Request for your special attention and precautions in using the technical information and
semiconductors described in this book
(1) If any of the products or technical information described in this book is to be exported or provided to non-residents, the
laws and regulations of the exporting country, especially, those with regard to security export control, must be observ ed.
(2) The technical information described in this book is intended only to show the main characteristics and application circuit
examples of the products, and no license is granted under any intellectual property right or other right owned by our
company or any other company. Therefore, no responsibility is assumed by our company as to the infringement upon any
such right owned by any other company which may arise as a result of the use of technical information described in this
book.
(3) The products described in this book are intended to be used for standard applications or general electronic equipment
(such as office equipment, communications equipment, measuring ins truments and household appliances).
Consult our sales staff in advance for information on the following applications:
x Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment, combustion equipment,
life support systems and safety devices) in which exceptional quality and reliability are required, or if the failure or
malfunction of the products may directly jeopardize life or harm the human body.
x Any applications other than the standard applications intended.
(4) The products and product specifications described in this book are subject to change without notice for modification and/
or improvement. At the final stage of your de sign, pur chasing, o r use of the p roducts, therefore , ask for the mo st up-todate Product Standards in advance to make sure that the latest specifications satisfy your requirements.
(5) When designing your equipment, comply with the range of absolute maximum rating and the guaranteed operating condi-
tions (operating power supply voltage and operating environment etc.). Especially, please be careful not to exceed the
range of absolute maximum rating on the transient state, such as power-on, power-off and mode-switching. Otherwise,
we will not be liable for any defect which may arise later in your equipment.
Even when the products are used within the guaranteed values, take into the consideration of incidence of break down
and failure mode, possible to occur to semiconductor products. Measures on the systems such as redundant design,
arresting the spread of fire or preventing glitch are recommended in order to prevent physical injury, fire, social damages, for example, by using the products.
(6) Comply with the instructions for use in order to prevent breakdown and characteristics change due to external factors
(ESD, EOS, thermal stress and mechanical stress) at the time of handling, mounting or at customer's process. When
using products for which damp-proof packing is required, satisfy the conditions, such as shelf life and the elapsed time
since first opening the packages.
(7) This book may be not reprinted or reproduced whether wholly or partially, without the prior written permission of Mat-
sushita Electric Industrial Co., Ltd.

Please note that the consumption current values provided in this application note are reference
values. Microcomputer power consumption varies largely depending on the nature of the
application (program) as well as the peripheral circuits connected to I/O pins.
For obtaining actual power consumption, please mount the finished device on a product and
measure the power consumption. And then mark it on the face plate and calculate a battery
drive time.
Dual oscillation circuit provides low voltage and low power consumption operation, and highspeed processing.
By selecting between the two oscillation modes according to the current state, power
consumption in standby state can be reduced to as low as 1/330th of that in regular operation,
and data processing can be performed at high speed of up to 4 MHz.
Even at the moment when the oscillation circuit switches modes, all data is preserved, and input
and output are kept stable.
