Notes:
1. To prevent an erroneous operation, be sure to maintain SCL=SDA="H", and set the FeRAM in an inactive
state (standby mode) before and after power-on and power-off.
2. Powering on at the intermediate voltage level will cause an erroneous operation; thus, be sure to power up
from 0 V.
3. Enter all signals at the same time as power-on or enter all signals after power-on.
•Power-On and Power-Off Sequences

After Power-Off, terminal state
When MR44V064A only goes power-off while the other IC’s on I2C bus are active, all the input pins including
I/O pin of MR44V064A must be GND level.
