Cautions 1. During address transition, at least one of pins /CE1, CE2, /WE should be inactivated.  
2. When I/O pins are in the output state, do not apply to the I/O pins signals that are  
opposite in phase with output signals.  
Remarks 1. Write operation is done during the overlap time of a low level /CE1, /WE and a high level CE2.  
2. If /CE1 changes to low level at the same time or after the change of /WE to low level, or if CE2  
changes to high level at the same time or after the change of /WE to low level, the I/O pins will  
remain high impedance state.  
3. When /WE is at low level, the I/O pins are always high impedance. When /WE is at high level,  
read operation is executed. Therefore /OE should be at high level to make the I/O pins high  
impedance.

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 not initialized until the  
reset signal is received. Reset operation must be executed immediately after power-on for devices  
having reset function.

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

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 the customer's equipment shall be done under the full responsibility  
of the customer. NEC Corporation assumes no responsibility for any losses incurred by the customer or third  
parties arising from the use of these circuits, software, and information.  
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: Aircraft, 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.
