NOTES FOR CMOS DEVICES

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.

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

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.

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.

Descriptions of circuits, software and other related information in this document are provided for

illustrative purposes in semiconductor product operation and application examples. The incorporation

of these circuits, software and information in the design of customer's equipment shall be done

under the full responsibility of customer. NEC Electronics no responsibility for any losses incurred by

customers or third parties arising from the use of these circuits, software and information.

While NEC Electronics endeavors to enhance the quality, reliability and safety of NEC Electronics

products, customers agree and acknowledge that the possibility of defects thereof cannot be eliminated

entirely. To minimize risks of damage to property or injury (including death) to persons arising from

defects in NEC Electronics products, customers must incorporate sufficient safety measures in their

design, such as redundancy, fire-containment and anti-failure features.

NEC Electronics products are classified into the following three quality grades: “Standard”, “Special”

and “Specific”.

•

The "Specific" quality grade applies only to NEC Electronics products developed based on a customer-

designated “quality assurance program” for a specific application. The recommended applications of

NEC Electronics product depend on its quality grade, as indicated below. Customers must check the

quality grade of each NEC Electronics product 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.

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).

Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems,

life support systems and medical equipment for life support, etc.

"Special":

"Specific":

The quality grade of NEC Electronics products is “Standard” unless otherwise expressly specified in

NEC Electronics data sheets or data books, etc. If customers wish to use NEC Electronics products in

applications not intended by NEC Electronics, they must contact NEC Electronics sales representative

in advance to determine NEC Electronics 's willingness to support a given application.

Notes:

" NEC Electronics" as used in this statement means NEC Electronics Corporation and

also includes its majority-owned subsidiaries.

" NEC Electronics products" means any product developed or manufactured by or for

NEC Electronics (as defined above).
