be low when HOLD is first pulled low and SCK must
also be low when HOLD is released.
The HOLD input may be tied high either directly to VCC
or tied to VCC through a resistor.
Operational Notes
The X25128 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.
