◇Caution

（１） Power on Reset

Please keep the terminal RESETX at the Low level when the power supply starts. After completely starting up 3.3V system power supply, afterwards,

please make the terminal RESETX High level after 5us after the oscillation of the system clock is steady. Moreover, please make the terminal

RESETX Low level during 5us or more when resetting it while operating.

（２） About compatibility in USB memory device and SD memory card

According to the file structure and communication speed of an USB memory, SD memory card, this LSI might not play back correctly.

（３） About turning on the power supply

Current rush might flow momentarily by the order of turning on the power supply and the delay in IC with two or more power supplies, and note the

capacity of the power supply coupling, the power supply, and width and drawing the GND pattern wiring.

（４） About absolute maximum rating

When the absolute maximum rating such as the applied voltage and the ranges of the operating temperature is exceeded, LSI might be destroyed.

Please apply neither voltage nor the temperature that exceeds the absolute maximum rating. Please execute physical measures for safety such as

fuse when it is thought to exceed the absolute maximum rating, and examine it so that the condition to exceed the absolute maximum rating is not

applied to LSI.

（５） About GND Voltage

In any state of operation must be the lowest voltage about the voltage of the terminal GND. Please actually confirm the voltage of each terminal is not

a voltage that is lower than the terminal GND including excessive phenomenon.

（６） About design of overheating malfunction preventive circuit

Please design overheating malfunction preventive circuit with an enough margin in consideration of a permissible loss in the state of using actually.

（７） About the short between terminals and the mounting by mistake

Please note the direction and the gap of position of LSI enough about LSI when you mount on the substrate. LSI might be destroyed when mounting

by mistake and energizing. Moreover, LSI might be destroyed when short-circuited by entering of the foreign substances between the terminal and

GND, between terminals, between the terminal and the power supply of LSI.

（８） About operation in strong electromagnetic field

Use in strong electromagnetic field has the possibility of malfunctioning and evaluate it enough, please.
