Memory IC FAQ

How does the device achieve automatic power-down?

Power-down occurs automatically when CE1 is HIGH or CE2 is LOW, placing outputs in a high-impedance state and reducing standby current significantly.

What is the data retention voltage?

Data is retained at a minimum VCC of 1.5 V, allowing for battery backup scenarios where main power drops below the operating range.
