OUTPUT TIMING CHART”.
(1) Standby operation
The ACC and BATT pins are tested every 2 ms five times to suppress chattering.
After chattering has been suppressed, the mode is changed from the normal operation mode to the standby
mode when the ACC or BATT pin goes high.
If the ACC or BATT pin is high since power application, the standby mode is selected on completion of
chattering suppression.
In the standby mode, none of the functions, except ejecting the disc, can be used.
In addition, the LCD panel displays nothing.
The clock is not displayed in the standby mode even if the clock function is specified by using the initialization
switch “NOCLK”.
Internally, however, the clock count continues in the same manner as in the normal operation mode.
In the standby mode, the µPD178024GC-051 performs an intermittent operation by oscillating and stopping
the CPU clock to reduce its own current consumption.
If the clock function is not specified, oscillation of the CPU clock and system clock is completely stopped in
the standby mode.
Consequently, the current consumption of the µPD178024GC-051 is substantially
reduced.
In the standby mode, each pin is placed in the status that lowers the current consumption.
For the pin statuses at this time, refer to “1. PIN FUNCTIONS”.
(2) Operation after releasing standby mode
If the internal falling edge detector of the µPD178024GC-051 detects negative transition of the ACC pin (pin
69) or BATT pin (pin 70), the standby mode is temporarily released, and the ACC and BATT pins are tested.
If both the ACC and BATT pins are high, the standby mode is immediately resumed.
If either of the pins is low, the standby mode is released, and the normal operation mode is set.
When the standby mode has been released, the previous power status and audio source mode selected
before the standby mode was set are restored.
Similarly, the reception frequency of the radio, the contents of the preset memories, the volume values of the
electronic volume, and other functions are restored to the status before the standby mode was set.
If the contents of the internal memory could not be retained because the supply voltage dropped and if the
result of reading the initialization switches differs from before, all the statuses are returned to the default
statuses in the same manner as on power application.
(3) Ejecting disc in standby mode
If the internal falling edge detector of the µPD178024GC-051 detects the negative transition of the EJECT pin
(pin 71), the standby mode is temporarily released and the disc is ejected in the normal mode.
At this time, eject indication is not made on the display.
As soon as the disc has been ejected, the standby mode is resumed.

KEYREQ
Key Scan
Key scan using the µPD16431A is performed as follows:
(1) Detecting a pressed key
The controller judges the state of the KEYREQ pin (pin 6) of the µPD16431A every 20 ms.
When the KEYREQ pin is high, it is assumed that a key is being pressed. Noise elimination (chattering
elimination) based on two consecutive matches is applied.
When noise elimination is performed correctly, the key code is read with serial reception.
Key data is received within 20 ms while a key is held down (the KEYREQ pin is high).
(2) Detecting the release of a key
When a key is released, the level of the KEYREQ pin of the µPD16431A goes from high to low. The pin is
scanned every 20 ms and, if the low level is detected two times in a row, it is judged that the key has been
released.

(1) Input detection timing of rotary commander
Input to the rotary commander is detected as follows:
The RCMD1 (pin 18) and RCMD2 (pin 19) pins are tested every 2 ms two times to suppress chattering. After
chattering has been suppressed, the turn edges are detected as follows:
RCMD1
RCMD2
Right turn edge
Right turn edge
Left turn edge
Left turn edge
However, only the first turn edge of successive turn edges that are within 200 ms is valid.
(2) Function of rotary commander
The rotary commander functions in the same manner as the VOL UP key when it turns clockwise, and as the
VOL DOWN key when it turns counterclockwise. In either case, one turn edge operates the same as one
key input.
However, the operation cannot be repeated as is the case with holding down the
VOL DOWN keys.

(2) Operation based on attachment/detachment of front panel
If the front panel is detached, the power is turned off. It is not turned on until the front panel is attached
(forced power off status).
While the front panel is detached, the FL LED pin (pin 49) outputs a square wave with a frequency of 1 Hz
and a duty factor of 50% to blink an externally connected LED.
In the standby mode, however, this pin always outputs a low level, regardless of the status of the front panel.
Therefore, the LED remains dark.
If the front panel is reattached, the power can be turned on, however the power status immediately after the
front panel has been reattached is always off, regardless of the power status before the panel was detached.

The remote controller keys operate in the same manner as the momentary keys of the µPD178024GC-051.
However, rollover of remote controller keys, including the POWER key, is invalid (no key input is detected).
The clock cannot be adjusted by remote controller keys by pressing the MAN UP/SEEK UP ( NEXT/FF ) or
MAN DWN/SEEK DWN ( PREV/REW ) key after the DISP key.

11. ELECTRONIC VOLUME CONTROL
11.1 Electronic Volume Functions
The µPD178024GC-051 uses an electronic volume IC (TDA7313) to control audio output and for audio selection.
The following electronic volume functions are available.
(1) Setting gain of electronic volume IC
The gain of the electronic volume IC is set to 0 dB.
(2) Adjusting volume
The volume can be adjusted in each of the following modes:
Mode
Function
Adjustment
Range
Default Value on Power Application
Volume
Adjusts volume of main volume.
00 to 63
28
Bass
Adjusts volume of bass (low-frequency region).
−6 to +6
00 (no bass compensation)
Treble
Adjusts volume of treble (high-frequency region).
−6 to +6
00 (no treble compensation)
Balance
Adjusts volume balance between left and right.
R31 to L31
00 (center position between left and right)
Fader
Adjusts volume balance between front and rear
F31 to R31
00 (center position between front and rear)
However, the fader cannot be adjusted if the fader adjustment function is not specified by the initialization
switch “FADSEL”.
When equalize processing is performed by the electronic volume and when the equalizer mode is other than
“FLAT”, bass and treble cannot be adjusted.
For equalizer processing by the electronic volume, refer to “(4) Equalizer processing by electronic volume”.
To adjust the volume, select an adjustment mode by using the VOL SEL/VOL CLR key, and make an
adjustment by using the VOL UP and VOL DWN keys.
For the specific adjustment method, refer to the description of each of the above keys.
On power application, the volume value in each mode is set to the default value.
On power application and on releasing the standby mode, the main volume value set at that time is returned
to the default value if it is greater than the default value, or is retained if it is less than the default value.
At this time, the volume values in the bass, treble, balance, and fader modes are retained regardless of their
values.
For the correspondence between the displayed volume values and the set values of the electronic volume IC,
refer to “11.2 Electronic Volume IC (TDA7313) Set Values”.
Data Sheet U14608EJ1V0DS00
75
µPD178024GC-051
(3) Loudness control
Each time the LOUD key is pressed, loudness is turned on or off.
When loudness is on, the LOUD pin (pin 39) outputs a low level, and the loudness of the electronic volume IC
is turned on.
If the loudness of the electronic volume IC is on, the gain of the electronic volume IC is amplified by +7.5 dB.
(4) Equalizer processing by electronic volume IC
If it is specified by the initialization switch “EQICSEL” that the equalizer is not used, equalizer processing by
the electronic volume IC is performed.
Equalizer processing by electronic volume IC is performed by setting the gain of the bass and treble in an
equalizer mode.
At this time, the bass adjustment mode and treble adjustment mode are skipped when an electronic volume
mode is selected by using the VOL SEL key in an equalizer mode other than “FLAT”. Therefore, bass and
treble cannot be adjusted.
Bass and treble are adjusted as follows in each equalizer mode.
Equalizer Mode
FLAT
ROCK
CLASSIC
POP

Treble

Bass

(5) Mute setting of electronic volume
In the mute-on status, the MUTE pin outputs a low level, and the electronic volume IC is muted.
For the mute value of the electronic volume IC, refer to “11.2 Electronic Volume IC (TDA7313) Set Values”.

Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on
the verge of suffering physical damage, and therefore the product must be used under
conditions that ensure that the absolute maximum ratings are not exceeded.

Notes 1. The first clock pulse is generated at the start condition after this period.
2. The device needs to internally supply a hold time of at least 300 ns for the SDA0 signal to fill the
undefined area at the falling edge of the SCL0 (VIHmin. of the SCL0 signal).
3. Unless the device extends the low hold time (tLOW) of the SCL0 signal, it is necessary to fill only the
maximum data hold time (tHD : DAT).

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note:
Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. Steps must be taken to stop generation of static electricity
as much as possible, and quickly dissipate it once, when it has occurred. Environmental control
must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using
insulators that easily build static electricity. Semiconductor devices must be stored and transported
in an anti-static container, static shielding bag or conductive material. All test and measurement
tools including work bench and floor should be grounded. The operator should be grounded using
wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need
to be taken for PW boards with semiconductor devices on it.
2
HANDLING OF UNUSED INPUT PINS FOR CMOS
Note:
No connection for CMOS device inputs can be cause of malfunction. If no connection is provided
to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence
causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels
of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused
pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of
being an output pin. All handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note:
Power-on does not necessarily define initial status of MOS device. Production process of MOS
does not define the initial operation status of the device. Immediately after the power source is
turned ON, the devices with reset function have not yet been initialized. Hence, power-on does
not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the
reset signal is received. Reset operation must be executed immediately after power-on for devices
having reset function.
