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 (V^DD= 1.8 to 3.6 V), the µPD17071GB-012

is ideal for creating a compact portable clock radio and radio cassette recorder.

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 V^DDor 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. Produc-

tion 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 imme-

diately after power-on for devices having reset function.

Purchase of NEC I²C components conveys a license under the Philips I²C Patent Rights to use these components

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.

The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.

If customers intend to use NEC devices for applications other than those specified for Standard quality grade,

they should contact an NEC sales representative in advance.

Anti-radioactive design is not implemented in this product.
