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.

INTRODUCTION
Target Readers
Purpose
www.DataSheetO4Urg.caonmization
This manual is intended for user engineers who wish to understand the functions of
the 78K0S/KA1+ in order to design and develop its application systems and
programs.
The target devices are the following subseries products.
78K0S/KA1+: µPD78F9221, 78F9222
This manual is intended to give users on understanding of the functions described in
the Organization below.
Two manuals are available for the 78K0S/KA1+: this manual and the Instruction
Manual (common to the 78K/0S Series).

How to Use This Manual
It is assumed that the readers of this manual have general knowledge of electrical
engineering, logic circuits, and microcontrollers.
To understand the overall functions of 78K0S/KA1+
Read this manual in the order of the CONTENTS.
How to read register formats
The name of a bit whose number is enclosed with <> is reserved in the
assembler and is defined in the C compiler by the header file sfrbit.h.
To learn the detailed functions of a register whose register name is known
See APPENDIX C REGISTER INDEX.
To learn the details of the instruction functions of the 78K/0S Series
Refer to 78K/0S Series Instructions User’s Manual (U11047E) separately
available.
To learn the electrical specifications (target) of the 78K0S/KA1+
See CHAPTER 20 ELECTRICAL SPECIFICATIONS (TARGET VALUES).
