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 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 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

notinitializeduntiltheresetsignalisreceived. Resetoperationmustbeexecutedimmediately

after power-on for devices having reset function.

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

applicationsofa device depend on its quality grade, asindicatedbelow. Customersmustcheckthequality

grade of each device before using it in a particular application.

Standard: Computers,officeequipment,communicationsequipment,testandmeasurementequipment,

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-

disastersystems,anti-crimesystems,safetyequipmentandmedicalequipment(notspecifically

designed for life support)

Specific: Aircrafts,aerospace equipment, submersiblerepeaters,nuclearreactor 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.
