Datasheet
● LVCC circuit
LVCC (Vcc-Lockout) circuit prevents data rewrite action at low power, and prevents wrong write.
At LVCC voltage (Typ. =1.9V) or below, it prevent data rewrite.
● Noise countermeasures
○ Vcc noise (bypass capacitor)
When noise or surge gets in the power source line, malfunction may occur, therefore, for removing these, it is
recommended to attach a bypass capacitor (0.1μF) between IC Vcc and GND. At that moment, attach it as close to IC as
possible. And, it is also recommended to attach a bypass capacitor between board Vcc and GND.

● Recommendable application circuit
1. It is recommended to attach bypass condensers on
power line.
Vcc2(3.3V)
Vcc1(1.8V)
2. Be sure to make CSB pull up. At power on, mat cause
the abnormal function.
3. Please make LDOEN pull down.
4. If EEPROM malfunction occur by Hi-Z input of the
microcontroller part connected with SO, please make
SO pull up or pull down.
5. Please attach capacity at V OUT terminal. Outputs

● Notes for use
? Absolute maximum ratings
We pay attention to quality control of this IC, but if there is special mode exceeded absolute maximum rating, please take
a physical safety measures. Because we can’t specify short mode and open made, etc.
? Heat design
In consideration of permissible dissipation in actual use condition, carry out heat design with sufficient margin.
? 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.
? Common impedance
Please pay attention to V CC and GND wiring. For example, lower common impedance and to make wiring think, etc.
? GND electric potential
Set the voltage of GND terminal lowest at any action condition. And, please make pin except GND voltage of GND or
over.
? Test of set base
If low impedance pin connect with capacity at test of set base, please discharge each test progress to stress IC. Please
embroider earth for static electricity measures at structure progress, pay attention to carry and conservation. When set
base connect with test base at test progress, please connect and remove from power OFF.
