PRELIMINARY DATA SHEET
MOS INTEGRATED CIRCUIT
µPD17071GB-012
4-BIT SINGLE-CHIP MICROCONTROLLER WITH PLL FREQUENCY
SYNTHESIZER CONTROLLER FOR PORTABLE FM/AM RADIO AND TV
DESCRIPTION
The µPD17071GB-012 is a CMOS microcontroller with an on-chip PLL frequency synthesizer for receiving
international FM and AM and Japanese TV broadcasting.
In addition, because it includes a prescaler (230 MHz MAX.), IF counter, and LCD controller/driver, it constitutes
a high-performance, multi-function FM, AM, or TV tuner on a single chip.
Housed in a 56-pin QFP and driven by two dry cells at a low voltage (VDD = 1.8 to 3.6 V), the µPD17071GB-012
is ideal for creating a compact portable clock radio and radio cassette recorder.

SD signal input
This pin inputs an SD (Station Detector) signal.
When “Europe 1” or “Europe 2” is selected as the destination region,
this pin can be also used to input setting of a channel space in an
AM band.
Input
(1) Setting of channel space in AM band for “Europe 1” and
“Europe 2” (9 k/10k)
This setting is valid only when “Europe 1” or “Europe 2” is selected
as the destination region.
The setting is read only on power application (power-ON reset), or
when the signal input to the CE pin (pin 50) goes high (CE reset);
otherwise, it is ignored.
Input a signal to this pin as follows:
• High level: Channel space 9 kHz
• Low level: Channel space 10 kHz
Note that the setting of this pin is invalid when initialization diode
switch SD_IF = 1, and the channel space is 9 kHz.
(2) Input of SD signal (SD)
When a station has been detected this is identified by the signal
input to this pin and the frequency counter when initialization diode
switch SD_IF = 1.
Input a high level to this pin when a station is detected.
However, a signal input for less than 32 ms is invalid.

intermediate
frequency input
This pin inputs an intermediate frequency (IF) in an FM or AM band.
The signal input to this pin is used to identify a station.
When initialization diode switch SD_IF = 1, however, the signal input to
this pin and the signal input to the SD pin (pin 16) are used to identify
a station.
The range of the input frequency in which detection of a station is
identified is as follows:
Band
Input frequency range <1> Input frequency range <2>
FM
10.7 MHz ± 20 kHz
AM
450 kHz ± 1 kHz
459/460 kHz ± 1 kHz

When the input to the KEYLOCK pin is low, the keys can also be locked by a key operation.
(1) Locking keys by input to KEYLOCK pin (pin 14)
The momentary keys can be locked by input to the KEYLOCK pin.
The operation of the momentary keys can be manipulated as follows by the pin input.
• High-level input
Locks keys and invalidates all key operations.
Also invalidates the key operation to unlock the keys.
• Low-level input
All the keys perform normally when the keys are pressed.
At this time, the keys can be locked or unlocked by a key operation.
(2) Locking keys by key operation
The keys can be locked or unlocked by a key operation when the input to the KEYLOCK pin (pin 14) is low. If
the input to the KEYLOCK pin is high, however, the locked keys cannot be unlocked by a key operation.
The momentary keys are locked by performing the following key lock operation.
• When the keys are locked, they are unlocked when the key lock operation is performed again.
• When the keys are locked, all key operations other than that to unlock the key is invalid.
The following key lock operation is performed, depending on initialization.
• When initialization diode switch STOPSEL = 0
Press the
STOP
key and then the
MODE
key twice.
• When initialization diode switch STOPSEL =1
Press the ALARM key and then the
MODE
key twice.

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.

in an I2C system, provided that the system conforms to the I2C Standard Specification as defined by Philips.
No part of this document may be copied or reproduced in any form or by any means without the prior written
consent of NEC Corporation. NEC Corporation assumes no responsibility for any errors which may appear in
this document.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property
rights of third parties by or arising from use of a device described herein or any other liability arising from use
of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other
intellectual property rights of NEC Corporation or others.
While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a
customer designated "quality assurance program" for a specific application. The recommended applications of
a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device
before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
