µ PD17006AGF-011
4-BIT SINGLE-CHIP MICROCONTROLLER WITH PRESCALER,
PLL FREQUENCY SYNTHESIZER, AND IF COUNTER
FOR AUTOMOBILE FM, MW, AND LW RADIOS
DESCRIPTION
The µPD17006AGF-011 is a 4-bit CMOS microcontroller for digital tuning and can receive European FM,
MW, and LW bands. It contains a prescaler (150 MHz MAX.), PLL frequency synthesizer, and IF counter.
This microcontroller supports European Radio Data System (RDS) and implements various RDS functions, so that it can configure with a single chip a high-performance FM, MW, or LW tuner such as that for
luxury automobile stereo systems.
In addition, an RDS decoder is realized as a software library, so that the system using the µPD170006AGF011 can eliminate one IC chip as compared with existing systems.

Station selection function
(1) Manual tuning
Type
Description
Manual up
Manual down
Increases or decreases frequency by 1 step each time key is pressed. If key is held down
for 0.5 second or longer, frequency is increased/decreased rapidly until key is released.
(2) Auto tuning
Type
Seek up
Seek down
Description
Searches station in up or down direction. When station is found, its frequency is held
(seek operation is performed in 100-kHz steps in FM band). Only RDS stations are
searched for in RDS mode. Only traffic information station is searched for in TP/SK
mode.
(3) Preset memory
Five stations can be stored for each of the four bands (FM1, FM2, FM3, and AM). Therefore, up to 20
stations can be stored. The AM band is shared with MW and LW bands.
(4) Preset memory scan
The contents of the FM1, FM2, FM3, and AM preset memories can be received independently for about
5 seconds each.
(5) Auto store memory
Stations can be searched starting from the minimum frequency. When stations are found, they are
written to the preset memories starting from the one with the highest signal meter level. The stations
are then sorted in the order of frequency.
(6) Last channel memory
One station of last channel memory is provided independently for each of FM1, FM2, FM3, and AM.
(7) Auto retune
If the SD signal cannot be detected for about 20 seconds while a station is being received, tuning is
automatically started.

RDS function
(1) Broadcasting station display
The name of the broadcasting station currently being received is displayed by using a PS code.
(2) AF operation
An AF list of up to 25 stations can be loaded, with METHOD A and METHOD B supported. Loading of
AFs of other stations by EON is also supported.
(3) Traffic information station selection
TA and TP bits are detected in TP/SK standby status and a traffic information station is selected. This
function supports EON.
(4) Time adjustment
The internal timer is adjusted by using CT code.
(5) Alarm
When the PTY alarm code (=31) is received, the sound is changed to the radio.
(6) RDS memories
Up to 22 types of PI codes can be stored in the RDS memories. The memory of each PI code stores eight
stations from the corresponding AF lists.
(7) Broadcasting program identification information
By using PTY codes 0 to 15, the name of the broadcasting program currently being received can be
displayed. In addition, searching by using the displayed program name can be performed.
Timer function
(1) 12-hour display (with “
” and “

Functional Description
(1) Normal mode
These keys operate as preset memory call and write keys in tuner mode.
One key can be independently assigned to preset memories storing five stations in each of the
FM1, FM2, FM3, and AM bands, totaling 20 stations.
If a station written to preset memory is an FM-band RDS broadcasting station, the PI code of that
station is also written at the same time.
If a station is called for which RDS broadcasting is stored, AF selection is performed by using
the AF list of preset 8 stations. If RDS broadcasting still cannot be received, a PI seek operation
is performed in the up direction. If SEEK/MAN DOWN key is pressed during this seek operation, a
normal seek operation is performed and continued until a station is found. To stop the seek
operation, press the SEEK/MAN UP key.
During a time or PS display, the frequency display is switched to.

Auto store memory
Searches broadcasting stations in DX mode in range from lower limit (minimum frequency) to
upper limit (maximum frequency) of currently received band, writes preset number of stations
starting from one with highest signal meter level, and then sorts stations in order of frequency.
In this case, if RDS broadcasting is received in FM band, the PI code of that station is also recorded
at the same time.
If stations having same PI codes are found, only station with highest signal meter level is written.
After operation, M1 is received. If no station is found, frequency at which operation was started
is resumed.
(a) If stations have been written to all the keys M1 through M5 and then another station is found
If signal meter level of that station is lower than signal meter level of station written to M5,
selection operation continues. If signal meter level is higher, that station is written to M5,
stations written to M1 to M5 are sorted again starting from highest signal meter level, and then
selection operation continues.
If stations with same signal meter level are found, it is assumed that signal meter level of
station found first is higher.
(b) If number of stations falls short of number of preset stations
Stations found so far are sequentially written to preset memory starting from M1, and found
stations are sorted in order of frequency.
Contents of remaining preset memory before auto store memory operation was performed
are preserved.

4.1.1 PI (Program Identification)
This RDS data is used to identify broadcasting programs.
After the tuning operation has been completed, the same PI code is input two times or more, so that RDS
data having the same PI code is decoded.
The PI counter is incremented up to eight counts.
If RDS data having different PI codes are input, the PI counter is decremented, and those RDS data are
not decoded, unless they are TP or TA. When the PI counter has been decremented to zero, a differing PI
code is judged to be the correct PI code, the PI counter is incremented, and when the PI counter become
decremented two or more, the RDS data are decoded.
Fig. 4-1 shows the operation of the PI counter.

4.1.2 PS (Program Service Name)
This data is used for PS display on the LCD panel.
By inputting the same PS data two times, the PS data is determined, and is displayed on the LCD panel.
If the tuned station is an RDS broadcasting station when the tuning operation has been completed, PS
display is performed at the point when the PS data has been determined (after about 3 seconds).
Once the PS data has been input, the already input PS data is displayed even if no more PS data can be
input.
4.1.3 PTY (Program Type)
This data is used to identify alarms and to display program types.
By inputting an alarm during RDS broadcasting station reception, the radio mode is set if the tape/CD
mode is set, and the TA/DK pin (pin 25) is made low.
A program type can be displayed and searched for by pressing the
the description of the
PTY
key (for details, refer to

This data is used as an alternative frequency list.
(1) Inputting an AF list
Up to 25 AF lists can be input. If more than 25 AF lists are sent, they are overwritten from the top of
the list.
The AF function supports both METHOD A and METHOD B.
If lists are sent by METHOD B in pairs and in descending order, the following processing is performed:
(a) If the area cover code of the PI code of the station currently received is ‘1’ to ‘3’, the pair in
descending order is included in the list.
(b) Other than above, the pair in descending order is not included in the list.

(2) AF operation
There are two operation procedures for AFs: AF operation 1 and AF operation 2.
AF operations 1 and 2 are performed as follows (the condition under which AF operation 1 is performed
is in FM band and when an RDS station is called):
●
AF operation 1
• At CE reset
• When band is changed
• When preset memory is read
• When tuner is selected by sound selector (except while tuner is performing seek operation)
●
AF operation 2
• When electric field intensity of broadcasting currently received drops below a specific level during
RDS station reception
The AF operations are described below.
(a) AF operation 1
AF selection is performed by the following procedure if the FM band is selected, and the station
called was an RDS station, when CE reset is effected, when the band is changed, when the preset
memory is read, or when the tuner is selected by the sound selector (except while the tuner is
performing a seek operation).
1
The AF memories (of up to 8 stations) corresponding to the called RDS station are sorted in order
of frequency.
2
The SD pin is checked starting from the highest frequency. The signal meter level at which the
broadcasting station is detected is stored.
3
AF selection is performed starting from the highest signal meter level, based on the detection
result in 2 .
4
If an RDS station is detected as a result of AF selection, the PI code is checked.
At this time, the PI code is checked as follows:
When the region mode is selected because initial setting diode REGEN = 1 and by the
REGION
key, coincidence of a 12-bit PI code except the area cover code of the PI code is
detected; otherwise, coincidence of a 16-bit PI code is detected.
When detection of coincidence of this PI code is successful, the AF operation is completed, and
an RDS station is received.
5
If AF selection fails in 4 , the RDS mode is checked. A PI search operation is performed when
the RDS mode is selected (for the PI search operation, refer to (3) PI search operation).
When the RDS mode is not selected, the station received before AF selection is retained.
If a preset memory number is being displayed at this time, it is extinguished.
(b) AF operation 2
This operation is valid when the RDS mode is selected.
It denotes an AF operation that is performed when receiving an RDS station and the electric field
intensity of the station currently being received drops below a specific level.
The start condition for AF operation 2 is as follows:
44
µPD17006AGF-011
●
AF operation 2 start condition
The electric field intensity of the broadcast currently being received is input from the S-METER
pin (pin 5), and the data error level is input from S-QUALITY pin (pin 6). These values are
converted into digital values, which are classified as follows:
A/D value of signal meter
A/D value of signal quality
L ≤ 48H < M ≤ 80H < H
L ≤ 50H < H
Caution When the signal quality is not used, fix the S-QUALITY pin (pin 6) to the low level.
Depending on the combination of the classified signal meter and signal quality values, the
following AF operation is performed:
• When initial setting diode DEV.SEL = 0 (DEV.LEVEL is ignored)

seconds or more has passed since the previous AF selection operation.
(c) AF operation 2-1
• When initial setting diode AFSEL = 0
The AF of each station is changed every 5 seconds. If changing the AF fails, the original station
is retained.
• When initial setting diode AFSEL = 1
The AF of each station is changed at time intervals of 1 to 30 seconds generated at random.
If changing the AF fails, the original station is retained.
45
µPD17006AGF-011
(d) AF operation 2-2
• When initial setting diode AFSEL = 0
AF is selected by the following procedure:
1
The AF list currently received (up to 25 stations) is sorted in order of frequency.
2
The SD pin is checked from the highest frequency, and up to eight stations of signal meter
levels are stored when a station is detected.
3
Based on the result in 2 , the AF is selected starting from the station with the highest signal
4
If an RDS station is detected in the course of AF selection, the PI code is checked.
meter level.
At this time, the PI code is checked as follows:
When the region mode is selected because the initial setting diode REGEN = 1 and the
REGION
key is asserted, coincidence of the 12-bit PI code excluding the area cover
code of the PI code is detected; otherwise, coincidence of a 16-bit PI code is detected.
The AF operation is completed when detection of coincidence of the PI code is successful, and
an RDS station is received.
5
If AF selection fails in 4 , the station before AF selection was performed is retained.
• When initial setting diode AFSEL = 1
The AF of each station is changed every 5 seconds. If changing the AF fails, the original station
is retained.
(3) PI search operation
If AF selection fails when AF operation 1 has been performed, and RDS mode is set, a PI search operation
is performed by the following procedure:
1
Stations are searched in the up direction in 100-kHz steps to make a pass through the band, starting
from the frequency received before failure of AF selection.
2
A station is detected. If it is not an RDS station, proceed to the next step. If it is an RDS station, the
PI code is checked.
The PI code is checked as follows:
When the region mode is selected because the initial setting diode REGEN = 1 and the
REGION
key is asserted, coincidence of the 12-bit PI code excluding the area cover code of the PI code
is detected; otherwise, coincidence of a 16-bit PI code is detected.
3
If detection of coincidence of the PI code is successful in 2 , the AF operation is completed, and the
station is received.
4
If detection of coincidence of the PI code fails in 2 , and if coincidence of the PI code is not detected
after the PI search is performed, passing through the band, the frequency before the PI search is
retained, and the AF operation is completed.
4.1.5 EON (Enhanced Other Network)
The EON information sent as block 3 of group type 14A uses the AF list of the network of the other station
and mapped FM frequency.
Group type 14A and data are input by the following procedure:
46
µPD17006AGF-011
1
The PI code same as the PI code stored in block 4 of the data sent by 14A is searched from the pool
memory.
2
If the PI code that coincides with the PI code stored in block 4 is found, the next frequency of block
3 of the data sent by 14A is registered in the AF list attached to that PI code.
●
AF list sent by Usage Code 4
●
Mapped FM frequency sent by Usage Code 5-8
Remark The frequency is registered in 2 as follows:
●
Registering an AF list sent by Usage Code 4
Up to eight stations are input to a work area.
If the PI code sent by block 4 of 14A is changed, or if the receive frequency is changed,
the data in the work area is updated to accept the AF list of the PI code that coincides.
If a PI code that coincides is not found, the work area is updated to be a new pool memory.
If there is no vacant pool memory, pool memories are overwritten starting from the oldest
one that is not registered to preset memory.
●
Registering an AF list sent by Usage Codes 5 to 8
(a) If a PI code that coincides already exists in pool memory
The AF list in the pool memory is directly updated (refer to the figure below).
PI code
Usage
Code 5
Usage
Code 6

Code 7

AF8
The storage positions corresponding to Usage Codes 5 to 8 are predetermined as
shown in the above figure. AF1 takes the highest priority for AF selection.
In this case, even if the AF list in a pool memory has been already registered, the pool
memory is overwritten when Usage Codes 5 to 8 are input.
(b) If the PI code that coincides is not in pool memory
In this case, the same assumption is made as when a PI code that coincides is missing
in the case of Usage Code 4.
For traffic information interrupt operation of a station other than the received station, refer to 4.1.6 TP,
TA.
4.1.6 TP (Traffic Program Identification), TA (Traffic Announcement Identification)
These data are used to identify a traffic information station or traffic information announcement.
A traffic information station is identified as follows:
• When TP = 1
• When TP = 0 and TA = 1
47
µPD17006AGF-011
A traffic information announcement is identified as follows:
• When broadcasting of TP = 1
It is judged that traffic information is received when TA = 1.
• When TP = 0 and TA = 1
Traffic information is provided by the station whose PI is included in the group type 14B that was sent.
Traffic information is selected as follows:
• When TP = 1
When TA = 1, the TA/DK pin (pin 25) outputs low level. If tape/CD mode is set at this time, radio mode
is set.
When TA = 0, the TA/DK pin outputs high level, and the original mode is set.
• When TP = 0 and TA = 1
Group type 14B is sent. When the network TA of the other station = 1, and the station given by PI
indicated in block 4 is stored in a preset or pool memory, all the AF lists are checked. The station with
the highest signal meter level from the stations whose PI coincide is selected and received.
If no station whose PI coincides is found, a PI search operation is performed (refer to 4.1.4 (3) PI search
operation).
In radio mode, mute is canceled when a new broadcast is selected, and that broadcast is received. The
TP and TA of that broadcast are then checked. If both TP and TA do not become 1 within 4 seconds, the
original broadcast is received. In this case, selection by 14B for that PI is not made for 4 seconds.
When both TP and TA become 1, the TA/DK pin outputs the low level.
In the tape/CD mode, the TP and TA of the broadcast that has been selected are checked. If both TP and
TA do not become 1 within 4 seconds, the original broadcast is received.
If both TP and TA become 1, TA/DK pin outputs low level, and radio mode is set.
In both the radio and tape/CD modes, if TP = 1 and TA = 0 later, the TA/DK pin outputs high level and the
original station is received.
At this time, even if 14B is received, if TA of the network of the other station = 0, the reception mode
continues.
If the RDS signal is no longer received after the new broadcast is selected, the original broadcast is
received.
●
Alarm when a traffic information station is no longer received
(1) If 30 seconds have passed since a received traffic information station is no longer judged as such
(except when traffic information from another station is received by EON)
• In radio mode
: The SK mute pin (pin 23) outputs low level, and an alarm is
output (from pin 28) 3 seconds later.
• In a mode other than radio mode : A Traffic information station is searched for throughout the
band.
(2) If the frequency is changed while ALARM (pin 28) is being output (if the newly selected broadcast
is not traffic information)
When the alarm stops temporarily and mute (pin 24) is canceled, SK mute is output overlapped with
that mute, and alarm is output 3 seconds later.
48
µPD17006AGF-011
(3) If CE goes high and the received station is judged not to be a traffic information station, and a traffic
information station is not detected 3 seconds after mute has been canceled
An operation same as (1) above is performed.
(4) If another mode is selected during alarm output
Operation the same as in a mode other than radio mode in (1) above is performed.
(5) When radio mode is set while a seek operation is being performed in a mode other than radio mode
The seek up operation continues, and operation the same as in a mode other than radio mode in (1)
above is performed.
(6) When traffic information mode is canceled while a seek up operation is being performed in a mode
other than radio mode
The seek up operation continues, and the normal auto tuning operation is performed (only RDS
stations are received when RDS mode is selected).
●
Searching for a traffic information station
When auto tuning is performed in the traffic information mode, a judgment is made 400 to 500 ms after
auto tuning is temporarily stopped by SD as to whether the received station is a traffic information
station, and only the traffic information station is stopped.
The above traffic information operations are performed by using RDS mode even when RDS mode is not
selected.
4.1.7 CT (Clock-Time and Data)
This data is used to adjust the timer.
The time broadcast is the Coordinated Universal Time (UTC) recommended by the CCIR. It is therefore
converted to local time and used as timer data.
By inputting a time announcement, the value of the internal timer of the µPD17006AGF-011 is adjusted
to the value of local time.
When the CTADJ switch of the initial setting diode = 1 (shorted with diode), the time can be always
adjusted by inputting time announcement information. Each time the time is adjusted, the seconds are
cleared to 0.
Note that an adjustment can be made from time announcement information even while the timer is being
adjusted by the timer being adjustment key.
Whether time adjustment is made by using the time adjustment data is set by the NOCLK, CTSRT, and
CTADJ switches of the initial setting diode.

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
device 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 VDD 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.
