Operational Notes
The X25040 powers-up in the following state:
The device is in the low power standby state.
A HIGH to LOW transition on
CS
is required to
enter an active state and receive an instruction.
SO pin is high impedance.
The “write enable” latch is reset.
Data Protection
The following circuitry has been included to prevent
inadvertent writes:
The “write enable” latch is reset upon power-up.
A WREN instruction must be issued to set the “write
enable” latch.
CS
must come HIGH at the proper clock count in
order to start a write cycle.
