PRELIMINARY DATA SHEET
MOS INTEGRATED CIRCUIT
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 func-
tions, 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 µPD170006AGF-
011 can eliminate one IC chip as compared with existing systems.

and AM (shared with MW and LW), totaling 20

Function
RDSDATA
RDS data input
RDS data input pin. Input data signal from RDS signal
detection block.
Data is read at falling edge of RDS clock.
RDS
RDS signal
input
Input pin to detect RDS signal of RDS station. Used to
prevent synchronization caused by station other than an
RDS station.
Input RDS data is valid when this pin is low.
To synchronize with RDSDATA and RDSCLK only during
auto tuning operation, pull down this pin.
RDSCLK
RDS clock
input
RDS clock input pin. Input clock signal from RDS signal
detection block.
Because the µPD17006AGF-011 does not detect bit syn-
chronization by width of clock signal, input as accurate a
clock as possible.
Band select signal output pins.
When received band is changed by band select key, output

Power inputs pins is lowered to 2.2 V, data can be retained if CE pin (pin

is initialized to initial value. At this time, keep time of
raising voltage from 0 to 4.1 V within 500 ms.
Be sure to connect VDD0 to VDD2 pins to same voltage.
This pin inputs local oscillation output (VCO output) of AM
(MW, LW) band.

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.
Operation
Description
q When MESEL switch of initial setting diode = 1 (shorted with diode)
Preset memory is write-enabled for about 5 seconds when ME key
is pressed. By pressing any of the M1 to M5 keys during
this period, the frequency currently being received is written to preset memory
corresponding to the pressed key.
Frequency cannot be written if the ME key is held down.
When frequency is written, a beep sound is issued for about 40 ms.
Write
q When MESEL switch of initial setting diode = 0 (open)
By pressing any of M1 to M5 keys for about 2 seconds,
frequency currently being received is written to preset memory correspond-
ing to the pressed key.
ME key is invalid.
Same operation is performed when same preset memory key is pressed while
contents of current preset memory are being received.
When frequency is written, a beep sound is issued for about 40 ms.
q When MESEL switch of initial setting diode = 1 (shorted with diode)
By pressing any of the M1 to M5 keys when preset
memory is not write-enabled, contents of preset memory corresponding to
the pressed key are called.
Call q When MESEL switch of initial setting diode = 0 (open)
By pressing any of the M1 to M5 keys and then releasing
the key within seconds, contents of preset memory corresponding to the
pressed key are called. When same preset memory key is called while
contents of preset memory are currently called, a beep sound is issued for
about 40 ms.
