①Using EEPROM PART
In case of using EEPROM part, be sure to raise Vcc1 up to operating voltage. In this time,
Vcc2 has no connection with operating.

②Using LDO REGULATOR PART
In case of using LDO regulator part, be sure to raise Vcc1 and Vcc2 up to operating voltage.
After rising Vcc1, wait 15msec and rising LDOEN. When LDOEN is raised, Vcc1 must be operating voltage.

◇ I/O APPLICATION CIRCUIT
Pull up resistor is indispensable condition.
When CSB is "H" during power ON/OFF, error operating and writing is protected.
○PULL UP RESISTOR OF CSB PIN
The pull up resistor is needed in order to prevent error operating and writing from happening.
Decide the value of this resistor (Rup) properly, considering VOH, IOH characteristics of controller.

Example) When Vcc=5V, VILE=1.5V, VOLM=0.4V,
IOLM=2mA, according to ①,

Rpu ≧
2×10-3
∴ Rpu ≧ 2.5[kΩ]
Rpu ≧
If the Rpu is under the conditions of the equation ①,
VOLM is 0.4V or more.
If the Rpu is under the conditions of the equation ②,
VILE(=1.5V) is VOLM or less.
◇CAUTIONS ON USE
(1) Absolute maximum ratings
If the absolute maximum ratings such as impressed voltage and operating temperature range and so forth are exceeded,
LSI may be destructed. Do not impress voltage and temperature exceeding the absolute maximum ratings. In the case
of fear exceeding the absolute maximum ratings, take physical safety countermeasures such as fuses, and see to it
that conditions exceeding the absolute maximum ratings should not be impressed to LSI.
(2) GND electric potential
Set the voltage of GND terminal lowest at any action condition. Make sure that each terminal voltages is lower than
that of GND terminal.
(3) Heat design
In consideration of permissible dissipation in actual use condition, carry out heat design with sufficient margin.
(4) Terminal to terminal shortcircuit and wrong packaging
When to package LSI onto a board, pay sufficient attention to LSI direction and displacement. Wrong packaging
may destruct LSI. And in the case of shortcircuit between LSI terminals and terminals and power source, terminal
and GND owing to foreign matter, LSI may be destructed.
(5) Strong electromagnetic field
Use in a strong electromagnetic field may cause malfunction, therefore, evaluated design sufficiently.
