Memory IC FAQ

Is the Quad Enable (QE) bit configurable?

No, the QE bit is permanently set to 1 by default and cannot be changed, ensuring IO2 and IO3 pins are always enabled for Quad operations.

What is the typical standby current consumption?

The typical standby current is 11μA, while the deep power-down current is typically 1μA.

How many security registers are available?

The device contains two 1024-byte security registers that can be locked using One-Time Programmable (OTP) lock bits.
