NOTES FOR CMOS DEVICES
1 VOLTAGE APPLICATION WAVEFORM AT INPUT PIN
Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the
CMOS device stays in the area between VIL (MAX) and VIH (MIN) due to noise, etc., the device may
malfunction. Take care to prevent chattering noise from entering the device when the input level is fixed,
and also in the transition period when the input level passes through the area between VIL (MAX) and
VIH (MIN).
2 HANDLING OF UNUSED INPUT PINS
Unconnected CMOS device inputs can be cause of malfunction. If an input pin is unconnected, it is
possible that an internal input level may be generated due to noise, etc., causing malfunction. CMOS
devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed
high or low by using pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND
via a resistor if there is a possibility that it will be an output pin. All handling related to unused pins must
be judged separately for each device and according to related specifications governing the device.
3 PRECAUTION AGAINST ESD
A 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 when it has occurred. Environmental control must be
adequate. When it is dry, a humidifier should be used. It is recommended to avoid using insulators that
easily build up 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

benches and floors should be grounded. The operator should be grounded using a wrist strap.
Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for
PW boards with mounted semiconductor devices.
4 STATUS BEFORE INITIALIZATION
Power-on does not necessarily define the initial status of a MOS device. Immediately after the power
source is turned ON, devices with reset functions have not yet been initialized. Hence, power-on does
not guarantee output pin levels, I/O settings or contents of registers. A device is not initialized until the
reset signal is received. A reset operation must be executed immediately after power-on for devices
with reset functions.

PREFACE
Readers
This manual is intended for users who wish to understand the functions of the
V850ES/KE1+ and design application systems using these products.
Purpose
This manual is intended to give users an understanding of the hardware functions of the
V850ES/KE1+ shown in the Organization below.
Organization
This manual is divided into two parts: Hardware (this manual) and Architecture (V850ES
Architecture User’s Manual).
Hardware

How to Read This Manual It is assumed that the readers of this manual have general knowledge in the fields of
electrical engineering, logic circuits, and microcontrollers.
To find the details of a register where the name is known
Refer to APPENDIX DCaRtaESGhISeTeEt4RUI.NcDoEmX.
To understand the details of an instruction function
Refer to the V850ES Architecture User’s Manual.
Register format
The name of the bit whose number is in angle brackets (<>) in the figure of the
register format of each register is defined as a reserved word in the device file.
To understand the overall functions of the V850ES/KE1+
Read this manual according to the CONTENTS.
To know the electrical specifications of the V850ES/KE1+
Refer to CHAPTER 27 ELECTRICAL SPECIFICATIONS (TARGET).
The “yyy bit of the xxx register” is described as the “xxx.yyy bit” in this manual. Note with
caution that even if “xxx.yyy” is described as is in a program, however, the
compiler/assembler cannot recognize it correctly.
