Low Voltage Data Retention
Intersil CMOS RAMs are designed with battery backup in
mind. Data Retention voltage and supply current are guaran-
teed over the operating temperature range. The following
rules ensure data retention:
1. The RAM must be kept disabled during data retention. This is ac-
complished by holding the E2 pin between -0.3V and GND.
2. During power-up and power-down transitions, E2 must be held
between -0.3V and 10% of VCC.
3. The RAM can begin operating one TAVAX after VCC reaches the
minimum operating voltage of 4.5V.
